3 LINK / TRENDS & MARKETS Trends in the spinning of quality yarns Spinning mills are facing considerable challenges. The prevailing trends have been apparent at the major machinery trade shows. What solutions can customers expect from Rieter? Fig. 1 The new E 80 comber is even more productive than the predecessor model and sets new standards in mill operations in terms of yarn quality and flexibility. Rieter has attended three major textile machinery exhibitions in the past 12 months: ITMA Europe Barcelona (Spain), ITM Istanbul (Turkey) and ITMA Asia Shanghai (China). The latter was less international in scope than the trade fairs in Barcelona and Istanbul. At exhibitions held in such rapid succession it is rather rare for fundamental innovations to be on show. For example, most exhibitors at ITMA Asia showed the same products that they had already displayed at ITMA Europe and in Turkey. Rieter is an impressive exception to this. A completely new product was introduced to the market in the shape of the E 80 comber. This machine is the response to the high quality demands imposed on yarns. Blends and manmade fibers continue their advance High cotton prices in recent years have left their traces in the textile supply chain. A trend toward slightly coarser yarns is apparent. There is a slightly rising trend in semi-combed yarns, in which carded and combed slivers are blended on the draw frame. The trend toward blends is continuing. Blends with viscose are important alongside those with polyester. Rieter s sales organization is aware of these trends and provides expert advice both for new installations and for upgrades. Various processes are available for fiber blends. Depending on mill requirements, a choice can be made between weighing hopper blending, intimate component blending or draw frame blending. Automation in response to shortage of personnel Whereas the large markets in Asia were long able to count on cheap labor, spinning mills in these countries are now faced with the completely new challenge that personnel are in short supply. Rieter secured innovation leadership in the field of automation at an early stage. At the ITMA in Hanover in 1979 Rieter attracted considerable attention with the first roving frame featuring a fully automated doffer, the F 3/1 model. Again in Hanover, in 1991, Rieter surprised visitors with the ROBOfil device for the automatic piecing of ends down on ring spinning machines. By that time the Autodoffer was already taken for granted. Rieter s great experience in automation is reflected in the reliability of its solutions. Rieter also provides a global service network of highly competent technical specialists and repair units for electronic components.

4 4 LINK /2012 TRENDS & MARKETS Sustainability in spinning The major apparel manufacturers, traders and increasingly also governments are requiring more and more extensive efforts to be made in the field of environmental protection. One feature of this trend are the many new labels relating to this topic. Almost every company, association or industrial federation is launching a label. In spinning there are two important aspects which contribute not only to sustainability, but also to reduced costs: high raw material utilization and low energy consumption. Rieter has already being pursuing both of these goals for many years. Rieter relies on facts and figures and can demonstrate the improvement in the energy consumption of Rieter machines in recent decades. Outlook for 2013 The wide fluctuations in the cost of raw materials, the unavailability of personnel and increasing demands with regard to environmental protection are global trends that will continue to challenge spinning mills in years to come. A volatile business environment calls for a high degree of flexibility and expertise in order to maintain and improve one s competitiveness. Successful spinning mills therefore rely on Rieter s comprehensive offering of products and services. This embodies the cooperative competence package for a successful future together. This issue of link includes several articles featuring specific examples of energy and raw material savings. Please also note Rieter s reprint on the topic of energy efficiency, which can be ordered via info@ rieter.com quoting reference Energy efficiency reprint Fig. 2 Good training facilities contribute to employee loyalty and preserve the value of the installation. Rieter provides comprehensive training after installation and also later when the plant is in operation. Edda Walraf Head Technology and Marketing Winterthur edda.walraf@rieter.com

Yarn parameters and fabric appearance Laboratory values such as yarn regularity and imperfections (Fig. 3) are evidently not reflected in the appearance of the finished fabric in the case of Com4 jet yarn. The untreated material in all knitted structures displayed a very uniform fabric appearance. The fabric surface is much more even and uniform compared to knitwear made from ring-spun or compact yarns. The yarn structure and the larger yarn diameter of Com4 jet yarns are the reasons for this. About twothirds of the fibers form the parallel yarn core. The front portion of the remaining fibers is incorporated in the yarn core, and the rear portion is wrapped around the parallel yarn core. Impressive in the knitting mill The Com4 jet yarns impressed in the knitting mill due to the very well integrated fiber ends, which resulted in reduced incidence of dust and fiber fly. The specific hairiness of the Com4 jet yarns, featuring many short hairs less than 3 mm long, creates the nap on the surface of the knitted fabric which is largely responsible for the fabric s hand. However, the hairs are so short that no unwelcome fiber pills can be formed. Fabric testing Various textile technology tests have been conducted in order to make a neutral appraisal of wear behavior in terms of practical capability. Fabric appearance and hand Twisting of the knitted fabric (seam slippage) Color-fastness Pilling behavior Fig. 1 Structure of a Com4 jet yarn spun on the J 20 air jet spinning machine. Fig. 2 Project criteria and knitted fabric structures in the extensive knitting trial. The largest area of application for Rieter Com4 jet yarns spun on the J 20 air-jet spinning machine is currently in knitwear. Yarn quality is impressive with very well integrated fiber ends, low hairiness featuring short, protruding fibers, and high regularity (Fig. 1). South Pacific viscose fibers with a staple length of 38 mm and a fiber count of 1.3 dtex were spun into a Rieter Com4 jet yarn with a yarn count of Ne 30 (Nm 50) in an extensive series of tests. This yarn was Reference quantities customary on the market, such as Marks & Spencer standards, are used to assess wear behavior.

6 6 LINK /2012 TRENDS & MARKETS Limited twisting in the knitted fabric It can often be observed that the side seams of T-shirts twist in one direction after washing the T-shirt looks inferior. In the case of Com4 jet yarn the finished goods have little or no twist, i.e. the seams have little tendency to slip (Fig. 4). This is a major advantage of Com4 jet yarn compared to conventional yarns, where the tendency to twist is usually much greater. Fabric made from Com4 jet yarn looks high-quality even after repeated washing. Exceptionally good pilling behavior ICI pilling tests with and without fibers in the pilling box recorded exceptionally high pilling resistance for viscose yarn with readings of 4, 4-5 and 5. The best reading that can be achieved in this test is 6. However, pilling behavior according to Martindale also shows excellent results. Even after 5 washing cycles the pilling tendency is strikingly low. Pills are already visible after the first wash in many T-shirts purchased today. Com4 jet products retain their superior characteristics throughout their lifetime. 100 % CV, Nm 50 (Ne 30) Rieter Com4 jet yarn Yarn regularity CV [%] Thick places +50 % [1/km] Thin places -50 % [1/km] Neps +200 % [1/km] Uster hairiness Strength [cn/tex] Fig. 3 Test results of Ne 30 Com4 jet yarn.

Higher overall efficiency of the knitting machine is apparent. The good dye receptivity results in dyestuff savings or offers potential for abbreviating the process. There is no evidence of color fading, even after repeated washing cycles. Manufacturing fabrics from Com4 jet yarns contributes to the conservation of resources and the environment. From the standpoint of the consumer, Com4 jet knitwear is synonymous with superior pilling resistance, minimum seam slippage/twisting and maximum color-fastness. The yarn structure results in a uniform fabric appearance and a softer, more supple drape of the knitted fabric. The excellent wear properties of the garment, its wash-fastness and low pilling tendency enhance customer benefits Marc Schnell Product Management Air jet Spinning Winterthur marc.schnell@rieter.com Fig. 4 Finished articles made from Com4 jet yarn display very little or no twisting / seam slippage.

7 LINK / TRENDS & MARKETS Maximum energy efficiency in yarn manufacturing As a systems supplier, Rieter is familiar with the main influencing variables of relevance for saving energy in yarn manufacturing, and focuses its attention closely on these in its product development. Full potential can be realized with an integrated Rieter installation. Fig. 1 Saving energy in spinning operations protects nature and cuts costs. Fig. 2 Energy consumption a comparison of the 4 spinning systems. Fig. 3 The finer the yarn count, the higher the energy costs per kg of yarn. Minimum environmental pollution, higher efficiency in power generation, maximum savings in power consumption, optimum utilization of raw materials, maximum productivity these are all factors that contribute to sustainability. Rieter has already recognized this in recent decades and systematically taken it into consideration in the development of its spinning systems. Whatever system Rieter s customers opt for, all the machines and equipment contribute to sustainability in the textile supply chain. If they are effective together, the potential for energy savings can be exploited to the full. The final spinning systems differ widely in terms of specific energy consumption due to the processes used. As a supplier of all 4 spinning processes, Rieter can respond to the differing conditions prevailing in the customer s operations and recommend the ideal process, also with reference to energy consumption. Comparative energy consumption of the spinning systems Differences in energy costs from the blowroom to the finished yarn can be illustrated using a mill in Indonesia as a practical example (Fig. 2). An Ne 30 weaving yarn in a 50:50 Lyocell/cotton blend was chosen. If energy costs are considered in isolation, regardless of the yarn properties produced, the most economical process is rotor spinning, followed by air-jet spinning. In comparison, ring and compact spinning have the highest energy costs. Air jet spinning is the lowest-cost process, with energy costs accounting for 18 % of yarn manufacturing costs. Energy costs account for 19 % per kilogram of yarn spun in compact spinning and 20 % in rotor and ring spinning. Energy consumption increases for finer-count yarns (Fig. 3). Consumption rises most steeply for rotorspun yarns, and least for air jet-spun yarns. Air jetspun yarn is already the yarn with the lowest energy consumption per kilogram of production at Ne 40 (15 dtex), followed by carded rotor-spun, ring-spun and compact yarn. If an Ne 50 (12 dtex) yarn is being produced the difference is even greater. Air jet spinning is clearly the most energy-efficient process for this yarn count. The rotor, ring and compact spinning processes are virtually identical in this count range, although it should be pointed out that Ne 50 rotor-spun yarns are not customary in practice.

It must also be borne in mind here that air jet-spun yarn coarser than Ne 24 is hardly ever produced. A system is only as good as its individual components In its machine development, Rieter has already systematically focused its attention for many years on reducing energy consumption per kilogram of output. Each machine operates with maximum energy efficiency in itself and is unrivaled as an integrated system. Rieter cards energy saving in carding Between 1992 and the current generation of C 70 cards, energy consumption per kilogram of carded sliver produced has been reduced by more than 70 % (Fig. 4). A pioneering advance in energy saving was achieved in 2002 when the C 60 model was launched on the market. The key to success here was the increase in the card s working width from mm to mm. This recipe for success has been taken a step further in the current C 70 generation of machines with the largest active carding area compared to all other cards on the market. The large carding area enables higher output to be achieved with the same sliver quality. The increase in energy consumption necessary for this high output was disproportionately small. That is the precondition for the low energy consumption per kilogram of sliver. Rieter draw frames taking energy requirements into account as early as the design phase During a comparison in a Turkish customer s mill when drafting a sliver to 5 dtex, a production speed of 500 m/min was initially tested. In comparison with a European competitor the energy consumption of the RSB-D 45 was 10 % lower per kilogram of carded sliver produced. At a draw frame speed of 850 m/ min the total consumption of the Rieter RSB-D 45 was kwh/kg of yarn. That is still 9 % less than for the competitor. In principle, the simpler the drive concept (Fig. 5), the less energy is required to set the elements in motion. Despite fewer motors, the intelligent transmission layout means that the RSB-D 45 needs only few drive elements, such as belts and tension pulleys.

Between 1988 and today energy consumption in combing has been reduced by a total of 48 % (Fig. 6). Motion and functions have been optimized and perfectly coordinated by means of C A P D Q (computeraided process development). Over the years combing quality has been improved by means of the highest precision while systematically reducing energy consumption at the same time. Rieter ring spinning machines higher output is the decisive factor Up to 40 % of yarn manufacturing costs in a conventional ring spinning mill are energy costs. The spindle drive concept featuring 4-spindle belt drive or central tangential belt drive is not merely a philosophical issue, but a matter of reducing energy costs (Fig. 7). You don t have to be a machine manufacturer to recognize that a greater angle of wrap considerably reduces slippage between belt and spindle. The 90 angle of wrap of Rieter s 4-spindle belt drive is ideal for slipfree traction. Contact pressure does not have to be increased so much in order to ensure slip-free traction. No tangentially driven ring spinning machine manages to beat the benchmark. Rieter compact spinning machines perforated drum outperforms aprons in terms of energy consumption Since the launch of the compact spinning machine Rieter has reduced energy consumption per kilogram of yarn produced. First of all the smaller wharve diameter of the spindle was introduced. With the K 45 the vacuum supply has been optimized and the entire aerodynamics of the spindle and the draw frame drive have been adapted. Between the launch of the first compact spinning machine and the current K 45 model energy consumption has been reduced by 14 %. Rieter is the only manufacturer to offer a compacting unit featuring a perforated drum with direct drive, at the same time using a combined extraction duct for the extraction tubes and for compacting. The perforated drum unit with direct drive reduces energy requirements and eliminates any flexing of the otherwise customary aprons (Fig. 8). Rieter air-jet spinning machines the intelligent concept The Rieter J 20 air-jet spinning machine is the latest member of Rieter s stable of final spinning machines. Compared to other spinning technologies, it requires up to 35 % less space for the same yarn output. This reduced volume of space, i.e. air, does not have to be air-conditioned. For the spinning mill this means a reduction of up to 28 % in annual energy costs for air conditioning.

The latest generation succession has been a case in point, with a significant optimization of the energy balance. The main reasons for this are the efficient vacuum system of the R 60 with the intelligent filter cleaning system and the good yarn quality that can be achieved with limited vacuum due to the new spinning box, energy-saving motors of ideal dimensions and the economical cooling system for the inverters. Practical examples in this case in India back up the theory (Fig. 10). With the same spinning conditions in terms of yarn twist and draw-off speed the energy consumption measured for the R 60 rotor spinning machine is 12 % lower than for the latest generation of European competitors. In this case this results in cost savings of 4.3 million Indian rupees or Swiss francs per machine and year. Systems advantage Besides many other advantages, Rieter s integrated system from blowroom to final spinning consumes significantly less energy than a comparable competitor s spinning mill. In one case in India consumption per kilogram was 5 % lower for the Rieter ring spinning installation compared to a competitor s integrated system. This is equivalent to savings of some Swiss francs per year and integrated system. Rieter has published further detailed studies in a reprint. Contact Rieter via info@rieter.com quoting Energy efficiency reprint we will be pleased to send you this brochure The sum of conceptual energy-saving measures is clearly apparent in practice (Fig. 9). At the same production speed as competitors, the air-jet spinning machine achieves a reduction in power consumption per kilogram of yarn of up to 11 %. If production speed is increased, a reduction of as much as 14 % is possible in practice. Iris Biermann Senior Marketing Manager Winterthur iris.biermann@rieter.com

14 14 LINK /2012 TRENDS & MARKETS Media transformation a customer survey on the subject of media consumption At the beginning of the last century the radio was propagated as the new medium. After that television, videotext, the Internet, etc., revolutionized the world. Nowadays social networks are changing the way information is consumed. In response to this rapid transformation Rieter launched a customer survey on the topic of media consumption in order to establish the information needs of customers and readers. Encouraging level of participation Rieter conducted an online survey of customers reading habits in January Customers expressed their opinions and offered hints and suggestions of topics they were interested in. Rieter was pleased with the 10 % response rate and sincerely thanks everyone who took part. Online media are dominant According to the survey, the Internet is the most frequently used medium for gathering information on technical and technological subjects, followed by product brochures and trade journals. The survey also revealed how media utilization is changing. For example, more than 60 % of respondents read trade journals online and some 50 % also read brochures and other documentary material on this medium. Increasing focus on profitability Technological fields of application and new machine functions have always been popular subjects. The increased interest in economic aspects is remarkable. Machinery manufacturers are being called upon to assist in optimizing installations as a whole and in boosting profits. For Rieter, in its role as a systems supplier which is best placed to optimize an entire installation in technical, technological and economic terms, this is an important task and part of its day-today business. Rieter s customer magazine 'link' and news of products and services can be subscribed to in the News Center on the Rieter website ( Rieter makes a distinction in its external communications between information with and without a criti cal time element. Current topics with a critical time element are distributed to the media worldwide by Rieter via press releases, so that customers and readers are informed as rapidly as possible. The contents of a press release can usually only be exploited briefly within two to three months the information is no longer of relevance for the target group. Contents without a critical time element are usually scientific papers such as findings from textile technology trials or reports of experience in mill practice. The usefulness of these articles for readers is considerably longer-lasting than for daily topical themes.

15 LINK / PRODUCT NEWS The E 80 comber quality meets flexibility With the launch of the E 80 comber, Rieter is again shifting the boundaries of what is possible in combing. New superlatives in performance are being achieved in terms of quality, output and economy. Fig. 1 The new E 80 comber maximum flexibility in terms of quality, productivity and economy. Flexibility is the ability to adapt to changing circumstances and conditions. In our fast-moving times flexibility is essential, also in spinning mills, which must be able to respond quickly to changes in the market or raw material. The new E 80 comber (Fig. 1) supports the customer in this as never before. C A P D Q the foundation for a new combing experience For the first time in the history of high-performance combing, the improved combing geometry of the E 80 comber enables a 130 circular comb (Ri-Q-Comb) to be used without having to make concessions in the nip rate. 130 means an increase in the combing area of some 45 % compared to the predecessor model (90 ). The possible increase of up to 60 % in the number of points per circular comb that this brings enables the fibers to be combed out even more thoroughly than with the 90 circular combs used to date. The result is a high-quality combed sliver which is reflected primarily in an improvement in yarn quality. Cus tomers can thus choose whether they wish to exploit this quality advantage (E 80 Quality) or to convert it into higher output (E 80 Productivity) or improved raw material utilization (E 80 Yield). E 80 Quality (Fig. 2) In principle, the focus in combing is on refining the raw material and thus improving the end product. No spinning mill would comb and accept a relatively high loss of material if no significant enhancement of yarn quality were to be achieved as a result. The E 80 focuses precisely on this point. The new comb geometry enables yarn quality to be improved by up to 20 % compared to the predecessor model with the same output (Fig. 3). No other comber available on the market permits this symbiosis of superior quality and high economy at the same time.

The advantages for the customer are: up to 20 % fewer imperfections compared to the E 66 / E 76 comber up to 30 % fewer imperfections compared to other combers on the market maximum uniformity of the finished goods greater flexibility in the choice of raw material E 80 Productivity (Fig. 4) References to combing output to date primarily meant the number of nips per minute. The fact that batt weight and feed rate are at the same time also equally important factors with regard to a comber s production performance was usually neglected. With the advent of the E 80 there is again more emphasis on these two factors. The improved combing technology of the E 80 means that there is no longer any barrier to using a higher feed rate, i.e. the quantity of lap now fed per nip. Output can therefore be increased in an energy-saving and economical manner without also having to compromise on the quality achieved to date (Fig. 5). A finer subdivision of feed rates also helps to increase flexibility still further. In conjunction with a high batt weight of up to 80 g/m, depending on raw material, the E 80 achieves production figures of up to 2 tonnes/day, which have been out of reach in practice to date. The productivity of a comber can also be improved by the use of large can formats or automated lap piecers. It has recently become possible to use cans mm in diameter exclusively with Rieter combers; this halves the number of can changes and thus reduces operator effort by some 10 %. Together with the familiar and unique ROBOlap automated lap piecing system, this enables machine efficiencies of up to 96 % to be achieved.

17 LINK / PRODUCT NEWS Fig. 8 The potential of the E 80 comber at a glance. The advantages for the customer are: up to 2 tonnes/day of combed sliver up to double the output compared to other manufacturers superior price/performance ratio up to 10 % lower labor costs E 80 Yield (Fig. 6) The largest cost factor in combing is fiber waste. In times of widely fluctuating cotton prices the quantity of noil removed during combing is therefore of even greater economic importance. The less material has to be combed out to achieve the required level of yarn quality, the more economically a combed yarn can be produced. The E 80 offers a unique advantage here, since the achievable improvement in yarn quality can be converted into raw material savings of up to 2 % compared to the predecessor model (Fig. 7). Compared to other combers available on the market, raw material savings of as much as 4 % can be achieved. The larger combing area and the increase in combing action associated with this also enable raw material of lower quality to be used, depending on the application, without having to make concessions on the quality produced to date. The advantages for the customer are: up to 4 % raw material savings compared to other manufactures up to 20 % lower yarn manufacturing costs high material utilization up to 10 % lower energy costs E 80 comber flexibility at the highest level The E 80 brings an enormous increase in flexibility in combing (Fig. 8).

18 18 LINK /2012 PRODUCT NEWS The major importance of energy consumption in ring and compact spinning Energy-saving is on everyone s lips, whether in the household or in industry. It is a key factor in yarn manufacturing costs. In ring spinning, energy costs account for more than 25 % of production costs. Energy savings of 10 % here mean a reduction of 2.5 % in customers yarn manufacturing costs. Rieter is continuously working to reduce energy consumption and recent comparisons show significant savings versus other suppliers. The importance of energy costs is obvious from a study of the manufacturing costs of ring-spun yarns, taking an Ne 30 yarn in Asia as an example in this case (Fig. 1). They are the second-largest item (26 %) as a proportion of total costs, after total capital expenditure on buildings, machinery, spare parts and accessories, and before waste and auxiliary costs and personnel expenses. Rieter s calculations are always based on the cost per kilogram of yarn produced. In a comparison with other suppliers, the speeds, availability, maintenance effort and service life of the machine must therefore always be taken into account. For example, many Rieter customers operate their ring spinning machines at speeds 10 % faster than machines of other suppliers. Superior efficiency at maximum speeds High-quality components, resolute, purposeful developments and ideally designed software effectively help to reduce energy consumption and thus yarn manufacturing costs. Accessories enable the energy consumption of Rieter machines in spinning mills to be predicted accurately. Maximum loading of elements such as motors, inverters, etc., is already taken into account during the design process in order to enable higher speeds to be achieved. In certain cases this results in higher installed power, but indisputably lower energy consumption per kilogram of yarn produced. The procedure also takes into account the fact that the motors are always operating in the highest efficiency range. Higher speeds always result in higher energy consumption A clear disadvantage of higher speeds is the physically inevitable increase in energy demand. This rises by the square of the rise in speed. Rieter can therefore only influence the level of the curve and does this very successfully (Fig. 2). Customer s comparison confirms the low energy consumption of Rieter ring spinning machines Rieter has been able to demonstrate impressively the advantages of Rieter machines in a comparative trial in China during the past year. All leading ring spinning machinery manufacturers have been involved. With constant outline parameters for all participants, there were differences in spindle speed, yarn quality

19 LINK / PRODUCT NEWS Breakdown of yarn manufacturing costs Capital costs 40 % Auxiliary costs 9 % Waste costs 23 % Personnel costs 2 % Energy costs 26 % Fig. 1 With an Ne 30 yarn, energy costs account for almost 30 % of yarn manufacturing costs. Ne 30, 100 % cotton, knitting yarn 1,7 and numbers of ends down. The differences in energy consumption were even greater than the differ ences in spindle speeds achieved. The yarn count range was medium to fine; spindle speed was raised as high as possible without having a negative impact on yarn quality or increasing the number of ends down. The main points are dealt with in detail below. Energy consumption is strongly affected by tube length One competitor used special, shorter-format tubes in order to reduce energy consumption. This is a very efficient approach, since most energy is required to drive the cops. If a shorter tube is used, less yarn and thus less material has to be driven on average. Hosny A. Soliman conducted the fundamental investigation at the FIT in Zurich for Rieter. This study showed that energy consumption per kilogram of yarn is more than 8 % lower if the tube, i.e. winding height, is 20 mm shorter. Energy consumption [kw/kg yarn] 1,6 1,5 1,4 1,3 1,2 1, Local supplier G 32-5 % Rieter G 32-8 % Spindle speed [rpm] Despite this advantage, this competitor consumed 12 % more energy than Rieter s ring spinning machine. As a result of the shorter tubes a lower mean production speed was achieved with the same maximum speed, since the cop carrier accounts for a larger proportion of the yarn mass. This results in an average rotation speed 500 rpm lower or 2.8 % less output. The more frequent cop changes reduced efficiency by a further 3 %. To summarize, this competitor required 12 % more energy at a comparable quality level and lost more than 3 % output (Fig. 3). Fig. 2 The G 32 ring spinning machine.

Despite lower energy consumption, higher speeds on Rieter ring spinning machines Competitors found it difficult to equal Rieter s spindle speeds. A European supplier achieved a maximum speed of only rpm and thus approx. 6 % lower output with his locally manufactured model. Since 11 % more energy per kilogram of yarn was already required at this lower speed, this can be extrapolated with a further 9 % to Rieter s level, producing a total difference of 20 %. Each of this competitor s spindles therefore delivered 6 % less output with 11 % higher energy costs. If the speed of Rieter s machine is reduced to the same level, energy costs are 20 % lower, equivalent to approx. 8 % lower yarn manufacturing costs for the Rieter ring spinning machine. Asian competitors ring spinning machines displayed even higher energy consumption ( %) at lower production speeds (Fig. 4). Since these suppliers customers accepted higher numbers of ends down and lower yarn quality, a compromise always had to be found between spindle speed, quality requirements and energy consumption.

Rieter K Fig. 5 K 45 compact spinning machine with solid metal cylinder and an extraction duct saves up to 70 % energy. The K 45 compacting unit the basis of energy-efficient compacting. The K 45 maximum compacting with minimum energy consumption The differences in energy consumption are even clearer in the compacting process. It is well known that most compacting systems employ aprons as well as operating with independent vacuum generators for compacting and extraction. Several operate with one unit per section with approx. 0.5 kw installed power in addition to normal extraction for the extraction tubes. Others use a centralized unit which is rather more efficient. All apron solutions require an effective minimum compacting output of 6 watts per spindle (7-10 watts were also measured). If this is extrapolated to the machine as a whole with spindles, the outcome is almost 10 kw for compacting alone, in addition to normal extraction. Rieter s solution is distinctly different here. A solid metal cylinder is used as the compacting unit rather than aprons that are susceptible to wear. However, the low energy consumption is an even greater advantage. Rieter is well known for its large-format duct with an ideal cross-section. This enables the duct to be used for both extraction and compacting, which is an enormous advantage with regard to energy consumption. Only an additional 2 kw for extraction are required for spindles compared to a conventional ring spinning machine. This results in an advantage of at least 8 kw per machine compared with other systems, equivalent to more than 10 % of the total consumption of the compact spinning machine (Fig. 5). 8 kw per machine and hour add up to kwh/ year (8 500 hours) or correspond to savings of euros at energy costs of 0.10 euros/kwh. However, Rieter s K 45 compact spinning machine has even more to offer. Top-quality compacted yarn is produced even at speeds that are often 10 % higher than those of other compact spinning machines or conventional ring spinning machines. Spindle speeds 10 % higher mean at least 10 % higher output with little maintenance and wear compared to other suppliers. "The Comfort of Competence" Rieter, the only manufacturer of all four spinning systems, incorporates know-how from all machinery sectors in its machine development in order to achieve the very best for its customers. Top-quality yarn at maximum speeds is only one argument here. Added to this is the lowest energy consumption for a further reduction in yarn manufacturing costs. Rieter also sets quality standards at high production speeds a further key element underpinning Rieter s slogan "The Comfort of Competence" Andreas Hellwig Product Manager Ring and Compact Spinning Winterthur andreas.hellwig@rieter.com

Annual savings in cotton consumption of 3.4 million Indian rupees Price of cotton consumed [million rupees/year] Cotton consumption in INR/year Increase in yarn yield Before technological optimization After technological optimization Cotton consumption in tonnes/year Cotton consumption [tonnes/year] A leading spinning mill in South India, which commissioned a complete Rieter installation in 2008, found itself faced with a low yarn yield when processing Indian cotton. The customer therefore asked Rieter for assistance in solving this problem. The Indian team at Rieter Customer Technology accepted the cus tomer s challenge and helped to achieve the desired yarn yield. This is one of the advantages of Rieter s "Comfort of Competence" for customers. After conducting a detailed analysis of the customer s machinery portfolio and process flow, various fine adjustments were made to the cards (C 60 v7), draw frames (SB 20) and combers (E 32 and E 75).

In addition to even more consistent yarn quality, the number of maintenance cycles can be significantly reduced, thus enabling labor savings to be made. Rieter compacting unit with perforated drum and suction insert. It is a well-known fact that in Rieter s compact spinning process, in contrast to ring spinning, after the draw frame the fibers are fed over a perforated drum in which a vacuum is created. This produces a dense fiber bundle with uniformly oriented, parallel fibers. Marginal fibers can therefore be integrated virtually completely into the fiber bundle, which increases material utilization (strength) and reduces hairiness. Reduced downtimes, higher system availability The benefit for customers is very soon apparent. A reduction in the number of maintenance cycles results in higher machine efficiency.

26 26 LINK /2012 RIETER INSIDE QR codes small aids with a big impact Attentive readers have noticed them long ago the small, square images resembling checkerboards placed alongside the articles in the 'link' customer magazine or on Rieter advertisements in trade journals. These so-called QR codes make it easy for readers to obtain more in-depth information about the topic in question. QR code simply scan to try it out! Really simple using a mobile telephone to scan a QR code. QR (Quick Response) codes can be compared to the bar codes that are scanned at any supermarket checkout to read the price of a product into the cash register. Compared to a bar code, however, instead of price information QR codes contain a link to a website (hyperlink), addresses, contact data or simply just a text. And you don t need a special scanner for these QR codes, just a commercially available smartphone (mobile telephone with a camera and various supplementary functions) and appropriate software (app). Added value for readers Rieter aims to make reading more interactive and give readers the opportunity to find out more. Unfortunately, to date it has not been possible to display videos and animation sequences in a magazine. However, QR codes now enable animation sequences relating to an article to be viewed on a smartphone. With the QR codes on Rieter advertisements in trade journals readers thus find their way quite easily to more information on the product in question, e.g. to brochures, machine datasheets or detailed descriptions. How are QR codes scanned? Owners of mobile telephones can best inform themselves via manufacturers websites or the providers of the device. The precondition for scanning a QR code is a camera integrated in the mobile telephone and an app (specific software) which can read out the pictorial data. In the case of ios, Android, Nokia or Blackberry devices, these apps can be downloaded from the relevant app shops often free of charge. Once the app is installed on the mobile telephone the code in question can simply be scanned with the camera.
