Producers of Printed Beachwear Fabrics by Gruppo MarediModa Technical Conditions of Supply for Printed Elastic Fabrics with elastane
The Gruppo MarediModa companies, inspired by the technical supply conditions of knitwear fabrics, have drawn up the following conditions to which they will comply when producing and supplying printed elastic fabrics containing elastane. As well as acting as a point of reference, these conditions also represent a valid means of support and the parameters within which our customers expectations regarding the supply of printed fabrics should fall..
TECHNICAL CONDITIONS OF SUPPLY OF PRINTED ELASTIC FABRICS TOLERANCES Slight variations in quality, colour, size, weight and some printing defects, the consequence of the printing transformation process, are inevitable. The limits of tolerance are: Defects: Allowance for piece of 70 m: 5 unresolved defects for all-over designs; 4 for panel designs. Height: ± 2% of the usable printed height declared by the supplier for elastane + synthetic fibres. ± 4% of the usable height declared by the supplier for elastane + other fibres (cotton, viscose, silk, etc.). Length: The fabrics are measured on inspection machines that are periodically calibrated and checked. However given the characteristics of the fabric a certain amount of adjustment is considered normal. The following tolerances are acceptable: Elastane/Polyamide over 150 g/m 2 : ± 2% of the size stated by the supplier. Elastane/Polyamide up to 150 g/m 2 : ± 3% of the size stated by the supplier. Elastane/Cotton: ± 4% of the measurement stated by the supplier. Panel Patterns: Taking the measurement of the repeat as a basis, one might find variations, even on the same piece, in repeat from + 3% to - 6%. Weight: ± 6% for fabrics above 150 g/m 2 or ±10% for fabrics up to 150 g/m 2 in relation to the declared weight. Dimensional Stability: Elastane/Polyamide: ± 6% when washed at 40 C according to ISO 6330(2000) or equivalent norms. Elastane/Cotton: 8% according to the above-mentioned norm. Colourfastness: The colourfastness of reference standard pieces applies. Any special requests of acceptability values should be discussed beforehand between the parties. Quantities supplied: ± 10% for orders up to 1000 m. ± 5% for orders of more than 1000 m. Conformity check: International ISO regulations on colourfastness are considered the only reference for obtaining reliable data Light ISO 105-B02 (1994/Amd2:2000) Water ISO 105-E01 (1994/Cor1:2002) Washing at 40 C (with soap) ISO 105-C01 (1989) Sea water ISO 105-E02 (1994/Cor1:2002) Swimming pool water ISO 105-E03 (1994) Perspiration A+B ISO 105-E04 (1994/Cor1:2002) Rubbing S+U ISO 105-X12 (2001) The explanatory table on the last page compares the ISO standards with the corresponding ones in force in various countries. Bow and Skew: Owing to the characteristics of the fabrics and the printing processes, a tolerance of 5% is acceptable for the entire width of the textiles, with consequent distortion in the pattern (e.g. a striped or panel pattern). Special Techniques: A few recent technical developments have led to a number of fabrics being placed on the market whose properties are impossible to define by the usual parameters. In such cases, the garment-maker should ascertain beforehand, with the required tests, the suitability of the product for its intended use, assuming all risks and responsibility for its use. Sensitivity of colours: All prints, and in particular those with a white background or with fluorescent colours, must be kept in a dry place, away from sources of heat and adequately protected by wrapping that prevents light and atmospheric pollution (gas fading, air conditioning, etc.) from altering their colours. I In particular, it is advisable not to leave the fabrics on the cutting tables near warehouses with access to transport or
during periods when the air conditioning is being used (from cold to hot air and vice versa). Reproducibility of printed fabrics on different mediums and/or in subsequent orders: Printed fabrics are subject to many irregular variables. A change in tone between the first sample, industrial production and subsequent repetitions is to be considered admissible and acceptable. Also admissible is a difference in tone and look of the same design and its variation on different fabrics. Matching of plain colours, printed fabrics and fabrics with a different composition: Owing to the diversity of the working processes, it is not possible to repeat the identical shades of the plain colours on the prints. However it is important to note that if matching is essential, the plain colour should follow the printed colour. In the case of overprinted plain fabrics, matching with the plain colour cannot be guaranteed.
