1 SOFTNESS Hard facts? Stuart Gregory (Petrofer)

2 PAPERmatters 2018! The Presentations Stuart Gregory Petrofer Stuart is a qualified production engineer who has supplied technical support and sales of paper process chemicals for over 30 years. He has supported chemical business with on site experience in many European countries. Chemical sales experience in all paper making industries including converting. The author may be contacted via the PITA Office Telephone: or info@pita.co.uk

3 Stuart Gregory Managing Director Petrofer UK PLC Roger Altenburg Paper Specialist Petrofer Germany PAPERmatters! 2018 Conference 1

4 PAPERmatters! Conference 2018 Lancaster SOFTNESS Hard facts? P the process step that makes tissue unique! PAPERmatters! 2018 Conference 2

5 Tissue Sheet Dryer Coating Dryer Metal Shell Creping Doctor Blade PAPERmatters! 2018 Conference 3

6 Top view of facial tissue M a c h i n e D i r e c t i o n Creped Tissue Photomicrographs Fibers Perpendicular to the surface add "softness." Edge view of two ply creped facial tissue. This is an exceptionally soft product. Pictures of a tissue with a good and a poor creping structure PAPERmatters! 2018 Conference 4

9 Picture of a spray boom with nozzles Tissue sheet Release layer COATING Phosphate layer Yankee surface <- release <- process chemicals <- phosphate <- fines, hemicellulose <- synthetic base coating <- inorganic contaminants PAPERmatters! 2018 Conference 7

10 Coating Creping blade action on coating: Yankee Tissue Blade a. Blade runs on top of the coating poor creping, less softness, risk for chatter marks b. Blade runs in the coating matrix ideal, excellent creping, good blade and cylinder life c. Blade runs on yankee surface sparks, poor creping, bad blade life and wear, cylinder damage Paper sheet at this stage is dry (3-8% moisture) Needed: dry adhesion Necessary: for creation of micro crepe (softness) The paper web is soon released The paper web goes deeply into the blade gap angle Function of the coating/ adhesion Creping at low adhesion Creation of coarse crepe (macro crepe) Creping at high adhesion Creation of fine crepe (micro crepe) PAPERmatters! 2018 Conference 8

11 Yankee Surface Hard Coating Soft Coating The larger the pocket angle, Impact of blade geometry & coating adhesion on tissue softness the more softness and the smaller the wavelength of the tissue Small pocket angle rough creping Large pocket angle fine creping is constant PAPERmatters! 2018 Conference 9

12 Stickout/ blade thickness: α Stickout Increasing stickout or decreasing the blade thickness causes more bend resulting in lower α (= more softness) Utilise a Softener? softeners are available for stock or spray application PAPERmatters! 2018 Conference 10

13 Utilise a Softener? Application system in Tissue Converting rotary atomiser Parameters of influence at point of application - Viscosity of product - Droplet size - Spray mist - Control of spray mist and quantity applied How to measure softness? TSA Tissue Softness Analyser PAPERmatters! 2018 Conference 11

14 How to measure softness? I Sound Measurement II Deformation Measurement Real Softness TS7 Smoothness/Roughness TS750 Stiffness D 1 2 How to measure softness? TSA Tissue Softness Analyser The three basic parameters of handfeel: Real Softness Smoothness/ Roughness Stiffness Calculated handfeel numbers HF based on standard models or adapted to the respective customers handfeel panel PAPERmatters! 2018 Conference 12

15 Conclusion: SOFTNESS Hard Facts?: The theories can all be validated as factual, but there is still much that is unknown There are so many influences on softness not one parameter alone is the key influence Understanding and optimising of all the machine variables is vital to a soft sheet Coating chemistry must be robust enough to tolerate variances in external factors Softness can now be mechanically measured and is not a human subjective value The challenges for softness are getting more complex with market demands, speed and productivity requirements, changing furnish and chemical restrictions influencing the process. Many parameters can be measured, computer modelled, internet 4.0 connected, but human experience and a gut feel are still required The holy grail of supersoft tissue is an ongoing challenge and changes daily! Wherever you are, count on PETROFER S PAPER TEAM!!! Expertise, Quality & Dedication We listen, We develop, We deliver PAPERmatters! 2018 Conference 13
