Warping – Needs no adjustment, because of low strength CV % warp breakages are practically nil. Warping can be at very high speeds upto 1200 meters per minutes
Sizing – Stretch ratio should be reduced to 0.6 to 0% (i.e. practically no stretch)
Weaving – Reduce density of weft yarn (pick / inch) by 3%. Because of very good evenness, low imperfections and CV% of count and strength, looms can be worked upto 650 picks per minute and hence so there is tremendous gain in loom efficiency
Because of low shrinkage of Air Jet Yarns, the fabric should be processed with minimum tension on warp
Jet scouring is preferred as compared to jiggers (more relaxation time will give better results)
During drying there should be an overfeed of 4-6%
Use of silicon based softener, non-ionic or cationic softener will give cotton-touch handle
For better results in processing, following sequences are recommended:
Temperature - 180oC Exposure - 25 to 30 seconds Over Feed - 4 to 5 %
Finishing with Cationic softener 5 to 10gms per litre and Micro Amino 25 to 30gms per litre. If extra soft handle of fabric is required, weight reduction process varying from 6% to 12% is recommended
Avoid singeing. Mild singeing can be done at high speeds and low exposure because the hairiness in Air Jet Yarn is already low
