For 75D-250D, weft yarn two is the composite filament that sea island filament and high-shrinkage polyester low stretch yarn are combined, yarn count 80D-250D.
The sea island filament of weft yarn two and the F number ratio of high-shrinkage polyester low stretch yarn are 2:1-4:1.Present invention discover that in this F number ratio
Sea island filament bring soft fluffy after fibrillation can be played in example range reduces the effect of hair loss, and can combine high-shrinkage polyester shape
At knitting rib-loop appearance.This is because high-shrinkage polyester F number is smaller in this F number proportional region, it is heated after shrinking
Woven fabric is just made to have the distinctive extensibility of apparent knitting fabric and resilience.Sea island filament F number is larger, during fibrillation
Lye mainly plays a part of to dissolve extra large part in sea island filament, washs that corrasion is smaller to high convergency, a small number of high-shrinkage polyesters
It can play a supporting role, reduce the loss of fabric broadwise strength.
Singeing step uses two forward one-reverses, speed 100-110m/min；The fire extinguishing of amylase working solution is padded, 4-6h is banked up.
Concentration of caustic soda 30-40g/L in kiering process kiering working solution.
