Abstract:

The alkali deweighting treatment on polyester filament warp knitted fabric could get better wearability. The effects of alkali dosage, handing time, liquor ratio and handing temperature were discussed by orthogonal test. This study finally obtain the optimal processing parameter of the alkali peeling, alkali dosage is 25g/L, handing time is 50min, liquor ratio is 1:15, handing temperature is 110℃. . After that, the fabric which go through the above process was made fabric style and SEM test. The evaluation of the fabric after alkali treatment was soft feel, luster and touch were approach to cotton fabrics. This treatment make the cotton effect better.

Key words: cotton like, alkali reduction treatment, treatment parameter, warp knitting, style and hand feeling, glossiness
