Abstract:

Fabrics made by polyester filament with the simulated cotton appearance have large dimensional changes, which increase difficulties of setting processing parameter during fabric production. To control the fabric dimension and find the most optimized process, three kinds of fabric structure, four kinds of on-loom density and two kinds of finishing process were selected and studied. The effect of three factors on the density of fabric was also analyzed. Based on above analysis, it can be concluded that shrinkage of fabrics in weft direction is greater than that in warp direction. The proper structure was the reverse locknit stitch, the on-loom density was 20 row/cm, the final process includes warping → knitting → washing → pre-sizing → dying → sizing → finished product. The mass oj the fabric was 184.3 g/㎡. The shrinkage on weft direction and shrinkage on warp direction was 24 % and 38.9 %, respectively. The fabric width was 160 cm.
