Polytrimethyene terephthalate-based tricot suede fabric having high shrinkage recovery

摘要

PURPOSE: A tricot suede cotton fabric based on polytrimethylene terephthalate is provided with improved elasticity and flexibility while involving simplified processing steps. CONSTITUTION: A tricot knitted fabric is made by knitting an ultra-fine polytrimethylene terephthalate(PTT) filament yarn, which has a total fineness of 50-150 denier and a mono-filament fineness of 0.01-0.2 denier after the alkali finishing, a PTT filament yarn, which has a total fineness of 50-150 denier and a mono-filament fineness of 2-3 denier after the alkali finishing, and a spandex(polyurethane) yarn, which has a total fineness of 10-80 denier. The tricot knitted fabric undergoes the processes of raising, alkali finishing, dyeing, and buffing to form a tricot suede cotton fabric.
