Abstract:
1. A process of preparing a cleansing polyester fabric, comprising the steps of: (a) weaving a warp and a weft to obtain a woven fabric, (b) scouring and reducing the woven fabric at the same time; (c) heat-setting the woven fabric obtained from step (b); (d) extracting sea components from the heat-set woven fabric (c) in an aqueous alkaline solution with reduction rate of 28-38% on a basis of the fabric weight; (e) dying the fabric obtained from step (d); and (f) heat-setting the dyed fabric to obtain the cleansing polyester fabric having a weight of 80-200 g/m wherein the warp is composed of a sea-island conjugated yarn having 0-10% shrinkage rate in boiling water or its false twisted yarn, the sea-island conjugated yarn consists of a sea component and an island component, and ultra fine yarns (monofilament fibrils) having a monofilament fineness of 0.001 to 0.1 deniers after extracting the sea component, and wherein the weft is composed of a false twisted mixing yarn prepared by interlacing (folding and false twisting simultaneously) a sea-island conjugated yarn having 0-10% shrinkage rate in boiling water and a polyester multifilament having 10-50% of shrinkage rate in boiling water, the sea-island conjugated yarn consists of a sea component and an island component, and ultra fine yarns (monofilament fibrils) having a monofilament fineness of 0.001 to 0.1 deniers after extracting the sea component.
