METHOD FOR PRODUCING FINE DENIER COVERING YARN FOR STRETCH MIXTURE FABRICS

摘要

The present invention relates to a method for producing the covering's, the supply of a polyurethane filament of 18~20d and the draft ratio after stretching of 2.0 to 3.0, per 1m of the synthetic fiber filament 20~30d the polyurethane filaments twisted 1000-1500 as to the number of covering the stretch union cloth covering three count's manufacturing method for which is characterized, according to the invention has excellent elasticity, without reduction in strength by making the fineness of three synthetic capture the covering yarn, and the air permeability and a high stretch rate US the recovery rate can provide a low count covering four years that can be used as a blouse that uses the perspective effect of low density.
