A Study on the Alkali Hydrolyzed Properties of Polyester Fabric by Various Denier Reduction Range
감량가공기계에 따른 폴리에스터 직물의 감량특성에 관한 연구
Abstract
In order to make a silk-like polyester fabric, polyester fabrics were treated with a several weight reduction machines such as tank type, liquor flow type and C.D.R at the field condition. The results were as followings : The weft density of treated polyester fabric showed different tendency according to the used the weight reduction machine and the rate of weight loss. Namely, at 6.5% weight loss, the weft density of fabric treated with tank and liquor flow type increased by 1 pick/inch and 2 picks/inch, respectively, and decreased by 4 picks/inch in case of treated with C.D.R type. With the increase in the rate of weight loss, the air permeability of treated fabric increased, and the K/S value of dyed fabric decreased. The overall tendency of the air permeability and the K/S value of treated polyester fabric increased in the order of the tank type, liquor-flow type and C.D.R type. The tensile strength of polyester fabric treated with C.D.R had lower value than that of the other type. It is assumed that this result is attributed the decreasing of the cross point of the warp and weft direction.
