High shrinkage polyester fibre low-elater with PTT service performance and preparing technique thereof

Abstract

The invention provides a high shrinkage polyester drawn textured yarn with PTT operation performance and a manufacturing method of the high shrinkage polyester drawn textured yarn. The invention is realized by the following procedures: a group of or a plurality group of technique parameters and related product data is or are obtained by adopting an orthogonal experiment statistic method; the most reasonable technique parameter and product performance index among above data are obtained; optimization is carried out continuously on the basis, thus obtaining the technique parameter of the invention and producing related products at the same time. The curling ratio of the polyester high elastic DTY can reach up to 54 percent which is close to 60 percent of curling ratio of the PTT fiber, and the production cost of a textile enterprise can be effectively reduced by substituting the PTT fiber with the polyester high elastic DTY.

Description

technical field [0001] The invention relates to a polyester low elastic yarn with high crimping performance and a production process, belonging to the technical field of chemical fiber production. Background technique [0002] With the improvement of living standards, more and more weaving manufacturers began to choose to use PTT fiber. The PTT fabric has a thick feel and is comfortable to wear on the elbows, knees, shoulders and other moving parts. However, the manufacturing cost of PTT fiber is relatively high, which limits its use as a conventional textile raw material, and causes some high-grade fabrics and related products that use PTT as raw material to have high prices and cannot be used more widely. Contents of the invention [0003] The invention provides a high-elastic DTY product and a production process thereof which use relatively cheap PET fiber to replace PTT, and whose crimp index is required to be close to that of PTT. [0004] The present invention is a...
