Problems solved by technology

[0002] At present, the application of polyester low elastic yarn fabrics is more and more extensive, and in view of the characteristics of 35D / 144F polyester yarn raw materials, there are mainly the following problems in the production process: 35D / 144F polyester yarn itself has a twist, which is easy to kink during warping ;Because the yarn of 35D / 144F polyester yarn is relatively thin, the multifilament is only 35D, while the single fiber is 0.243D, and the tension in the drying room is small, and it is easy to appear in the drying room after being blown by hot air during drying. Problems such as kinks and broken ends; in addition, due to the thinner yarn and high F number, in the sizing process, the existing sizing process easily leads to insufficient permeability and poor covering rate, and problems such as hair warp and broken warp during the weaving process

Abstract

The invention discloses a production process of 35D / 144F polyester low-stretch yarn fabric. Through the process adjustment of the four processes of warping, sizing, paralleling and weaving, kinks, twists and end breaks are reduced, the sizing rate is improved, and the sizing rate is reduced. The phenomenon of hair warp and broken warp improves the production efficiency and ensures the product quality.
