Problems solved by technology

[0004] At present, the conventional fiber-opening process is a high-temperature strong alkali fiber-opening method. For example, Chinese patent CN101429689A discloses a superfine fiber and its production method. Stable and uneven, it is also easy to decompose ordinary PET fibers, resulting in large fiber damage, poor physical properties, high production costs, large energy consumption, large sewage discharge, and pollution to the environment

Abstract

The invention discloses a polyester fabric and a preparation method thereof. Soluble high-shrinkage polyester yarns of which the filament number is below 0.4 denier are adopted in at least one of the warp and weft directions of the fabric; and the splitting rate of the fabric is over 80 percent, and the tearing strength of the fabric is over 9.8 N. The cloth cover of the fabric combines fashion and functionality, and the polyester fabric is an ideal material for sports and relaxation. After the polyester fabric is subjected to single-surface calendaring, one surface is smooth and glossy, and the other surface offers a weak hair or chamois matte feel. In addition, the polyester fabrics do not have any splitting agent, and are simple in operation and low in cost.

Description

technical field [0001] The invention relates to a polyester fabric and a preparation method thereof. It specifically relates to a fabric containing soluble high-shrinkage polyester fiber and a preparation method thereof. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for clothing fabrics. Textile fabrics that are soft to the touch, functional and fashionable are favored by consumers. Judging from the current trend of the clothing market, textile fabrics with special styles have become the first choice of consumers and have great market demand. [0003] However, such textile fabrics currently on the market generally have the problems of insufficient softness, insufficient water pressure resistance, unqualified tear strength, and single cloth style. The unique style and excellent physical properties of this fabric mainly lie in the control of a series of engineering of material selection, weaving ...
