Preparation method of modal polyester fiber yarn

Abstract

The invention discloses a modal polyester fiber yarn, which is made from the following raw materials in parts by weight: 5-20 parts of modal and 70-80 parts of polyester. The invention also provides the application of the yarn in the preparation of fleece-proof fabrics. The yarn of the present invention has soft hand feeling, high yarn breaking strength and good abrasion resistance. At a temperature of 180-200°C, the polyester fiber will expand due to the increase of crystal grains, increasing the fabric woven by the yarn. The tightness of the fabric, so as to achieve the anti-velvet effect.

Description

technical field [0001] The invention relates to the textile field, in particular to a fiber yarn and its preparation method and application. Background technique [0002] Modal is a kind of cellulose regenerated fiber with high wet modulus. The raw material of the fiber is European beech wood, which is first made into wood pulp, and then processed into fiber through a special spinning process. The raw materials of this product are all natural materials, which are harmless to the human body, can be decomposed naturally, and are harmless to the environment. There is also no pollution during the entire production process of the fiber. [0003] The amount of short fibers and fibers of modal fibers are easily damaged, and the number of neps and hairiness is large during spinning. [0004] Polyester: [0005] 1. High strength. The short fiber strength is 2.6-5.7cN / dtex, and the high-strength fiber is 5.6-8.0cN / dtex. Due to its low hygroscopicity, its wet strength is essential...

AI Technical Summary

Problems solved by technology

[0008] 4. The surface of polyester is smooth, the internal molecules are closely arranged, and there is no hydrophilic structure between the molecules, so the moisture regain is very small and the hygroscopicity is poor.

[0012] 8. Poor dyeability

[0013] But the fabric feel of all polyester is poor, dyeability and hygroscopicity are all relatively poor, so this field needs to develop a kind of modal polyester fiber yarn with good feel and fabric strength
