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

Embodiment Construction

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0027] A modal polyester fiber yarn is spun from the following raw materials in parts by weight: 5-20 parts of modal polyester fiber and 70-80 parts of polyester.

[0028] Among them, modal fiber has a length of 35-37mm and a fineness of 0.15tex; polyester is a polyester staple fiber with a length of 35-37mm and a fineness of 0.15tex, and the fineness of modal polyester fiber yarn is 5-10tex.

[0029] The following is the spinning process using modal fiber as raw material:

Abstract

The invention discloses modal polyester fiber yarn. The modal polyester fiber yarn comprises, by weight, 5-20 parts of modal and 70-80 parts of polyester. The invention further provides application of the yarn to preparation of a down-proof fabric. The yarn is soft in touch, high in breaking strength and good in abrasion resistance; under the temperature of 180-200 DEG C, fiber expansion is caused due to crystal grain increase of the polyester fiber, fabric tightness of the fabric woven of the yarn is improved, and according the down-proof effect is achieved.

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...
