High-strength polyester staple fiber

Abstract

The invention discloses a high-strength polyester staple fiber which comprises a polytetrafluoroethylene coating, a synthetic fiber layer and a nylon cloth layer. The inner surface of the polytetrafluoroethylene coating is provided with a natural fiber layer, one end of an artificial fiber layer is provided with an inorganic fiber layer, a regenerated fiber layer is fixedly connected with the synthetic fiber layer, one end of the synthetic fiber layer is provided with a linen cloth layer, one end of the cotton cloth layer is provided with a wool fabric layer, and one end of a polyester fiber layer is provided with a gambiered canton gauze layer. The high-strength polyester staple fiber is provided with the polytetrafluoroethylene coating, the synthetic fiber layer and the nylon cloth layer, can have the advantages of corrosion protection and resistance to various organic solvents, has excellent high temperature and low temperature resistance, non-toxic property and electrical insulating property, can improve the hand comfort, has good dyeing performance, good air permeability, heat dissipation property, high strength and good elasticity, prevents mildew and moths, is suitable for different working conditions and has a better use prospect.

Description

technical field [0001] The invention relates to the field of polyester staple fiber yarns, in particular to a high-strength polyester staple fiber yarn. Background technique [0002] Polyester staple fiber refers to the cotton yarn used in the production of polyester. Polyester is a kind of fiber made of polymer by spinning. At present, it mostly refers to the fiber produced from ethylene phthalate as raw material, referred to as PET fiber. Commonly known as polyester in our country. Usually the so-called yarn actually refers to the general term of yarn and thread, which is defined as follows in clothing material science: yarn is arranging many short fibers or filaments in an approximately parallel state, and rotating and twisting along the axial direction, and the composition has a certain strength. A slender object with a linear density; and a thread is a strand formed by twisting two or more single yarns. Yarn is a thin strand made of cotton, wool, hemp, chemical fiber,...

AI Technical Summary

Problems solved by technology

[0003] The existing polyester staple fiber thread has certain disadvantages when it is used. There is no PTFE coating, it does not have the characteristics of acid and alkali resistance, various organic solvent resistance, and the advantages of high temperature resistance, low temperature resistance, non-toxic electrical insulation , does not have waterproof function, no regenerated fiber layer, poor hand feeling, poor dyeability, not good air permeability, no synthetic fiber, not high enough strength, heavy quality, poor elasticity, not mildew proof, for this reason, We propose a polyester yarn with heat dissipation and anti-corrosion functions
