Technical Field

The invention relates to the technical field of yarns, in particular to an antistatic polyester yarn and a production process of the antistatic polyester yarn.

Background

The polyester yarn is a yarn spun by taking polyester as a raw material, the polyester is a fiber prepared by spinning a polymer, and the polyester yarn is a fiber produced by taking polyethylene terephthalate as a raw material, which is called PET fiber for short and is commonly called polyester. By "yarn", it is meant the collective designation of "yarn" and "thread", as it is commonly referred to, as defined in the clothing materials science, as follows: "yarn" is an elongated object formed by arranging a plurality of short fibers or filaments in an approximately parallel state and twisting them by rotation in the axial direction to have a certain strength and linear density; and "thread" is a strand formed by twisting two or more single yarns. The yarn is a fine yarn (usually used as a raw material for weaving) obtained by elongating and twisting a fiber such as cotton, wool, hemp, chemical fiber, etc., and a plurality of fine yarns (called a yarn) obtained by twisting a fine yarn material such as cotton, hemp, silk, wool, etc.
