Background
The polyester yarn is cotton yarn used for producing polyester, the polyester is fiber prepared by spinning a polymer, and the polyester is fiber produced by taking polyethylene terephthalate as a raw material, which is called PET fiber for short. Commonly known as terylene in China. 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.
The polyester staple fiber is staple fiber of several centimeters to ten and several centimeters, and is fiber obtained by spinning polyester (polyethylene terephthalate, PET for short and polymerized by PTA and MEG) into a tow and cutting the tow.
The polyester yarn adopts a normal spinning process, but because the polyester yarn is easy to generate static electricity, a large amount of spinning oil is added during the production of the polyester yarn, and the spinning oil is easy to cause the polyester yarn to deteriorate during transportation or storage, so that the production cost of the polyester yarn is increased.
