Method 1. Combustion method. When the cotton burns, the flame is smooth, take a small amount of fiber and ignite it, and observe the ash left by it. If it is loose, the cotton will be broken when twisted; on the contrary, if it melts first, it forms agglomerated adhesion together. The solid one is p...
Influence of PET Aggregate Structure on Physical Properties of Polyester Fully Drawn Yarn ①The greater the degree of molecular orientation of PET, the greater the breaking strength of the fiber, and the smaller the elongation at break; ②the greater the crystallinity of the PET molecule, the stronger...
The organizational structure of polyester chemical structure The basic composition of polyester is polyethylene terephthalate, molecular formula HO-H2C-H2C-O[-OC-Ph-COOCH2CH2O-]n, because there are a lot of ester groups on the molecular chain, it is called polyester fiber (PET). ), the chemical stru...
Application of ropes and cables: ropes, cables, sails and fishing gear made of this fiber are suitable for marine engineering and are the initial use of this fiber.

Classification, properties and uses of polyester filament 1. Classification There are many varieties of polyester filament, which can be divided by product, use, linear density, gloss, and twisting method. Commonly used is divided by product, the main products are as follows: primary silk Undraw...
FDY is recommended for fully drawn yarns. Full-length yarns are also known as polyester (PFY) yarns or SDY yarns. These are full-length wires that are welded by various methods such as spanning, welding, and soldering. All new yarns contain only polyester filaments. These very strong polyester fiber...
