Properties of Polyester Filament

1. General properties of polyester fibers (1) Strength. The fiber strength is high, generally 4.5~8cN/dtex, and the high-strength fiber is 5.6~8.OcN/dtex. Due to its poor hygroscopicity, the wet strength and dry strength are basically the same. (2) Touch the amount. The initial modulus of polyeste...

How to distinguish "cotton" and "polyester"?

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

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...

How is UHMWPE fiber used in civil applications?

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. Widely used in negative force marine ropes, heavy duty ropes, salvage ropes, towing ropes, sailing ropes and fishing lines. The breakin...

What is fully drawn yarn (FDY)?

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...
