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...

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...
