Polyester fiber, commonly known as "polyester"

Polyester fiber, commonly known as "polyester". It is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dihydric alcohol, and belongs to high molecular compound. Invented in 1941, it is currently the largest variety of synthetic fibers. The big...

What are the classifications of carpet yarn?

1. Nylon: good wear resistance, easy to clean, but easy to deform, easy to generate static electricity, will partially dissolve in case of fire. 2. Polyester: The abrasion resistance is second only to nylon, heat resistance and light resistance. 3. Polypropylene: light weight, good elasticity, hig...

POY and FOY in continuous filament polyester sewing thread

Continuous filament polyester can be supplied in many forms, but the most common for industrial use are partially oriented yarn (POY) and highly oriented yarn (FOY). What is Partially Oriented Thread (POY)? The yarn facing section is made by melting and extruding a polyester chip or flake (melt cy...

How carpet yarn is made

Let's start with nylon slices. Particles in the shape of rice grains are our nylon chips, which can be spun into monofilament threads after high temperature processing. After twisting the monofilament, it can become the carpet yarn we generally use! CARPET YARNS AND RUG YARNS Zhejiang Hengyuan C...

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...

What are the characteristics of polyester filament? What are...

Abstract: Polyester filament, as the name suggests, is made of polyester filament. Polyester is an important variety of synthetic fibers, and is the trade name of polyester fibers in my country. The so-called polyester filament is a filament with a length of more than one kilometer. The filament is ...

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 ...

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...
