What kind of fabric is polyester?

Polyester, an important variety in synthetic fibers, the trade name of polyester fibers

say. With purified terephthalic acid (PTA) or dimethyl terephthalate

(DMT) and ethylene glycol (EG) as raw materials through esterification or ester exchange and

Fiber-forming polymer obtained by polycondensation reaction-

polyethylene terephthalate

Diol esters (PET), fibers made by spinning and post-processing.

Classification of polyester fabrics

Polyester includes: staple fiber, drawn yarn, textured yarn, decorative filament,

Industrial filaments and various differentiated fibers.

(1) Polyester staple fiber fabric

1. According to physical properties: high, medium, low strength, medium elongation, high modulus

type, high strength and high modulus type

2. According to processing requirements: cotton type, wool type, linen type, silk type,

3. According to use: clothing, cotton, decorative, industrial

4. According to function: cation dyeable, hygroscopic, flame retardant, colored, anti-

Pilling, antistatic

5. According to the fiber section: special-shaped wire, hollow wire.

(2) Polyester filament fabric

1. As-spun silk: undrawn silk, semi-pre-oriented silk, pre-oriented silk, high

Oriented yarn

2. Drawing silk: drawing silk, full drawing silk, full drawing silk

3. Textured yarn: conventional textured yarn, stretched textured yarn, air textured

Silk.

Advantages of polyester fabrics

1. Good chemical resistance, acid and alkali damage to it is not large, no

Afraid of mold and insects.

2. The synthetic fiber fabric has good heat resistance and thermoplasticity.

3. High strength and elastic recovery ability, strong and durable, wrinkle-free

hot feature.

4. Good light resistance, comparable to acrylic fabrics.

Disadvantages of polyester fabrics

1. Poor hygroscopicity. Polyester fabric, poor hygroscopicity, will be stuffy when wearing

It is easy to be electrostatically charged and contaminated with dust, but it is very easy to dry after cleaning.

The wet strength hardly decreases, and it does not deform, and the wearability is very good.

2. Poor dyeability. No specific staining gene, staining is more difficult,

The dyeability is poor, but the color fastness after dyeing is very good, and it is not easy to fade.

3, easy to pilling. One of the synthetic fiber products, used for a period of time

After that, the ball will be played.

4. Poor melting resistance. Poor melting resistance, easy to shape in case of sparks, soot, etc.

Make holes and avoid contact with cigarette butts and sparks when wearing.
