Common are Suit Polyester Canvas Bleached Fabric.


Classification of polyester fabric:


Polyesters include: short fibers, drawn yarns, textured yarns, decorative filaments, industrial filaments, and various differentiated fibers.

(A) polyester short fiber fabric

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

2. According to processing requirements: cotton, wool, hemp, silk;

3. According to use: clothing, cotton, decoration, industrial;

4. By function: cationic dyeable, hygroscopic, flame retardant, colored, anti-pilling, antistatic

5. Divided by fiber cross section: shaped wire, hollow wire.

(B) polyester filament fabric

1. Primary yarn: undrawn yarn, semi-pre-oriented yarn, pre-oriented yarn, high-oriented yarn

2. Stretched wire: drawn wire, fully drawn wire, fully drawn

3. Modified yarn: conventional textured yarn, stretch textured yarn, air textured yarn.

Polyester fabric advantages

1, good chemical resistance, acid and alkali damage to it is not great, and not afraid of mold and insects.

2. Synthetic fabrics have good heat resistance and thermoplasticity.

3, high strength and elastic recovery ability, has the characteristics of strong and durable, anti-wrinkle and ironing.

4. Good light resistance, comparable to acrylic fabric.

1. Poor hygroscopicity. Polyester fabric has poor hygroscopicity, it will feel sultry when wearing, it is easy to be charged with static electricity, and stained with dust, but it is easy to dry after cleaning, the wet strength is almost unchanged, no deformation, and good wearability.

2. Poor dyeability. Without specific dyeing genes, the dyeing is more difficult and the susceptibility to dyeing is poor, but the color fastness after dyeing is good and it is not easy to fade.

3, easy pilling. One of the synthetic fiber products, after a period of use, pilling will occur.
