What is the difference between polyester FDY silk and viscose FDY silk?

polyester FDY silk and viscose FDY silk are significantly different in several ways, and the following is a detailed comparison of the two fibers:

First, raw materials and production methods

polyester FDY silk:

Raw material: Polyester chip (PET) as the main raw material.

Production method: Using one step process of spinning and drawing, through low speed spinning, high speed drawing and winding production.

Viscose FDY silk:

Raw material: Artificial cellulose fiber produced by solution spinning.

Production method: Its production method is different from that of polyester FDY silk, but it is also made by a specific spinning and drawing process.

2. Physical properties

polyester FDY silk:

High strength: high breaking strength and elongation at break.

Good elasticity: high elastic recovery rate, not easy to deformation.

Good heat resistance and thermal stability: it can maintain stable performance at higher temperatures.

Good wear resistance: excellent wear resistance, suitable for a variety of friction environments.

Good light resistance: good light resistance, not easy to fade.

Viscose FDY silk:

Strong hygroscopic: It is one of the strongest hygroscopic fibers in ordinary chemical fibers.

Good dyeing: easy to dye and bright colors.

Poor elasticity: Compared with polyester, its elasticity is poor and easy to deform.

Poor heat and wear resistance: the performance is susceptible to high temperature and friction environments.

Third, appearance and feel

polyester FDY silk:

Appearance: high gloss, strong reflection.

Hand feel: The hand feel is hard, but the clarity is good.

Viscose FDY silk:

Appearance: The gloss is relatively soft, not as bright as polyester FDY silk.

Feel: soft and comfortable, good wearing.

4. Application field

polyester FDY silk:

Mainly used in clothing, home textiles and industrial textiles and other fields. Such as the production of imitation silk fabrics, sportswear, outdoor clothing and ropes, fishing nets and so on.

Viscose FDY silk:

Because of its strong moisture absorption, good dyeing and other characteristics, it is mainly used in the production of underwear, shirts, skirts and other clothing that needs comfort and softness. At the same time, it is also used to make curtains, bedding and other home textile products.

In summary, polyester FDY silk and viscose FDY silk have significant differences in raw materials, production methods, physical properties, appearance and feel, as well as application fields. Which fiber to choose depends on the specific application needs and consumer preferences.
