As a Polyester Cotton Fabric Wholesale, share with you. The main feature of polyester-cotton blended yarn is its high breaking strength, which is generally more than 40% higher than that of cotton of the same specification; it has good wear resistance and is generally 1 times higher than that of cotton of the same specification; the shrinkage rate is small, and the shrinkage rate is only about 0.5%, which is suitable Sewing chemical fiber fabrics and anti-wrinkle high-grade cotton fabrics, with flat stitches; good heat resistance, suitable for high-speed sewing machines of 3000-4000r/min, ironing temperature around 160℃; good flexibility and elasticity, suitable for sewing high-grade chemical fibers fabric.

Polyester filament is made of polyester filament. Polyester is an important variety of synthetic fibers, and it is the trade name of polyester fiber in my country. It is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation reactions ——Polyethylene terephthalate (PET), a fiber made by spinning and post-processing. The so-called polyester filament is a filament with a length of more than one kilometer, and the filament is wound into a group.

According to the production method:

1. Primary silk: undrawn silk (conventional spinning) (UDY), semi-prefetched

Oriented yarn (medium-speed spinning) (MOY), pre-oriented yarn (high-speed spinning) (POY), highly oriented yarn (ultra-high-speed spinning) (HOY)

2. Drawing filament: drawn filament (low-speed drawing filament) (DY), fully drawn filament (spinning and drawing one-step method) (FDY), full-drawing filament (spinning one-step method) (FOY)

3. Textured yarn: conventional textured yarn (TY), stretched textured yarn (DTY), air textured yarn (ATY).

By purpose

Mainly divided into civil and industrial use

Polyester is widely used in the manufacture of clothing and industrial products. Due to its flame retardancy, flame-retardant polyester has a wide range of applications. In addition to its irreplaceable role in industrial textiles, architectural interiors, and interior decoration of vehicles, it also plays a lot of roles in the field of protective clothing. According to the national standards for flame-retardant protective clothing, metallurgy, forestry, chemical, petroleum, and fire protection departments should use flame-retardant protective clothing. The number of people who should use flame-retardant protective clothing in China is more than one million, and the market potential of flame-retardant protective clothing is huge. In addition to pure flame-retardant polyester, it can produce flame-retardant, waterproof, oil-repellent, anti-static and other multifunctional products according to the special requirements of users. For example, waterproof and oil-repellent finishing of flame-retardant polyester fabric can improve the functionality of flame-retardant clothing; use flame-retardant polyester and conductive fiber to produce antistatic flame-retardant fabric; use flame-retardant fiber and high-performance fiber for blending and interweaving , Can produce high-performance flame-retardant fabrics; use flame-retardant fiber blended with cotton, viscose and other fibers to improve the comfort of protective clothing and reduce secondary burns.
