Polyester is an important variety of synthetic fibers and is the commercial name for polyester fiber in China.
Polyester filament is made using polyester to create long filaments. Polyester filament is a fiber with lengths exceeding kilometers, wound into bundles. Fabrics woven from polyester filaments are glossy, have a smooth feel, and resemble nylon fabrics.
Polyester has a wide range of uses, extensively in the production of clothing and industrial products. Flame-retardant polyester, due to its flame-retardant properties, is widely applied. Besides playing an irreplaceable role in industrial textiles, interior decorations for buildings, and decorations for transportation, it also plays a significant role in the field of protective clothing. According to the national standards for flame-retardant protective clothing, sectors such as metallurgy, forestry, chemical industry, petroleum, and firefighting should use flame-retardant protective clothing. In China, the number of people who should be using flame-retardant protective clothing exceeds one million, indicating a huge market potential for flame-retardant protective clothing. Besides pure flame-retardant polyester, multifunctional series products featuring flame-retardant, waterproof, oil-repellent, and anti-static properties can also be produced according to users' special requirements. For instance, treating flame-retardant polyester fabrics with waterproof and oil-repellent finishes can enhance the functionality of flame-retardant garments; interweaving flame-retardant polyester with conductive fibers can produce anti-static flame-retardant fabrics; blending flame-retardant fibers with high-performance fibers can create high-performance flame-retardant fabrics; blending flame-retardant fibers with cotton, viscose, and other fibers can improve the comfort of protective clothing while reducing secondary burns.
According to the production process, polyester filament can be classified into: 1. Primary filament: undrawn filament (conventional spinning) (UDY), semi-oriented filament (medium-speed spinning) (MOY), pre-oriented filament (high-speed spinning) (POY), highly oriented filament (super-high-speed spinning) (HOY). 2. Drawn filament: drawn filament (low-speed drawn filament) (DY), fully drawn yarn (spinning and drawing in one-step) (FDY), fully oriented yarn (one-step spinning) (FOY). 3. Textured filament: conventional textured yarn (TY), draw-textured yarn (DTY), air-textured yarn (ATY).
According to usage, it is mainly divided into civil and industrial use. For more info, feel free to contact JINGZE polyester sewing thread china supplier.
