Polyester filament is a filament with a length of more than one kilometer, and the filament is wound into a ball.
Polyester filament is divided into three types: POY, DTY and FDY.
DTY – Draw texturing yarn, the fibers are crimped.
POY and FDY fibers are straight, and the strength of FDY is better than that of POY.
The production cost of FDY is low, and the quality of the finished product is stable, the yarn breakage is less, and the dyeing uniformity is good.
Characteristics of polyester filament thread:
High strength, good heat resistance, elasticity, wear resistance, low moisture regain, good insulation performance. Poor staining.
Polyester filament thread has a wide range of applications, mainly divided into civil and industrial use:
Polyester is used as a clothing fiber, and its fabrics are wrinkle-free and iron-free after washing. Polyester is often blended or interwoven with various fibers, such as cotton polyester, wool polyester, etc., and is widely used in various clothing and decorative materials.
Polyester can be used for conveyor belts, tents, canvas, cables, fishing nets, etc. in industry, especially polyester cords used for tires, which are close to nylon in performance.
Polyester can also be used for electrical insulating materials, acid-resistant filter cloth, medical industrial cloth, etc. Synthetic fibers have been widely used in various fields of the national economy due to their high strength, wear resistance, acid resistance, alkali resistance, high temperature resistance, light weight, warmth, good electrical insulation and no fear of mildew.
