In life, polyester staple fiber products are mainly used in the cotton spinning industry. They are spun separately or blended with cotton, viscose, hemp, wool, vinylon, etc. The yarns obtained are mainly used for garment weaving, and can also be used for home decoration fabrics. Packaging cloth, filling and warming materials.

The main characteristics of polyester staple fiber are wear resistance and water absorption, which are widely used in life and industry.

Heat resistance: It can be used at -70 ° C to 170 ° C, which is the best in heat resistance and thermal stability of synthetic fibers.

Elasticity: The elasticity of polyester is close to wool, the wrinkle resistance is higher than other fibers, the fabric is not wrinkled, and the shape retention is good.

Abrasion resistance: Polyester's wear resistance is second only to nylon, ranking second in synthetic fiber. The use of polyester filaments is polyester as a fiber for clothing, and the fabric has a wrinkle-free and non-ironing effect after washing.

The classification of polyester staple fibers is also very diverse. Generally speaking, polyester staple fibers on the market today are classified into three categories: large chemical fiber, medium chemical fiber and small chemical fiber.

Large-scale chemical fiber: Direct spinning with PET sheet spinning or molten short fibers. The color is good, the batch number is large, firm and stable, less defects, and good spinnability. In chemical fiber: Spinning with foreign PET chips or PET back material. Price quality is between size (some major spinning mills are used to increase competitiveness

Small chemical fiber: PET back spinning. Unbalanced price and quality, suitable for exporting some quality requirements are not higher than the market and regions (such as fillers, etc.).

In general, the sliced spun fiber is substantially free of defects, the fiber thickness, color, and physical index are uniform, the surface is smooth, and the hand feels smoother.
