Exploring Polyester Staple Fiber: Performing Well in Non-woven, Spinning and Filling Fields

Polyester Staple Fiber (PSF for short) is a kind of chemical fiber, which is obtained by spinning polyethylene terephthalate (PET) into tow and then cutting it. According to different uses, polyester staple fiber can be mainly divided into three categories: polyester staple fiber for non - woven fabrics, polyester staple fiber for spinning and polyester staple fiber for filling. The specific introduction is as follows:

Usually, the special specification for hydroentangling of 1.56dtex*38mm is adopted, which has good hydrophilicity. It is widely used in wet wipes, medical and other fields, such as medical gauze, disinfection wipes, etc. Its hydrophilicity can better absorb liquid, and it also has certain strength and wear - resistance to meet the use requirements. In the engineering field, geotextiles, leather - base fabrics, asphalt felt base fabrics, etc. also use this kind of polyester staple fiber, which can enhance the strength and stability of materials and adapt to the needs of different engineering environments.

This is one of the most important downstream fields of polyester staple fiber. Specifications such as semi - dull natural white 1.56dtex38mm and 1.33dtex38mm are commonly used. It can be spun alone to make pure polyester yarn, or blended with cotton, viscose staple fiber, etc. to make polyester - cotton yarn, polyester - viscose yarn, etc., and then used for weaving to produce various clothing fabrics, home - textile fabrics, etc. In the thread - making aspect, the special specification for sewing thread of bright or semi - dull 1.33*38mm is mainly used to make stranded thread, which is used for sewing clothing, luggage, etc. It is required to have high strength and wear - resistance to ensure that the sewing thread does not break during use.

Generally, 3D - 15D hollow fibers, low - melting - point fibers, etc. are used, and they are often made into products such as spray - bonded cotton, non - bonded cotton, pearl cotton, etc., which are used in home - textile filling and clothing filling fields, such as pillows, quilts, cotton - padded clothes, etc. The three - dimensional hollow structure of hollow fibers can lock more air, thus improving the heat - preservation performance, and at the same time, making it have a light and fluffy hand - feel. The low - melting - point fibers can be bonded with other fibers by heating and melting, so that the filling material has certain formability and stability.
