Polyester staple fiber is an important raw material for chemical production, which is widely used in textiles, clothing, non-woven fabrics and other fields. This article will detail the nature and use of polyester staple fiber.

1. the properties of polyester staple fiber

1. Physical properties
polyester staple fiber is a synthetic fiber with good physical properties. Its appearance is white or slightly yellow cylindrical short fiber, with high strength and elasticity, and good wear resistance. The density of polyester staple fiber is larger than that of natural fiber and has better shape retention.

2. chemical properties
polyester staple fiber has good chemical stability, can resist the erosion of acid, alkali, oxidant and other chemical substances. At the same time, polyester staple fiber has good light resistance and can be exposed to the sun for a long time without discoloration.

2. the use of polyester staple fiber

1.
in the textile field Polyester staple fiber has a wide range of applications in the textile field, mainly used in the production of various textiles. Because of its good strength and elasticity, it is often used to make sportswear, outdoor clothing and other clothing that requires high durability. In addition, polyester staple fiber can also be blended with other natural fibers or synthetic fibers to improve the performance and appearance of textiles.

2.
in the field of non-woven fabrics Polyester staple fiber is also widely used in the field of non-woven fabrics. Non-woven fabric is a kind of non-woven material, which is breathable, soft and easy to clean, and is widely used in health, medical, home and other fields. Polyester staple fiber is one of the main raw materials for non-woven fabric production, which can improve the strength and durability of non-woven fabrics.

3. Other fields
In addition to the field of textiles and non-woven fabrics, polyester staple fibers can also be used to produce ropes, filters, fillers, etc. At the same time, polyester staple fiber can also be used as a reinforcing material to improve the performance of plastics, rubber and other materials.

In short, polyester staple fiber as an important chemical production raw materials, has a wide range of uses. In the future development, with the continuous progress of technology and the continuous expansion of application fields, the use of polyester staple fiber will be more extensive.
