How Many Types of Polyester Staple Fiber Have?

According to the spinning process technology, the products are divided into solid recycled polyester staple fiber and hollow recycled polyester staple fiber.

Among them, solid recycled polyester staple fiber is divided into the following four categories:

a. Cotton type: The linear density is 1.5-2.1dtex. It is divided into two types: high-tenacity cotton type and normal cotton type. High-tenacity cotton type varies according to its application.

b. Medium length type: line density is 2.2-3.2dtex.

c. Wool type: divided into fine denier wool type and high denier wool type. The density of fine denier wool fiber is 3.3-6.0dtex. The higher denier fiber density is 6.1-27.78dtex.

d. Polyester staple fiber for filling: linear density is 3.33dtex-27.28 dtex.

Hollow recycled polyester staple fiber is divided into two dimensional hollow polyester staple fiber and three dimensional hollow polyester staple fiber.

The above fibers can be divided into non-sliconized and siliconized types according to finishing process.
