PP staple fiber belongs to an industrial production process of polypropylene fiber, and its name is the manufacturing process of fine denier PP staple fiber.

The current cotton spinning industry is in a downturn, mainly due to the aging of the product structure and the shortage of cotton. As the saying goes, "The clever woman is difficult to do without rice." In the absence of raw materials or serious shortage of raw materials, the development of the cotton spinning industry depends on national policies; the second is to find new sources of raw materials. That is to find the best alternative fiber for cotton fiber.

Practice has gradually made people realize that when the fineness of PP staple fiber is less than 1.11 dtex, the waxy texture of synthetic fiber is completely eliminated. Its appearance and feel are not only different from high-quality combed cotton, but also have a better core than cotton. The suction effect is one of the ideal replacements to solve the current contradiction between supply and demand of cotton fiber.

PP staple fiber is an inexpensive fiber, and its light weight is light (see table below). Equal weight materials can produce more fabrics, which is beneficial to reduce costs.
