The so-called ultra-short polypropylene staple fiber generally refers to any polypropylene staple fiber with a cut length of less than 20 mm. It has a high breaking strength, a low elongation at break, a low shrinkage in boiling water or hot air, and a shorter cut length than conventional polypropylene. Fiber, high dispersion in the medium, antistatic properties. Its main varieties are polypropylene (PP), polyethylene (PE) / PP composite fiber PP / PET composite fiber and so on.

In the 1980s, a few developed countries in the United States and Europe successfully developed ultra-short polypropylene staple fiber and carried out extensive promotion and application, forming a certain production capacity. However, the application and development of polypropylene ultra-short fibers lags behind in China. Until the late 1990s, as China's national economy continued to develop rapidly for many years, foreign ultra-short polypropylene staple fiber gradually entered the domestic market, and their product characteristics and performance were gradually The domestic industry understands and understands and has begun to apply to industries such as papermaking and construction.

Ultra-short polypropylene staple fiber is one of the indispensable species in ultra-short fibers. It is characterized by its low density, high strength, strong wicking effect, air permeability, water permeability, non-toxicity, low melting point, water repellency and oil absorption. Used in papermaking, construction, non-woven and other industries.
