Analysis of the Properties and Applications of Polypropylene staple fiber!

The diverse characteristics of polypropylene staple fiber

Polypropylene staple fiber, as an important branch of polypropylene fiber, exhibits many unique properties. Its density is extremely low, its texture is light, and it can even float on the water surface. Meanwhile, it features excellent strength and tensile resistance, endowing the material with good durability. In terms of chemical stability, polypropylene staple fibers exhibit certain resistance to acids, alkalis and corrosion. Even after long-term immersion in seawater, their performance remains almost unaffected. In addition, the moisture absorption of this fiber is extremely low, and it hardly absorbs any moisture. This characteristic enables it to maintain stable performance even in a humid environment. More importantly, polypropylene staple fiber is an environmentally friendly and pollution-free material, which conforms to the modern concept of green development.

The wide application of Polypropylene staple fiber

Polypropylene staple fiber has been widely applied in multiple fields due to its outstanding performance. It is often used to make needled carpets and is favored by the market for its wear-resistant and easy-to-clean features. In terms of automotive interiors, the soft touch and excellent anti-fouling performance of polypropylene staple fibers make them an ideal choice. Meanwhile, it is also an important raw material for non-woven fabrics, ropes and decorative materials. In the field of medical and health care, the environmental friendliness and non-toxicity of Polypropylene staple fibers have been fully exploited and they are widely used in the manufacturing of various medical supplies.

General knowledge about short fibers

"Short fiber", also known as cut fiber, is obtained by cutting or pulling the long fiber bundles of chemical fibers to make their length comparable to that of natural fibers. In addition to chemical fibers, natural fibers such as whiskers and asbestos can also be regarded as short fibers. The length of short fibers usually ranges from 35 to 150 millimeters. According to the specifications of natural fibers, they can be further classified into cotton type, wool type, carpet type and medium-long type, etc. These short fibers can be spun alone or blended with natural fibers or other chemical fibers in different proportions to produce products such as yarns, fabrics and felts.
