Fiber is divided into chemical fiber and synthetic fiber two kinds, so how to distinguish?

Chemical fiber refers to man-made fibers in addition to natural fibers. Chemical fibers can be divided into regenerated fibers and synthetic fibers. Recycled fibers are chemical fibers made from natural products (cellulose, protein, etc.) through the spinning process.

Synthetic fibers are chemical fibers made of polymers synthesized from organic monomers and other chemical raw materials. Commonly used synthetic fibers are polyester, nylon, acrylic, spandex, polypropylene, Vinylon and so on. Among them, the output of polyester and nylon accounts for more than 85% of the total output of chemical fibers, which are widely used in various fields such as clothing, decorative materials and industrial fabrics. The total output of acrylic fiber, spandex, polypropylene, vinylon and carbon fiber, arfiber, ultra-high molecular weight polyethylene fiber, etc. accounts for less than 15% of the total output of chemical fiber, which is a small variety in the large family of chemical fiber, and its application fields are mostly polyester, nylon performance is less applicable, and there are special requirements for a certain performance. Polypropylene fiber, that is, the trade name of polypropylene fiber, is a synthetic fiber made of propylene, a by-product of petroleum refining.

Polypropylene has the characteristics of environmental protection, light weight, high strength, good acid and alkali resistance, good heat preservation, no water absorption, poor dyeing, poor heat resistance, poor aging resistance and so on.
