Classification of Synthetic Fibers

We are professonal webbing sling manufactuer and supplier. 10 ton flat webbing sling with eyes and 10 ton round lifting slings are bestselling in our store. As you know, our lifting sling are mainly made of synthetic fibers. Here we’d like to tell you the classification of synthetic fibers.

Synthetic fiber is a type of chemical fiber. It uses small-molecule organic compounds as raw materials and is a linear organic polymer compound synthesized through addition polymerization or condensation polymerization, such as polyacrylonitrile, polyester, polyamide, etc. In addition to the general superior properties of chemical fibers, such as high strength, light weight, easy washing and quick drying, good elasticity, and resistance to mildew, different types of synthetic fibers each have certain unique properties.

The synthetic fiber industry began to develop in the early 1940s. The first industrial production was polyamide fiber (nylon), and then acrylic, polyester, etc. were gradually put into industrial production. Synthetic fibers have excellent properties and rich sources of raw materials. With the continuous development of industrial technology, in just a few decades, the world's output of synthetic fibers has approached that of natural fibers, becoming an important raw material for textile fibers. In 1996, the world's synthetic fiber output was 19 million tons, and my country's synthetic fiber output was 2.91 million tons. Correspondingly, the total amount of cotton in the world is 19 million tons.

Classification of synthetic fibers

Fiber materials are mainly used in the textile industry. 

⒈ According to the scope of product use, it can be divided into industrial use and civil use.

⒉ It can be divided into two categories according to the source: one is natural fiber, such as cotton, wool, silk, hemp, etc.; the other is chemical fiber.

Chemical fibers are further divided into man-made fibers and synthetic fibers.

⑴ Man-made fibers are fibers made from cellulose that cannot be woven directly in nature (such as wood, cotton linters) through chemical treatment and mechanical processing, such as rayon, rayon, etc.

⑵ Synthetic fibers are fibers made from petroleum and natural gas as raw materials, through spinning and post-processing of artificially synthesized polymer compounds, such as polyester, etc.

⒊ According to chemical composition, synthetic fibers can be divided into polyamide fibers, polyester fibers, polyacrylonitrile fibers, polypropylene fibers, and polyvinyl alcohol fibers. They are commonly called nylon (or nylon), polyester, acrylic, polypropylene, vinylon, and chlorine.
