Due to the different production methods, acrylic yarn can be divided into many types. So first, let's understand how acrylic yarn is produced. The raw material of acrylic is cheap propylene by-product of petroleum cracking: Since polyacrylonitrile copolymer is heated above 230C, it only undergoes fractional change and does not melt, therefore, it cannot be melt spun like polyester and nylon fiber, and the method of solution spinning is used. Spinning can be used dry method, but also available wet method. Very spinning is suitable for making short fibers, fluffy and soft. Polyacrylonitrile fiber on the raw material and the purity of acrylonitrile requirements are high total content of various impurities should be less than 0.005.

Polymerization of the second monomer mainly with methyl acrylate, also available methyl methacrylate, the purpose is to change the spinnability and fiber feel, softness and elasticity; the third monomer is mainly to improve the dyeing of fibers, generally containing weakly acidic dyeing groups of itaconic acid, containing strong acidic dyeing groups of sodium acrylate sulfonate, sodium methacrylate sulfonate, sodium p-methacrylamide benzene sulfonate, containing basic dyeing groups of - methyl ethylene Pyridine, etc. According to the type, acrylic fabric can be divided into acrylic white yarn, acrylic white yarn, acrylic viscose blended white yarn, acrylic viscose blended white yarn, etc. According to the thickness of yarn, there are many kinds of yarn count specifications, mainly: 8S, 10S, 12S, 16S, 20S, 21S, 30S, 32S, etc. There are many kinds of acrylic fabrics, acrylic pure fabrics, acrylic blended and interwoven fabrics, the main varieties are as follows: 1. Acrylic pure fabrics are made of 100 acrylic fibers.

Such as with 100 hair type acrylic fiber processing of worsted acrylic women's tweed, with loose structure characteristics, its colorful, soft and elastic feel, texture is not loose and not rotten, suitable for the production of low-grade women's clothing. And the use of 100 acrylic bulky yarn as raw materials, can be made of plain or twill organization of acrylic bulky coat tweed, with a feel, warm and easy wool type fabric features, suitable for making spring, autumn and winter coats, casual wear, etc. 2. acrylic blended fabrics refer to wool type or medium-length acrylic and viscose or polyester blended fabrics. Including acrylic / viscose wada tweed, acrylic / viscose women's tweed, acrylic / polyester tweed, etc. Nitrile/viscose wada tweed, also called oriental tweed, is blended with 50 percent each of nitrile and viscose, and has a thick and tight body, strong and durable, with a smooth, soft surface, similar to the style of wool wada tweed, but with poor elasticity and easy wrinkling, suitable for making inexpensive pants.

Nitrile / viscose women's tweed is a blend of 85 acrylic and 15 viscose, mostly woven with crepe tissue, with a slightly hairy surface, bright color, thin body, good durability, poor resilience, suitable for outerwear. The acrylic/polyester tweed is blended with 40 and 60 each of acrylic and polyester, which is processed with plain and twill, so it has the characteristics of flat appearance, firm and iron-free, and the disadvantage is that the sex is poor, so it is mostly used for outerwear, suit and other mid-range clothing.
