Due to different production methods, acrylic yarn can be divided into many types. So first of all, let&39;s take a look at the production method of acrylic yarn. The raw material of acrylic fiber is the cheap propylene by-product of petroleum cracking: because the polyacrylonitrile copolymer is heated to above 230C, it only undergoes decomposition and does not melt. Therefore, it cannot be melt-spun like polyester and nylon fibers. Method of solution spinning. Spinning can be dry or wet. Very suitable for short fiber spinning, fluffy and soft. The polyacrylonitrile fiber has higher requirements on the purity of the raw material bisacene nitrile, and the total content of various impurities should be lower than 0.005. The two monomers of polymerization are mainly methyl acrylate, and methyl methacrylate can also be used, the purpose is to change the spinnability and the feel, softness and elasticity of the fibers; the third monomer is mainly to improve the dyeability of the fibers, generally containing Itaconic acid with weak acid dyeing group, sodium propylene sulfonate with strong acid dyeing group, sodium methacrylic acid sulfonate, sodium p-methacrylamide benzene sulfonate, - methyl vinyl with basic dyeing group Pyridine etc. According to the type of acrylic fabric, it 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 the yarn, there are various yarn count specifications, mainly:8S, 10S, 12S, 16S, 20S, 21S, 30S, 32S, etc.

　　There are many types of acrylic fabrics, including pure acrylic fabrics, and acrylic blended and interwoven fabrics. The main varieties are as follows:
　　1. The acrylic pure fabric is made of 100% acrylic fiber. For example, the worsted acrylic women&39;s woolen fabric processed with 100 wool-type acrylic fiber has the characteristics of loose structure, bright color, soft and elastic feel, and the texture is neither loose nor rotten. It is suitable for making middle and low-grade women&39;s clothing. And using 100 acrylic bulked yarn as raw material, plain or twill weave acrylic bulked coat can be made, which has the characteristics of hand-feeling, warm and relaxed wool fabric, suitable for making spring, autumn and winter coats, casual clothes, etc.
    
　　2. Acrylic blended fabrics refer to fabrics blended with wool or mid-length acrylic and viscose or polyester. Including Nitrile/Viscose Gabardine, Nitrile/Viscose Ladies, Nitrile/Polyester Tweed, etc. Nitrile/viscose gabardine, also known as oriental wool, is blended with nitrile and viscose each in a proportion of50. It has a thick and tight body, strong and durable, and a smooth, soft, wool-like gabardine-like style, but it has poor elasticity and is easy to use. Wrinkled, suitable for making cheap trousers. The nitrile/viscose women&39;s woolen is made of 85% acrylic and 15% viscose, and is mostly woven with crepe. The surface is slightly fluffed, the color is bright, the body is light and thin, the durability is good, and the resilience is poor. It is suitable for outerwear. Nitrile/polyester tweed is a blend of nitrile and polyester with 40 and 60 respectively. Because it is mostly processed with plain weave and twill weave, it has the characteristics of flat appearance, firmness and no ironing. Its disadvantage is that it has poor performance, so it is mostly used for Production of mid-range clothing such as outerwear and suits.
