Acrylic yarn is an important textile fabric, known as "synthetic wool".
　　Acrylic yarn classification:
　　According to the type of acrylic fabric, it can be divided into acrylic white yarn, acrylic viscose blended white yarn, acrylic cotton blended white yarn, etc.
　　According to the thickness of the yarn, there are various yarn count specifications, mainly: 5S, 8S, 10S, 12S, 16S, 20S, 21S, 30S, 32S, etc.
　　Acrylic fiber is a kind of material with better tactility, bright and bright color on the outside, and its cost is relatively low, far less than wool and pure cotton, but acrylic fiber has good recovery performance, is not easy to deform, and is much stronger than pure cotton. Therefore, acrylic fibers are often used to make carpets. Acrylic fiber looks like wool, so it is called "artificial wool". It feels very smooth to the touch, and has the characteristics of softness, bulkiness and bright color. Its advantages of light resistance, Kangjun ability and insect resistance are also particularly outstanding. According to different purposes, it can also be spun pure or blended with fibers. Various decoration, and industrial fields. Acrylic fibers can also be used to make wool, and polyene acrylic fibers and wool can be blended to make wool, or woven into blankets, carpets, etc., and can also be blended with cotton, rayon, and other synthetic fibers. The bulked tops processed from polyacrylonitrile fibers can be spun pure, or blended with viscose fibers and wool, to various specifications of medium-thick and fine-pile "cashmee". The performance of the polyacrylonitrile fiber is similar to that of wool, with good elasticity. When the elongation is20, the rebound rate can still be maintained at 65. It is fluffy, curly and soft, and its warmth retention is 15 higher than that of wool. It is called synthetic wool. The strength is 22.1~48.5cN/tex, 1~2.5 times higher than wool. Acrylic fiber has excellent light fastness, and its strength is only reduced by 20% in hot summer, so it can be used for curtains, curtains, tarpaulins, gun clothing, etc. It is resistant to acids, oxidants and general organic solvents, but poor alkali resistance. Fiber softening temperature 190 ~ 230 ℃.
 
　　Solid acrylic yarn 21, 10, 16, 32, 45, single yarn, acrylic fiber is called artificial wool. It has the advantages of softness, bulkiness, easy dyeing, bright color, light resistance, and no fear of insects. According to the requirements of different uses, it can be spun purely or blended with fibers. Its textiles are widely used in clothing, decoration, industry and other fields such as production Shirts, spring and autumn coats, sweatshirts, all kinds of blankets, etc.; in addition, a small part is also used in the production of awning fabrics, sails and filter fabrics, etc.
