Acrylic yarn is a kind of chemical fiber, its performance is very similar to wool, so it is called "synthetic wool". Molecular structure: Acrylic fiber is unique in the internal structure of Oita, showing an irregular spiral conformation, and there is no strict crystallization zone, but there are high-order and low-order arrangements. Due to this structure, acrylic fiber has good thermal elasticity (processable bulked yarn), acrylic fiber has a low density, which is smaller than wool, and the fabric has good warmth retention. It has good elasticity, second only to polyester, about 2 times higher than nylon, and has good shape retention.
The light resistance of acrylic fiber is the best one year of outdoor exposure among all synthetic fibers, and the strength is only reduced by 20%. Because acrylic yarn has good bulkiness and soft feel, it is often used to make wool, carpets, etc.; because of its good weather resistance, mildew and moth resistance, it can also be spun purely or blended with natural fibers, and is widely used in various tarpaulins. , Decoration, and industrial fields, curtains and other industries; because of its good warmth retention, it is also used to make clothing, plush, artificial fur, etc.
Acrylic yarn is characterized by good sunlight and weather resistance (ranking first), poor moisture absorption, and difficult dyeing.
Pure acrylonitrile fiber has a compact internal structure and poor wearability. Therefore, the second and third monomers are added to improve its performance. The second monomer improves the elasticity and feel, and the third monomer improves the dyeability.
Uses: Mainly used for civilian use. It can be pure or blended to make a variety of wool, wool, blankets, sportswear; also: artificial fur, plush, bulked yarn, hose, parasol cloth, etc.
