Usually, in daily life, when we buy polyacrylonitrile fiber for the merchant, it is commonly known as acrylic fiber. The acrylic synthetic fiber contains a polyacrylonitrile or an acrylonitrile copolymer having an acrylonitrile content of more than 85% .
Acrylic fiber is unique in its internal macrostructure, has an irregular spiral conformation, and has no strict crystallization zone, but has a high order and a low order.
Because of this structure, the acrylic fiber has good thermoelasticity (processable bulky yarn), the acrylic fiber has a small density, is smaller than wool, and the fabric has good warmth retention.
Good sunlight resistance and weather resistance (first place), poor moisture absorption and difficult dyeing.
How to improve its performance (ie methods to improve the shortcomings)
Pure acrylonitrile fiber, due to its tight internal structure and poor handling properties, improves its properties by adding a second, third monomer, second monomer improves, elasticity and hand, and the third monomer improves dyeability.
The acrylic fiber has a squeaking sound when burned, and the smell is like a grilled fish and spicy.
