Acrylic fiber is one of the three major varieties of synthetic fiber, and its output ranks third after polyester and nylon. It is soft, light, warm, corrosion-resistant, light-resistant and wool-like short fiber. The density is smaller than wool. It is called artificial wool.

Acrylic fiber is fluffy, curly and soft, with good elasticity, but the residual deformation after repeated stretching is large, so the cuff and neckline of acrylic fabric are easy to deform. Acrylic fiber is more than 10% lighter than wool, but its strength is more than 2 times; The resilience of wool is not as good as that of wool when the elongation is small, and the resilience of wool is better than that of nylon during wearing.
