Acrylic yarn is a kind of chemical fiber, and its performance is very similar to wool, so it is called "synthetic wool". Molecular structure: Acrylic fiber is very unique in its internal large substructure, showing an irregular helical conformation, and there is no strict crystalline region, but there are high-order and low-order arrangements. Because of this structure, acrylic fiber has good thermal elasticity (bulked yarn can be processed), the density of acrylic fiber is small, smaller than wool, and the fabric has good thermal insulation. The elasticity is better, second only to polyester, about 2 times higher than nylon, and has better shape retention.

　　1. The performance of the acrylic fabric is very similar to wool, but its elasticity is much better than that of wool. Under the condition of elongation of 20, the rebound rate can be maintained at about 65.

　　2. Acrylic fabrics are better than wool in terms of warmth retention. Acrylic fibers are fluffy and curly in appearance and feel very soft to the touch, so their warmth retention is much better than wool fabrics. There was a saying about "synthetic wool".

　　3. The strength of the acrylic fabric is higher than that of wool. At present, the strength of the acrylic fiber is about 22.1-48.5cN/dtex, while wool is about 1 to 2.5 times lower than that of acrylic fabric.

　　4. Acrylic fiber has strong resistance to sunlight, that is, excellent light resistance. If you expose acrylic fiber to the sun, there will be no problem at all. Experiments have shown that items made of acrylic fabric are placed in the sun. After a year of exposure to the sun, its intensity has only dropped by less than 20, which shows how practical it is.

　　5. Products made of acrylic fabrics are generally not afraid of acid attack and have excellent resistance to acid, oxidants, and general solvents.

　　However, acrylic fabrics also have certain shortcomings, that is, the alkali resistance is poor. If you use alkaline cleaning products when washing, you should pay attention. At the same time, the relatively high temperature will also have a greater impact on the acrylic fiber fabric. Under the high temperature of about 190 to 230 degrees, the phenomenon of acrylic fiber will appear. In addition, the hygroscopicity of acrylic fabrics is also relatively poor.
