What is the difference between acrylic fiber and Huimin Taili polyacrylonitrile fiber?

Acrylic fiber and Huimin Taili polyacrylonitrile fiber are actually different names for the same material, and there is no essential difference between them. The following is a detailed explanation of acrylic fiber (polyacrylonitrile fiber) :

Definition and composition

Acrylic: Also known as Huimin Taili polyacrylonitrile fiber or artificial wool fiber, is an important synthetic fiber. It is spun from acrylonitrile monomer after a polymerization reaction.

Polyacrylonitrile fiber: from the chemical composition point of view, it is the fiber formed after the polymerization of acrylonitrile, which is completely consistent with the acrylic fiber.

Ii. Characteristics

Physical properties: acrylic fiber (polyacrylonitrile fiber) fluffy texture, soft feel, low density, good warmth, high resilience. The softening temperature of the fiber is between 190230℃, the thermal decomposition temperature is 200250℃, and the melting point is 320℃.

Chemical properties: acrylic fiber (polyacrylonitrile fiber) has excellent light resistance, weather resistance, moth resistance, radiation resistance, biodegradation resistance and good dyeing property. The surface of the fiber can be partially hydrolyzed, so that the cyanide group (-CN) on the surface of the fiber is converted to the carboxyl group (-COOH). Due to its hydrophobicity and insulation, acrylic fibers (polyacrylonitrile fibers) are prone to static electricity.

3. Application fields

Clothing field: acrylic (polyacrylonitrile fiber) can be pure spun or blended with natural fibers, and its textiles are widely used in the production of clothing, such as wool, knitted fabrics (pure spun or blended with wool) and woven fabrics, especially suitable for indoor decorative fabrics, such as curtains. In addition, acrylic fiber (polyacrylonitrile fiber) is also used to make warm clothing, sportswear and so on.

Industry: Acrylic fiber (polyacrylonitrile fiber) is also used in outdoor fabrics, cement reinforcement materials, lead battery plate reinforcement materials, filter materials, pre-oxidized fibers and carbon fibers and other fields. In addition, polyacrylonitrile engineering fibers are also used in construction projects with higher requirements such as cracking, impact resistance, wear resistance, earthquake resistance, such as bridge decks, bridge piers, road surfaces, airport runways, apron, military protection projects, port terminals, dam panels, diversion tunnels, floodgates, pier piers, etc. Polyacrylonitrile hollow fiber can be used as the material of artificial kidney dialyzer.

4. Production process

Acrylic fiber (polyacrylonitrile fiber) is usually produced by wet spinning or dry spinning. In the spinning process, the spinning solution is generally a polyacrylonitrile polymer with an average molecular weight of 53,000 to 106000. The polymerized slurry is sent to the spinning machine for spinning after steps such as demonomer, defoaming, temperature regulation and filtration. After spinning is completed, it is also necessary to carry out post-treatment, such as oiling, drying, crimping, steam heat setting and other steps, and finally obtain acrylic fiber (polyacrylonitrile fiber) products.

To sum up, acrylic and Huimin Taili polyacrylonitrile fibers are the same material, with similar physical and chemical properties, as well as a wide range of applications. In practical applications, suitable fiber types can be selected according to specific needs.
