Acrylic fiber was invented in 1950. It has a round or DuPont appearance, a smooth surface, and is not easy to absorb water, resist acid, Alkali, and sunlight. Good clothing and wool feel similar but heat preservation and the finished surface easily pilling, commonly known as polyacrylonitrile fiber, polyacrylonitrile fiber is our country's trade name. Acrylic is just a kind of acrylic fiber, acrylic fiber including Raschel, acrylic, etc.. At least 85% of the list of synthetic polymers fiber.

Characteristics
1. High-performance pure acrylonitrile, has a strong chemical corrosion resistance. The basic principles of its chemical corrosion resistance: 1. Chemical Properties: contains very little residual impurities, such as organic solvents or acidic compounds, and then high-temperature long-term use will not affect its quality. 2. Structural Characteristics: It is the choice to resist chemical corrosion for a long time because of its fine, dense, and ductile structure. Even if long-term in the case of chemical corrosion and high temperature, can effectively prevent the infiltration of harmful chemicals. Second, thermal stability: Acrylic Fiber compared with the general acrylonitrile, with higher strength of heat resistance. Chemical Resistance: Chemical Resistance is much higher than that of polyester or other acrylonitrile fibers. It has Alkali resistance and corrosion resistance to SO2, O2, O3, and other gases. Shrinkage: At temperatures of 220 degrees centigrade there is al no shrinkage of its own, but some thermal shrinkage may result from deviations in the manufacturing process, such as weaving, weaving, and non-woven fabrics, heat treatment is recommended. In terms of application, acrylic fiber can be spun into acrylic yarn or blended with wool into wool-like yarn, and further woven into man-made sweaters or carpets. As acrylic fiber downstream yarn factories gradually moved to the Chinese mainland, so that acrylic cotton to export-oriented, quite dependent on the demand of the mainland yarn factory. The main production areas are Japan, the United States, South Korea and Taiwan, China.
