The difference between polypropylene fiber and polyacrylonitrile fiber!

The main differences between polypropylene fibers and polyacrylonitrile fibers are their raw materials, properties and applications.

Raw material difference: polypropylene fiber is a kind of bunched monofilament fiber made of high-quality polypropylene by special process. The Polyacrylonitrile fiber, usually called polyacrylonitrile fiber (Polyacrylonitrile or acrylic), is a synthetic fiber spun from more than 85% acrylonitrile and other second and third monomers copolymerized polymer. Acrylic fiber is the trade name of polyacrylonitrile fiber in our country.

Performance differences: Polypropylene fiber has light weight, high strength, good elasticity and wear resistance, as well as excellent electrical insulation and heating properties. With a density of 0.90-0.92 g/cm³, it is the lightest of all chemical fibers and has good dimensional stability and antimicrobial properties. In contrast, polyacrylonitrile fibers have higher elastic modulus, tensile strength and resistance to high temperature and cold. In addition, polyacrylonitrile fiber also has good weather resistance and sun resistance, can be placed outdoors for 18 months to maintain 77% of the original strength, and resistance to chemical agents, especially inorganic acids, bleaching powder, hydrogen peroxide and general organic reagents.

Application: polypropylene fiber because of its lightweight and high strength characteristics, suitable for winter clothing packing or ski wear, mountaineering clothing and other fabrics, is also often used in the manufacture of fishing nets, cables and so on. Polyacrylonitrile fiber is known as "artificial wool" because of its similar performance and weather resistance to wool, widely used in clothing, decoration, industry and other fields, can be blended with wool into wool or woven into blankets, carpets, etc., can also be blended with cotton, artificial fibers and other synthetic fibers, woven into a variety of clothing and indoor supplies.

In summary, although polypropylene fiber and polyacrylonitrile fiber have similar names, there are obvious differences in their raw materials, properties and application fields.
