Wuhan Handern Organic Polymer Fiber
Kevlar fiber was industrially produced by DuPont of the United States in 1972. It is a variety of aromatic polyacid (Aramid) fiber. It has super rigid molecular chain and super high modulus. After many experiments, good dimensions are produced by the wet method, and the tensile modulus of the fiber is more than 50GPa (353eN/dtex), which is two and a half times higher than that of glass fiber. Under the same quality, it is more rigid than glass fiber. In 1970, DuPont Blades invented the dry jet-wet spinning process, which increased the fiber strength by two times and the silk speed by four times. Since then, DuPont started the industrialization of aromatic polyamide fiber, which was later commercialized as Frau. The difference with general energy amines is that most of the polymer main chain is aliphatic (anti) group and cycloaliphatic (anti) group. Aromatic fibers include Kewa (polyterephthalene terephthalate fiber) from DuPont, NOmnex (polymetaphenylene diamine fiber), Teijin Connor of Japan Conex (polyisophthalic acid isophthalic acid), Technora (polypara-xylenediamine) and Akzo Twaron (polyterephthalic acid
Three-dimensional). The two new dimensions and muscle fibers developed in my country in the early 1980s are consistent. Named as Aramid 1414 and Aramid 14, collectively referred to as Aramid fiber. www.handern.com Meltblown non-woven equipment
