Acrilonitrile is the main main raw material for the manufacture of, Acetylene + Hydrogen cyanide --> Acrilonitrile, Ethylene--Air Oxidation--> Ethylene oxide + HCN--> Ethylene cyanahydrin--Dehydration at 300 deg C (catalyst)--> Acrylonitrile. Quartz, however, is crystalline (rigid, highly ordered atomic structure) and is 99% or more SiO 2.If SiO 2 is heated above 1200°C/2192°F then cooled ambiently, it crystallizes and becomes quartz. Polyester padding is preferred for sportswear. It has a good resistance to mineral acids. The spinneret is submerged in a chemical bath that causes the fiber to precipitate, and then solidify, as it emerges. It was the research at Du-pont that produced the first acrylic fiber initially called “ Fiber A “ and subsequently named “ Orlon “ . The process gets its name from this "wet" bath. In wet spinning, the spinning solution is extruded into a liquid coagulating bath to form filaments, which are drawn, dried, and processed. It is available in staple, tow, spinning top. Spinning is followed by a series of treatments whose purpose is to impart the necessary physical-mechanical characteristics to the fiber. Acrylic, rayon, aramid, modacrylic, and spandex are produced via this process. It is generally used for produce suitable sweater because it is like wool. Textile-grade glass fibers are made from silica (SiO 2) sand, which melts at 1720°C/3128°F.SiO 2 is also the basic element in quartz, a naturally occurring rock. Acrylic has a warm and dry hand like wool. Acrylic fibres are synthetic fibres based on linear polymer PAN; the building block of this polymer is a monomer with the formula CH 2 CHCN.
