Background
Chemical fiber refers to fiber made from natural or synthetic high molecular substances. Depending on the source of the raw material, the fiber can be classified into artificial fiber using a natural polymer as the raw material and synthetic fiber using a synthetic polymer as the raw material.
Chemical fibers are generally prepared by first forming a natural or synthetic polymeric or inorganic substance into a spinning melt or solution, then filtering, metering, extruding from a spinneret (plate) into a liquid stream, and then coagulating to form the fiber. The fiber is called as nascent fiber, has poor mechanical property, and can meet the requirements of textile processing and use only through a series of post-processing procedures. Post-processing is directed primarily to stretching and heat-setting the fiber to improve the mechanical properties and dimensional stability of the fiber. Stretching is to orient the macromolecules or structural units in the as-spun fibers along the fiber axis; heat-setting is primarily a relaxation of internal stresses in the fiber. The post-processing of the wet-spun fibers also comprises the procedures of washing, oiling, drying and the like. When spinning the filament, winding the filament into a tube through the working procedures; the spinning of staple fibers requires additional steps such as crimping, cutting, and baling.
Polyamides, which contain a number of repeating amide groups in the main chain, are called nylons when used as plastics and as nylon when used as synthetic fibers, are prepared from diamines and diacids, and can also be synthesized from omega-amino acids or cyclic lactams. According to the difference of carbon atom number in diamine and diacid or amino acid, a plurality of different polyamides can be prepared, the variety of the polyamide is dozens, and the polyamide-6, the polyamide-66 and the polyamide-610 are most widely applied.
