Chemical fiber fabrics are prone to static electricity.
Chemical fiber fabric is the abbreviation of chemical fiber. It is a textile made from a polymer compound as a raw material. Usually it is divided into two major categories of artificial fiber and synthetic fiber. Their common advantages are bright colors, soft texture, overhanging, smooth and comfortable. Their disadvantages are wear resistance, heat resistance, moisture absorption, and poor gas permeability, which are easily deformed by heat and are prone to static electricity.
A fiber made from a natural or synthetic high molecular material. Common textiles, such as viscose, polyester khaki, nylon stockings, acrylic yarns, and polypropylene carpets, are made of chemical fibers.
Chemical fibers can be classified according to the source of the raw materials:
1 rayon, using natural polymer materials (such as cellulose) as raw materials, viscose fiber, etc.;
2 synthetic fiber, using synthetic polymer as raw material, polyester, etc.;
3 Inorganic fiber, which uses inorganic materials as raw materials, and has glass fibers. Since the first artificial silk was extracted in the 18th century, chemical fiber varieties, fiber forming methods and spinning process technologies have made great progress.
Chemical fiber is usually prepared by spinning a natural or synthetic polymer or inorganic material into a spinning melt or solution, and then filtering and metering, and extruding it into a liquid stream by a spinneret (plate), followed by Solidified into fibers. The fibers at this time are called nascent fibers.
Its mechanical properties are very poor and cannot be directly applied. It must pass a series of post-processing steps to meet the requirements of textile processing and use. Post-processing is mainly to stretch and heat set the fibers to improve the mechanical properties and dimensional stability of the fibers.
Stretching is the orientation of macromolecules or structural units in the nascent fibers along the fiber axis; heat setting is primarily to relax the internal stress in the fibers. Post-processing of wet-spun fibers also includes processes such as water washing, oiling, and drying. When the filament is spun, it can be wound into a cylinder through the above process; when the short fiber is spun, the crimping, cutting and packing process must be added.
