Man-made fibers are produced by combining polymers or small molecules. It is created from natural materials or by chemical processes. Man-made fibers account for 70% of all fibers produced worldwide. Man-made fibers were first created to improve upon natural fibers and are categorized into two groups: regenerated and synthetic fibers. The typical manufacturing process flowchart of man-made fiber production is as follows:
Flow Chart of Man-made Fiber Production
Manufacture of the fiber forming polymer
Spinning (Extrusion through spinneret)
Stretching/Drawing (Improving strength and crystalinity)
Texturing/Crimping (Developing natural fiber properties)
Intermingling/Interlacing (Applied instead of twisting)
Heat setting (Made dimensionally stable)
Synthetic fiber is that which is made from different types of polymers. It is not cultivated as a natural fiber. Manmade fiber is produced from the reaction between different types of monomers. By the polymerization process, a long chain of polymer is produced. Then filament is produced by the various spinning process. Various types of synthetic fiber are available in the market Day by day its availability increases for its cheap price. But there have lots of bad effects of man-made fiber on the environment.
Man-made fiber, fiber whose chemical composition, structure, and properties are significantly modified during the manufacturing process. Man-made fibers are spun and woven into a huge number of consumer and industrial products, including garments such as shirts, scarves, and hosiery; home furnishings such as upholstery, carpets, and drapes; and industrial parts such as tire cord, flame-proof linings, and drive belts. The chemical compounds from which man-made fibers are produced are known as polymers, a class of compounds characterized by long, chainlike molecules of great size and molecular weight. Many of the polymers that constitute man-made fibres are the same as or similar to compounds that make up plastics, rubbers, adhesives, and surface coatings.
