Are polyester fiber or spandex fiber or fiber?
Polyester fiber and spandex belong to chemical fiber or fiber.Chemical fiber usually refers to chemical fiber.Chemical fiber is made of natural macromolecule compound or synthetic macromolecule compound, which is prepared by spinning, dope, spinning and post-treatment.
Fiber is a substance consisting of continuous or discontinuous filaments. In animals and plants, fiber plays an important part in the maintenance of tissues. Fiber is widely used, can be woven into thread, thread and rope, paper or woven mat can also be woven into the fiber layer; also used to manufacture and other materials, and other materials composed of composite materials.
Fiber length, thickness, whiteness, gloss and other properties can be adjusted in the production process. And with excellent light fastness, wear resistant and easy to clean and no mildew, moth eaten etc.. Widely used in the manufacture of clothing fabric, cloth, conveyor belts, hoses, ropes, nets, electrical insulation, medical suture line, tire cord and parachute etc.. In general, polymers can be made into solutions or melts, extruded from the pores of the spinneret, and then solidified into fibers. The product can be without stop filament, cut to length of staple fibers or without cutting tow etc.. Chemical fiber product name, China Interim Provisions "all synthetic staple fiber" (e.g., nylon, polyester), short cellulose fiber are "fiber" (for example, viscose fiber, copper ammonia), filament in Matsuo Kachi "silk", or "Lun", "fiber", instead of "silk".
