Chemical fibers refer to textile fibers made from natural or synthetic polymers and processed through chemical and mechanical methods. According to the morphological characteristics of chemical fibers, they can be pided into two categories: long fibers and short fibers. According to the cross-sectional morphology and structure of chemical fibers, they can be further pided into irregular fibers and composite fibers. According to fiber thickness, it can also be pided into coarse, fine, and ultrafine fibers. Detection scope: Natural fibers: plant fibers, animal fibers, mineral fibers Chemical fibers: artificial fibers, synthetic fibers, inorganic fibers Artificial fibers: viscose fibers, acetate fibers, copper ammonia fibers, regenerated cellulose fibers, regenerated protein fibers, regenerated starch fibers, regenerated synthetic fibers. Synthetic fibers: polyester fiber (polyester), polyamide fiber (nylon or nylon), polyvinyl alcohol fiber (vinylon), polyacrylonitrile fiber (acrylic), polypropylene fiber (polypropylene), polyvinyl chloride fiber (chloroprene), etc. Inorganic fibers: glass fibers, metal fibers, carbon fibers, etc P>
