Explanation
The fiber made from natural polymer through chemical machining, which has basically the same composition as the original polymer but not completely the same physical structure, belongs to "natural modified man-made fiber". The main varieties include: ① plain fiber. Viscose fiber, cuprammonia fiber, new flux growth method cellulose fiber made from natural cellulose as raw material, and high-strength plain fiber made from cellulose acetate ester, which is highly stretched and saponified, are called Fortison. ② Regenerated protein fiber. The fiber is made from protein extracted from cheese, soybean, corn and peanut by wet spinning. ③ Chitin fiber. The fiber is made from chitin extracted from shrimp and crab shells by wet spinning. ④ Alginmefiber. Fibers made from alginate as raw material.
