Segondè klas acetate fib tow pou materyèl tabak

Select high-quality cellulose raw materials, such as wood pulp or cotton linters, and go through pretreatment processes such as impurity removal and crushing to prepare for subsequent dissolution. Mix the treated cellulose raw materials with solvents (such as dichloromethane, acetone, etc.), dissolve under high temperature and high pressure conditions to form a viscous Solisyon Cellulose . Ajoute anidrid acetic ak lòt ajan esterifying nan solisyon an karboksimetil, ak pote soti nan reyaksyon esterifikasyon anba aksyon an nan katalis, se konsa ke gwoup yo idroksil nan molekil yo cellulose yo ranplase pa ACETATE gwoup yo pwodwi diacetate celluled {{{{ Filaman, epi apre beny koagulasyon, etann, siye ak lòt pwosesis, se diacetate fibre fib finalman jwenn .
