Production method 100 kg of refined short cotton wool is immersed in 45% lye, the temperature is 35 ~ 40℃, the time is 0.5 ~ 1.0 h, and then take out for pressing. Stop pressing when the weight is 2.7 times the weight of cotton wool. To crush and loosen. Aged at 35℃ for 16 h.

Put the above-mentioned aged alkali fibers into the reactor, add chloromethane and propylene oxide in turn, react at 80℃ and pressure 1.8 MPa for 5 ~ 8 h, and then add appropriate amount of hydrochloric acid and oxalic acid washing materials in hot water at 90℃ to expand the volume. Use a centrifuge to dehydrate. Wash to neutral, when the water content in the material is less than 60%, dry at 130℃ hot air flow to less than 5% water content. Finally crushed through 20 mesh sieve to get the finished product.

The refined cotton cellulose is treated with lye at 35-40℃ for half an hour, pressed, the cellulose is crushed, and properly aged at 35℃, so that the average degree of polymerization of the obtained alkali fiber is within the required range. The alkali fiber was put into the etherification kettle, followed by the addition of propylene oxide and chloromethane, and etherized at 50-80℃ for 5h, with the highest pressure of about 1.8MPa. The reaction products are post-treated (hydrochloric acid neutralization, oxalic acid removal of iron, washing, drying). Raw material consumption quota cotton pulp 1100kg/t, methyl chloride and propylene oxide 4300kg/t, solid alkali 1200kg/t, hydrochloric acid 30kg/t, oxalic acid 50kg/t.

The production method is made of cellulose, chloromethane and ethylene oxide.

Stable and stable. Solids are flammable and incompatible with strong oxidants.
