Cellulose acetate fiber production

Continuous measurement and control of influent concentration, in order to realize high quality cellulose acetate fiber production

Cellulose fiber has two kinds: regeneration or pure cellulose (such as through copper ammonium method, cellulose) and modified cellulose fiber (such as cellulose acetate and rayon fiber.

Acetate fiber is a substance formed by cellulose acetate.Cellulose acetate by dissolved the wood pulp for pure cellulose.After taking sulfuric acid as catalyst, the purification of cellulose with acetic acid and acetic anhydride reaction, to the preparation of cellulose acetate dope.Then, the mixture hydrolysis and remove sulphate, product can be up to standard.In the end, will be formed in the acid resin flake dissolved in acetone solution and filtering.

In the next stage, squeezing the spinning dope, solvent recovery and purification and recycle.After drawing the fiber filament winding on the winding drum, obtain the finished product.

Visa K - PATENTS^®In situ refractometer can online monitoring of the concentration of the spinning dope before fiber spinning.To accurately measure can promote concentrate output quality of the finished product.

Can be installed in the solvent recovery another refractometer, so that the recovery of acetone and reduce operational costs.

Read the application instructions, detailed understanding of acetate fiber production process.
