Carboxymethylcellulosefaser

摘要

Carboxymethyl cellulose fiber having a degree of substitution of at least 0.1, preferably 0.2-0.5, carboxymethyl groups per glucose unit is derived from solvent-spun cellulose fiber, for example by reaction with a strong alkali and a monochloroacetate reagent. The fiber has an absorbency of at least 8 grams, usually at least 15 grams, 0.9% saline solution per gram of fibre and a tenacity of at least 10, usually at least 15, cN/tex. It can be used for absorbent personal products.
