<p>Carboxymethyl cellulose fibre having a degree of substitution of at least 0. 1, preferably 0.2-0.5, carboxymethyl group per glucose unit, is derived from solvent-spun cellulose fibre, for example by reaction with a strong alkali and a monochloroacetate reagent. The fibre has an absorbency of at least 8 grams, usually at least 1 5 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.</p> |
