Abstract

Highly absorbent regenerated cellulose fibres having water imbibitions which are usually in the range 150 to 300 per cent may be made by spinning cellulose fibres with a lumen and incorporating a dispersed polymer and/or substituent groups on the cellulose to increase the absorbency. The lumen may be produced by incorporating a blowing agent such as sodium carbonate in the viscose and may be either in expanded form to give a tubular structure or at least partially collapsed to give a multi-limbed structure. The polymer additive may for example be sodium polyacrylate, poly(vinyl pyrrolidone) or sodium carboxymethyl cellulose, and is suitably used in a concentration less than 5 per cent by weight. The fibres are useful in making swabs, dressings and catamenial tampons.
