Abstract
The present invention relates to a method for the production of highly absorbent polysaccharide fibers which contain a mixture of cellulose and α(1→3)-glucan as a fiber-forming substance, as well as to the highly absorbent fibers made thereby, and to their use.
Claims20
A method for the production of a highly absorbent polysaccharide fiber by a xanthogenate process comprising the steps of:
- (a) preparing an xanthogenate comprising alkali cellulose;
- (b) preparing a solution comprising α(1→3)-glucan and NaOH;
- (c) combining the xanthogenate of step (a) with the solution of step (b) to form a spinning solution, wherein a fiber forming substance in said spinning solution is a mixture of cellulose and α(1→3)-glucan;
- and
- (d) extruding said spinning solution to form said polysaccharide fiber.
