Effect of xylan on viscose properties

The effect of xylan on viscose quality has been studied. An adverse effect of both alkali-soluble and alkali-insoluble xylan fractions on viscose quality (turbidity, CS2 distribution) has been found. This forms a basis for requirements on pentosan content of celluloses. It is suggested that evaluation of viscose fromleafy wood cellulose use the turbidity character istic.
