Abstract: | Conclusions 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.Translated from Khimicheskie Volokna, No. 1, pp. 43–44, January–February, 1987. |
