The essential chemical composition does not change,only part of the celluloseⅠ changes into celluloseⅡ. The crystallinity decreases about 25%;the dye uptake increases about 23%;dyeing rate increases significantly;fixation rate increases about 11%;dyeing properties improves significantly after alkali treatment.
结果表明,碱处理后棉纤维横截面由腰圆形变为近似圆形,中腔消失,纵向天然转曲消失,转变为光滑的近似圆柱体;而化学组成基本无变化,只是一部分纤维素Ⅰ转变为纤维素Ⅱ;结晶度下降了约25%左右;碱处理后棉纤维的上染百分率提高了约23%,上染速率显著提高,固色率提高了约11%,染色性能明显改善。
