The blend fibers of acrylonitrile-vinylidene chloride-sodium methallysulfonate copolymer(AN-VDC-SMAS) and cellulose acetate (CA) with various blend ratios were investigated bymeans of SEM, DDV, WAXD, etc. The results show that AN-VDC-SMAS and CA areincompatibale; the numerous microvoids in the blend fiber resulted from the phase seperationcan remarkably improve the water absorbability and the dyeing behavior but hardly influencethe mechanical properties. On the other hand, the crystal structure of the continuous phaseAN-VDC-SMAS is not influnced by the dispersed phase CA. 相似文献
