补充资料：醋酸纤维
分子式：
CAS号：
性质：又称醋酸纤维。是纤维素酯纤维的主要品种。泛指二醋酯纤维和三醋酯纤维；习指二醋酯纤维。指由从棉短绒、木材等植物材料中提取和纯化得到的纤维素为原料，与醋酸酐反应生成含结合醋酸量达61.5%～62.5%的三醋酸纤维素酯，也称初级醋酸纤维素酯(primary cellulose acetate)，再经部分水解获得含结合醋酸量达53.5%～56%的二型醋酸纤维素酯(secondary cellulose ac-etate)后，使之溶解于丙酮中所制得的纤维。该纤维的相对密度1.32，干态强度1.15～1.32cN/dtex，伸长率25%～35%，公定吸湿率6.5%，干湿态强度比60%～65%。该纤维的束状产品主要用于制作香烟过滤嘴，少量长丝制的织物用作高档的里子布等。
