摘要(Abstract)：
为了尽可能地降低纤维染色过程中造成的污染,高效快速地达到纤维染色的目的,利用木质素对聚丙烯腈(PAN)纤维进行改性,并对改性纤维的色牢度以及相关热湿性能进行了研究。结果表明,利用木质素改性PAN纤维,其染色牢度达到使用标准,随着木质素的添加,纤维的回潮率、热收缩性能以及水接触角均有所降低。
In order to reduce the pollution caused by the fiber dyeing process as much as possible and achieve the purpose of fiber dyeing quickly and efficiently, self-dyed polyacrylonitrile(PAN) fibers were prepared by modifying with lignin, and the color fastness and related thermo-hygro properties of the modified fibers were studied. The results showed that the dyeing fastness of the lignin-modified PAN fibers all reached the application standard, and with the addition of lignin, the moisture regain, heat shrinkage and water contact angle of the modified fibers decreased.
