微穴高吸湿PET纤维的制备与吸湿性研究

摘要

通过在PET切片中添加酸可溶的纳米级无机微粒制备纤维，将所制得的纤维用酸溶去无机微粒，得到微穴高吸湿PET纤维，用正交试验方法探讨了酸溶解的最佳工艺，结果表明酸处理的最佳工艺为：温度80℃，时间30min，酸浓度为4．5mol／L。%The micro hole high absorption polyester （PET） fibers can be prepared when the nanoscale inorganic particles mixed in PET fibers were dissolved by acid. In this paper, the acid treating technological parameters were discussed using orthogonal test method.
