【摘要】 采用潜交联剂丙烯酸羟丙酯与丙烯酸、丙烯酰胺等单体共聚后与聚乙烯醇共混配制成纺丝原液, 湿法纺丝成形后经后交联处理赋予纤维三维网状结构,制得具有较好吸水性能的丙烯酸-丙烯酰胺共聚物/ 聚乙烯醇共混纤维,研究了后交联处理条件对纤维结构及性能的影响。结果表明,随着交联温度的升高,交联时间的延长,纤维的饱和吸水率降低。纤维经130℃交联处理12 min后,其饱和吸水率可达405 g/g。更多还原

【Abstract】 A potential crosslinking agent, 2-hydroxypropyl aerylate, was introduced into the macromolecular chain of copoly ( acrylic acid-acrylamide). The blends of the said copoly (acrylic acid-acrylamide) and poly ( vinyl alcohol) were spun into fiber in coagulation. A three-dimensional network structure can be obtained after after-crosslinking treatment. The obtained blend fiber of copoly (acrylic acid-acrylamide) and PVA had fairly good water absorbability. The effects of after-crosslinking conditions on the structure and properties of the fibers were studied. The result showed that the saturation water absorbency was decreased while raising crosslinking temperature and prolonging crosslinking time and was maximized as 405 g/g after crosslinking treatment for 12 min at 130℃.更多还原
