Description

一种粘附性强的复合纺织浆料及其制备方法
技术领域
本发明涉及纺织浆料技术领域,具体涉及一种粘附性强的复合纺织浆料及其制备方法。
背景技术
经纱上浆是织造工程的关键环节,浆纱的目的主要是提高纱线的耐磨性,减少毛羽,适当增加纱线的强力,减少伸度,以承受经纱在织造过程中受到的机械作用力,提高纱线的可织性。随着纺织大型轻化工企业特别是纺织企业数量大量增加,纺织浆料的使用量也越来越多,现在纺织浆料是纺织行业除纺织纤维外消耗的第二大材料,我国的年消耗量已达到百万吨之多。
变性淀粉、聚乙烯醇和聚丙烯酸类浆料是目前广泛使用的三大纺织上浆用浆料。目前在国际市场上,淀粉浆料用量约占浆料总用量的74%,聚乙烯醇和丙烯酸类浆料分别约占11% 和12% ,其它浆料为3%左右。经纱上浆的浆料结构为:一般纯棉织物以原淀粉或变性淀粉为主。而纯化纤及其混纺织物,则根据各国资源条件不同而不同。在日本以改性聚乙烯醇为主;在美国使用聚乙烯醇和变性淀粉混合浆料,丙烯酸类浆料为辅助浆料;欧洲国家以变性淀粉为主体浆料,丙烯酸类浆料为辅助浆料。我国在近年来,变性淀粉得到了迅速发展,品种也越来越多。目前在我国,淀粉浆料约占70% ,聚乙烯醇约占20% ,丙烯酸类浆料及其它浆料占10% 左右。我国浆料的使用结构比较复杂。一般纯棉中高特织物大多采用原淀粉或变性淀粉为主,辅以少量聚乙烯醇或丙烯酸类浆料。纯棉低特高密织物采用变性淀粉与聚乙烯醇混合浆料。有些以聚乙烯醇为主体浆料,一般为浆料总量的60% 左右,变性淀粉为30%~40% ,再辅以丙烯酸类浆料;有些以变性淀粉为主体浆料,一般为浆料总量的60% ,聚乙烯醇为30%~ 40% ,再辅以丙烯酸类浆料或CM C (CM S) 浆料。对涤棉织物上浆大多采用聚乙烯醇与变性淀粉的混合浆,以聚乙烯醇为主体,变性淀粉用量为30%~ 40% ,再添加丙烯酸类浆料或CM C (CM S) 浆料;有的还采用以聚乙烯醇为主的纯化学混合浆。
对于上述几种浆料而言,变性淀粉浆料是纺织上浆的主浆料组分,与天然纤维亲和力强,成膜性好,易于退浆,但由于淀粉大分子链是由环状结构的葡萄糖剩基构成的,玻璃化温度较高,大分子链的柔顺性较差,因此淀粉类浆料的浆膜硬而脆,且与涤纶纤维的亲和力较差,粘附性能不够。聚乙烯醇浆料成膜性好,且浆膜强度高、弹性好,对天然纤维和合成纤维都具有较好的粘附性,但聚乙烯醇浆料的生物降解性较差,欧洲一些国家已禁止使用聚乙烯醇浆料。聚丙烯酸类浆料是取代聚乙烯醇浆料发展的重要方向。聚丙烯酸类浆料按照侧链官能团的不同,可分为三类:聚丙烯酰胺,聚丙烯酸及其盐类,聚丙烯酸酯类。聚丙烯酰胺是一个亲水性很强的浆料,因此对疏水性强的涤纶纤维的粘附性不足。聚丙烯酸浆料是锦纶的适用浆料,但对涤纶纤维的粘附性较弱。且聚丙烯酰胺、聚丙烯酸及其盐类浆料吸湿再粘性大,只能少量使用于混合浆料中。聚丙烯酸酯类浆料主要是丙烯酸甲酯及丙烯酸丁酯共聚物,为了水溶的需要,配以丙烯酸共聚单体;这类浆料对合成纤维具有较好的粘附性能,但吸湿和再粘性较强,玻璃化温度低,浆膜较软,限制了其作为主浆料的使用。且聚丙烯酸类浆料多采用乳液聚合法生产,乳化剂的存在往往会恶化其使用性能,如产生泡沫、影响与其它浆料的相容性等。
因此,为了克服上述纺织浆料的缺点,目前纺织浆料的发展趋势主要是:(1)适应环境保护和产品开发的要求,浆料产品应向“少组份、高质量、多功能、系列化、少用或不用聚乙烯醇”的方向发展;(2)加速高质量高性能变性淀粉的开发;(3)开发更新一代的丙烯酸类浆料;(4)在配浆上浆标准化、规范化的基础上,开发各大类产品的组合浆料。同时,在向上述方向发展的基础上,进一步提高纺织浆料自身的固有性能,已解决目前现有新型纺织浆料粘附性能欠缺的问题也是尤为必要的。
