Description

一种上浆均匀且易退浆的纯棉纱线上浆剂
技术领域：
本发明涉及纺织业技术领域，具体涉及一种上浆均匀且易退浆的纯棉纱线上浆剂。
背景技术：
为了防止纱线在织造时产生断头，提高工作效率，将纱线用浆料进行处理以增加其强度，称为上浆。目前，常用浆料包括变性淀粉、聚乙烯醇和丙烯酸类三种。其中，淀粉对亲水性的天然纤维有着较好的粘附性，也有一定的成膜能力，易降解，但粘度波动大，糊化性能差，需要加入大量的助剂。丙烯酸类浆料对各类纤维都具有优良的粘附性，水溶性好，易于退浆，但其最大的缺点是吸湿再粘性较严重，价格高，目前在国内只用作辅助浆料。而聚乙烯醇是一种典型的水溶性高分子化合物，具有优良的成膜性、良好的粘附性及与其他浆料相容性好，但不易分纱、再生毛羽多，并且退浆难度大，增加退浆成本。
发明内容：
本发明所要解决的技术问题在于提供一种能显著增强纱线强度、与辅助浆料相容性好的上浆均匀且易退浆的纯棉纱线上浆剂。
本发明所要解决的技术问题采用以下的技术方案来实现：
一种上浆均匀且易退浆的纯棉纱线上浆剂，由如下重量份数的原料制成：
聚氧化乙烯10-15份、线性低密度聚乙烯4-8份、卡波树脂3-6份、交联聚维酮3-6份、C5加氢石油树脂2-4份、水溶性壳聚糖2-4份、聚乙烯醇缩丁醛1-2份、氢化蓖麻油1-2份、超细聚四氟乙烯粉末0.5-1份、纳米钛白粉0.5-1份、稀土复合添加剂0.1-0.3份、水100-150份。
其制备方法包括如下步骤：
(1)向水中加入聚氧化乙烯、线性低密度聚乙烯和C5加氢石油树脂，加热至回流状态保温混合30min，再加入卡波树脂和超细聚四氟乙烯粉末，继续回流保温混合15min，即得物料I；
(2)向交联聚维酮中加入聚乙烯醇缩丁醛和氢化蓖麻油，加热至95-100℃保温混合10min，然后加入水溶性壳聚糖和纳米钛白粉，继续保温混合5min，即得物料II；
(3)向物料I中加入物料II和稀土复合添加剂，充分混合均匀，所得混合物加入球磨机中，球磨至细度小于30μm。
所述卡波树脂使用前经过预处理，其处理方法为：将15-20份卡波树脂加入3-5倍重量份水中，并加入1-2份羧甲基纤维素钠和0.5-1份硬脂酰乳酸钠，分散均匀后加热至回流状态保温混合15min，再加入0.5-1份明胶和0.2-0.5份苯并咪唑，继续回流保温混合10min，所得混合物送入冷冻干燥机中，经充分干燥后将所得固体粉碎成粉末。
所述卡波树脂选自卡波树脂940、卡波树脂934、卡波树脂941中的一种。
由于卡波树脂易溶胀，经过上述预处理后显著降低其溶胀性，使卡波树脂溶于水后形成均匀浆体。
所述C5加氢石油树脂使用前经过亲水改性，其改性方法为：向10-15份C5加氢石油树脂中加入1-2份阴离子聚丙烯酰胺、0.5-1份松节油和0.5-1份聚季铵盐，充分混合后利用微波处理器微波处理5min，静置30min后再次微波处理5min，然后加入1-2份微晶纤维素和0.5-1份水解聚马来酸酐，混合均匀后继续微波处理5min，随后以10℃/min的冷却速度降温，待温度降至0-10℃后保温静置1h，再以5℃/min的加热温度升温，待温度升至100-105℃后保温混合15min，并将所得混合物缓慢滴入10-15℃水中，滴加完毕后混合15min，最后送入喷雾干燥机中，经充分干燥后即得亲水颗粒。
所述微波处理器的工作条件为微波频率2450MHz、功率700W。
C5加氢石油树脂经过上述亲水改性，提高其亲水性，利于与其余原料的共混，从而在提高使用性能的基础上保证所制浆料的均匀性。
所述稀土复合添加剂由如下重量份数的原料制成：微晶蜡2-3份、鲸蜡醇1-2份、马来酸酐接枝相容剂0.5-1份、氧化镧0.1-0.3份、氧化铈0.1-0.3份、氧化钇0.05-0.1份、异丙醇10-15份，其制备方法为：向异丙醇中加入微晶蜡、鲸蜡醇和马来酸酐接枝相容剂，加热至回流状态保温混合15min，再加入氧化镧、氧化铈和氧化钇，继续回流保温混合10min，然后自然冷却至室温，将所得混合物送入喷雾干燥机中，最后将干燥所得颗粒粉碎成粉末。
通过稀土复合添加剂的加入，不仅提高上浆率，还能增强上浆后纱线的强度。
本发明的有益效果是：本发明所制上浆剂适用于纯棉纱线，水溶性好，对天然纤维有着较好的粘附性，上浆均匀且成膜性强，上浆率达到8％左右，能均匀粘附在纤维上形成一层超薄的浆膜，以提高纯棉纱线的强度，使纱线光洁、富有弹性、耐磨、断经断纬少；同时与辅助浆料相容性好，退浆容易，降低退浆成本；并且上浆过程中产生的废水易处理，通过常规废水处理后即可排放，减轻对环境的污染。
