Description
技术领域
本发明涉及一种二氧化钛改性机织物的颜料上色方法,属于纺织品加工技术领域。
背景技术
机织物是一种由经纬纱按照一定规律纵横交错而成的织物,广泛的应用在服装、帽子、装饰布、生物医用和工业用布等领域。随着科学技术的进步和发展,人们对机织物的要求越来越高,机织物的功能化改性技术也逐渐成熟起来。其中,采用二氧化钛对机织物进行改性最为常见,该方法能够赋予机织物良好的抗紫外性能、防红外性能和抗菌性能,提高机织物的附加值和使用领域。
但是,机织物经过二氧化钛改性后,不管采用染料染色或涂料染色,均无法获得颜色鲜艳的机织物产品。这主要是因为二氧化钛为纯白色,且其直径尺寸小于1微米,对可见光范围具有较高的反射率,因此致使染色后的机织物显现一定的哑白色,削弱了机织物颜色的鲜艳性和光泽度。
目前,国内外尚无有效的方法解决二氧化钛改性导致机织物颜色的哑白问题,所有的二氧化钛改性机织物产品均展现着其特殊的哑白色系。
发明内容
针对上述存在问题,本发明的目的在于克服上述缺陷,提供一种二氧化钛改性机织物的颜料上色方法,该颜料上色方法可有效的解决二氧化钛改性机织物后导致其颜色哑白的问题,为满足本发明目的的技术解决方案是:
一种二氧化钛改性机织物的颜料上色方法,颜料上色方法按以下步骤进行:
A二氧化钛改性机织物的回潮处理
将二氧化钛改性机织物放入温度为35-48℃,标准湿度为75-90%的恒温恒湿箱中进行回潮处理,回潮处理3-5h后的二氧化钛改性机织物的回潮率为0.5-0.8%;
B回潮后二氧化钛改性机织物表面的硅烷偶联剂键合
将经回潮处理后的二氧化钛改性机织物放入硅烷偶联剂乙醇溶液中进行浸泡,浸泡温度为50-60℃,浸泡30-50min后放入温度为80℃的干燥箱中进行干燥,干燥5h后得到表面键合有硅烷偶联剂的二氧化钛改性机织物,其中,硅烷偶联剂乙醇溶液中硅烷偶联剂的质量百分比为0.5-2%,二氧化钛改性机织物与硅烷偶联剂乙醇溶液的质量比为1:200;
C键合后的二氧化钛改性机织物表面自组装
将表面键合有硅烷偶联剂的二氧化钛改性机织物放入按如下质量百分比,
调配的自组装溶液中进行自组装,自组装温度为80℃,自组装20-30min后在表面键合有硅烷偶联剂的二氧化钛改性机织物的表面形成厚度为200-1200nm的自组装层,其中,二氧化钛改性机织物与自组装溶液的质量比为1:200;
D二氧化钛改性机织物表面的颜料上色
将经C步骤得到的自组装后的二氧化钛改性机织物放入按如下质量百分比,
偶氮颜料 3-8%
聚乙烯醇 0.3-0.5%
去离子水 91.5-96.7%
调配的颜料溶液中进行颜料上色,二氧化钛改性机织物与颜料溶液的质量比为1:200,上色温度为80℃,上色60-120min后得到颜料上色的二氧化钛改性机织物。
所述的二氧化钛改性机织物的平方米克重为80-220g/m2,经纬纱密度的范围为32-75根/10cm,经纬纱的纱支范围为50-90S。
所述的硅烷偶联剂为硅烷偶联剂KH-570或硅烷偶联剂KH-580或硅烷偶联剂KH-590或硅烷偶联剂SG-Si 123中的一种。
所述的偶氮颜料为C.I.颜料橙5或C.I.颜料红21或C.I.颜料黄12中的一种。
所述的聚乙烯醇的聚合物为1700,醇解度为99%。
由于采用了以上技术方案,本发明具有如下特点:
二氧化钛改性机织物常采用染料或颜料的方式进行上染,这些现有的方法使得染料或颜料与二氧化钛紧紧的接触在一起,或者间距较小,导致二氧化钛对光的高反射性削弱了染料或颜料的色深值和艳丽性。本发明所述的颜料上色方法区别于现有的染色技术和方法,在二氧化钛改性机织物表面先形成一层200-1200nm的分子层,该分子层由内至外依次由硅烷偶联剂和和十二烷基苯磺酸钠构成,然后在该分子层的外层以聚乙烯醇为粘结剂,将颜料固着在最外层,最终二氧化钛改性机织物上的二氧化钛与颜料之间形成几百纳米至几个微米的间隔。颜料在最外层直接受到光线照射时,其对可见光的高敏性可以使二氧化钛改性机织物显现出色度深和鲜艳度高的颜色。而紫外线和红外线可以透射过颜料层而进入间隔,间隔中的十二烷基苯磺酸钠的多分子层结构不会干扰紫外线和红外线,也不会发生耦合作用。当紫外线和红外线射入二氧化钛改性机织物上的二氧化钛时,紫外线和红外线均会被二氧化钛反射或散射,紫外线作用于二氧化钛诱发自由基可以使机织物保持抗菌作用,红外线被二氧化钛反射后可以使机织物具有一定的凉爽感。本发明所述的颜料上色方法可以使二氧化钛改性机织物获得色彩艳丽的颜色,同时保持二氧化钛改性机织物的功能性。另外,硅烷偶联剂乙醇溶液的质量、自组装溶液的质量、和颜料溶液的质量均以二氧化钛改性机织物的质量为基准,二氧化钛改性机织物与它们之间的质量比均为1:200。
本发明所述的一种二氧化钛改性机织物的颜料上色方法,颜料上色后的二氧化钛改性机织物可显现出色泽艳丽的橙、红和黄等色系,且本发明所述的颜料上色方法工艺简单,设备要求低,操作控制方便,易于实现工业化生产,无需特殊设备。
