Description
技术领域
本发明涉及纺织技术领域，具体地说，是自清洁面料的制备方法。
背景技术
随着消费者生活质量的不断提升自清洁面料是指通过后期加工整理使面料具备超疏水或者光催化降解污染物的特殊性能，以此来减少衣物的洗涤次数或实现衣物免洗，减少洗涤剂的使用，最终达到节能、节水和环境友好的目的。
光催化自清洁面料的制备是将具有光催化效应的纳米颗粒负载于织物材料之上，从而使材料不仅可以通过光催化降解有机污染物，同时兼具杀菌除臭和防紫外线能力。光催化自清洁面料由于其多功能性和较高的附加值已经成为服装工业倍受关注的热点方向之一。如果采用有机涂层整理会影响服装的手感，透气性也会有所下降，同时有机涂层对人体和环境有害。
发明内容
本发明的主要目的在于提供一种自清洁面料的制备方法，其克服现有技术的不足，通过复合纳米材料的合成，以浸渍的方法进行后整理，制作一种纳米光催化自清洁面料，既有自清洁性，又能保持手感和透气性。
为达到以上目的，本发明采用的技术方案为：一种自清洁面料的制备方法，包括步骤：
S100将2,2'–二咪唑联苯和六水合硝酸锌加入到5％的磷酸二氢钠水溶液中，六水合硝酸锌浓度为1％～3％，搅拌，得到混合液；
S200将混合液在40～60℃下超声波震荡4～6小时，冷却至室温后过滤，将过滤产物分散于异丙醇中，在40～60℃下超声波震荡4～6小时；
S300震荡结束后，过滤，以饱和的氯化钠水溶液洗涤滤出物，干燥得到产物，与TiO2混合均匀；
S400将六偏磷酸钠、聚乙二醇、聚丙烯酸钠作复合分散剂，将2,2'–二咪唑联苯锌/TiO2和复合分散剂分散至水中，其中，2,2'–二咪唑联苯锌/TiO2的质量分数为3～5％，制得整理剂；
S500将超细涤纶面料在整理剂中浸渍，浸轧10min，烘干，制得所述自清洁面料。
根据本发明的一实施例，所述步骤S100中的2,2'–二咪唑联苯的合成，包括步骤：在二甲基亚砜溶剂下将2,2'–二氯联苯、咪唑、氢氧化钠和碘化亚铜在加热条件下制备2,2'–二咪唑联苯，其中2,2'–二氯联苯、咪唑、氢氧化钠、碘化亚铜的摩尔比为4：8：2：1，反应温度120℃，反应时间8小时。
根据本发明的一实施例，步骤S500具体包括步骤：将超细涤纶面料在整理剂中浸渍，浴比为1:20，50～70℃浸轧10min，80℃烘干。
根据本发明的一实施例，在所述步骤S100中的2,2'–二咪唑联苯和六水合硝酸锌的摩尔比为1～3：1。
根据本发明的一实施例，步骤S200中的异丙醇体积与步骤S100中的磷酸二氢钠水溶液体积相同。
根据本发明的一实施例，在步骤S300中，所得产物与TiO2的摩尔比为1～3:1。
根据本发明的一实施例，在所述步骤S400中的六偏磷酸钠、聚乙二醇、聚丙烯酸钠的摩尔比为1：1：1。
根据本发明的一实施例，2,2'–二咪唑联苯锌/TiO2和复合分散剂的摩尔比为1～3:1。
与现有技术相比，本发明的有益效果为：
(1)所述2,2'–二咪唑联苯锌/TiO2纳米材料光催化降解能力，可降解油污等污渍，并且可以赋予超细涤纶面料高的粗糙因子，使其不易沾染污渍。
(2)所述2,2'–二咪唑联苯锌/TiO2纳米材料具有电子-空穴对，可以收300nm-400nm的紫外光，紫外光具有更强的能量，会使与该材料接触的油污产生活性自由基，加之该面料表面具有较高的粗糙因子，因此，使用较少的洗涤剂或不使用洗涤剂就可轻松洗掉衣物表面的油污。
(2)所述自清洁面料可有效解决面料难清理的问题，省时省力，且减少了洗涤剂的使用，绿色环保，有极大的市场推广前景。
附图说明
图1是根据本发明2,2'–二咪唑联苯锌/TiO2的降解性能测试图。
具体实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的优选实施例只作为举例，本领域技术人员可以想到其他显而易见的变型。
2,2'–二咪唑联苯的合成，包括步骤：在二甲基亚砜溶剂下采用一锅法，将2,2'–二氯联苯、咪唑、氢氧化钠和碘化亚铜在加热条件下制备2,2'–二咪唑联苯，其中2,2'–二氯联苯：咪唑：氢氧化钠：碘化亚铜的摩尔比为4：8：2：1；反应温度120℃，反应时间8小时。
