Description
技术领域
本发明涉及纺织品技术领域，具体为一种光动力抗菌遮阳织物。
背景技术
抗菌纺织品具有杀菌、抑菌功能，有益人们的健康生活，一方面，抗菌纺织品能够防止人体皮质、汗液等代谢物质与织物结合滋生大量微生物，降低了病原微生物传染疾病的风险，同时能够减少微生物繁殖产生的异味；另一方面，对于纺织品本身来说，其抗菌功能也能够保护织物自身，减少织物在使用过程中受到的微生物侵蚀，延长纺织品的使用寿命，提高使用价值；因此，品质可靠、安全性强的抗菌纺织品深受市场青睐。
传统的抗菌剂如抗生素、季铵盐等药物则易引起菌类的变异从而形成耐药菌株，且对人体存在潜在的毒副作用；铜、银等金属纳米颗粒非常贵，且很难在材料中达到良好分散并且容易析出；天然抗菌剂最为绿色，但抗菌效果有所限制；相比于传统的无机、有机抗菌剂，新型材料石墨烯基本没有细胞毒性，但难溶于水难以与织物纤维结合，且价格同样相对昂贵。
光是自然界中最易于获取的资源之一，在许多生物的生理过程中也扮演着重要角色，光介导抗菌就是在光照条件下灭活细菌的新型抗菌策略；一般而言，光介导抗菌策略主要包含紫外杀菌、光动力抗菌和光热抗菌三类；在生活中，紫外杀菌已被广泛使用，这是由于紫外线具有兆焦级别的能量，能够快速杀灭细菌，但是这种短波紫外线的组织穿透能力很弱，并且极有可能会对人体正常细胞造成伤害，威胁人类健康，光动力抗菌和光热抗菌则使用组织穿透能力较好的红光和近红外光，分别产生活性氧和局部高温从而杀灭细菌，光动力抗菌是一种十分有前景的抗菌机制：在分子氧存在的环境中，光敏剂在可见光照射下产生可以杀灭微生物的活性氧（ROS），其中最主要的是单线态氧（1O2），由于单线态氧和自由基引起的是非特异性细胞损伤，故而对耐药菌株同样有效，且不会在多次光敏作用中引发新的细菌抗药性，同时，ROS的瞬时生命周期（µs）保证了光敏剂的环境友好性。
设计一种光动力抗菌遮阳织物，在使用过程中不但能遮阳，在光照条件下，还可以对织物上的细菌进行杀灭，可以改善室内环境，减少使用者有害细菌感染几率，延长织物的使用寿命。
发明内容
本发明的目的在于提供一种光动力抗菌遮阳织物，通过涂层叠贴合的方式加工而成，抗菌遮阳织物不仅有遮阳效果，还可在光照条件下，有效杀灭织物上的细菌，通过涂布含氨基硅油的透明涂层浆，赋予遮阳织物较好的手感。
为实现上述目的，本发明提供如下技术方案：一种光动力抗菌遮阳织物，其结构包括面料基层、设置在面料基层上的遮光层、设置在遮光层上的光动力抗菌层、设置在光动力抗菌层上的软面浆层，所述面料基层先经拒水整理后，再通过层叠复合的涂层加工，在面料基层上方形成遮光层、光动力抗菌层和软面浆层。
进一步地，所述面料基层是经提花、染色或印花加工，并经过防水整理的涤纶或锦纶长丝机织物，克重为80～120 g/m2。
进一步地，所述设置在面料基层上的遮光层是将二氧化钛浆料、稳泡剂混合于聚丙烯酸酯乳液中制备成发泡涂层浆，浆料中加炭黑可得黑色色浆，不加炭黑为白色色浆，遮光层按白色色浆、黑色色浆和白色色浆次序，三层涂布于窗帘织物表面，每次涂层后焙烘而成，其中遮光层克重40-60 g/m2。
进一步地，所述设置在遮光层上的光动力抗菌层是将光动力抗菌剂（亚甲基蓝、劳氏紫、孟加拉玫瑰红等）、稳泡剂混合于聚丙烯酸酯乳液中制备成光动力抗菌发泡浆，涂布在遮光层上焙烘而成，其中光动力抗菌剂在浆料中的添加量为1～5g/L，光动力抗菌层克重10-30g/m2。
进一步地，所述设置在光动力抗菌层上的软面浆层是将含氨基硅油混合于聚丙烯酸乳液中制备成涂层浆，涂布在光动力抗菌层焙烘而成，软面浆层克重25～40 g/m2。
与现有技术相比，本发明的有益效果是：
本发明提供的一种光动力抗菌遮阳织物，其结构由面料基层、遮光层、光动力抗菌层和软面浆组成，其中面料基层赋予遮阳织物外观效果；遮光层中含有白、黑、白三层发泡涂层起到优良的遮光效果，光动力抗菌层中含有光动力抗菌剂，能有效杀灭织物上的细菌；软面浆层不仅赋予织物较好手感，而且有透光性，保证可见光能透过软面浆层进入光动力抗菌层，引发光动力抗菌剂发挥抗菌作用；由此可见，本发明提供的一种光动力抗菌遮阳织物，可应用于室内窗帘加工，具有很好的遮阳、抗菌功能。

请参阅图1，本发明提供一种光动力抗菌遮阳织物，其结构包括面料基层1、设置在面料基层1上的遮光层2、设置在遮光层2上的光动力抗菌层3、设置在光动力抗菌层3上的软面浆层4，所述面料基层1先经拒水整理后，再通过层叠复合的涂层加工，在面料基层1上方形成遮光层2、光动力抗菌层3和软面浆层4；
面料基层1是经提花、染色或印花加工，并经过防水整理的涤纶或锦纶长丝机织物，克重为80～120 g/m2，面料基层1赋予遮阳织物外观效果；
设置在面料基层1上的遮光层2是将二氧化钛浆料、稳泡剂混合于聚丙烯酸酯乳液中制备成发泡涂层浆，浆料中加炭黑可得黑色色浆，不加炭黑为白色色浆，遮光层按白色色浆、黑色色浆和白色色浆次序，三层涂布于窗帘织物表面，每次涂层后焙烘而成，其中遮光层2克重40-60 g/m2，遮光层2中含有白、黑、白三层发泡涂层起到优良的遮光效果；
设置在遮光层2上的光动力抗菌层3是将光动力抗菌剂亚甲基蓝、劳氏紫、孟加拉玫瑰红等、稳泡剂混合于聚丙烯酸酯乳液中制备成光动力抗菌发泡浆，涂布在遮光层上焙烘而成，其中光动力抗菌剂在浆料中的添加量为1～5g/L，光动力抗菌层3克重10-30g/m2，光动力抗菌层3中含有光动力抗菌剂，能有效杀灭织物上的细菌；
设置在光动力抗菌层3上的软面浆层4是将含氨基硅油混合于聚丙烯酸乳液中制备成涂层浆，涂布在光动力抗菌层焙烘而成，软面浆层4克重25～40 g/m2，软面浆层4不仅赋予织物较好手感，而且有透光性，保证可见光能透过软面浆层4进入光动力抗菌层3，引发光动力抗菌剂发挥抗菌作用。
以上所述仅是本发明的具体实施方式，但本发明的保护范围并不限于此。可以理解，本领域技术人员在不脱离本发明的基本构思的前提下直接导出或联想到的其他改进和变化，均应认为涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书所限定的保护范围为准。
