Description
技术领域
本发明涉及纺织面料技术领域,具体为一种超疏水棉麻纺织面料,此外还涉及一种超疏水棉麻纺织面料的制备方法。
背景技术
棉麻纺织面料是由棉和麻交织的布料,具有较多的优点,例如棉麻面料透气性好,身体出汗后,能够及时随着空气散发到面料的外部;质地柔软,冬暖夏凉,舒适性好。目前市面上的棉麻纺织面料在防水疏油有一定的作用,但其防水疏油稳定性较差,使用一段时间后,并且伴随着水洗,防水疏油层会渐渐消失,失去防水疏油的功能,和普通的棉麻纺织面料不再有区别,在生活中碱性物质和自然损耗是破坏疏水能力的主要原因,因此,需要一种改进的技术来解决这一问题。
于是,有鉴于此,针对现有的结构及缺失予以研究改良,提供一种超疏水棉麻纺织面料及其制备方法,以期达到更具有更加实用价值性的目的。

S2、清洁:
将棉麻纺织品放进水中清洗,清洗完成后使用烘干机进行烘干;在烘干的过程中可以利用紫外线灯或臭氧进行杀菌,确保棉麻纺织品洁净,不应影响棉麻纺织品的吸酸性溶液;
S3、制取酸性溶液:
将磷酸二氢钠加入适量水中,调节水的pH值为6—7,将S1中的棉麻纺织品放入水中浸泡,然后取出烘干;磷酸二氢钠和水以及棉麻纺织品加入到搅拌器中,持续搅拌30—60min,水和磷酸二氢钠的用量根据小加工的棉麻纺织品决定,确保水的pH值在6—7之间即可;
S4、浸泡:
将S2中棉麻纺织品以及聚四氟乙烯蜡5—10g放入100ml水中,然后向水中加入氧化剂2—6g,浸泡60—90min;当水的用量增多时,根据水的用量增加聚四氟乙烯蜡和氧化剂的用量,防止出现疏水效果差的问题;
S5、催化:
向S3中的溶液加入催化剂0.01—0.03mol,并加热到65—75℃,持续30—60min,
S6、改性:
将S4中的溶液温度调节到40—50℃,然后加入偶联剂0.3—0.5g,搅拌20—30min;S4和S5在同一个设备中完成;
S7、成型:
取出S5中的棉麻纺织品并干燥,再将干燥后的棉麻纺织品在—8—3℃环境中放10—15min,再在35—45℃环境中放置10—15min,如此高低温交替进行3—5次,疏水层3在棉麻纺织品表面形成;
S8;,清洗,将S6棉麻纺织品浸入去离子水清洗5—10min,然后经干燥得到超疏水棉麻纺织面料。
进一步的,所述S3步骤中氧化剂为脂肪醇聚氧乙烯醚、高碘酸钠、高碘酸钾、次氯酸钠、过氧化钠中的一种,可以根据物料成本选择合适的氧化剂;
进一步的,所述S4步骤中催化剂为酸性催化剂,酸性催化剂为甘醇酸、乙酸、氯化氢中的一种。
进一步的,所述S5步骤中偶联剂为十三氟辛基三甲氧基硅烷、全氟癸基三甲氧基硅烷、全氟辛基三氯硅烷中的一种。
进一步的,所述棉麻纺织品的原料为白棉、彩棉、有机棉、亚麻、剑麻中的一种,上述原料通过相应的纺织器械最终加工成棉麻纺织品。
与现有技术相比,本发明的有益效果是:本发明通过酸性溶液以及酸性催化剂使得棉麻纺织面料偏向于酸性,具有疏水效果的棉麻纺织面料在日常使用时,其疏水周期大大延长,面对碱性物质,对其进行中和,防止碱性物质破坏疏水效果,从而使棉麻纺织面料具有较好的且周期长的疏水功能,利用偶联剂和高低温对棉麻纺织面料的疏水能力进行强化,使得棉麻纺织面料在复杂的环境下依然保持稳定法的疏水能力,且不易磨损,环保安全,经久耐用。
