Description
技术领域
本发明属于箱包布面料制造技术领域,具体涉及一种环保型防腐蚀箱包布面料及其制造方法。
背景技术
箱包是日常生活中的必备装备,用于存储容纳日常衣物等。随着时代的发展,用于制作箱包的面料从传统的真皮发展到聚酯、聚酰胺、PU、PVC等多种材质。
面料是箱包产品的主体材料,它不但直接影响产品的外观形象,还关系到产品的市场销售价格。能够用于箱包产品面料的原材料也有很多种,根据消费者的品位改变以及合成纤维的发展,箱包材质也更加多样化。在真皮、帆布、棉麻等质地箱包引领时尚潮流的同时,合成纤维也更多参与其中,如锦纶、涤纶等占据着相当重要的地位。
其中,PVC复合面料是最为常见的箱包制造面料之一。PVC是一种乙烯基的聚合物质,作为世界上产量最大的聚合物之一,其在实际的加工过程中,经常添加一定量的各种加工助剂,然后打粉混合,挤出造粒,最后通过多种加工工艺,制造出具有独特性价比的不同PVC制品。加工助剂主要有热稳定剂、增塑剂、润滑剂、色母料、辅助加工剂、抗冲击剂及其它添加剂等等。其中,热稳定剂主要用于吸收PVC受热加工时分解出来的游离氯,增塑剂用于使PVC制品具有一定的柔韧性,润滑剂用于使得PVC制品在造粒时更易于挤出,色母料用于使PVC制品具有各种颜色。由于制成的PVC制品具有不易燃性、高强度、耐气侯变化性以及优良的几何稳定性,且对氧化剂、还原剂和强酸都有很强的抵抗力,目前已被广泛应用于箱包制造行业。
但是,聚氯乙烯在高温塑化时,其中的增塑剂DOP(邻苯二甲酸二辛脂)有一定残留,对人体有一定伤害,欧盟出台的RECAH标准对此有限定。并且箱包面料往往由涂层剂在面料表面涂层制成,而涂层剂则多采用溶剂型聚氨酯等材料,这类材料虽然耐候性强,不易黄变褪色,成膜性好等优点,但其含有易挥发性溶剂,不环保。而且现有的箱包用面料易被割破,防火性比较差,同时,由于现有的箱包用面料的吸湿性高,因此不易防水,容易造成箱包内部腐蚀,从而很大的影响了箱包的质量。
发明内容
针对现有技术的不足,本发明的目的在于提供一种环保型防腐蚀箱包布面料及其制造方法。
为实现上述目的,本发明提供如下技术方案:
一种环保型防腐蚀箱包布面料的制造方法,包括以下步骤:
(1)涤纶纱线表面处理:将涤纶纱线依次用无水乙醇、去离子水进行洗涤并烘干,随后浸入KMnO4和盐酸混合液中浸泡,随后再进行紫外辐照处理,得到预处理涤纶纱线;
(2)纱线表面接枝:将步骤(1)中得到的预处理涤纶纱线加入到N,N-二甲基甲酰胺中,随后再加入丙烯酰胺、引发剂α-溴代异丁酸乙酯,进行搅拌反应,反应完成后洗涤、干燥得到表面接枝改性涤纶纱线;
(3)面料织造:将步骤(2)中制得的表面接枝改性涤纶纱线织造为面料;
(4)面料后整理:将步骤(3)中所得面料放入复合整理剂中,浸渍后烘干,得到后整理面料;
(5)面料表面涂覆涂层:将步骤(4)中所得后整理面料表面涂覆改性水性聚氨酯,涂布量为260-400g/m2,在100-130℃下烘干2-4h,即得所述环保型防腐蚀箱包布面料。
优选的,步骤(1)中盐酸的质量分数为5-10%,KMnO4和盐酸的质量体积比为1g:30-50mL。
优选的,步骤(1)中所述浸泡温度为70-90℃,浸泡时间为20-40min;步骤(1)中所述紫外辐照处理条件为:紫外辐照剂量为800-1200mJ/cm2。
优选的,步骤(2)中所述搅拌反应温度为100-120℃,反应时间为6-10h。
优选的,步骤(2)中预处理涤纶纱线、N,N-二甲基甲酰胺、丙烯酰胺、引发剂α-溴代异丁酸乙酯的质量比为10:50-80:3-5:0.2-0.5。
优选的,步骤(4)中浸渍温度为60-80℃,浸渍时间为4-7h,烘干温度为90-120℃,烘干时间为3-6h。
优选的,步骤(4)中所述复合整理剂的制备方法如下:
将40-50份全氟己基乙基丙烯酸甲酯、10-15份十二烷基三甲基硫酸铵、5-10份甲基三甲氧基硅烷、10-20份甲基丙烯酸异癸酯、5-8份对叔丁基苯甲酸混合均匀,在30-40℃下搅拌10-20min,随后再缓慢加入6-10份硬脂酸聚氧乙烯酯、10-15份硬脂酸锌、5-8份钼酸铵、2-5份月桂二酸,8-10min内投料完毕,最后加入200-250份去离子水,继续搅拌混合20-30min,即得所述复合整理剂。
优选的,所述步骤(5)中改性水性聚氨酯的制备方法如下:
(a)将3-吡咯羧酸、吡咯加入到去离子水中,加入二氧化钛和氧化锌粉末,在氮气氛围下加入氯化铁,搅拌混合均匀,在40-50℃下搅拌4-8h,发生原位聚合反应,过滤,洗涤,干燥后得到聚吡咯/二氧化钛/氧化锌螯合物;
(b)将步骤(a)中所得聚吡咯/二氧化钛/氧化锌螯合物、丙烯酸聚硅氧烷酯加入水性聚氨酯中,混合后得到所述改性水性聚氨酯。
优选的,所述步骤(a)中3-吡咯羧酸、吡咯、二氧化钛、氧化锌和氯化铁的质量比为10:6-7:1-3:1-2:15-17;步骤(b)中聚吡咯/二氧化钛/氧化锌螯合物、丙烯酸聚硅氧烷酯、水性聚氨酯的质量比为3-5:5-10:100。
本发明还保护一种利用上述方法制备得到的环保型防腐蚀箱包布面料在箱包上的应用。
与现有技术相比,本发明具有如下的有益效果:
(1)本发明提供的环保型防腐蚀箱包布面料的制造方法,通过对涤纶表面进行酸处理和紫外辐照,紫外光对材料的穿透力差,故接枝聚合可严格地限定在材料的表面或亚表面进行,不会损坏材料的本体性能,使得纱线表现具有更高的亲水性和更多的羧酸基团,从而提高丙烯酸在纱线表面的接枝速度和接枝率;接着通过在涤纶纱线表面接枝丙烯酰胺,改善了涤纶纱线的亲水性能和浸润性,使其在后续浸渍整理剂和涂覆涂层时,大大提高了与整理剂与水性涂料的附着性能,使得面料耐水洗性能更好且柔软度好。
(2)本发明提供的环保型防腐蚀箱包布面料的制造方法,通过将二氧化钛、氧化锌与羧基的聚吡咯通过螯合作用形成络合物,加入水性聚氨酯涂料,大大改善了二氧化钛和氧化锌的团聚问题,并且聚吡咯的加入提高了聚氨酯涂层的抗静电性;加入的丙烯酸聚硅氧烷酯,由于含硅共聚物表面能低,疏水性强,使得面料表面自由能减小,接触角增大,增强了面料的疏水性;同时,在紫外线照射下,二氧化钛和氧化锌会产生电子-空穴对,这些光产生的空穴将空气中贴附在涂料上的水分子分裂成OH-和H+离子,溶解的氧物质被还原为超氧阴离子(·O-2),其与H+反应生成(HO2·),然后它与多数电荷载流子(e-)和氢离子碰撞以产生过氧化氢分子,产生的过氧化氢分子可以穿透细胞质膜并杀死细菌细,达到生物防腐的效果,提高面料的耐腐蚀性。
(3)本发明提供的环保型防腐蚀箱包布面料,通过使用涤纶纱线为原材料,避免了聚氯乙烯中增塑剂DOP的残留,同时使用的涂层涂料为水性聚氨酯,在保证了耐候性强、不易黄变褪色和成膜性好等优点时也对环境友好。

将实施例1-3和对比例1-3制备得到的环保型防腐蚀箱包布面料进行性能测试,采用接触角测试仪,分别测试样品与去离子水的接触角,以判定疏水性;对面料的抗菌性能(参考GB/T 20944.3-2008《纺织品抗菌性能的评价第3部分:振荡法》,测试面料对大肠杆菌的抑菌率);溶剂残留-DMFu采用GC-MS分析,测试结果如下表1:
表1各面料性能测试结果
疏水角/° | 抗菌率/% | 溶剂残留-DMFu(mg/kg) | |
实施例1 | 157 | 98.6 | 未检出 |
实施例2 | 166 | 99.3 | 未检出 |
实施例3 | 164 | 98.8 | 未检出 |

按照JIS L-0217-103方法,对实施例1-3和对比例1-3制备得到的环保型防腐蚀箱包布面料反复洗涤30次和50次,然后评价疏水性和抗菌性,测试结果如下表2:
表2各面料在洗涤30次和50次后的性能测试结果
从表1中可以看出,本发明提供的环保型防腐蚀箱包布面料具有良好的疏水性能和抗菌率,且无溶剂残留,其环保性良好;并且经过50次反复洗涤后该织物仍具有较优异的疏水抗菌性能,说明本发明的面料在经过表面改性后,与整理剂和水性聚氨酯涂料的附着性能较强,提高了面料的耐水洗性能。对比例1中由于未对涤纶纱线表面进行表面改性,其综合性能有所下降;对比例2中未对涤纶纱线表面进行表面改性且未浸入复合整理剂,性能下降较为明显;对比例3未对涤纶纱线表面进行表面改性且未对水性聚氨酯改性,其疏水性能和耐洗涤性能下降明显,且无抗菌性。
尽管已经示出和描述了本发明的实施例,对于本领域的普通技术人员而言,可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型,本发明的范围由所附权利要求及其等同物限定。
