Description

用于织物、无纺布与多孔性薄膜的等离子改性方法及系统
技术领域
本发明属于材料技术领域，具体涉及一种用于织物、无纺布与多孔性薄膜的等离子改性方法及系统。
背景技术
等离子体已广泛应用于各种领域，如在半导体集成电路制造方面，不同材料薄膜的成长及电路的蚀刻等多普遍由等离子体技术达成。另外在半导封装及纺织业方面，可以使用等离子体来清洁及改变材料表面以达到特殊的功能及效果；在环保方面,等离子体火炬可以安全固化焚化炉所产生的高污染灰渣；在医疗上已有商用等离子体设备用于手术刀具的杀菌；而在科学研究方面等离子体更已成为重要的工具，如纳米碳管的成长，微机电的研发等等。
为了对材料的表面赋予功能性，目前市面上的等离子体改性流程多为先进行等离子体处理，后通惰性气体保护中浸置于改性溶液中接枝。这种方式需要较长的接枝时间，或较高的接枝温度，整体过程较为繁索，常因为接枝条件中参数设置不恰当，而造成效果不佳。
发明内容
为克服现有技术存在缺陷，本发明公开了一种用于织物、无纺布与多孔性薄膜的等离子改性方法及系统。
本发明所述用于织物、无纺布与多孔性薄膜的等离子改性方法，包括如下步骤:
S1.将要处理的材料浸泡在接枝液体中,浸泡时间不小于30秒；浸泡后使用滚压机对材料进行滚压挤出多余液体；
S2.将处理后的材料放入等离子设备进行等离子处理；
S3.处理后的材料在水中并以高周波震动方式进行清洗，所述高周波为频率大于100KHZ的振动波。

优选的，所述接枝液体为包含官能基的液体。
优选的，所述接枝液体为羧基型、环氧型、恶唑啉型、烯基、胺基型、酸酐型、羟基型、钛酸酯型、硅烷型、肽基酰亚胺型和异氰酸酯型中的任意一种或一种以上所配制的溶液。
优选的，等离子改性中通入的气体为氧气或氩气或大气。
优选的，所述步骤S3中，高周波震动方式替换为皂液清洗。
本发明还公开了一种用于织物、无纺布与多孔性薄膜的等离子改性系统装置，包括浸泡接枝液容器、滚压机、烘干装置、等离子枪及高周波清洗池。
优选的，所述高周波清洗池替换为皂液清洗池。
采用本发明所述等离子改性方法及系统，在用于对织物或多孔性薄膜的处理过程中，采用浸渍滚压后，再进行等离子体处理，大幅增加了官能基团数量，不仅改性效果优于传统工艺，而且接枝反应时间大幅度缩短。

具体实施方式
下面对本发明的具体实施方式作进一步的详细说明。
为了使本发明的目的、技术方案及优点更加清楚明白，下面结合具体实施方式对本发明作进一步的详细描述，但不应将此理解为本发明上述主题的范围仅限于下述实施例。在不脱离本发明上述技术思想情况下，根据本领域普通技术知识和惯用手段，做出各种替换和变更，均应包括在本发明的范围内。
本发明所述用于织物与多孔性薄膜的等离子改性方法，包括如下步骤:
S1.将要处理的材料浸泡在接枝液体中,浸泡时间不小于30秒；浸泡后使用滚压机对材料进行滚压挤出多余液体；
S2.将处理后的材料放入等离子设备进行等离子处理；
S3.处理后的材料在水中并以高周波震动方式进行清洗，所述高周波为频率大于100KHZ的振动波。
本发明所述等离子改性方法可以采用如图2所示的等离子改性系统实现，包括浸泡接枝液容器、滚压机、烘干装置、等离子枪及高周波清洗池。
所述接枝液体可以为羧酸基型、环氧型、恶唑啉型、烯基、胺基型、酸酐型、羟基型、钛酸酯型、硅烷型、肽基酰亚胺型和异氰酸酯型中的任意一种或一种以上所配制的溶液。
羧基型为如丙烯酸和丁烯二酸等含有羧基的化合物溶液；环氧基型和烯基为含有环氧基或烯基的化合物如双丙烯季胺盐溶液。恶唑啉基型如2,2′-(1,3--亚苯基)-二恶唑啉溶液，胺基型如乙二胺、二乙醇胺、三乙四胺、六次甲基四胺、四乙五胺等，酸酐型如马来酸酐溶液，羟基型如乙二醇溶液，钛酸酯型如钛酸四丁酯溶液，硅烷型如硅烷偶联剂溶液，肽基酰亚胺型如酰亚胺-二肽溶液溶液异氰酸酯型如MDI、HDI、PDI、TDI等溶于甲苯后的溶液。
具体的实施步骤如下：
首先将要处理的材料浸泡在装有接枝液体的浸泡接枝液容器中；浸泡后使用滚压机对材料进行滚压挤出多余液体；
将处理后的材料利用等离子枪进行等离子处理；处理后的材料在高周波清洗池中以高周波震动方式进行清洗。
以下给出本发明的多个具体实施例。
实施例1：将聚丙烯无纺布浸泡在双丙烯基季铵盐溶液中,溶液质量浓度分别为5％与10％,浸泡10分钟后,将聚丙烯无纺布取出,以滚压机滚压挤出多余液体,滚压可以在保持无纺布平整的同时,相对甩干和风干操作,滚压挤水使无纺布中溶液分布均匀,且能保持无纺布中溶液重量维持在聚丙烯无纺布自重的1.5倍以上,能够在后续作业中提供足够的原子基团。
滚压后进行等离子体辐照,辐照时间为5分钟；辐照后将无纺布放入浸泡接枝液容器进行接枝改性,接枝改性后再将无纺布进行超声波清洗。
接枝改性后的无纺布提高了的抗菌性与亲水性，并由引入的羧酸机团和过氧化物数量得知氧气等离子处理效果要优于氩气等离子处理。
相对传统的做法是先经过等离子体处理后，再与接枝液进行反应，反应时间1小时，传统工艺需要通氮气来防止经等离子活化后的样品与空气的氧气反应，之后再经过净洗与烘干。
而本发明新工艺则是先经过浸渍于接枝液中，经过滚压机将多余液体去除后，再进行通氩气和氮气的等离子体处理、清洗及烘干；本发明不仅改性效果优于传统工艺，而且接枝反应时间大幅度缩短。
等离子处理完成后，将无纺布进行高周波清洗，具体方式为将无纺布展开浸泡在常温水中，水箱侧壁的高周波发生器产生100KHZ以上的高周波，使无纺布在振动情况下去除未接枝上去的多余化学分子。也可以采用皂液清洗方式进行，去除多余化学分子。
等离子处理过程中，PP与双丙烯季胺盐可能发生的两种化学反应式如下式：
PP和双丙烯基季铵盐通过本发明所述的等离子工艺后，PP无纺布上可形成过氧化物、羧基或羟基等官能基。如图2所示，在步骤S2中可能产生以下两种反应：(1)PP经等离子工艺后所产生的官能基与双丙烯基季铵盐的CH2＝CH(π键)反应生成CH2-CH。(2)或与双丙烯基季铵盐的环氧乙烷环反应形成-C-(C＝O)-O。
表一为分别通入氩气与氧气进行等离子体处理后的聚丙烯无纺布采用传统方法和本发明处理后样品的性能，其中季铵化合物水溶液浓度为10wt％，可以看到由于氧气等离子处理引入了更多的过氧化物和羧酸机团，因此氧气等离子体效果优于氩气等离子体。
表一测量了通氩气和氧气等离子体处理后的水接触角，接触角变小说明材料的亲水性增加，而本发明的效果又优于传统工艺之效果，说明本发明改性效果较好，能引入更多的自由基或离子。
表二为本发明与传统工艺在抗菌试验中的比较结果，可以看到无论是采用5％或是10％浓度的季铵化合物，本发明抗菌效果均优于传统工艺。
实施例2
分别以新旧两种方式等离子活化处理聚丙烯无纺布(真空下通氨气)，表面并接枝20wt％丙烯酸水溶液。
本发明的新方法中无接枝时间，传统工艺的接枝时间为3小时，温度为25摄氏度。
分别经等离子处理完成后，将无纺布进行高周波清洗，具体方式为将无纺布展开浸泡在常温水中，水箱侧壁的高周波发生器产生100KHZ以上的高周波，使无纺布在振动情况下去除未接枝上去的附着的多余化学分子。以滚压机滚压挤出多余液体,滚压可以在保持无纺布平整的同时,相对甩干和风干操作,滚压挤水使无纺布中溶液分布均匀,且能保持无纺布中溶液重量维持在聚丙烯无纺布自重的1.2倍以上,能够在后续作业中提供足够的原子基团。
改性后的聚丙烯无纺布所具有的羧酸官能基来自于丙烯酸，羧酸官能基可以与盐基性染料进行反应而达到上色的效果，改善其亲水性及染色性质，来提升聚丙烯无纺布在产业上的应用。
表三为本实施例中新旧两种方法对不同颜色燃料上色的K/S值。K/S值表示染色深度。即利用Kubelka-Munk染色深度方程在被测物体的吸收系数K和散射系数S之间建立的函数。通过计算得到的K/S值越大,固体试样表面颜色越深,即有色物质浓度越高,染料染色性能越好。
由表三结果得知，未经等离子工艺的聚丙烯无纺布，由于没有官能基，无法和盐基性形成离子结合，以致无法上色。经过等离子处理后，可以使聚丙烯无纺布具有官能基，可以与盐基性染料形成离子键结，达到上色的效果。表三表明本发明的等离子工艺的上色深度较传统工艺高，以及有较好的亲水性。
实施例3
分别以新旧两种方式等离子活化处理聚乙烯多孔膜在真空下通氧气，表面并接枝20wt％丁烯二酸水溶液。
本发明新方法无接枝时间，传统工艺的接枝时间为3小时，温度为25摄氏度。
本发明以滚压机滚压挤出多余液体,滚压可以在保持无纺布平整的同时,相对甩干和风干操作,滚压挤水使无纺布中溶液分布均匀,且能保持无纺布中溶液重量维持在聚乙烯多孔膜自重的1.1倍以上,能够在后续作业中提供足够的原子基团。等离子处理完成后，将聚乙烯多孔膜进行高周波清洗，具体方式为将无纺布展开浸泡在常温水中，水箱侧壁的高周波发生器产生100KHZ以上的高周波，使无纺布在振动情况下去除未接枝上去的附着的多余化学分子。
本实施例对染色结果分析如表四
由表四结果得知，未经等离子工艺的聚乙烯多孔膜，仍然可以达到上色的效果，但上色深度比有经过等离子工艺的差，并且本发明等离子工艺的上色深度与亲水性都优于传统工艺。
实施例4
分别以新旧两种方式进行大气等离子活化处理聚对苯二甲酸乙二醇酯织物，接枝20wt％酒石酸水溶液。
本发明新方法无接枝时间，传统工艺的接枝时间为1小时，温度为25摄氏度。
本发明以滚压机滚压挤出多余液体,滚压可以在保持无纺布平整的同时,相对甩干和风干操作,滚压挤水使无纺布中溶液分布均匀,且能保持织物中溶液重量维持在聚对苯二甲酸乙二醇酯织物自重的1.2倍以上,能够在后续作业中提供足够的原子基团。大气等离子处理完成后，将对苯二甲酸乙二醇酯织物在高温气蒸烘箱进行160℃高温蒸处3分钟，然后织物再以皂液清洗后浸泡在常温清水中进行洗涤去除未接枝上去的附着的多余化学分子。
本实施例对染色结果分析如表五
由表五结果得知，未经等离子工艺的聚对苯二甲酸乙二醇酯织物，仍然可以达到上色的效果，以分散性染料对聚对苯二甲酸乙二醇酯织物织物进行染色乃常规知识，但上色深度比有经过大气等离子工艺的差，并且本发明等离子工艺的上色深度与亲水性都优于传统工艺。
实施例5
分别以新旧两种方式进行等离子活化处理聚酰胺织物(真空下通氧气)，接枝15wt％乙二胺水溶液。
本发明新方法无接枝时间，传统工艺的接枝时间为1小时，温度为25摄氏度。
本发明以滚压机滚压挤出多余液体,滚压可以在保持无纺布平整的同时,相对甩干和风干操作,滚压挤水使无纺布中溶液分布均匀,且能保持织物中溶液重量维持在聚对苯二甲酸乙二醇酯织物自重的1.2倍以上,能够在后续作业中提供足够的原子基团。大气等离子处理完成后，将聚酰胺织物在高温气蒸烘箱进行130℃高温蒸处3分钟，然后织物再以皂液清洗，然后织物再以皂液清洗后浸泡在常温清水中进行洗涤去除未接枝上去的附着的多余化学分子。
本实施例对染色结果分析如表六
由表六结果得知，未经等离子工艺的聚酰胺织物，仍然可以达到以酸性染料上色的效果，以酸性染料对聚酰胺织物进行染色乃常规知识，但上色深度比有经过等离子工艺的差，并且本发明等离子工艺的上色深度与亲水性都优于传统工艺。
采用本发明所述等离子改性方法及系统，在用于对织物或多孔性薄膜的处理过程中，采用浸渍滚压后，再进行等离子体处理，大幅增加了官能基团数量，不仅改性效果优于传统工艺，而且接枝反应时间大幅度缩短。
前文所述的为本发明的各个优选实施例，各个优选实施例中的优选实施方式如果不是明显自相矛盾或以某一优选实施方式为前提，各个优选实施方式都可以任意叠加组合使用，所述实施例以及实施例中的具体参数仅是为了清楚表述发明人的发明验证过程，并非用以限制本发明的专利保护范围，本发明的专利保护范围仍然以其权利要求书为准，凡是运用本发明的说明书内容所作的等同结构变化，同理均应包含在本发明的保护范围内。
