Description

毛纺品的一种超临界二氧化碳流体丝光处理方法 技术领域
本发明涉及纺织染整工艺当中的丝光工艺，特别涉及毛纺品的一种超临界二氧化碳流体丝光处理方法，属纺织染整加工技术领域。
背景技术
丝光羊毛是羊毛经过纺织品染整工艺当中的丝光工艺，对羊毛制品进行的处理，处理后的羊毛具有线光泽和手感，俗称为丝光羊毛。目前国内一般是将羊毛经BasolanDC氯化或蛋白酶处理，破坏、剥去羊毛表层的毛鳞片，减少羊毛的顺向与逆向运动时摩擦系数之差异。丝光处理过的羊毛线，可以纯羊毛纺织，也可混纺。主要特性是防缩水、可机洗、抗起球。但传统丝光工艺也有一定的缺陷，氯化法丝光产生的可吸附有机氯化物毒性很高。蛋白酶减量法中，蛋白酶单独对羊毛处理效果并不好，应用蛋白酶对羊毛进行改性处理即丝光细化，还必须先对羊毛进行氧化等前处理，不仅增加成本，而且使工艺更为复杂。
超临界二氧化碳流体技术具有环保和节能的特点，普遍应用于食品，医药，染色，分离过程和酶催化等领域。所使用的二氧化碳安全可靠，价格便宜，方便易得，无毒无害，不可燃，还可循环再利用。此技术目前在纺织加工领域主要应用于无水染色方面，由于其染色的高效性和节能环保等特点，受到了越来越多的关注。而超临界二氧化碳流体在毛纺品的丝光处理方面鲜有人研究，应当受到我们的重视。
发明内容
为解决上述技术问题，本发明的目的是提供了一种毛纺品的超临界二氧化 碳流体丝光处理方法，解决传统方法高能耗、高排放和高污染等问题，发明提供的处理方法操作方便、工艺简单，能耗低，具有生态环保、节能减排等特点。
本发明提供了一种毛纺品的超临界二氧化碳流体丝光处理方法：
采用超临界二氧化碳流体或亚临界二氧化碳流体取代传统水浴作为流体介质，或向所述流体介质中添加一定含量的辅助成分，在一定条件下实现对毛纺品的无水干态丝光处理。
进一步地，所述的辅助成分为K 2S 2O 8、NaClO、Na 2O 2、NaClO 2、H 2O 2、NaBO 3·4H 2O、KMnO 4、CH 3COOOH及其盐类中的一种或它们的任意组合。
进一步地，所述的辅助成分为Na 2SO 3、Na 2S 2O 3、Na 2S 2O 4中的一种或它们的任意组合。
进一步地，所述的辅助成分为O 3类氧化性气体。
进一步地，所述的辅助成分为树脂类高分子。
进一步地，所述的一定条件，是指丝光压力为8Mpa～50Mpa，丝光温度控制在80℃～120℃，丝光时间为30min～180min。
进一步地，所述的毛纺品为全毛制品或与其他种类纤维的混纺及交织品；或者为散毛、毛条、毛线或其他制造形式产品。
进一步地，所述的无水干态指丝光处理后毛纺品的含水率低于其公定回潮率。
进一步地，所述公定回潮率为15-16％。
进一步地，本发明提供了一种毛纺品的超临界二氧化碳流体丝光处理方法，包括以下步骤：
(1)将待处理羊毛毛条均匀地缠在多孔空心轴外侧；
(2)将步骤(1)的装载有毛纺品的多孔轴置于丝光处理腔内及流体分布腔体上端，并与倒置呈喇叭形的流体导流器连通，且将丝光处理腔、多孔轴与 其下端流体分布腔体形成丝光组合体；
(3)将上述含有毛纺品的多孔轴的丝光组合体置于超临界二氧化流体处理装置中，密闭系统后在一定条件下，采用流体的强制性循环对多孔轴上毛纺品进行压差丝光处理。
进一步地，所述的将毛纺品按一定方式装载于多孔的空心轴上，是指可以采用卷绕方式将毛纺品置于多孔空心轴外围，或将毛纺品卷绕后置于多孔空心轴内部。
进一步地，所述的多孔的空心轴，其上端封闭，下端开口，并与倒置呈喇叭形的流体导流器相连接。
进一步地，所述丝光组合体中流体导流器下端的喇叭口处，设置有多孔的流体分布器。
进一步地，所述的一定条件，是指丝光压力为8Mpa～50Mpa，丝光温度控制在80℃～120℃，丝光时间为30min～180min。
本发明的技术方案中，超临界二氧化碳流体能进入到羊毛的鳞片层内部并使其溶胀或辅助溶胀，在流体循环流动的过程中，羊毛的鳞片层逐渐被破坏或实现包埋，达到丝光防缩整理的目的。因其无需使用其它大量化学试剂，所需处理温度低，时间短，因而对纤维的损伤更小。
借由上述方案，本发明至少具有以下优点：
本发明的应用不但可以显著缩短纺织品的丝光防缩处理时间，而且可以解决传统丝光前处理加工过程中的高能耗、高排放、高污染等问题。本发明方法工艺简单，操作方便简洁，反应温和，在丝光处理过程中对纤维损伤小，避免了传统丝光工艺中大量水、热和含氯溶液的应用，且不会影响人体健康，具有高效、绿色、环保等特点。
