一种防黏身单向导湿织物及加工方法
相关申请的交叉引用
本申请要求于2021年12月22日提交中国专利局，申请号为202111583652.9，发明名称为“一种防黏身单向导湿织物及加工方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明属于纺织技术领域，尤其涉及一种防黏身单向导湿织物及加工方法。
背景技术
功能服装面料因具有良好的功能效果，在体育运动服装、体能训练服装等领域具有广泛的应用前景。单向导湿功能服装材料具有吸湿快干特性，深受服装设计者和消费者喜爱和选择，市场前景良好。单向导湿功能通常是指人体因运动出汗，汗液通过织物有内层快速传递到外层，并沿外层纱线中迅速扩散，从而使汗液得以快速蒸发。实现单向导湿功能的面料方法通常有两种方法：一是采用防水涂层方法，在织物内层表面，通过印花涂层的方法在织物内层表面形成一定图案的防水涂层，另外一面通过亲水整理，利用整理剂整理的方式，在织物内表面和外表面形成吸水导水能力的差异，实现织物的单向导湿功能；二是采用双层织物结构，将具有不同性能的纱线材料，通过织物结构设计，形成具有双层结构的织物，利用内层和外层性能上的差异，并通过整理剂整理的方式，实现织物的单向导湿功能。
当人体进行大运动量运动时，或在炎热和高温环境条件下，人体皮肤表面会大量汗量，同时伴有油脂产生，从而造成服装材料与皮肤表面之间发生黏贴现象，使人体产生不舒适感。根据现有文献和相关专利显示，目前所有研究和专利仅仅考虑将汗液通过单向导湿，将汗液传导到织物外层，不能实现防黏身的功效。
从织物舒适性理论和织物液体传输理论上讲，实现织物单向导湿和防黏身功能集合一体，织物设计必须满足：(1)如何快速将皮肤表面的汗液排出到织物表面，使皮肤表面快速干燥；(2)织物内表面与皮肤表面的接触状态和性质(表面张力)。以双层织物为例，通常采用织物内层纱线为疏水性纤维材料，织物外层纱线为亲水性纤维材料，通过外层纤维材料与内层纤维材料对水的吸附和传到能力的差异特征，实现汗液从织物内层传输到织物外层。根据液体在多孔材料的传输理论，液体通过多孔结构传递的数量与速度，不仅与材料的表面张力有关，还取决于多孔结构的孔径及其分布。根据差动毛细效应原理，针对双层织物来讲，实现快速汗液从织物内层向织物外层的快速传导，不仅仅是内外层纤维材料为疏水/亲水搭配，还有内外层材料的表面张力具体数值、内层表面疏水/亲水材料的分布状态、内层纤维之间的孔洞尺寸与外层纤维之间孔洞尺寸大小以及形成的尺寸配置结构等影响因素，这些因素均是独立的影响因素，并且同时满足上述因素的要求，才能实现单向导湿的目的。更为重要的是，由于内层材料为疏水性纤维，汗液要想通过内层材料，快速传导到外层并扩散，首先要克服内层材料对水的疏水性，克服液体与内层材料之间所存在的接触角的影响。疏水性纤维材料与液态水之间要想形成浸润导流，目前通常采用的方法是对疏水性纤维进行亲水性表面整理方法，改变疏水性纤维的表面状态，实现液态水对疏水性纤维的浸润导流，即采用整理剂的方式整理织物，但这种方法耐洗涤效果不好，并且由于使用整理剂需要进行污水处理，不符合环境保护要求。
发明内容

本发明的有益效果为：本发明通过内层纤维的“W”截面设计，改变液体与内层纤维材料的接触状态，结合具有微相分离结构改性长碳链聚酰胺纤维表面张力的特性，克服由于内层纤维疏水性产生的憎水效应，大幅度提高内层纤维的液体沿表面的浸润效果，使汗液能够在疏水性纤维材料表面快速传导；结合内、外层纤维结构参数和性能特征的配置，以及结构设计，形成内外层对液体势能差，进而形成差动毛细效应，实现织物单向导湿和防黏身功能特征。同时，这种内外层纤维性能和结构的配置，使织物无须任何整理剂，即可实现单向导湿效果，避免使用憎水、亲水、柔软整理以及其它整理剂，实现了在整个加工生产过程中良好的环境保护效益，同时大大缩短工艺 流程，工艺容易控制、原材料易得。
附图说明

具体实施方式
通过调整疏水性纤维截面形态，改变液态水在纤维表面的接触状态，使液态水与疏水纤维表面接触形式，由点线接触，改变成特定形状的曲面接触形式，从而增加液态水与纤维之间的相互作用，更为主要的是通过在疏水性材料中，通过增加不同形式的软硬分子链段，对长碳链聚酰胺进行改性，调整疏水性纤维的微相分离结构程度，从而调整疏水纤维表面性能，从而减小液态水在疏水纤维表面的滚动接触角。通过纤维截面形状和表面特性的结合。可以实现在不使用任何整理剂条件下，液态水能够在疏水纤维表面浸润并传导入外层亲水层中，而内层疏水纤维层并不吸收也太水分，并保持干燥状态。此外由于内层直接接触到皮肤表面的汗液，在实现单向导湿功能的基础上，同时具有防黏身的功能效果，内层结构设计成为关键，通过对织物与皮肤表面产生黏贴现象的研究，产生黏贴现象是由于皮肤表面的汗液与皮肤表面的油脂综合作用的结果，汗液和油脂的作用不仅改变了织物的柔韧性、同时改变了织物与皮肤之间的表面张力。
通过织物内层纤维材料的选择，以及纤维细度，特别是纤维截面形态的设计，使织物与皮肤表面之间形成一个气-液平衡界面，结合内外层纤维配置和织物结构特征的快速蒸发特征，是解决织物黏贴现象的重要方式。本发明将纤维截面形状和材料性能相结合，实现一种防黏身单向导湿织物及加工方法。
为了更好的理解本发明，下面结合图和实施例对本发明做进一步说明，但本发明的实施方式不限于此。图1为本发明中的改性长碳链聚酰胺纤维“W”形横截面电子显微镜照片。
