一种复合型结构弹性医用绷带及其制备方法
技术领域
本发明涉及医疗用品技术领域，尤其涉及一种复合型结构弹性医用绷带及其制备方法。
背景技术
绷带在现实生活中用途广泛，不同的伤情运用不同的绷带包扎。目前，在医学领域，如遇到四肢扭伤、软组织损伤、关节肿痛等病症时，常用弹性绷带进行辅助治疗。现在市售常见的弹性绷带有皱纹弹性绷带、氨纶弹性绷带、PBT弹性绷带等。
在公开的中国专利文献中可见诸关于弹性绷带的信息，如专利号为CN207071113U的专利中，提供了一种以棉线作为经线，弹力线作为纬线编织而成，再涂覆一层水凝胶层的弹性绷带。这种弹性绷带只能防止绷带与伤口粘连，吸湿性较差，无法具有抑菌的效果。如专利号为CN204909821U的专利中，提供了一种防尘除菌弹性绷带，虽然保证了防菌杀毒的作用，但缺少能提供强度的结构层，与外部接触时，耐磨性、强度均较弱。上述现有的专利中，缺少将良好透气性、可控弹性变形、抑菌性及亲肤性等特点结合在一起的产品，作为本领域技术人员，亟待开发结构复合型弹性医用绷带。
发明内容
本发明的目的是为了解决现有技术中存在的缺点，而提出的一种复合型结构弹性医用绷带及其制备方法，赋予医用绷带良好的透气性、亲肤性，提高患者使用舒适度，且抗菌效果优良。
为了实现上述目的，本发明采用了如下技术方案：一种复合型结构弹性医用绷带，包括外层和内层，所述外层基于经向长浮长织物组织结构，由预张力氨纶和低弹纱有织布交织而成；所述内层为低克重水刺非织布，所述低克重水刺非织布为改性竹炭纤维。
优选地，所述低克重水刺非织布由天丝和壳聚糖纤维构成。
本发明还提供了一种复合型结构弹性医用绷带的制备方法，包括以下步骤：
步骤一，制备外层：将预张力氨纶和低弹性纱按照配比(5-9)：1，分别制得预张力氨纶经轴和低弹性纱经轴；纬纱采用低弹性纱；基于经向长浮长织物组织结构，将经纬纱交织，获得具有可控变形能力的绷带外层；
步骤二，制备内层：改性竹炭纤维或将天丝和壳聚糖按比例(30-40)：(70-80)在棉箱内混合；散纤维经梳理机形成低克重的纤维网；基于水刺工艺，对纤维网进行预湿、三至五道水刺加工，其最后一道水刺面为贴肤面，再经过压匀烘干，获得贴肤面整洁的绷带内层；
步骤三，内外层复合：采用高温液压机将绷带外层和绷带内层压合，温度145-155℃，压强1-2MPa，时间11-13s；压合过程中确保两层织物平整，从而制成医用绷带。
优选地，所述步骤一中，预张力氨纶的预加张力为0.2-0.3N；低弹性纱为涤纶或锦纶。
优选地，所述步骤二中，竹炭纤维的改性方法如下：
(1)将竹炭纤维加入到其体积5-10倍的乙酸溶液中，经搅拌、过滤、蒸馏水洗涤和烘干；
(2)将纳米二氧化钛、氧化石墨烯放入球磨机中充分混合均匀，然后在真空干燥箱的氮气氛围中处理，将其加入其体积10-15倍的硅烷偶联剂溶液中，进行超声处理，然后加入竹炭纤维，继续整理、过滤，将所得物放入微波装置中处理，取出后将其送入蒸汽室内，然后干燥即可。
本发明具有以下有益效果：本发明的一种复合型结构弹性医用绷带及其制备方法，其外层具有一定的强力和弹性，使得绷带能够具有较大身长变形且变形可控；其内层柔软亲肤，具有一定的抑菌性；复合后的产品，能够保证良好的透气性，提高了使用舒适性，性质稳定，并且对人体无害，更利于康复。
