Description
技术领域
本发明涉及皮革技术领域,更具体的说是涉及一种天然纤维增强抑菌、排汗、透湿四面弹力皮革。
背景技术
目前人造革领域材料抑菌功能，主要是通过银离子或者铜离子等化学抑菌助剂来实现，这类化学助剂需要严格控制用量，如果是用过量会对人的健康造成危害，而且在日常使用中随着磨损和清洗的次数增加，抑菌功能会逐渐的减弱甚至丧失。
发明内容
有鉴于此，本发明提供了一种具有亲肤、透气、透湿以及抑菌等功能的天然纤维增强抑菌、排汗、透湿四面弹力皮革。
为实现上述目的，本发明提供如下技术方案：
一种天然纤维增强抑菌、排汗、透湿四面弹力皮革，其特征在于，该皮革由牛皮纤维四面弹针织布、湿法贝斯层和干法贴面层组成；其中，所述牛皮纤维四面弹针织布100-200份；所述湿法贝斯层200-300份；所述干法贴面层300-400份。
优选的，在上述一种天然纤维增强抑菌、排汗、透湿四面弹力皮革中，所述湿法贝斯层包含有柔软聚氨酯树脂，超软聚氨酯树脂，二甲基甲酰胺，泡孔调节剂，色浆，苎麻纤维粉末，甲壳质粉，分散剂和防水助剂。
优选的，在上述一种天然纤维增强抑菌、排汗、透湿四面弹力皮革中，所述干法贴面层由由面层浆料和底料组成；其中，所述面层浆料包含有二甲基甲酰胺，色片，柔软贴面聚氨酯树脂；底层浆料包含有二甲基甲酰胺，色片，柔软贴面聚氨酯树脂。
经由上述的技术方案可知，与现有技术相比，本发明的皮革产品的亲肤、透气、透湿以及抑菌功能，都是对传统皮革的革命性突破，解决了传统人造革不能贴身服用或者是贴身穿不舒服的痛点，极大增加了皮革的应用范围和消费者的穿着舒适性；利用牛皮纤维这种天然有机纤维完美的替代了传统银离子、铜离子等化学抑菌助剂，实现了面料天然抑菌功能，结合皮革透气涂层工艺制备该产品，极大提高了传统皮革的亲肤、透气及抑菌功能，扩大了皮革的应用范围。
具体实施方式
下面将结合本发明实施例，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明融合了纺织和人造革的生产工艺，利用传统牛皮生产过程中产生的边角废料，通过一系列回收工序(选料、浸渍、脱脂、开松、除杂)将废料变成牛皮纤维，再将牛皮纤维和纯棉纤维混纺，制备成胶原蛋白纤维纱线。胶原蛋白纤维纱线通过针织织造工艺制成达到制革要求的革基布，最终通过皮革湿法工艺和涂层透气工艺制成可以有多种用途的人造革面料，四面弹力，触感舒适,柔软细腻,透气性好，排汗、透湿，并具有天然的抗菌、防霉功能。本发明涉及纺织和人造革领域，是人造革领域的一项重大突破。
