Description

一种防划伤辐射降温纤维
技术领域
本发明涉及纺织产品结构技术领域，特别涉及一种防划伤辐射降温纤维。
背景技术
镀银纤维作为一种高性能功能纤维，其独特的抗菌除臭、防电磁波辐射、抗静电、调节体温等功能受人瞩目。其在应用当中，往往防辐射效果表现不佳，同质化严重，造成这一现象有一个方面不容忽视：在纺织的过程中，由于镀银纤维要通过针织机或梭织机进行作业，镀银纤维在通过钩针或棕丝等过程中，极易被这些器件划伤银纤维表面的镀银层，进而导致镀银纤维的导电率下降，影响织物的电磁屏蔽效果，从而影响镀银纤维织物的使用寿命和效果。
现有技术中：
(1)对比专利名称
一种新型镀银纤维
申请公布号:CN 103590158 A
对比发明采用在银层与尼龙纤维之间形成有结合层，所述银层表面涂覆有防止银层在织造过程中被划伤的防护层。但其保护膜仅仅有保护内部的功能，无辐射降温功能，从而也无法增强舒适性。其采用的所述防护层为有机硅液体蜡或有机氟液体蜡中的一种或几种，与本专利有显著的区别，从而也造成了功能差异。
(2)对比专利名称
一种防辐射抗菌面料及其制备方法
授权公告号:CN 104957815 B
对比发明专利采用电解方法将银设置在载体表面的纤维作为经线，纬丝为经抗菌整理液处理的抗菌纤维，防辐射抗菌面料结构简单、成本低廉、原料来源方法、抗菌效果非常优异、抗菌时间长，具有广谱抗菌作用。但该专利采用了镀银纤维，但未对该层进行保护，也无法实现被动式辐射降温功能。
因此，针对现有技术的不足，有必要提出一种新的技术方案。
发明内容
本发明的主要目的是提出一种防划伤辐射降温纤维，旨在使其具有防止在生产时被划伤、损害的功能，同时又能被动式对外辐射8-13μm的红外，产生降温功能，增强穿着舒适性。
为实现上述目的，本发明提出的一种防划伤辐射降温纤维，包括纤维本体，在纤维本体的表面设置有镀银层，在镀银层的表面设置有一辐射降温保护层。
优选地，所述辐射降温保护层是由无机非金属微米球和高分子基体组成的透明薄膜层。
优选地，所述无机非金属微米球为实心球体或中空球体，且所述无机非金属微米球为黏土、石墨烯、硅藻土、SiS2和SiO2中的一种或多种。
优选地，所述无机非金属微米球的堆积密度为30％～60％。优选地，所述高分子基体为PS、PP、PE、PBT、PC、PVC、TPX、PET、ABS以及PMMA中的一种或多种。
优选地，所述纤维本体为棉、毛、丝、麻、涤纶、锦纶、腈纶、维纶、丙纶、氯纶、氨纶、芳纶中的一种或几种的结合。
优选地，所述镀银层的厚度为10-300nm。
优选地，所述辐射降温保护层的厚度为5-1000μm。
优选地，所述无机非金属微米球的粒径为2～80μm。
本发明技术方案通过采用在原有镀银纤维基础上，增加了高分子结构的辐射降温保护层，有效地保护内部结构加工和使用过程不易损害，增强了多功能效果的持续性和耐用性，同时又能被动式对外辐射8-13μm的红外，产生降温功能，增强穿着舒适性。

图1为本发明的切面示意图；
图2为本发明的横截面示意图；
本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
本发明提出一种防划伤辐射降温纤维。

本发明技术方案通过采用在原有镀银纤维基础上，增加了高分子结构的辐射降温保护层3，有效地保护内部结构加工和使用过程不易损害，增强了多功能效果的持续性和耐用性，同时又能被动式对外辐射8-13μm的红外，产生降温功能，增强穿着舒适性。
在本发明实施例中，无机非金属微米球4为实心球体或中空球体，且无机非金属微米球4为黏土、石墨烯、硅藻土、SiS2和SiO2中的一种或多种。
在本发明实施例中，高分子基体5为PS、PP、PE、PBT、PC、PVC、TPX、PET以及PMMA中的一种或多种。高分子基体5具体地包括但不限于上述的透明高分子。

该防划伤辐射降温纤维，可以应用于纺织、生物、医药、建筑、环保、军事等领域。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
