Description

一种高强度高透气面料
技术领域
本发明属于纺织生产领域，具体涉及一种高强度高透气面料。
背景技术
面料是用来制作服装的主要材料。作为服装三要素之一，面料不仅可以诠释服装的风格和特性，而且直接左右着服装的色彩、造型的表现效果。同时，根据不同的使用场所，对面料的力学性能及其化学性能有着不同的要求。
防护服具有良好的透湿性和阻隔性，能有效抵抗酒精、血液、体液、空气粉尘微粒、细菌的渗透，使用安全方便，能具有效保护穿着者免受感染威胁,穿用舒适、手感好、抗拉力强、透气防水、无交叉感染等，但是现有的防护服面料存在着透气透湿不足闷热、生产方式单一等问题，因此设计一种高强度高透气面料很有必要的。
发明内容
本发明的目的在于提供一种高强度高透气面料，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：一种高强度高透气面料，其特征在于：包括高透气胶膜层和增强层，所述高透气胶膜层可设置有聚乙烯多孔透气膜、TPU透气膜、TPU树脂或聚四氟乙烯透气膜，所述高透气胶膜层由胶膜基体树脂、纳米纤维以及相容剂组成，所述纳米纤维的直径为300-800nm，比例为5-15份，以增加其强度，所述纳米纤维材料的熔点高于基体材料10-20℃，所述增强层可设置为透湿性好的纺织物或无纺织物，所述纺织物类型的增强层在织造时，纱线要经与基体材料相容的胶料挂胶处理后再进行织造；所述无纺织物类型的增强层在熔喷时在原料中添加一定比例的透气胶膜材料，以增加两层的粘附力，添加比例为10-50份。
优选的，所述高透气胶膜层由胶膜基体树脂、纳米纤维以及相容剂组成，所述纳米纤维的直径为300-800nm，比例为5-15份，以增加其强度，所述纳米纤维材料的熔点高于基体材料10-20℃。
优选的，所述高透气胶膜层由基体树脂、纳米级短纤维以及相容剂组成，采用流延法制成。
优选的，所述高透气胶膜层也可以由TPU树脂、纳米级长纤维以及相容剂组成，采用造纸的方法制成。
优选的，所述纺织物的透湿性在10000g/㎡·d以上，所述纺织物的密度在150-200根/英寸，且所述纺织物包括但不仅限于棉、毛、竹纤维等本身具有良好透气性的纤维织物，且所述无纺织物包括但不仅限于聚丙烯无纺布。
优选的，所述增强层也可以由打孔材料制成,网状结构可为菱形、矩形、三角形、蜂窝或其他多边形结构，或离散有序无序线段结构增强的材料构成。
本发明的技术效果和优点：该高强度高透气面料，通过将面料整体结构设置成两层或是多层，且设置有高透气胶膜层，实现了面料高透气透湿、不足闷热的功能；再加上高透气胶膜层可设置为聚乙烯多孔透气膜、TPU透气膜、TPU树脂或聚四氟乙烯透气膜，可根据具体的实际需求进行选择，增加了该面料的功能性；同时，高透气胶膜层可由胶膜基体树脂、直径纳米级别的短纤维以及相容剂组成，纳米纤维的直径以300-800nm，比例以5-15份为佳，以增加其强度，纳米纤维材料的熔点高于基体材料10-20℃，采用流延法制成；高透气胶膜也可以由基体树脂、直径纳米级别的长纤维以及相容剂组成，采用造纸的方法制成；通过将增强层设置为不同的网状结构（如菱形、矩形、三角形、蜂窝或其他多边形结构）或离散有序无序线段结构增强的材料构成，来实现高强度，且纺织物类型的增强层在织造时，纱线要经与基体材料相容的胶料挂胶处理后再进行织造；无纺织物类型的增强层在熔喷时在原料中添加一定比例的透气胶膜材料，以增加两层的粘附力，添加比例为10-50份。本发明创新了面料宏观微观结构，解决了防水高透气高透湿性能、优异的物理机械性能难以同时实现的问题；规避了复杂工艺和高成本等问题。

实施例1
如图1所示，增强层采用密集有序的网状结构，高透气胶膜由胶膜基体树脂、纳米级别的短纤维以及相容剂组成，纳米纤维的直径为300nm，比例为10份，以增加其强度，纳米纤维材料的熔点高于基体材料15℃，成形方法采用流延法制成，将高透气胶膜附在增强层用作医用防护的主要面料。
实施例2
如图2和图4所示，增强层采用多边形网状结构或蜂窝结构，纺织物类型的增强层在织造时，纱线要经与基体材料相容的胶料挂胶处理后再进行织造；或无纺织物类型的增强层在熔喷时在原料中添加一定比例的透气胶膜材料，以增加两层的粘附力，添加比例在45份，该面料适合长时间在温度偏高的工作环境中。
