一种防撕裂布及其制备方法
技术领域
本发明涉及纺织材料技术领域,尤其涉及一种防撕裂布及其制备方法。
背景技术
帐篷是撑在地上遮蔽风雨﹑日光并供临时居住的棚子,多用帆布做成,连同支撑用的部件可随时拆下转移。帐篷是以部件的方式携带,到达现场后才加以组装,由于其构造简单,展收方便,所以帐篷不仅应用于军事装备,还广泛应用于野外考察、露营、勘探、施工、救灾、防汛等领域。
面料作为帐篷的主要组成部分,承载着主要的遮风避雨功能。然而,使用过程中的拉拽、折叠等会造成面料的损坏,使得帐篷无法反复使用。因此,亟需一种抗撕裂性能优异的面料以实现帐篷的反复使用。
发明内容
本发明的目的在于提供一种防撕裂布及其制备方法,本发明提供的防撕裂布抗撕裂性能优异,可反复使用。
为了实现上述发明目的,本发明提供了以下技术方案:
本发明提供了一种防撕裂布,包括基布层和连接于所述基布层表面的防撕裂层;
所述防撕裂层由经纱、纬纱和加强筋织造而成,所述加强筋分别沿径向和纬向间隔设置;
所述加强筋包括碳纤维和包覆于所述碳纤维表面的锦纶长丝。
优选地,所述经纱和纬纱的原料独立地为涤纶、维纶和氨纶中的一种或几种。
优选地,所述加强筋在径向和纬向的间隔距离独立地为0.5~2cm。
优选地,所述加强筋中碳纤维的质量含量为30~50%,锦纶长丝的质量含量为50~70%。
优选地,所述基布层的原料包括棉纤维、粘胶纤维、涤纶和锦纶中的一种或几种。
优选地,所述基布层和防撕裂层的连接方式包括粘合剂粘合或缝纫线连接。
优选地,所述基布层的厚度为0.5~0.8mm,所述防撕裂层的厚度为1~1.5mm。
本发明提供了上述技术方案所述防撕裂布的制备方法,包括:
(1)将加强筋分别沿径向和纬向间隔设置后进行织造,得到防撕裂层;
(2)将基布层和所述步骤(1)得到的防撕裂层进行连接,得到防撕裂布。
优选地,所述步骤(2)中连接所用材料包括粘合剂或缝纫。
本发明提供了一种防撕裂布,包括基布层和连接于所述基布层表面的防撕裂层;所述防撕裂层由经纱、纬纱和加强筋织造而成,所述加强筋分别沿径向和纬向间隔设置;所述加强筋包括碳纤维和包覆于所述碳纤维表面的锦纶长丝。本发明通过在碳纤维表面包覆锦纶长丝制成加强筋,再将加强筋与经纱、纬纱间隔设置,进而制成防撕裂层,再与基布层结合,从而得到了一种抗撕裂性能优异的防撕裂布。实施例的结果显示,本发明提供的防撕裂布的撕裂强力可达75N。
具体实施方式

(2)经纬纱均采用涤纶,在织机上进行织造,得到基布层;
(3)先分别沿径向和纬向每隔0.8cm设置步骤(1)得到的加强筋,然后采用平纹组织进行织造,得到防撕裂布;
(4)用粘合剂粘合步骤(2)得到的基布层和步骤(3)得到的防撕裂层,得到防撕裂布。
按照GB/T 3917.1—2009《纺织品织物撕破性能第1部分:冲击摆锤法撕破强力的测定》进行测试,测得本实施例制备的防撕裂布的撕裂强力为75N。

制备过程:
(1)以碳纤维为芯纱,通过环锭纺将两根锦纶长丝以相反的捻向包覆于碳纤维表面,得到加强筋;
(2)经纬纱均采用粘胶纤维,在织机上进行织造,得到基布层;
(3)先分别沿径向和纬向每隔1.5cm设置步骤(1)得到的加强筋,然后采用平纹组织进行织造,得到防撕裂布;
(4)用粘合剂粘合步骤(2)得到的基布层和步骤(3)得到的防撕裂层,得到防撕裂布。
按照GB/T 3917.1—2009《纺织品织物撕破性能第1部分:冲击摆锤法撕破强力的测定》进行测试,测得本实施例制备的防撕裂布的撕裂强力为72N。
由以上实施例可以看出,本发明提供的防撕裂布具有优异的抗撕裂性能,撕裂强力可达75N。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
