摘要:本文对比分析了国内外蚊帐网布质量要求存在的差异,并测试典型样品的重要物理机械性能,探讨了纱线、网孔形状和组织结构等对网布尺寸稳定性和顶破性能的影响并着重对比分析不同顶破性能测试方法结果的差异。研究发现,液压胀破法测试结果稳定性更好,实验误差较小。相关企业既做内销又做外销时,应注意产品在国内外的不同质量要求,科学应对,降低成本同时也合理规避贸易风险。

The Study on Physico-mechanical Properties of Mosquito Netting Based on Interpretation of Related Domestic and International Testing Standards
Abstract: In this paper, the differences between domestic and overseas quality requirements and standards concerning mosquito netting and nets in terms of physical properties are discussed in detail. Based on which, some typical mosquito net samples are carefully selected and tested according to the domestic and WHO standards to compare their results, and the influences of type of yarn, eyelet shape and fabric structure on nettings physical properties are discussed. Meanwhile, the bursting properties of fabrics are tested with both hydraulic method and steel ball method. It was found that the results of hydraulic method were more stable with lower fluctuation.
Key words: mosquito netting; physico-mechanical properties; standard; dimensional stability; bursting strength
1 简介
防蚊蚊帐是一种被世界卫生组织(WHO)和国际粮农组织(GMP)联合推荐的最有效的 3 种预防疟疾的基本方法之一。目前,蚊帐及蚊帐网布的生产主要集中在中国、孟加拉、印度、越南等亚洲国家,以及部分美洲国家等。我国的蚊帐网布产业基地主要分布在浙江、江苏、福建、广东等纺织强省。产品出口与内销旺盛,其中驱蚊蚊帐主要出口非洲各个国家。然而,国内外对蚊帐网布的外在质量及物理性能的要求不尽相同。
蚊帐网布面料可按款式、材质、网孔形状、组织结构等进行分类。涤纶广泛易得,工艺成熟,成本适宜,织造效率高,是最常用的蚊帐网布原材料;形成蚊帐网布最常见的方法是通过针织经编织造,通过不同垫纱方法,使相邻的纵行在某些横列失去联系,形成网孔,常见的结构有菱形网孔、六角网孔和方格网孔等,部分高档蚊帐采用经编提花组织。……
