为研究经编长效蚊帐在使用过程中的顶破性能，采用不同组织与材料编织经编网眼织物，对这些织物进行顶破性能测试分析。对比各试样顶破强力与顶破伸长的差异，观察织物破裂时结构的瞬间变化情况，以及研究在试验中织物受力与形变的关系，并建立了一套经编织物顶破性能的观察系统。结果表明：涤纶和聚乙烯经编网眼织物的力学性能有明显不同；相同材料的网眼织物，纱线线密度越大、织物克质量越大，抗顶破性能越好；六角网眼结构比四角网眼结构抗顶破性能好，但四角网眼结构能在织物破裂后更好地阻碍织物的脱散。
為研究經編長效蚊帳在使用過程中的頂破性能，採用不同組織與材料編織經編網眼織物，對這些織物進行頂破性能測試分析。對比各試樣頂破彊力與頂破伸長的差異，觀察織物破裂時結構的瞬間變化情況，以及研究在試驗中織物受力與形變的關繫，併建立瞭一套經編織物頂破性能的觀察繫統。結果錶明：滌綸和聚乙烯經編網眼織物的力學性能有明顯不同；相同材料的網眼織物，紗線線密度越大、織物剋質量越大，抗頂破性能越好；六角網眼結構比四角網眼結構抗頂破性能好，但四角網眼結構能在織物破裂後更好地阻礙織物的脫散。

In order to study the bursting properties of warp knitted long lasting mosquito-proof net,several warp fabrics with different stitches and fibers were knitted and tested in this paper. Difference between the bursting prop-erties of those fabrics such as bursting strength and elongation were compared , and the fabric changes at the burst-ing break point were observed, the relationship between stress and strain were analyzed, observing systems of the warp fabric’s bursting behaviors were established. The results show that there is obvious difference between the bursting properties of polyester fibre and PE fabrics;under the conditions of the same materials,the density of yarn is bigger, and the gram weight of fabric is larger, then the bursting strength of the fabric is bigger; fabric has good bursting properties with hexagonal mesh structure, but fabrics with four corners mesh structure can resist lad-dering better.
