摘　　要：采用3根直径均为0.03 mm的超细不锈钢丝并线而成的金属丝,在E16拉舍尔经编机上利用两把梳栉一穿一空编织而成的开口经缎菱形网格织物为试样,通过单向拉伸和双向拉伸实验来探讨柔性经编金属网格材料的拉伸性能。结果表明:柔性经编金属网的横向伸长率远大于其纵向伸长率,但纵横向强力相差较小;对于同种材料、同种组织的织物来说,密度越大,拉伸变形越小,但断裂强力无明显变化;同时拉伸速度和加载角度对测试结果有一定的影响。This paper is mainly to study the tensile properties of a flexible warp knitted metal mesh by unidi- rectional and hi-directional tensile test, and the flexible warp knitted metal mesh is diamond-shaped open atlas mesh produced on Raschel El6 warp knitting machine with two bars of one in one out threading mode by using three uhra-fine stainless steel wires plied yarn with diameter of 0.03 ram. The results indicated that the horizontal elongation of the flexible warp metal mesh is much larger than its longitudinal elongation, but the horizontal tensile strength is nearly the same as the longitudinal tensile strength. For the same material and same structure fabrics, the greater density the fabric has, the smaller the tensile defurmation is, but the breaking strength has no signifi- cant change. The tensile speed and loading angle have influences on the test results.
