提高纯涤帐篷布纬向强力的工艺实践

Processing Practice of Improving Pure Polyester Cover Cloth Weft Strength

探讨提高纯涤帐篷布纬向强力的方法。通过测试在剑杆织机、喷气织机、有梭织机上织制的同一织物品种的纬向强力差异,分析了在不同织机上织制同一品种时进纬侧和出纬侧纬线断裂强度及断裂伸长率,认为在织造帐篷布时进纬侧和出纬侧纬线断裂强度无差异,强力利用系数对纯涤帐篷布纬向强力影响较大,减小经纬织缩率可以提高强力利用系数,从而提高织物的纬向强力。

Methods of improving pure polyester cover cloth weft strength were discussed. Through testing weft strength difference of same fabric that were woven in rapier loom, air-jet loom and shuttle loom, the different breaking strengths and breaking elongations of weft inserting side and out side were analysed. It is considered that there is no difference between both weft inserting and out sides to weft breaking strength. Weft strength of pure polyester cover cloth was effected by strength utilization coefficient very large. Strength utilization coefficient could be improved by reducing warp and weft shrinkage so as to increase fabric weft strength.
