In the sewing of water repellent fabrics, it is necessary to give waterproof property to the seam. It is also necessary for the seam to maintain its waterproof level during wearing in end use.In this study, the factors which had effect on the waterproof property of the seam were discussed and a seam fatigue tester was introduced to simulate the action during wearing in end use.In general, the waterproof level of the seam became lower by the cyclic loading action of the fatigue tester because of the damage of stitched part in the seam.The factors which had effect on the waterproof property of the seam were sewing thread, stitch length, sewing needle and etc. It was shown that water repellent finish for thread was essential.From the point for obtaining durable waterproof property of the seam, some technical methods were proposed here. It was suggested that a method using a composite yarn (conventional filament yarn and textured bulky yarn) was the most useful. On the other hand, a method using polyurethane resin as sealer was excellent in experimental data but further investigation would be necessary.

在防水布料的缝制中，需要对接缝赋予防水性。在最终使用过程中，接缝也需要保持其防水等级。本研究讨论了影响接缝防水性能的因素，并引入接缝疲劳测试仪来模拟穿着过程中的作用。一般情况下，由于接缝处缝合部分的损坏，在疲劳试验机的循环加载作用下，接缝的防水等级会降低。影响接缝防水性能的因素有缝纫线、针迹长度、缝纫针和实践证明，线的防水处理是必不可少的。从获得接缝持久防水性能的角度出发，提出了一些技术方法。据认为，使用复合纱线（传统长丝纱线和变形膨体纱线）的方法是最有用的。另一方面，使用聚氨酯树脂作为密封剂的方法在实验数据方面非常出色，但需要进一步研究。
