无针缝服装接缝性能研究分析

以3种无针缝服装防水透气面料为研究对象，在一定时间、温度、压力条件下通过热压或超声波熔接，与同面料的针缝接口部位进行断裂强力、耐水压和水洗脱胶的比较。结果显示：3种面料不管用进口还是国产热熔胶膜，也不论是热压或超声波熔接，其接口部位强力均超出常规形式针缝的强力。因此无针缝加工不仅能做到防水透气，赋予接缝良好的弹性，同时能很好地保证户外运动服装对接缝强力的要求，水洗牢度也完全符合要求。

Seam Performance Analysis of No-Stitched Seam Apparels

Three typical types of water proof and breathable fabrics are selected for the study. Fabrics are seamed by press bonding or ultrasonic waves at certain conditions of time, temperature and pressure. Performances such as fracture strength, water pressure resistance and debonding are compared to stitched seams on same fabrics. Test results indicate that no-stitched seams on all three fabrics have higher fracture strength than regular stitched seams, whether imported or domestic hot melt adhesives are used, or press bonding or ultrasonic waves are adopted. No-stitched seams are not only water proof and breathable but also flexible, and can guarantee the required seam strength and washing fastness.
