喷气涡流纺缝纫线的开发与性能测试

Development and Performance Test of MVS Sewing Thread

采用喷气涡流纱作为原料,开发了一种新型缝纫线,并对其性能进行测试与分析。测试结果表明,喷气涡流纺缝纫线单线强力好,符合国家标准GB/T 6836-2007优等品要求;喷气涡流纺缝纫线纱疵少,降低了缝纫过程中的断针率和纱线断头率;喷气涡流纺缝纫线毛羽指数低,减小了毛羽对缝纫产生的危害;喷气涡流纺缝纫线断裂伸长率较大,降低了缝纫线的断头率。实验结果显示,喷气涡流纺缝纫线符合缝纫线的内在质量要求,属于质量较优的缝纫线品种。

A new type of sewing thread was made with MVS single yarn as raw material and its related performance was tested and analyzed. The test results showed the following performance characteristics： the MVS sewing thread had a good strength to meet the top quality requirements of national standard GB/T 6836-2007; it had fewer yarn defects,reducing the broken needle rate and yarn breakage rate during the sewing process; its hairiness index was so low that it could reduce the hairiness hazards during the sewing process; it had a high elongation at break,which reduced the sewing thread＇s breakage rate. According to the experimental results,the sewing thread met the internal quality requirements of the sewing thread and was classified to a better quality sewing thread group.
