摘　　要：分析并条波谱图12 cm～14 cm处机械波产生的原因。利用电容式条干均匀度仪检测纱条条干不匀,通过延长其测试时间,使检测波长达到或超过25个,以保证波谱图的可信度;同时根据不匀曲线图计算对应在并条波谱图上的机械波波长值,经分析及试验验证后认为:并条机一罗拉或传动一罗拉的齿轮或轴承出现了问题,都会造成并条12 cm～14 cm的机械波。Causes of drawing sliver 12 cm - 14 cm mechanical wave were analyzed. Capacitive yarn evenness tester was used to test yarn evenness,through extending test time 25 or more testing wave lengths can be got to ensure spectrogram credibility. At the same time, wave length of mechanical wave in drawing sliver spectrogram can be calculated according to unevenness curve. After analyses and test verification,it is considered that drawing sliver 12 cm - 14 cm me- chanical wave will be caused by drawing frame roller or drive roller or bearing oroblem.
