摘　　要：竹节纱由于其特殊的结构使得它的纱线强力较同等特数普通纱低,在纺纱过程中纱线容易断头,影响生产效率。为了提高竹节纱的强力,减少断头,研究了竹节纱的固定弱节分布规律,并通过定位包绕固定弱节的方法,大幅度提高了竹节纱的整体强力,进而研发出高支竹节纱,使得竹节纱在强力满足生产工艺的情况下,可以整体纺制得更细[1]。Slubby yarn had lower yarn strength than ordinary yarn due to its special structure. The yarn broke easily during spinning process. Production efficiency would be affected. In order to improve the strength of slubby yarn and reduce the breakage, thedistribution law of fixed weak links of slubby yarn was studied. The overall strength of slubby yarn was greatly improved by positioning and wrapping the fixed weak links. High count slubby yarn was developed, which made slubby yarn＇s overall spinning finer whenits strength met production process.
