    Abstract

    During the Siro-spin process, breakage of one strand arm would cause an extremely serious fabric fault. It is difficult to detect the breakage of one strand arm and give indication for operators. In this research, a kind of photoelectric detection sensor was developed. The sensor distinguishes breakage of one strand arm by probing the difference of the pulse width of the pulse before and after breaking one strand of the yarn in the process of Sirospun. The experimental results show that the system can detect the breakage of one strand arm. The average pulse width is about 0.78 μs in normal status and 1.95 μs in errors status for 40-s yarn. That was caused by the change of yarn diameter, balloon shape, and hairiness. The pulse width was also affected by the yarn thickness and position of the steel plate.
