Description
Summary:Yarn breakage or ends-down in ring spinning adversely affects spinning efficiency. An ends-down event may continue for an extended period of time before it is detected and attended to. This study explored a novel approach to detect yarn breakage or ends-down in ring spinning, through changes in ring temperature after an ends-down. Numerical simulation and experimental verification were used to examine the ring temperature changes during the yarn breakage process. The results showed that higher ambient temperature, spindle speed and yarn count (tex) resulted in a higher ring temperature and a longer ring cooling time. But the rate of ring temperature decrease immediately after yarn breakage was quite high, dropping 50% between equilibrium and ambient temperatures in approximately 16 s for most spinning conditions. The model and results of this study offer the basis for a new yarn breakage detection option in ring spinning based on the temperature change of the ring.
