Optimising vortex cooling time for industrial lockstitch sewing machines

Popis výsledku v původním jazyce

Forced air or vortex cooling is the most common method for cooling sewing needles in heavy industrial sewing machines, for example, in the automobile industry. The vortex tube separates compressed air into hot and cold streams, with the cold stream beingcontinuously pointed at the sewing needle, decreasing the needle temperature. In this research, the impact of air cooling is determined for sewing without cooling, sewing with continuous cooling and sewing with optimised cooling times. For the optimisedcooling time, the cooling is performed only at the time of stoppage during the sewing process. The results show that the impact of continuous cooling and cooling before sewing stoppage are similar, thus it is unnecessary to maintain continuous cooling.The sewing process is performed using two polyester core-spun threads with classic denim fabric, and the tensile properties of the threads are compared at different speeds of sewing (from 1000 to 4700 r/min) at continuous cooling, the opt
