The yarn suction gun (YSG) is used to draw the running yarn in the initial phase and when changing the bobbin in a continuous yarn production and is usually operated with compressed air. With a typical overall efficiency of compressed air generation, treatment and delivery, the electrical power requirement increases to over 75 kW just to operate a single YSG. Such high electrical power consumption must be addressed. One of the most effective ways to reduce the cost of compressed air generation and treatment is to replace the existing technology with one that is less energy intensive. Based on centrifugal blowers used in vacuum cleaners, a prototype was built and connected to various mixing chambers. Simulations and measurements were performed to evaluate the tension force acting on the yarn. Research on the use of vacuum for yarn suction is presented. It is estimated that after optimizing the suction by using vacuum, only 20 kW of electrical power will be required for one YSG, halving the cost of the current approach using compressed air generation.
