To optimise yarn clearing further, Loepfe, a leading manufacturer of sensors and monitoring equipment for yarn spinning and fabric weaving processes, has developed the new adjustment tool P-Matrix for its YarnMaster Zenit+, which increases the clearing efficiency substantially. Extensive tests in a spinning mill in India showed impressive results.

The YarnMaster Zenit+ combines different sensor principles in one single device. This enables the customer to effectively control yarn quality. The P-sensor used for the synthetic foreign matter detection is based on the triboelectric effect. The sensor is sensitive to different materials, and is therefore, able to distinguish between cotton and synthetic foreign matter, such as polypropylene, polyethylene, polyamide (nylon) etc.

The unique sensor principle in combination with the new P-Matrix improves the synthetic foreign fiber clearing substantially. The P-Matrix facilitates the perfect adjustment of the clearing. The result is not only an effective clearing of synthetic contaminations, but at the same time an optimised overall production efficiency with less waste.”
