The Yarnmaster Prisma opens up a new world at ITMA 2019

Four sensor technologies interact intelligently and ensure unprecedented fault visibility and data quality. The unconventional new concept addresses all yarn quality problems related to material and the spinning process with an universal and multi-dimensional approach.

Four sensor technologies

Controlling the contamination in yarns is of greatest importance to the spinners. The YarnMaster PRISMA utilizes a sensor for foreign matter detection based on a brand-new RGB-color measuring technology. The new RGB F-sensor illuminates the yarn in the full spectrum of light, enabling the recognition of even the slightest difference in shade and glossiness in any type of yarn and color. The contamination of raw material with white polypropylene from bale packaging is very challeng-ing. To solve this difficult task, Loepfe developed the P4-Sensor, which utilizes the triboelectric effect. The sensor measures electric charge differences, which are caused during the winding process by different raw materials. This technology is able to detect contami-nation with white polypropylene very reliable. Beyond these, a world first dual measurement for basic clearing is presented to the visitors. On the YarnMaster PRISMA, the two dominant sensor technologies in yarn clearing are integrated into one single sensing head.

This uncon-ventional approach to use an optical and a mass sensor, functioning in perfect harmony, offers unprecedented possibilities and new levels of precision in yarn clearing. The fusion of four sensor technologies into one single sensing head –- YarnMaster PRISMA – guarantees previously unachieved performance and possibilities in quality control during the winding process.
