Investigation of static electricity amount of wool and wool blend fibers depending on machine speed and fiber blend

Abstract

Fibre-fibre and fibre-metal frictions lead to static electricity on 100% wool and wool blended fibres during the yarn production due to the triboelectric charging. In this study, the variation of the static electricity deposited on the fibre while moving on the fibre drawing machine, depending on the machine speed and the blend mixture, was examined. Static electricity of 100% wool, 45/55% wool/polyester, 90/10% wool/nylon blended fibres which were finish oiled during the process, was measured on drawing frame. Measurements were made for 3 different speeds of the frame. Static electricity was calculated by surface charge density measurement method. It was determined that fibres which cause an increase in the ratio of waste due to the wrapping problem to the cylinders of drawing machines, have higher amount of static electricity in the yarn production.
