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

Reducing steaming times in the printing of nylon/elastane blend fabrics via chemical modification
Atav, Rıza; Yüksel, M.F.; Yakin, İ. (Lukasiewicz Research Network - Institute of Biopolymers and Chemical Fibres, 2021)Nylon fibres are commonly used in blends with elastane. One of the problems encountered in the printing of nylon/elastane blend fabrics is the necessity of long steaming times for fixation, which causes an increase in ... -
THE INVESTIGATION OF THE EFFECT OF CHEMICAL MODIFICATION WITH CHITOSAN TO PROVIDE SINGLE BATH DYEABILITY OF NYLON / COTTON BLEND FABRICS
Atav, Rıza; Soysal, Selma; Çağlar, Erkan; Yıldız, Fatma (Chamber of Textile Engineers, 2022)In this study, it was aimed to make each fiber components dyeable with a single dyestuff so that nylon / cotton blend fabrics can be dyed in the same bath. For this purpose, it was aimed to make each of these fibers dyeable ...
