An investigation into the parameters influencing the abrasion and friction properties of composite yarns containing metal wire

Abstract

This paper is focused on the selected parameters that influence the abrasion and friction properties of composite yarns containing metal wire. In the experimental study, the composite yarns containing metal wire were produced on a hollow spindle twisting machine according to the method of covering. The composite yarns containing metal wire were produced with seven different cover yarns varying in their raw materials and structures. These were: polypropylene, cotton, polyester/cotton core-spun, continuous filament polyester, continuous filament nylon 6.6, polyester/polyester core-spun, and polyester cut fiber yarns. These yarns were cross covered over stainless steel (SS) wires having two different diameters of 50 pm and 100 pm. The performance tests selected for these yarns were abrasion and friction as because these types of yarns are vulnerable to rubbing. Abrasion tests of composite yarns containing metal wire were performed with a modified crockmeter test instrument while the friction tests were carried out by using a yarn friction coefficient measurement device. According to the results of the statistical analyses performed using the experimental values obtained from the tests, abrasion resistance and friction properties of the composite yarns were affected by the yarn parameters like cover yarn type and wire diameter.
