Pilling properties of wool single jersey made of compact and conventional ring yarns after anti-felting treatment

Abstract

This work studied the differences between wool single jersey made from compact and conventional ring-spun yarns composed of surface-modified fibers with different anti-felting treatments. Wool yarns (100%), produced from the fibers modified by two commercial chemical treatments, Basolan®88 and Kroy-resin, were spun according to compact and conventional ring-spinning systems in two different twist factors of spun yarn. The surface morphology and physical properties of wool fibers and conventional and compact ring yarns and the pilling properties of these fabrics were examined and compared with each other before and after the chemical treatment. The breaking strength of modified fibers decreased if compared with the control. Results indicated that the surface morphology of wool fiber changed by Basolan®88 and Kroy-resin treatment, and a lower friction coefficient increased with the differential frictional effect value. The hairiness index ( S3) of compact yarn was a reduction by 60% and the strength and elongation percentages were higher compared with conventional ring yarn. The fiber packing density of compact yarn was 30% higher from the fiber distribution pattern in the yarn cross-section. Another important finding was that the fabric produced with compact yarn showed better anti-pilling property and more mass loss.
