Abstract:

This paper describes a new and simple method of decreasing the strip-back phenomenon of core-spun yarns. In the method proposed, before the production of these yarns, the core part was coated with a Methyl Methacrylate (MMA) binder using a purpose-built method based on the conventional pad-dry-cure (PDC) system. Two counts of polyester filament yarn, namely 111 and 44 dtex, were used as the core part, and the nip pressure of the padding system was changed on two levels to evaluate the effect of the pick-up percentage. The core-spun yarns were produced on a modified ring spinning frame. The tensile properties of the core-spun yarns, their cover factor after abrasion, and the abrasion resistance and pilling of the fabrics woven were studied. The results obtained showed the effectiveness of the method proposed for the improvement of the strip resistance of core-spun yarns after the abrasion process, as well as of the abrasion resistance and pilling of woven fabrics. The statistical evaluation, based on one-way analysis of variance, revealed a significant difference between the properties of conventional and modified core-spun yarns in most cases.
