Diversity of spun yarn properties sized with and without prewetting

The goal of the paper was to investigate mechanical properties of yarns with various fineness and with similar twist factors made of Tencel fibers, sized with and without prewetting sizing process, using different size concentrations. It was found that the yarn sized with prewetting has always a lower size pick-up that the yarn sized without prewetting, as well as better relevant properties (greater abrasion resistance and lower frequency of protruding fibres). This is of paramount importance because of the advantages in ecological and economical terms, since the same or better properties are achieved with a lower size pick-up.
