Effect of stitch patterns on moisture responsiveness of seamless knitted wool fabrics for activewear

Abstract

PurposeThe purpose of this research was to investigate the effect of knit fabric stitch patterns, as indicated by fabric thickness variations, on moisture responsiveness for different seamless knitted wool-based fabrics.Design/methodology/approachForty fabrics were created on a Santoni Top-2 circular knitting machine by using combinations of jersey, tuck and float stitches in combinations of wool/Nylon, wool, and spandex yarns. Physical properties of the knit fabrics as well as changes in fabric thickness during dry, wet, after 30 min air-drying and after 60 min air-drying conditions were compared. Repeated measures ANOVA tests and bivariate correlation analysis were conducted.FindingsThe results indicated that changes in moisture conditions had a significant effect on fabric thickness, and these changes differed by stitch pattern groups. Float patterns and tuck/rib patterns showed a continued relaxation of fabric thickness through all conditions, but tuck stitches and rib stitches showed a thickness recovery. Wool swatches, unlike the wool/Nylon swatches, increased their average thickness in after 60 min air-drying condition compared to 30 min air-drying condition.Originality/valueThis research documents the moisture responsive properties for wool based yarns, as emerging natural functional materials for seamless knitting industry, with applications in garments for activewear as well as healthcare.
