Effect of Tuck and Miss Stitch on the Geometrical Properties of Regenerated Cellulose Plain and Derivative Knit Structures

This study aimed to analyze the effect of tuck and miss stitch structures of regenerated cel- lulose fabrics like viscose, modal, Tencel, and bamboo. The fabrics were developed with the same stitch length and tightness factor and analyzed for their geometrical properties after dry and wet relaxation. The study results revealed that wet relaxation treatment showed more significant changes in the geometrical constant values (K) than the dry relaxation process. The highest wale density change was noted with cross miss stitch fabric and a maximum course density change noted for cross tuck samples after dry and wet relaxation. The differences in wale and course density were noted as statistically insignificant for the aforementioned struc- ture after dry and wet relaxation (p > 0.05). However, in the case of stitch density, there is a statistical significance noted for the tested samples (p < 0.05). The maximum changes were noted in plain fabric followed by twill structure. The loop shape factor (Kr) value suggests higher distortion in the cross tuck fabric and after wet relaxation over dry relaxed samples followed by plain, twill, and miss stitch structures, and we also noted the relaxation process did not alter the loop shape factor (Kr) significantly between the dry and wet process (p > 0.05).
