Analysis of drape co-efficient, bending length, flexural rigidity and tightness factor of 4×1 rib, 4×4 rib, half cardigan and full cardigan knit structure fabric

Abstract

This study investigates the result of various knit structure on various properties of rib fabric. The acrylic yarns were accustomed to make 4×1 rib, 4×4 rib, half cardigan and full cardigan structured fabrics using manual V-bed knitting machine during this analysis work. The consequences of knit structure were measured regarding drape coefficient percentage, bending length, flexural rigidity and tightness factor. The results disclosed that the fabric properties are greatly influenced by knit structures. 4×4 rib knit structured fabric showed the highest value for all tested properties except drape coefficient and half cardigan knit structured fabric showed the lowest value. 4×1 rib knit fabric possessed the highest drape coefficient percentage. The bending length and flexural rigidity was investigated in both wale and course direction. Simultaneously, surface and back sides bending length were also calculated. From the above mentioned data it's been known that the effect of knit structure on flexural rigidity in both wale and course direction were influenced in a very same chronological way. The highest tightness factor was observed for 4×4 rib structured fabric.
