The shear properties of a fabric determine its performance properties as well as the appearances where it is subjected to a wide variety of complex deformations during usage as apparel. In This paper, woven fabrics have been made of cotton spun yarns with three different spinning techniques (ring spun, open-end spun and compact ring spun yarns) in weft direction. Some twill based weave structures were manufactured on the weaving machine with varying the weft density level. The Kawabata Evaluation System were used to measure the shear properties; shear rigidity, shear hysteresis at 0.5 deg. shear angle and shear hysteresis at 5 deg. shear angle. A statistical analysis was performed to get the effect of decided parameters on shear. A highly significant effect of the weave structures and weft density on the measured shear properties were found, while the type of weft yarns has insignificant effect. A multiple linear regression equations were derived to get a mathematical relationship between the influencing parameters; (the float length, yarn diameter, and weft density) and the shear properties. The derived regression equations had high correlation coefficients values.
