Influence of Yarn Properties on the Low-Stress Mechanical Behavior and the Hand Quality of Single Jersey Knit Fabrics

P. Radhakrishnaiah


Yarns showing variation in compression, bending, tensile and surface properties were converted into single jersey knit fabrics. The low-stress mechanical behavior of the yarns and their corresponding fabrics was evaluated using Kawabata equipment. The fabrics were also evaluated for their subjective hand quality. Regression analysis was carried out to understand the relationships between yarn and fabric properties and also between the measured fabric properties and the subjective hand values.

Results showed that only a few yarn properties exert significant influence on the corresponding fabric properties. Compressive softness of the yarn showed a very high positive correlation with the softness of the fabric. Fabric softness, in turn, predicted hand quality to a very high degree of accuracy. Other fabric properties such as shear rigidity, surface roughness, variation of surface friction, linearity of the compression curve, shear hysteresis and bending hysteresis also showed a high degree of association with hand quality. A group of nine fabric properties predicted hand quality with near 100% certainty.
