Abstract
The effect of enzyme treatments with consecutive softening by the use of silicone – polyurethane on low stress mechanical properties and hand values of jute/cotton union fabric have been studied on the Kawabata evaluation system (KES). The results indicate that the enzyme treated, silicone – polyurethane finished fabric has significant (p<0.05) improvement in tensile resilience, fabric extensibility, compressional resistance and friction co efficient, whereas fabric thickness, linearity of tensile, surface roughness, bending and shear rigidity and their hysteresis are reduced compared to the untreated fabric. Under the Kawabata system, the Koshi (stiffness) value of the finished fabric is decreased by 1-9%. Numeri (smoothness) and Fukurami (fullness and softness) values are increased by 11-20% and 3-4% respectively compared to the untreated fabric. The variation in primary hand values are significant (p<0.05). The total hand value (THV) is also increased by 6% and 44% for the case of 40/60 and 50/50 jute/cotton union fabrics, respectively. This study confirms the possible usage of jute/cotton fabric in the apparel segment.
