摘要

Enzyme softening of cotton hosiery ring carded, ring combed and rotor yarns (19.68 tex) has been carried out using commercially available Bio-soft L+ acid type cellulase enzyme at optimized conditions. Knittability of enzyme-softened yarns has been studied and compared with their respective waxed yarns by measuring the actual loop length of knitted fabrics produced under different input tension and by maximum tight structure possible to knit in the given machine. It is observed that the enzyme softening improves the knittability of all three types of yarns to a significant level; the knittability of ring carded yarn improves to the level of ring combed yarn. Enzyme-softened rotor yarn shows the better knittability than enzyme-softened ring carded and combed yarns. The enzyme softening of yarn also increases the dimensional stability of single jersey fabric to a remarkable level. Among the enzyme-softened ring carded, ring combed and rotor yarns, the dimensional stability of ring combed yarn fabric is found to be very good. Changes in mass per unit area and thickness remain almost unaltered after wet relaxation treatments in case of enzyme-softened yarn fabrics.
