This article presents a study on the influence of bio-softening on the low-stress mechanical properties and hand characteristics of cotton fabrics. This paper a detailed account of the implication of the biosoftening operation of finished cotton fabrics. Enzymes are employed in various textile processes like pretreatment, dyeing and finishing by replacing harmful chemicals. Enzymes are protein molecules, which catalyse specific biochemical reaction. These are the naturally occurring high molecular weight proteins capable of catalysing chemical reactions of biological processes and hence known as biocatalysts. They are distinct from other non-biological origin proteins by their efficiency, specificity and sensitivity to control. A characterisitc feature of the enzyme is that it is not used by itself during the process and can be recovered at the end of the reaction. Enzyme treatment improves the hand value of cotton fabric in terms of softness, smoothness and stiffness. Bending rigidity and sheath stiffness values are lower for enzyme-treated fabric reflecting the improvement in softness and drapability. The lower tensile and compressional is lower indicating the improved softness and smoothness. The study indicates that the bio-finishing process improves the overall hand value of the fabric. |
