Enzyme pretreatment is a recent development in textile processing which has been found to improve the product qualities in respect of softness, luster, dye absorption and improve dimensional stability and comfort. Most of the research work on enzyme treatment is limited to fine Australian /New Zealand wool However the work on the effectiveness of enzyme pretreatment on Indian wool is not only scanty but not available. To study the effect of enzyme pretreatment on physio-chemical and mechanical properties of
carpet woolen yarn made from Indian wool in terms of dye ability, whiteness index and tensile strength a work is conducted based on Box-Benkhen experimental design A commercial proteolytic enzyme Swiss soft WLL is used for this experiment and a suitable economic recipe is formulated based on regression analysis of data of enzyme treated samples and compared with control samples. The results shown that
enzyme pretreated samples give better properties in respect of whiteness index and dye ability (K/S)than control sample, however the tensile strength of the enzyme treated sample shown decline effect with respect to control sample. It can be concluded that the enzyme pretreatment for carpet woolen yarn enhances the value of end products produced from the woolen yarn fetching more value for products and is more economical than the conventional preparatory process. .
