DEVELOPMENT OF NEW PRODUCTS AND COLORING THE PRODUCT BY USING ENZYMES IN THE PRETREATMENT PROCESS OF COTTON FABRICS

In this study, an environmentally friendly process was developed with amylase, cellulase and pectinase enzymes without using bleaching chemicals in the pretreatment process of 100% cotton woven pile fabrics. After enzymatic pretreatment, a product ready for sale was obtained without dyeing. The obtained product has been dermatologically tested by approved organizations and it has been concluded that it is anti-allergen and anti-carcinogenic. Fabrics pretreated by conventional method and fabrics pretreated by enzymatic method were dyed with reactive dyestuffs. After dyeing, ΔE color differences, hydrophilicity and fastness tests were applied to examine the differences between fabrics dyed by both methods. It was concluded that the dyestuff gain between 6-37% and cost savings between 6-27% in the midtone and dark colors of the fabrics. © 2022. Tekstil ve Muhendis. All Rights Reserved.
