In this study an attempt was made to investigate bio pretreatment and chemical pretreatment process and observe the effects in terms of absorbency, bursting strength, wash and rubbing fastness, water, and energy consumption. Four samples (S1, S2, S3 and S4) were prepared by different pretreatment processes and then were dyed with two different reactive dyes. When compared to chemically prepared fabrics, biopretreated fabrics demonstrated improved abrasion resistance, bursting strength, and wash fastness. A significant improvement in sustainability aspects had observed in terms of lower demand for energy and water. This study focused to introduce an optimizable eco-friendly pretreatment process with enzyme application of the cotton knit fabrics.
