A Comparison Among Performance Characteristics of Various Denim Fading Processes

Abstract
The aim of this study was to examine the effect of fading methods such as sand-blasting, laser and washing on performance properties of denim products. In this study, on one type of denim fabric, fading methods by laser and sand-blasting were applied in different intensities and pressures, and then fabrics were washed with the aid of different types of washing processes. Also, another denim fabric group was only washed by applying different types of washing processes. At the end of the study, loss of weight, color abrasion and loss of tensile strength of denim fabrics were measured. As a result, fading methods decreased tensile strength and weight values and the decrease rates changed in line with the intensity and the pressure of fading methods. Furthermore, color abrasion values of the fabrics changed due to the intensity and the pressure of fading methods. Back-staining values decreased after laccase enzyme and hypochlorite bleaching, but after other washings, back-staining values increased due to washing type.
