Abstract

This paper shows that fabric and seam strength loss (%) of the selected denim trousers occurred for different washing applications. At first, a commonly used denim fabric of 12.5 Oz/yd2 was selected to make the trousers containing two types of seam i.e. superimposed and lapped seam. Then bleach, enzyme and acid wash were applied on the produced trousers and fabric & seam strength loss were determined by using related standard and equipment. It was found that fabric strength loss is higher in case of acid wash and the loss of seam strength is higher in case of enzyme wash.

Summary

Introduction

Over the past three decades Bangladesh’s RMG (readymade garments) industry has expanded rapidly [1]. A range of treatment methods such as bleaching treatment, enzymatic treatment, acid treatment, and silicone treatment are widely used for the washing of denim garments They all aim for new possible effects of the appearance of fabric [7]. Enzymes are primarily used to achieve a smoother, less sticky fabric sheet, to reduce the tendency to form a pill, to improve the handling and to smooth the surface, together with conventional softeners. Development studies in this area focused on the application of enzymes to cellulose materials based on cotton, linen, viscose and their blending with synthetic fibres [13]-[18]. This paper investigated the impact of bleach, enzyme and acid wash on the physical and mechanical properties of denim apparel
