Abstract

The study was focused on investigating the impact of different washing processes (dark shade, medium shade, light shade) on various properties of denim fabric. Two different types of fabrics with twill and dobby weave constructions were produced from cotton, spandex, and polyester yarn, and different types of washing processes were applied. Dimensional stability, tensile strength, tearing strength, EPI and PPI, weight, colorfastness to rubbing, colorfastness to perspiration (acid and alkaline), and colorfastness to water was investigated and comparisons were made statistically between the before washed sample and after washed sample. It is found that the process result shows better tear and tensile strength in case of dark & medium shade wash than light shade wash. On the other hand, weight and EPI & PPI have shown better result for light wash than other wash. Colorfastness to rubbing, Colorfastness to water, and Colorfastness to perspiration (acid and alkaline medium) are similar. The shrinkage% is higher especially in the weft direction of the fabric for light wash than the dark wash.

Highlights

Denim is one of the predominant clothing products in the textile field recently [1]
This paper aims to determine the impact of different shade wash on various properties of twill and dobby weave denim fabric
Fabric weight, tear strength, tensile strength, EPI and PPI, various colorfastness properties, and dimensional stability were analyzed by applying different wash shade on denim fabric

Summary

Introduction

Denim is one of the predominant clothing products in the textile field recently [1]. It is a very strong, and stiff fabric constructed with weft white yarn and warp colored yarn which are fashion trend for all classes people, all seasons, all climatic conditions and all over the world [2], [3]. Insoluble matters or other impurities from the fabric are removed and it is performed to produce effects such as color fading with or without patchiness, crinkles, puckering, hairiness softened hand feels, and stabilize dimensions in denim garment [7], [8]. Due to after wash shrinkage of some garments, it could be purchased directly from the store or shop as per required size [9].
