Investigation on Changes of Physical Properties of Various Types of Denim Fabric by Different Types of Wash

Abstract

Garments washing are very useful for modifying garments, especially which is made of denim fabric. By doing wash we can change the appearance, outlook, and comfortability. Enzyme washing of denim garments helps in bio- polishing and to fade the color of the denim to the desired degree depending on the processing time and conditions. On the other-hand bleach wash and acid wash also very much effective on denim fabric. Bleaching is done by a strong oxidization agent and makes the garments blue light shade and acid wash is done for irregular fading in garments. This paper presents the impact of acid, enzyme, and bleach wash on various types of cotton denim. The physical and mechanical properties of the tested denim were analyzed using standard test methods. The properties that were analyzed include tear strength, tensile strength, and shrinkage percentage, and fabric weight variation before and after wash. And also found that maximum denim fabric after wash tensile and tear strength increases on the contrary after washing fabric shrinks. The weight of the fabric after wash increased slightly.
