Effect of Burn out Print on Physical and Mechanical Properties of Knit Fabrics

Abstract

This paper is an experimental investigation of the effect of Burn out print on physical and mechanical properties of knit fabrics. In this work two different colored fabrics with same fabric structure and composition were printed by Burn out printing method to investigate and determine the effect of Burn out printing on their physical and mechanical properties such as GSM, CPI & WPI, stitch length, water absorbency, dimensional properties, color fastness, pilling resistance, abrasion resistance, bursting strength and tensile properties. In this study, Sangria and Thai Curry colored of 50% Polyester and 50% Cotton blended Single Jersey knitted outerwear fabrics were taken. After Burn out printing both fabrics were tested and investigated to determine and compare their properties. Typical printing and testing methods were followed and then physical and mechanical properties were analyzed under standard condition. It is observed that fabrics weight (GSM) is decreased from 170 to 140 after Burn out print. Fabrics CPI, WPI, stitch length and water absorbency property are also decreased after Burn out print. Burn out print has also impact on fabrics dimensional property
