Comparative Enactment of Fluorocarbon-free and Fluorocarbon-based Water Repellent Finishes on Cotton Single Jersey Fabrics

Abstract

In this study, single jersey derivatives of knit fabric were taken to evaluate the performance of water repellent finishes on knit fabrics properties. Here, polo pique and single jersey knit structured fabrics were treated with different types of water repellent chemicals at different formulations. The levels of water repellency of the fabrics were measured in accordance with ISO 4920:2012spray rating test method. To assess the performance of water repellent finishes on knit fabric properties, GSM, bursting strength test according to ASTM (D 3786-87) method, color fastness to wash according to ISO- 105/ C06-C2S method, color fastness to water with ISO 105-E01 method and color fastness to rubbing with ISO-105-X 12 method were done. The results showed that the water repellent finish type and concentration were very important parameters to obtain water repellent fabrics with desirable properties.
