Development of shrink resistance cotton using fluorocarbon

다국어 초록 (Multilingual Abstract)

An attempt has been made to develop shrink resistance cotton textile by making it hydrophobic. The cotton fabric was made hydrophobic by treating with fluorocarbon resin emulsion at varying concentrations along with catalyst. The hydrophobicity was measured by carrying out water repellency test and also determining the water contact angle. The air permeability of cotton fabric was also determined and was not adversely affected. The untreated and treated cotton fabric was subjected to repeated domestic laundry condition and shrinkage was measured. In order to determine the impact of fluorocarbon treatment on fabric, the physical properties of treated and untreated cotton fabrics were compared. No adverse impact was observed in colour fastness properties. The tensile and tear strength showed good retention even at higher concentration of water repellent chemicals. This work finds wide use in home textiles and hotel industry. This work is of industrial interest as value added shrink resistance cotton textiles can fetch more export earnings.
