Simultaneously Dyeing and Durable Press Finishing of Cotton Fabric

Abstract

Cotton is the most widely used cellulosic material in the textile industry, especially for apparel purposes but, has a tendency to wrinkle badly, degrading its aesthetic value and have poor smoothed drying properties. Dyeing and crease resistance finishing process are applied to improve the wrinkle resistance and its aesthetic value respectively. Conventionally, dyeing and durable finishing of cotton is conducted separately by dyeing cotton first, and then finished with a cross-linking agent. However, these traditional processes are time and chemical consume processes. Many researchers have attempted to combine dyeing and easy-care finishing process in to one step. The challenge was difficult to produce fabrics that have deep shades, good Colour fastness and excellent crease recovery performance simultaneously. Hence, the aim of this work was to conduct combined dyeing and easy-care finishing of cotton fabrics with reactive dyes, citric acid and fibroin solution using pad–dry–cure methods. In this work, fibroin is used as an additive to enhance the degree of cross-linking and as a cat ionizing agent to improve the exhaustion of the dye. The parameters were investigated and optimize with respect to colour strength, colour fastness and mechanical properties of the treated fabric. The efficiency of combined dyed and finished fabrics with reactive dye, citric acid and fibroin has been studied. Better colour strength, crease recovery angle, breaking strength, and fastness properties were obtained as compared with conventional process. When the concentration of fibroin increased the K/S values, colour fastness properties, and crease resistance properties were improved.
