COMPARATIVE STUDY BETWEEN PIGMENT DYEING AND REACTIVE/DISPERSE DYEING ON POLYESTER/COTTON BLEND FABRIC (Pages : 40 - 48)

Polyester/cotton blended fabrics dyed with disperse/reactive dyes require a large amount of dyes, salt and chemicals which pollutes fresh watercourses. Due to the hydrolysis of the dye, the dyeing effluent consists of a large amount of hydrolyzed dye in a wash off process. The present study utilizes pigment which would not contribute to environmental pollution and undertaken to explore promising approach to reduce costs of dyeing process. In this work the polyester/cotton fabrics dyed with pigment was compared with disperse/reactive dyed polyester/cotton fabrics. For this a shade of three different concentrations; light, medium and deep were taken, dyed with disperse/reactive dye in conventional one bath two step processes and matched with pigment. The quality parameters like colour fastness to wash, rubbing, light and dry cleaning were assessed and compared with disperse/reactive dyed sample. The dyed sample showed good wash and light fastness properties within the range of colour change. In case of rubbing fastness light and medium shade showed good result but deep shade the result deteriorates and dry rubbing is better than wet rubbing. Pigment dyed sample showed unsatisfactory result of colour fastness to dry cleaning. The experimental data demonstrate that one bath pigment dyeing can be a suitable alternative dyeing process for polyester/cotton fabric against conventional dyeing.Download
