Study on Dyeing Process of Bamboo Pulp Fiber Fabric with Pomegranate-peel Dye

Abstract

The pomegranate-peel dye was extracted by boiling in this paper. Through orthogonal experiments, using dye fixation rate as an indicator, it has studied the best dyeing process of pomegranate-peel dye for dyeing bamboo pulp fibers with direct dyeing and same-bath mordant dyeing methods. The dyeing process parameter are optimized through orthogonal experiments as follows: (1)with direct dyeing method, when dyeing 30minutes or 50minutes, the optimal process parameters are dyeing concentration X, dyeing temperature 80°C, and dyeing PH value 8; when dyeing 70minutes, the optimal process parameters are dyeing concentration 2/3X, dyeing temperature 80°C, and dyeing PH value 9.(2) with same-bath mordant dyeing method, when dyeing 30minutes, the optimal process parameters are dyeing concentration X, dyeing temperature 80°C, and dyeing PH value8; when dyeing 50minutes, the optimal process parameters are dyeing concentration 2/3X, dyeing temperature 60°C, and dyeing PH value7; when dyeing 70minutes, the optimal process parameters are dyeing concentration X, dyeing temperature 60°C, and dyeing PH value9. It is concluded that the bamboo pulp fiber dyed with pomegranate-peel dye has good dyeing performance, which meets the color fastness requirements of fabrics.
