Dyeing effect optimisation analysis of cotton composite material

Cotton composite material, also called cotton cloth, is the fabric weaved with cotton yarn as raw material. Cotton fabric becomes one of the most common fabric for its excellent wearability and is widely used in garment fabric, decorative fabric and technical fabric. This paper conducts factor test in the aspects of dyeing rate and colour fastness of cotton composite material through experimental analysis and verification. Through the comprehensive analysis of various factors, influence on the dye-uptake rate varies from that on the colour fastness, therefore, in order to get a better dyeing effect, the values of the dye-uptake rate and the colour fastness need to be adjusted properly for finding out the optimal dyeing effect.
