Abstract
The aim of present study was to investigate dyeing and fastness properties of chitosan-cyanuric chloride hybrid (Ch-Cy) modified woolen yarn with madder natural dye which is used in hand-knotted carpet pile. Modified yarns were dyed with madder root natural dye and the impacts of some important factors such as Ch-Cy concentration, madder dye concentration, pH, temperature, and time of dyeing were investigated. Optimum dyeing results were obtained using 2%owf of Ch-Cy, 100%owf of madder dye, dyeing pH=7, temperature of 100 ˚C, and time of 60 min. Results revealed that Ch-Cy was effective in the improvement of dyeing properties of woolen yarns, so that the dye exhaustion and color strength values increased by 7% and 2 ratings, respectively. Fastness data against wash, light, and rub as well as colorimetric data indicated that wool modification did not impair color fastness of dyed substrates. Further, hue remained nearly unchanged compared to dyed pristine wool. Therefore, based on the results obtained, it was concluded that modification of woolen yarns with Ch-Cy resulted in better dyeing performance, deeper shades, and saving crude dye material in madder dyeing of wool.
