摘要: The classical use of synthetic dyes is causing issues environmental pollution and heath risk. As a consequence natural are gaining interest, but the still includes toxic reagents such as metals mordants acids to enhance color yield. Therefore, we designed new chitosan-polypropylene imine dendrimer hybrid at 0–2000 mg/L treat wool before dyeing with cochineal. We compared dye exhaustion, depth, characteristics, fastness process dyed pristine metal mordanted wool. Results show that pretreatment improved exhaustion from 48 88 %, shifted saturation point toward lower concentration 3000 1000 mg/L, depth 13.68 for 15.17 23.89 process.
