The research aims to evaluate the effectiveness of catechin-based natural colorants for dyeing cotton and enhance colorfastness.
Utilized a binary mixture of cocoa and cutch extracts as natural colorants for dyeing.
Applied central composite design under response surface methodology to select dyeing variables.
Conducted experiments with various mordanting techniques, including pre, post, and meta mordanting.
Employed microwave treatment for improved dyeing efficiency.
Achieved a color yield of K/S = 2.48 under optimized dyeing conditions.
Tannic acid pre-treatment resulted in a color strength of K/S = 4.11.
Post-dyeing with myrobalan extraction yielded a color strength of K/S = 2.85 with good colorfastness.
