Dyeing of Cotton Fabric with Mahogony saw dust Using Milk as Mordant

Abstract

According to evidence, the usage of natural dye Mahogony(saw dust)on cotton fabric through a bio-based mordant, such as milk, has been incorporated in the study. Majorobjective of this research is to assess whether milk enhances uptake and fastness properties of dye on biocompatibility and antimicrobial potential of dyed samples. There are six samples of which three are mordanted with milk and three are unmordanted. Then, three pH levels were assigned for the dyeing-part: 4.5 or acidic, 7 or neutral, and 11 or alkaline-with the intention of viewing the influence of varying pH levels on dye absorption and fixation. It was noted in results that colour fastness from alkaline dyeing at pH 11 was better than acid and neutral dyeing in terms of wash and rub tests. Most of the mordanted samples had intense color and more stable than those that were not mordanted, thus showing effectiveness of milk as a co-mordant when natural dyeing. Allergy screening tests were performed on all samples with no reactions and skin irritations thus confirming that the procedure is dermatologically safe. Antimicrobial activity tests further proved that those fabrics are not just penciling out lipids but possess inhibitory effects on selected bacteria strains, thus implying even more hygienic value. Its study indicates that a transition from synthetic to natural dyeing is feasible in promoting Mahogony(saw dust)t and milk in sustainable textile dyeing as the environental friendly alternatives to synthetic colors and chemical mordants with promising functional properties required for skin contact textiles.
