Dyeing, Printing and Creating Prototypes of Textile Products Using Colourant from Mangosteen Leaves

Abstract

The objectives of this research were: (1) to study the dyeing of cotton with natural dye extracted from mangosteen leaves, (2) to produce powdered natural dye from mangosteen leaves and apply it for printing and painting on cotton fabric, (3) to explore discharge printing on cotton dyed with mangosteen leaf dye, and (4) to create prototype products using dyed and printed fabrics made from mangosteen
leaf dye. According to the experimental results, cotton dyed with mangosteen leaf extract appears brownish-red. When alum is used as a mordant, the resulting fabric becomes brighter, while fabrics treated with ferrous sulfate during printing acquire a brownish-black hue. Powdered natural dye from mangosteen leaves can be used for printing or painting on textiles, yielding the same shade as that of cotton dyed with mangosteen leaves. Dyed cotton can be decolorized using potassium permanganate, creating patterns with white veins reminiscent of batik designs. The colour fastness of cotton dyed with mangosteen leaf dye is moderate for washing, light exposure, and rubbing. However, it exhibits good to very good colour fastness to perspiration and water. Dyed and printed fabrics can be processed into various prototype textile products, such as shirts, shoes, and bags, offering a unique identity for the enterprise group.
