Abstract

OCR 09WP 26 / 03 / 2569 The natural green pigment derived from the Terminalia chebula tree and soil serves as an absorbent for dyeing fibers. Hydrated potassium aluminum sulfate (potassium alum) is a natural food coloring raw material. The components include Terminalia chebula tree extract, indigo dye, fermented indigo paste, and clay powder. The natural green pigment from the Terminalia chebula tree is a developed component of the mixture. Natural dyes can be used to color fibers for weaving fabrics, reducing the use of chemical dyes, minimizing pollution, and creating added value. It is used to support community products, as the natural dye powder can be dissolved in warm water to dye fibers.
