Dyeing of bambo fibers can be done by natural and chemical dyeing methods. . In the natural method, natural materials with pigments, such as tea, pomegranate skin, onion skin, apple skin, walnut skin, and saffron are used to dye bambo fibers, but in the chemical method, chemical materials and dyes are used to dye bambo fibers Chemical dyes for dyeing bambo fibers include acid dyes, alkaline dyes, vat dyes, sulfur dyes, chromic dyes, disperse dyes, azoic dyes, and optical clarifying dyes [1].
In a research about the dyeing of bambo fibers using pomegranate skin, parameters such as the percentage of addative substances such as sodium chloride, sodium carbonate, color fixation temperature on bambo fibers and time were investigated. The result of this research was that the optimal condition for dyeing bambo fibers occurs when the percentage of sodium chloride is equal to 40 grams per liter and the concentration of sodium carbonate is 4%. Also , the optimal color stabilization temperature and time was introduced as 50 degrees Celsius and 45 minutes [2,3].[2،3].
