Extraction and Application of Natural Dyes from Brazilwood and Water guava leaves

Abstract

The use of natural dyes for batik has some advantages because it produces a unique exotic color with exclusive imaging and is environmentally friendly due to the waste easily degraded. The purpose of this research was to obtain textile dye extract from brazilwood (Caesalpiniasappan L) and water guava (Syzygiumaqueum)leaves with various compotitions and fixer, i.e., alum, calcium carbonate and ferrous sulphate. The mordant used is alum and soda ash (Na2CO3). The highest color intensity (87.63%)was obtained from brazilwood/water guava leavesratio 50/50 and ferrous sulphate fixer, while the lowest (35.60%) from ratio 25/75 and calcium carbonate fixer.

Development of Eco-friendly Dyeing Process Based on Caesalpinia sappan L. Bark, Cocos nucifera Fiber and Leucaena leucocephala Leaves

“…Water-soluble braziline flavonoids are the main source of red dye on Caesalpinia Sappan Linn. or Sappanwood (family Leguminosae) [34]- [36]. The extract has been used extensively as a natural dye, especially in the textile industry due to its low toxicity and low cost [37]- [39].…”
