Resumo
This study presents partial results of a research that explores the possibilities of coloring bamboo slats using ecologically friendly techniques. Bambusa vulgaris slats were used to perform natural dyeing processes using Curcuma longa as a natural dye. Different shades are obtained as a result of the dyeing process through the use of 3 types of mordants (potassium aluminum sulfate, iron acetate, and lye solution rich in caustic soda). Empirical evidence demonstrates natural dyeing processes of bamboo that can initially be considered as sustainable alternatives that use simple, very low-polluting and environmentally friendly techniques.
