Chlorophyll is an abundant pigment found in all green plants, algae, and cyanobacteria. This study usesmethanol, acetone and water to extract spinach and mate powders in order to examine the possibility ofdyeing animal fibers with chlorophyll without chemical alteration. It was shown that methanol extracts ofspinach and mate powders can be effectively used to dye wool and silk fabrics if the extract is mixed withwater by methanol:water 65:35 v/v. Compared to methanol extract, the acetone extract showed lower chloro-phyll yield and lower dye uptake. Water was not an appropriate solvent for chlorophyll extraction and dye-ing. Spinach powder showed a higher dye uptake than mate powder due to the higher chlorophyll contentthan mate powder. It is possible that the chlorophyll dyeing of wool and silk fabrics is due to the hydrogenbonding between the hydroxy amino acids in fiber and the carbonyl groups of chlorophyll. These carbo-nyl groups are on the heterocyclic ring and the methyl and ethyl side chains of chlorophyll.Key words: Chlorophyll, Spinach, Mate, Methanol, Acetone; , , , ,
