METHOD FOR DYEING SILK FABRIC BY ALGAE

摘要

A method for dyeing a silk fabric by an alga is provided to prevent the eutrophication of the water quality due to the increase of the inorganic nutritive salts. A proper amount of an alga is prepared according to the weight of the target salt, washed, crushed and filtered so that the extraction solution is manufactured. A silk fabric via a pre-process such as the scouring is impregnated into the extraction solution, agitated at the atmosphere of pH 3.0-8.8 and 20-80 degrees in centigrade for 25 to 40 minutes, pressed slightly, so that a dyeing process is performed. Since the alga as the natural dyes is used, the dyeing method dose not harm to human beings.
