Beschreibung
Zusammenfassung:	Método de coloración de materiales con colorantes naturales que comprende las siguientes etapas: - preparar un baño de agua que comprende extractos de origen natural para la coloración y enzimas con actividad oxidasa o peroxidasa en los extractos indicados, a una temperatura de 30-60 °C y un pH de 4-6; - impregnar el material para la coloración en el baño anteriormente mencionado; en el que los materiales se someten previamente a un proceso de pretratamiento con plasma y/u ozono. The present invention describes a method to provide color to several materials/substrates, using compounds naturally present on nature - natural colorants, which implies contacting the material with a mixture of vegetable extracts and enzymes with oxidase, oxidoreductase or peroxidase activity in the extracts and also preferentially the pre-treatment of the material by plasma and/or ozone. The materials/substrates can be fabrics, fibers, yarns, films or structures of natural or synthetic origin, such as, but not limited to: fur, skin, leather, hair, silk, wool, angora, cashmere, cotton, linen, jute, hemp, sisal, cork, lyocell, polyamide, polyester, acetate or viscose and its mixtures. Therefore the present invention is useful for coloring natural and synthetic materials with natural colorants, presenting a color with a high fastness. The materials prepared under the present invention can be used to produce several articles, such as clothing, home textiles, shoes, upholstery and several coatings, among others.
