Técnicas e saberes tradicionais na produção de cores

Abstract

This paper deals with the production of dyes from various parts of vegetables. There is a brief report on the use of natural dyes from ancient times; presentation of plants that can be used for dye extraction, the process of preparing these plants, the colors provided by each one; specification of mordant types, preparation and method of application; detailing of the preparation steps of the fabrics and thread for receiving the dyes and dyeing. The research was based on reports of women with tradition in the use of vegetable dyes, bibliographic research and a participation in a dyeing workshop given by an expert on the subject. In addition to proving the feasibility of obtaining natural paint, this work also aims to warn about the need for replacement of synthetic dyes, which discard large amounts of chemical soluble in rivers, destroy their biotas and cause disease. It should also be noted that the fossil resources from which these dyes are extracted are finite, so it is relevant to consider the choice of natural dyes that are renewable, use less water, energy and pollutants.
