Coyuchi Dyeing Process
Low-impact fiber-reactive dyes are synthetic dyes that chemically bond directly to fiber molecules. The fixation or absorption rate of low-impact dyes is between 70-90% creating less waste water runoff and therefore a lower impact on the environment. They also require less water and less heat than other chemical dyes. Recent advances have created fiber-reactive dyes with colors that are brighter and richer, and they provide excellent colorfast properties on cotton. They contain no heavy metals or other known toxic substances, and they meet all European Union criteria for being an eco-friendly pigment. But the actual dyes in almost all low-impact fiber-reactive dyes are still petrochemical based.
Low-impact, fiber-reactive dyes have become the dye choice for many organic clothing manufacturers who want a diverse palette of vibrant colors. Depending upon the nature and degree of their chemical sensitivities, people with mild chemical sensitivities can often wear organic clothing with fiber-reactive dyes. Undyed, natural color or color-grown fabrics are the best choice for people who react to fiber-reactive dyes or who want only pure fabrics on their skin.
