Dyes in printing and dyeing auxiliaries are not unfamiliar to us, and they are inseparable from our lives. Simply put, dyes can be divided into two types, one is chemical dyes and the other is environmentally friendly dyes. Chemical dyes are dyes made from a series of chemical reactions or direct use of colored chemical substances. Environmentally friendly dyes are different. Environmentally friendly dyes are obtained from some plant, animal or mineral resources, and almost no chemical processing.

Dyes are widely used. Like the clothes we usually wear, colorful clothes are realized through dyes. Most of the dyes used in clothes are chemical dyes, but the content of harmful substances is up to the standard, but some people with sensitive skin may still have allergic reactions. Environmentally friendly dyes are different. Clothes dyed with environmentally friendly dyes are softer and will not cause allergic reactions to the human body.

Dyes are not only in the clothing industry, some plant dyes are derived from medicinal plants, so they are also widely used in health and medicine. Natural dyes are also used in the manufacture of cosmetics, such as enhancers in lipsticks, skin beautification, and dyes in hairdressing products. Natural dyes are non-toxic and harmless, and are non-allergenic and carcinogenic to the skin, so we try to choose some environmentally friendly dye products when we choose.
