The dyeing type of fabric, after dyeing, the outside is colored and the inside is white (the primary color of fabric). Is dyeing good for people's health?

There are many kinds of fabric dyeing, including but not limited to reactive dyes, disperse dyes, acid dyes, direct dyes and so on. Among them, reactive dyes are widely used environmental protection dyes, which have the advantages of high color strength and little pollution. Direct dye is a kind of traditional dye, which has the advantages of bright color and high light resistance.

For dyed fabrics with outer color and inner white, white core or two-color core process is usually adopted. In the production process of this kind of cloth, white yarns or fibers are interwoven with colored yarns or fibers to form two different colors of cloth. In the dyeing process, only the outside is dyed, and the white core or the double-color core inside is not affected.

As for the influence of dyeing on human body, it depends on the kind of dyes used and the dyeing process. Some dyes and dyeing processes may release harmful substances, posing potential risks to human health. However, for dyes and dyeing processes that meet environmental standards, the release of harmful substances is low, which has little impact on human health. Therefore, when buying dyed fabrics, we should choose brands and products that meet environmental standards.
