What are the differences in dye toxicity between fabric types?

The toxicity of dyes varies significantly depending on the type of fabric they are applied to. Synthetic fabrics like polyester and nylon often require harsh chemical dyes, which can contain toxic substances such as azo dyes or heavy metals. These chemicals may leach out over time, posing health risks like skin irritation or even long-term toxicity.

Natural fabrics like cotton, linen, and wool typically use milder, plant-based or low-impact dyes, which are less toxic and more environmentally friendly. However, even natural fabrics can be treated with harmful chemicals if not sourced responsibly.

To minimize exposure to toxic dyes, opt for organic or OEKO-TEX certified fabrics, which adhere to strict safety standards. Always wash new garments before wearing them to reduce residual dye chemicals. By understanding these differences, you can make safer choices for your wardrobe and the planet.
