Fourteen grams of acid dye from De Amsterdamse Steek in a wide variety of colors.

Acid dyes are dyes suitable for dyeing protein fibers, such as wool and silk. The dyes are selected for De Amsterdamse Steek on responsible production and color intensity. We use several types of acid dyes and occasionally mix our own color combination. Acid dyes are so-called low-inpact dyes. Heat and an acid environment (light household acids such as vinegar or citric acid) create a final connection between color molecule and protein structure.
