For many years Cushing’s Perfection Dye was a “union” type dye, designed to be suitable for a variety of plant, animal and synthetic fibers. In response to the changing availability of raw materials and to increase the effectiveness and ease of use of our dyes, we reformulated them into two types, acid and direct. Acid dyes are suitable for wool, mohair, and nylon. Direct dyes are the better choice for cottons and cellulose materials, plus linen and rayon. Silk dyes best with one type or the other, depending on the particular characteristics of the silk.
The contents of one package will dye one pound (dry weight) of material to the full shade. Use more or less for deeper or weaker shades.
