About Sulfur Dyes There are many types of dyes and they vary widely in chemical composition. Sulfur dyes are classified as dyes that can be applied to fiber, yarn or fabric. The other types of dyes used are:
- vat dyes,
- azoic or ice dyes,
- direct dyes,
- developed or diazo dyes,
- basic dyes,
- acid dyes,
- chrome dyes, and
- dispersed dyes.
Sulfur dyes are insoluble in water and must be chemically treated to reduce them to a soluble form. When applied to a fabric, sulfur dyes oxidize when exposed to air and heat which convert the dye to an insoluble form. Sulfur dyes are used to dye cellulose fibers, including cotton, linen, and rayon. Sulfur dyes are comparatively low in cost and are largely used for production of goods in dull and darker shades. The range of shades which can be produced with sulfur dyes is limited to dull shades of yellow, brown, tan, khaki, green, maroon, blue, gray, navy and black. Any type of wearing apparel for men, women and children can be sulfur dyed. Household fabrics can also be sulfur dyed.
