      any of a group of sulfur-containing, complex synthetic organic dyes applied from an alkaline solution of sodium sulfide (in which they dissolve) to cellulose, where they become substantive to the fibre. On exposure to air, the dyes in the fibre are oxidized back to their original insoluble form. Sulfur dyes are fast to washing, perspiration, and light but have poor resistance to chlorine bleach. Most colours are available, especially subdued and deep shades, rich blacks, and navy, but not bright red and orange.
