	Reduction of sulfide in effluent from sulfur black dyeing (Site not responding. Last check: 2007-10-16)
		Sulfur dyes are an important range of dyes yielding a range of deep colors, but they cause a pollution problem due to the traditional reducing agent used with them.
		Sulfur dyes are water insoluble compounds that have to be converted during the dyeing process first into a water-soluble form and then to a reduced form to enable fixing of the dye on the fiber to be dyed.
		The dyeings obtained after this substitution were seen to be equivalent to conventional dyeings in depth of shades, fastness properties, etc., plus there were some other improvements in the quality of the dyed products.

	Sodium thiosulfate - Wikipedia, the free encyclopedia
		The thiosulfate anion is tetrahedral in shape, and is notionally derived by replacing one of the oxygen atoms by a sulfur atom.
		It is also used in the tanning of leather, in chemical manufacture, in bacteriological water assessment, and in treating cyanide poisoning.
		It is also produced from the action of sodium sulfite on sulfur in aqueous solution.

	Image-recording materials with 1,3-sulfur-nitrogen dye releasers
		The presence of two cyclic moieties mandates that two silver ion assisted cleavage reactions occur prior to release of the dye or dye intermediate, thus, a desirable decrease in non-specific release of the dye or dye intermediate is effectuated.
		Complete dyes which may be used in the present invention include any of the general classes of dyes heretofore known in the art, for example, nitro, thiazole, cyanine, di- and triphenylmethane, anthrapyridone, azo such as shown in examples IV and V herein, anthraquinone, phthalocyanine and metal complexed azo, azomethine and phthalocyanine dyes.
		The dispersion was diluted with water during isolation of the dye from the beads to a concentration of approximately 20%.

	Vat dye and sulfur dye compositions
		These can be added to a vat dye or sulfur dye composition, or to a dye bath or printing paste containing a vat dye or sulfur dye, by virtue of which an improvement of dye yield, particularly on cellulose materials, is obtained.
		There are known numerous processes in which the dye yield when cellulose materials are being dyed or printed with vat or sulfur dyes is improved by the addition of specific vatting accelerators, usually oxidising agents.
		Suitable vat dyes and sulfur dyes are for example: indanthrones, flavanthrones, pyranthrones, violanthrones, isoviolanthrones, benzanthrones, imides of perylenetetracarboxylic acid substituted on the nitrogen atom, acridones, anthraquinone oxazoles, anthraquinone thiazoles and compounds which are derived in particular from anthraquinone.

	Procter and Gamble introduces Sulfur Dye Protection technology - Dyes & Chemicals - Express Textile
		Sulfur Dye Protection Technology, a P&G innovation has shown potential to significantly improve color fastness and reduce damage to fabrics used by millions of people around the world.
		Sulfur dyes are typically used to inexpensively produce fl, brown, navy and olive colored fabrics.
		A primary problem with sulfur dyes, and a significant factor in their recent decline in usage, is the relatively poor color fastness of the fabric when laundered.

	Image-recording materials with cyclic 1,3-sulfur-nitrogen dye providing compounds
		The dye-providing compounds are capable of releasing the coupler dye upon cleavage in the presence of silver ions or a soluble silver complex.
		Useful dye radicals to be used in the dye-providing materials for photographic and particularly for photothermographic applications, are coupler dyes, i.e., dyes formed by the oxidative coupling of a phenylene diamine with a color coupler, e.g., azomethine, indoaniline, indamine, and indophenol dyes, as disclosed in the copending U.S. patent application, Ser.
		The aminoethylthiazolidine dye used in the preparation of the compound of formula (xiii) was prepared by a procedure analogous to that used in step (d) of Example 1 using the aldehyde coupler dye of formula (iv) in place of the dialdehyde coupler dye and 1,1-dimethyl-2-(2-amino)ethylaminoethanethiol in place of (N-octadecylamino)-2-methyl-2-propanethiol hydrochloride.

	Specialty Chemicals Textile Chemicals Indigo Dye
		To replenish the indigo and chemicals used by the continuous passage of yarn through the dye bath, a dye feed and a chemical feed are used.
		Dye feed mix consists of Indigo, Sodium Hydroxide, VIRCOTONE QS-424 and sodium hydrosulfite.
		Typically, in the dye feed just enough chemicals are used to keep indigo in a reduced state, therefore, excess chemicals needed in the dyebath are supplied from the chemical feed.

	TIME LINE OF FABRIC INFORMATION (Site not responding. Last check: 2007-10-16)
		In the latter half of the 19th century new processes arising from the discovery of an increasing number of new dyes led to improvements in the design of reaction vessels, autoclaves, pumps for the transfer of liquids, compressors, and vacuum pumps.
		Dyes applied in this way are called developed dyes; para red and primuline red are members of this group that were introduced in the 1880s.
		With the introduction of reactive dyes, cotton could finally be dyed in bright shades with monazo dyes for yellows to reds, anthraquinones for blues, and copper phthalocyanines for bright turquoise colors.

	EPA: Federal Register: State of Alaska Petition for Exemption From Diesel Fuel Sulfur Requirements
		If none of that fuel were dyed and the sulfur exemption were to expire, the tax liability for Alaska (at 24.4 cents per gallon) would be approximately $146.4 million per year, compared to only $19.4 million per year if only that fuel used for highway purposes were taxed.
		Conversely, EPA will not require high- sulfur diesel fuel to be dyed if it is being shipped from the lower-48 states to Alaska, but supporting documentation must substantiate that the fuel is only for shipment to Alaska and that it may not comply with the sulfur standard for highway vehicle diesel fuel.
		However, if subsequent to today's document, the Administrator determines that supplies of low sulfur diesel fuel are inadequate to meet the requirements of new technology diesel engines and that significant environmental harm is resulting from adverse impacts of high sulfur diesel fuel on these vehicles, this exemption may be reconsidered.

	Cotton Incorporated - Lifestyle Monitor Denim Issue - September 13, 2005
		Among the latest trends is the use of a recently developed generation of sulfur dyes.
		If a sulfur dye of a color other than indigo is used in the first vat, it’s called ‘bottom’ sulfur dyed; if it’s used in the last vat, it’s called ‘top’ sulfur dyed,” he explains.
		Black was the original sulfur color, but we’re starting to see the development of new tints, including shades of green, which are expected to be in stores this fall.
