Sulfur
dyes are high molecular weight compounds that are obtained from the
reaction of sulfur or sulfides with phenols and amines. There are
many colorants available in the market that contain sulfur however,
only those dyes that are soluble in water after reacting with sodium
sulphide in alkaline conditions are known to be sulfur dyes. The
exact chemical structure of sulfur dyes are not known as the
molecules of sulfur dyes are highly complex in nature. Amino
derivatives, nitro, aminobiphenyls, nitrobenzenes, substituted
naphthalenes, indophenols, azines and oxazine among others can be
part of sulfur dyes.
Sulfur
is an integral part of polysulfide and chromophore side chains
present in the sulfur dyes. Sulfur dyes are insoluble in water
however, under alkaline conditions it gets easily converted into
leuco forms. Sulfur dyes in leuco forms soluble in water and also
exhibit higher affinity for fibers. Sulfur dyes are further converted
into insoluble state after it is absorbed in the fibers. Sodium
hydrogensulfyde and sodium sulfide are generally used in reducing
the sulfur dyes. Sulfur dyes are inexpensive and thus are widely
used in the dyeing industry. Most of the sulfur dyes manufactured are
the sulfur black color which can be widely used in a range of
fabrics. Common salt when used with sulfur dyes acts as a catalyst
which facilitates the absorption process. Sulfur dyes find major
applications in the textile industry.
Increasing
population coupled with rising disposable income is expected to boost
the overall growth of textile industry. Growing textile industry is
expected to further augment the overall demand for sulfur dyes.
Sulfur dyes are one of the most abundantly used dyes in the textile
industry. Most of the sulfur dyes manufactured are used in the cotton
textile industry. In addition, easy availability of sulfur dyes at
cheap price makes it a suitable choice as an alternative for most of
the dyes. Sulfur dyes are inexpensive, cheap and can be washed as
well as applied easily.
Owing
to the presence of many benefits the overall demand for sulfur dyes
is expected to grow in the near future. In addition, sulfur dyes
exhibit excellent bleaching properties making it a suitable dye in
the textile industry. However, growing environmental awareness
coupled with presence of stringent government regulations is expected
to restrain the overall growth of the market. Sulfur dyes are known
as an effluent contaminant and hence, their use in restricted to some
extent. Thus, the toxic properties of sulfur dye are expected to
hamper the overall growth of the market.
Asia
Pacific is expected to be the largest producer as well as consumer of
the overall sulfur dye market. China is expected to be the largest
manufacturer of sulfur dye mainly owing to the presence of large
number of small scale manufacturers in the country. Rest of the World
is expected to gradually grow as the consumer of sulfur dye. However,
the sulfur dye market is anticipated to grow at slow rate owing to
the presence of stringent regulations in Europe and North America.
Venus
Dye Chem, Sinochem tianjin Co., Ltd., Qingdao Sanhuan Colorchem Co.,
Ltd. and ABS LABORATORIES are some of the major participants in
sulfur dyes market. The company’s mainly strive to increase their
production efficiency and also to develop environmental friendly
bio-based products to achieve competitive advantage.
