- Sulphur black belongs
to the group of sulphur dyes.
- Sulphur black is
Lustrous Grains, Imparts full black shade with a slight reddish or
greenish tone according to the requirement.
- Sulphur dyes are a
class of dyes having the best light fastness and low price among the
dyes applied to natural fibres.
- Spectrophotometry
methods are the most applied ones for sulphur dyes quantitative
determination during dyeing process.
- Alkali metal thiolate
is usually necessary as a reducing agent in the dyeing process of
sulphur dyes.
- The general
disadvantage of the Sulphur dyes that they produce dull shades and lack
a red. The main advantage lays in their cheapness, ease of application
and good wash-fastness.
- Although sulphur dyes
are prepared from varied types of intermediates and other varied
conditions, their chemical reactivity and dyeing properties are very
similar.
- For every pound of
sulfur black dye produced, 1.11 pounds of co-product are produced. This
co-product is composed of 0.60 pounds of 25% sodium thiosulfate, 0.38
pounds of 75% sulfuric acid and 0.13 pounds of 20% ammonium sulfate
- Biproducts are to be
taken care of to avoid environmental issue
- Sulphuric acid need
to be purified
- The addition of the
sodium thiosulfate to the wastewater was causing several problems with
the treatment system
- Discharging the
ammonium sulfate to the wastewater system would cause significant
compliance problems
- There is good demand
of about 10,000 MT in India and domestic production seem to be only 50%
- There is import from
China
- About 100 tons/year
project may require an investment of about INR 5 millions according to
some consultants
