We
offer a range of salt free dyes that are extremely eco -friendly and have
excellent fastness properties. These dyes exhibit excellent dye exhaustion
and have improved dye fixation properties. Our range of salt free dyes are
manufactured using membrane technology and find utility in Inkjet Industry.
Salt and other impurities are removed from the dyes, which improves product
solubility. Our array of Salt Free Dyes include:

* WATER BASED INKJET / PRINTING DYE
Reactive dyes are a group of colored organic substances
that are primarily used for tinting textiles. They attach themselves to
their substrates by a chemical reaction, forming a covalent bond between the
molecule of dye and that of the fiber. Hence, the dyestuff becomes a part of
the fiber and has low possibility to be removed by washing than the
dyestuffs that adhere by adsorption.
The reactive dyes were designed for cellulose fibers for the very first
time, and are still used in this way in most cases. Fiber Reactive Dyes are
also commercially available for protein and polyamide fibers. Theoretically,
these dyes have been developed for other fibers, but practically they are
not yet commercial. The reactive dyes contain a reactive group, which when
applied to a fiber in a weak alkaline dye bath, formulates a chemical bond
with it. These dyes can also be used to dye wool and nylon. In the case of
nylon, they are applied under weakly acidic conditions.
The vital characteristic of the reactive dyes, is the formulation of
covalent bonds with the substrate to be colored. These dyes form a chemical
bond with cellulose, which is the main component of cotton fibers.
These fiber reactive dyes are the most permanent of all types of dyes.
Unlike other dyes, these reactive dyes form a covalent bond with the
cellulose or protein molecule. Once this bond is formed, a whole molecule is
formed, as the dye molecule has become a part of the cellulose fiber
molecule. Hence, garments that have been dyed in bright fiber reactive
colors, can be safely washed with white clothing, a number of times, without
damaging the whites. In comparison to all the other dyes, these reactive
dyes chemically bind to the textile fibers, which significantly improves the
product's colour stability and wash ability. Thus, reactive dying of cotton
is presently the most widely used textile dying process in the world.
