-
Select dyestuff
that do not contain Chlorinated benzene and toluene.
-
Avoid using Carcinogenic
dyestuffs in your combinations.
-
Avoid using
Allergic dyestuffs ( some selected disperse dyes are allergic).
-
Do not use
chelating agents that contain phosphates.
-
Use APEO and NPEO
free surfactants as dispersing agents.
-
Ascertain that
your surfactant do not contain any ethoxylated products.
-
Use Formic acid
for neutralization purposes rather than Acetic acid.
-
Do not use formaldehyde
containing dye fixing agents after reactive/direct dyeing.
-
Use Natural dyes
can be used and that do not have heavy metals etc, give the first
preference.
-
Most important is
to control and limit the use of water for all purposes.
-
If reactive
dyeing is carried out, where ever possible go for low salt and no salt
dyeing/trials.
-
Avoid
reprocessing, save energy, money and water.
-
Try and establish
a system of Right
First Time practice in dyeing.
-
In reactive
dyeing, where ever possible you may try cold dyeing to save energy. Preconditioning
method is one such procedure.
-
In disperse
dyeing avoid using phenolic carriers. Select dyestuffs carefully.
-
In wool and silk
dyeing metal complex dyes' selection should be optimistic.
-
In all cases of
wet processing, establish a suitable system of water recycling either with
an R.O.system or Nano System.
