| Pretreatment |
The pretreatment of yarns and fabrics prior to dyeing is a
science in itself. Before a fiber will take a dye, everything
in it has to come out - all the natural soiling and all the
upstream processing aids, such as finishes, lubricants and
sizes.
From desizing through washing and boiling-off to mercerizing
and bleaching, pretreatment involves more than just cleaning.
Nothing goes without chemicals. Surfactants to wash out water-soluble
and emulsifiable substances. Persulfate or enzymes to degrade
starch. Alkalis to bind soil, make it dispersable and emulsifiable.
Hydrogen peroxide to remove discolorations.

Systems for Optimal Effects |
When it comes to combining all these elements into efficient
chemical systems, Chromatex is your ideal partner. With our
comprehensive understanding of the processes, excellent laboratory
skills and engineering knowledge about the machinery and equipment,
materials, and the possible error sources, we help you to
achieve optimal metering, control and process-linking of the
individual pretreatment stages.
Whether the process is continuous or discontinuous, irrespective
of the make-up, we will define the optimal combination of
auxiliaries and agents. Natural, biodegradable substances
come first every time in developing our products. This is
how we guarantee optimal effects with minimum stressing of
materials and minimum wastewater loading.

Whole Spectrum of Specialties |
Specialty number one: continuous pretreatment of cotton and
cotton mixes. Products such as Clean-SR, Stab-CT, Dura - MRC
and Sequest - LS stand out for their low foaming, rapid wetting
and optimal emulsification - and have made us a global market
leader.
Specialty number two: processing aids for mercerizing cotton.
Foam-free processes with biodegradable products such as Bin
- LR and Sequest - LS improve the dye uptake, luster and processing
properties.
Specialty number four: wool pretreatment. Our detergents based
on natural raw materials are especially gentle. Det - CD,
Det – CD550, Wetsol - LFD and various products preserve
fiber elasticity during the raw wool wash and optimize processing
during dyeing.
