Textiles, a
basic human need has always been a hotspot for innovation. A major modern concern
of producers as well as environment groups has been the fact that textile
coloring processes involve dyes. The discharge processes have a damaging effect
on the environment and involve consumption of large volumes of water.
Furthermore, they are toxic to human health.

Acting on these
concerns, Qualitron is pioneering printing technologies that are free of dyes
and discharge processes without compromising the feel and fastness standards
typical of dyed prints.
Epricon –
Pigment Based Solutions for Reactive replacement
Reactive
printing has been the mainstay of coloring fabrics due to the exceptional
depth, feel and fastness properties imparted. It involves using dying agents,
chromophoric molecules with reactive groups, that react permanently to the
fabric. Reactive printing does not come without drawbacks though. Reactive dyes
require alkaline fixation baths consuming large quantities of water yet do not
fully fix resulting in generation of excess dye contaminated water and dye
wastage. Further, the final color development cannot be ascertained until the
fabric undergoes post processing thus essentially printing “blind”.
Pigment printing
on the other hand involves fixing pigments onto the fabric using polymeric
binders. The process involves preparing pigment pastes consisting of pigments,
binder, thickeners and certain enhancing additives. This paste is then printed
onto the fabrics and cured. There are no post processing steps and the water
consumption is minimized to paste preparation and evaporated away during
curing. There is no effluent stream generated unlike reactive dying.
There have been
several attempts to replace reactive printing with pigment based solutions but
the challenge of obtaining feel and fastness standards still remains. Qualitron
Chemicals, through its Epricon package, has successfully overcome these hurdles
in pigment printing. With wet rub and wash standards like reactive and zero
hand feel, Qualitron is enabling a shift for printers to move towards zero
water discharge printing processes without compromising on print quality. Our
rotary grade ready white inks are designed for highest opacity and hand feel
standards allowing for replacement of discharge printing eliminating water
usage involved.
K2 Inks –
PVC-free Water Based Garment Printing Inks
Qualitron
Chemicals & Pigments is a global pioneer in the shift away from PVC
Plastisol based screen printing ink towards water-based technology. With
increasing environmental and health concerns around the usage of PVC and
plasticizers, there was a need to shift towards more eco-friendly and non-toxic
platforms which called for the usage of PVC free inks . With K2 series of water
based printing ink, qualitron enables manual and machine printing with the
runnability and ease of plastisol and excellent hand feel and fastness
standards. Typical inks compromise between hand feel and wet rub standards.
Qualitron polymer technology allows maximum wet rub standards without losing
the hand feel allowing deep color printing with excellent durability.
