Nature of
Reactive ‘HE’ Brand Dyes :
(Bis-Monochlorotriazine
Class)
These Dyes are mostly suitable for
dyeing on Cotton and Other Cellulosic Materials. They have
significantly higher exhaustion and fixation efficiency, which
helps in cost reduction to conventional reactive dyes. The high
fixation and good build up are of particular importance with
polyester/cellulosic blends and wash liquor. The ratio is very
high. Higher fixation drained and washes liquors after dyeing,
contain much less unfixed dyes, compare to conventional Reactive
Dyes. It is useful when pollution control is a major concern.
Also facilitates quicker wash off and efficient soaping. The
improved stability offers batch consistency. Exhaustion is
controlled by salt addition and temperature by level dyeing,
prior alkali addition.
Prominent features are as per below mentioned:
-
Excellent build-up Due to low liquor to Good ratio.
-
High fixation is of importance as dyeing polyester/ cellulose
blend when liquor/goods ratio is quite high. Conventional
reactive dyes show low dyeing efficiency and poor build-up in
similar condition.
-
Superb reproducibility.
-
Wide applicability on loose stock, garments, yarn and piece
material.
-
Wide choice of equipment to suit particular application.
