Econtrol®

With the trend towards smaller lot sizes per colour in continuous dyeing and the requirement for simple processes, the Econtrol process for reactive dyestuffs was developed in the mid-nineties. It has now established itself with DyStar technology worldwide.

The Econtrol® process is a simple, quick and economical one-pass pad - dry - wash off continuous dyeing process with drying in a hot flue at 120-130° C and controlled humidity (25-30% by volume) to obtain fixation in 2 - 3 minutes.

Benefits

	Ideal choice for short or long lot dyeing
	Full colour range
	Excellent reproducibility of colours
	No risk of browning of cellulose fibres thanks to low fixation temperature - bright colours possible
	No urea - no fumes - no machine contamination
	No salt (easy wash-off of unfixed dyestuff)
	Instant colour viewing
	Accurate, easy and rapid laboratory check method
	No unproductive batching sequences, no moiré effects
	Migration minimised by rapid fixation and humidity control
	No crushing of pile fabrics (e.g. corduroy)
	Improved penetration of difficult fabrics due to presence of humidity during fixation
	Energy-efficient thanks to optimum humidity control
	Ideal process for fast change technology
