Dyeing process

Econtrol^®

Dyeing with reactive dyestuffs

Econtrol^® is a simple, fast and economical single-step dyeing process for reactive dyestuffs – at process temperatures of 120 to 130 °C, with a controlled humidity content of the circulating air of 25 to 30% by volume and a dwell time of only 2 to 3 minutes.

The advantages at a glance:

• Ideally suited for dyeing short or long batches
• All colours can be selected
• Excellent colour reproducibility
• No risk of yellowing in cellulose fabrics due to low fixing temperature. This also allows light colours to be used.
• No urea – no fume development – no deposits
• No salt (easy to wash out)
• Immediate colour assessment
• Precise, easy and quick laboratory settings
• No dwell time required, no Moiré effects
• No migration due to fast fixing
• Moisture control
• No crushing of pile fabrics (e.g. corduroy)
• Better penetration even of difficult items thanks to the controlled chamber climate during the dyeing process
• Energy savings thanks to optimum moisture content of the process air
• Ideal process for frequent batch changes

Econtrol^® T-CA

Single-bath dyeing of PES/CO

Econtrol^® T-CA is the innovative continuous dyeing process for PES/CO fabrics – using selected reactive and disperse dyestuffs in a single process step, based on the pad-Econtrol-thermosol process – completely without reductive intermediate cleaning. That allows you to save a significant amount of chemicals, water, energy and time.

The advantages at a glance:

• No steamer required
• Low chemical consumption (up to –86%*)
• Low energy consumption (up to –49%*)
• Low water consumption (up to –63%*)
• Lower investment costs
• Less personnel required
• Good fabric colour-fastness
• Very simple process
• Very low costs
• Ecological advantages
