Monforts Textilmaschinen GmbH & Co. KG will launch a revolutionary new system for yarn dyeing based on the proven Econtrol® dyeing system for fabrics at ITMA 2019 in Barcelona, Spain, from June 20-26, 2019.
This latest CYD denim processing technology integrates new functions and processes into the weaving preparatory processes – spinning, direct beaming, warping and assembly beaming, followed by sizing and dyeing – in order to increase quality, ﬂexibility, economic viability and productivity.
Econtrol® is a pad-dry process employed in Monforts continuous dyeing in which the reactive dyestuff is fixed to the cellulose fibres during drying and the CYD multi-colour yarn dyeing system introduces a number of new concepts based on it, including the unique Eco Bleach process.
This is the first bleaching system for yarn treatment available on the market and will be of particular interest to denim manufacturers. The Eco Bleach system is combined with the washing units and the fabric is then dyed immediately, resulting in considerable savings in waste water and chemicals.
The most effective dyeing process for fabrics is now being applied for yarn dyeing and it is possible to process short batches of between 5-10,000 metres of yarn in order to produce 2-300 metres of fabrics in a single continuous process.
In its raw state, cotton has a light brownish/yellow tinge and bleaching is necessary to ensure its pure whiteness prior to dyeing. On conventional systems, this involves a separate process step, but with the CYD multi-colour yarn dyeing system it is now integrated into the Econtrol® process for full dyeing pre-treatment.
