At ITMA 2019, Monforts introduced a revolutionary new system for yarn dyeing based on the Econtrol dyeing system for fabrics.
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.
“Denim finishing is a field in which Monforts has an undisputed lead and we have been working closely with our many partners in the key denim manufacturing countries of China, Bangladesh, India, Pakistan, Mexico and Brazil to develop new advanced solutions,” says Monforts’ Head of Denim, Hans Gerhard Wroblowski.
“The CYD system has been developed in response to very strong market demand,” added Hans Gerhard.

According to the company, Econtrol is a pad-dry process employed in Monforts continuous dyeing in which the reactive dyestuff is fixed to the cellulose fibers during drying and the CYD multi-color 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, says Monforts.
The Eco Bleach system is combined with the washing units and the fabric is then dyed immediately, resulting in considerable savings in wastewater 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 5-10,000 meters of yarn in order to produce 2-300 meters 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-color yarn dyeing system, it is now integrated into the Econtrol process for full dyeing pre-treatment, the company adds.
