Stop relying on the dyeing rule of thumb, Tanatex says
06/01/2020
In comments at the start of the year, the company’s business development manager for classical textiles, Harald Gruenewald, said working with laboratories to calculate the precise dyeing time required for the specific machine type, water quality, dyestuff, auxiliaries and dyeing method a dyehouse uses, taking into account the fibre mix in the fabric it has to dye, could save up to 10% of the standard 200-minute dyeing cycle.
Mr Gruenewald said many dyehouse managers and technical engineers have had to come up with their own rules of thumb to make sure their dyeing processes can cope with all the variables customers might impose. He explained that, if dyehouses are willing to let these practices go, they will be able to speed the process up and make savings in time, energy and water consumption.
“Focus on your specific situation,” he said. “Which machines and dyestuff do you use? What type of auxiliaries do you add? Do you work with blends or with 100% polyester? You’ll be surprised what 20 minutes can do for your business and carbon footprint.”
