Thies Launching Disruptive Dyeing Technology At ITMA
Germany based manufacturer of textile dyeing machine, Thies and which has a legacy going back to more than 130 years will be launching Signature Series at ITMA 2023 in Hall 11, Stall B208.
Thies says the Signature Series will prove to be both disruptive and seamless, but is also ready for existing dyeing mills to use immediately.
With its novel ability to precisely dose concentrated chemistries, and flexibly use less water to transport fabric, the Signature Series is capable of delivering highly consistent results with liquor ratios starting at 1:2.3 liter of water per 1 kg of fabric.
“Proven in bulk production, water consumption is tremendously reduced, dyeing uniformity is improved and batch times are shorter,” the company adds.
According to Thies, due to Signature‘s ultra-low liquor ratio, dye consumption is reduced up to 20% while achieving the same shade, less energy is required for heating water, and the treatment of water is less costly because the total dissolved solids (TDS) is reduced up to 50%.
Unlike pad or spray dyeing, with Signature there is no need to have separate machines for washing, bleaching and dyeing, because nearly all wet treatments can be carried out on this single machine.
There is also no intermediate handling and drying, and there is no end-to-end variation associated with wet-on-wet pad-bath dilution.
Colour uniformity is improved over pad dyeing because fabric passes through the nozzle 60+ times versus a single nip, and there is no side-center-side variation caused by pad roll wear or crowning.
A wide array of various fibres and fabric structures can be successfully processed, including woven fabrics, warp knits, spacers, and circular knits.
Thies is also offering several tools for digitalisation, reporting, and process control like energy control, pH-control and conductivity measurement.
Visual representations of the process curves enable both a control of the turbidity and a determination of the dye extract from the liquor. By measuring the process and providing intuitive reports that aid decision-making, Thies makes dyeing less art and more science.
The company is also showing an automated storage, weighing and dispensing system for dyestuffs or auxiliary chemicals, which comes with many advantages.
Workers no longer have routine contact with chemicals and dyes during weighing, transportation, dispensing, and dosing. Tasks that do not add value are eliminated, and the workplace is safer.
More importantly, the dangers of spilling chemicals and dyes are minimised, protecting workers and the environment from harm.
The digital storage system manages the exact stock levels and generates order proposals if the stock falls below the defined safety level.
