The textile and dyeing machinery manufacturer Thies Textilmaschinen GmbH & Co. KG, Coesfeld/Germany, will exhibit the Signature Series for the first time. The Signature technology transforms existing dyeing systems, but it is plug-in ready for existing dye houses. With its 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 l of water per 1 kg of fabric. Proven in bulk production, water consumption is reduced, dyeing uniformity is improved and batch times are shorter.
Signature’s low liquor ratio has further multiple cost and environmental benefits. 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 no intermediate handling and drying, and there is no end-to-end variation associated with wet-on-wet pad-bath dilution. Color 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 fiber types and fabric structures can be successfully processed, including woven fabrics, warp knits, spacers, and circular knits.
Digitalization and process control
The first steps toward making dyeing a more comprehensible science are measurement and analysis. Thies offers several tools for digitalization, reporting, and process control. Energy control, pH-control, conductivity measurement, and dye control are tools for optimizing recipes and process settings. 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 more scientific.
