Sustainable and intelligent: The TC 19i sets the benchmark for carding
Sustainable and intelligent: The TC 19i sets the benchmark for energy-efficient carding. Global energy consumption reached a record high in 2019, following a 40-year trend for rapidly increasing energy demand that was only halted by the Coronavirus pandemic.1 It’s estimated that more than 80 % of this energy is still generated from fossil fuels that produce CO2 emissions and contribute to climate change.2 Renewable energy offers a solution to this problem, but saving energy whenever possible is an even more effective approach. That’s why Trützschler has developed the intelligent card TC 19i, which sets a new benchmark for energy- efficient carding. Only the intelligent Trützschler card TC 19i features the unique T-GO gap optimizer, which continuously and automatically monitors and adjusts the carding gap to an ideal position during production. By now, more than 2000 intelligent cards sold worldwide prove quality and production leaps in the double-digit percentage range daily, thereby reducing energy demand per kilogram produced.3 Innovative drive- nd air technology further reduce energy consumption of the TC 19i. In this way, the TC 19i saves energy to help protect the planet – and also boosts profitability for yarn production. The most energy-intensive elements in a carding machine are the drive, the dust suction process and the compressed air system. Permanent suction is needed to remove dust and cotton waste in key places. In contrast to Trützschler cards, many cards on the market also use compressed air for suction hoods in the pre-carding and post-carding areas, for example. Smart optimization of these areas has made the intelligent card TC 19i a benchmark for energy efficiency in carding because it uses less electricity, lower suction pressure and less compressed air than other machines, while providing the highest production rates currently available on the market.
All of our air collectors, for example, are carefully developed to eliminate potential resistance and facilitate an ideal flow.” This improvement was made possible by a long and sometimes challenging innovation process involving mathematical models of air flows, as well as flow simulations and prototypes. By combining the final flowoptimized parts in the TC 19i, Trützschler’s experts have developed a card that operates with suction pressure of just -740 Pa and with an air requirement of only 4200 m³/h. This translates into 40 % less energy demand for air technology compared to the latest high-performance competitor model. “These achievements are fantastic – but we didn’t stop there,” says Ralf Helbig, R&D Engineer for Air Technology at Trützschler. “We have also made it possible to further reduce energy demand in polyester applications, which are increasingly important to our customers. In a polyester configuration, the TC 19i can reduce the necessary pressure for waste suction by a further 14 % because of improvements to elements in the pre-carding and post-carding areas, and the removal of suction hoods. The suction is still just as reliable – but it needs much less energy.”
