The TC19i: A new benchmark for man-made fiber processing

Man-made fibers are durable, versatile and cost-effective. That’s why they have become indispensable in yarn production over the past decade and now account for more than 40 percent of staple fiber consumption. Truetzschler has supported this trend by developing highly specialized machines for man-made fibers that meet constantly rising expectations for quality and efficiency – and the TC 19i is now winning over customers worldwide.

The intelligent card TC 19i for man-made fibers was launched in 2019 and is now the international benchmark for man-made fiber processing. The results from major textile markets across Asia, Europe and the Middle East speak for themselves: customers were able to increase productivity by between 20 and 100 percent, while also improving quality (IPI) by between 20 and 55 percent.

Turning skeptics into believers

Acarsoy Tekstil, a leading yarn manufacturer based in the Bursa province of Turkey, is a strong example of what can be achieved with the TC 19i for man-made fibers. The company has a daily production capacity of 65 tons of yarn across two production facilities, and manufactures a broad portfolio of cotton, linen, polyester, viscose, modal and lyocell yarns. Its processes include ring, compact, air jet, open end, core spun and siro spun technologies. Experts at Acarsoy Tekstil were initially skeptical when Truetzschler TC 19i cards were installed in the second air jet line for 100-percent viscose yarn (Ne 20 to 28). General manager Bülent Değirmencioğlu, as well as his team of operations and maintenance managers, were unsure whether the required level of quality could be maintained when the TC 19i operated at such high speed. However, they were able to produce 60 percent faster with the TC 19i, and clearer cut numbers were 50 percent lower than the first line. In light of these impressive results, Acarsoy is now considering modernizing its other machines too.

 

“Cards are the beating heart of the spinning mill,” says Bülent Değirmencioğlu (pictured in the middle). “We know we’ve made the right choice with the TC 19i for man-made fibers because it’s taking our superior quality to the next level – while also cutting waste, reducing energy consumption and saving labor costs.”

 

 

 

Major improvements across all man-made fiber applications 

Every single one of the manufacturers that tested the TC 19i for man-made fibers has been able to increase productivity and reduce yarn imperfections compared to predecessor machines. Of course, individual results vary depending on the customer’s specific application, raw material and process – but the TC 19i achieved success every time. This success is largely made possible by the T-GO gap optimizer, which has been specifically adapted to meet the requirements of man-made fiber applications.

“For cotton processing, a very narrow carding gap is often advantageous for the carding result – but this doesn’t apply to man-made fibers” says Christoph Leinders, who was responsible for the design of the TC 19i. “Our T-GO gap optimizer uses advanced, intelligent sensor technology to make sure the machine always maintains the best possible carding gap for the man-made fiber material, blend or application that is being processed. This gives the TC 19i a big advantage over machines from our competitors. We always know the exact carding gap and can adjust it during production using algorithms that we specifically developed for man-made fibers. This means changing environmental conditions or differences in the skill level of the individual operator
no longer affect the carding gap setting – so quality levels remain constant.” The T-GO gap optimizer for man-made fibers is as easy to operate as its counterpart for cotton. Only a few clicks on the display are required, and there’s no need for time-consuming flat setting work after each maintenance or re-clothing.

A winning combination of new and proven features

The excellent performance of the TC 19i for man-made fibers is made possible by several new and proven features. The doffer clothing NovoDoff 32, for example, has been specifically developed for man-made fibers by Truetzschler Card Clothing, a subsidiary of Truetzschler that is located in the Black Forest region of Germany. Its engineers invented a new process technology that makes the clothing even more robust and durable, and further improves quality while reducing maintenance requirements. Of course, the new card retains the outstanding features that have proven their performance in man-made fiber applications over many years. All metal sheets in the tuft feeder and the transfer section to the card are made of stainless steel to ensure an optimal flow of man-made fibers. All covering elements for the cylinder and doffer are made of high-precision, eloxated aluminum. A stainless-steel sliver coil tube and coiler plate ensures gentle sliver guidance during sliver coiling. And the pre-opener system of the TC 19i features one large roll with a special needling and surface treatment. This makes it possible to reduce yarn imperfections (IPI) by up to 30 percent compared to rolls with conventional wires, while the average lifetime of the needle roll is twenty times longer than a conventional roll. As man-made fibers gain importance for yarn production, the TC 19i is a powerful new card that delivers valuable performance across a wide range of applications. Customers at spinning mills around the world are taking advantage of this new benchmark for man-made fiber processing – and moving ahead of their competitors by increasing productivity, efficiency and quality.
