The final evaluation after several months of intensive head-to-head testing by Turkish yarn manufacturer Iskur has shown that the TC 19i from Trützschler offers higher production and more constant quality with less waste in comparison to a high- performance card from a Swiss competitor.
During the tests, carried out by the Iskur Group, Kahramanmaraş/Turkey, the aim was to achieve the maximum possible production with best possible quality and operating costs. The TC 19i from Trützschler Group SE, Mönchengladbach/Germany, showed significantly less unnecessary fiber waste of more than 4%, whereby the comparative cost savings amount to approx. US$160,000/year. This also includes other aspects like energy consumption and maintenance expenses. In the trial both cards ran at 180 kg/h in the production of a rotor yarn Ne 6.5 made of a cotton and cotton recycle blend. Both competitors achieved comparable quality (IPI) now, and the final fabrics both matched the customer’s expectation.
In the second trial, the production target was increased to 250 kg/h. After some adaptations the competitor card now ran at comparable waste levels like TC 19i. However, IPI results of TC 19i were about 30% lower, yarn breaks about 60% lower, and clearer cuts 45% lower. TC 19i produced about 850 kg more in the same time period.
The TC 19i provides high production with good quality and waste removal, as well as lower energy consumption in direct comparison. Permanent, automatic optimization of the carding gap during production and the automatic recognition and setting of waste removal leads to better results.
