Improved quality for nonwovens made from high-performance fibres and longer lifetime due to optimised card clothing and adapted online control as well as integration of the online wear analysis into the process and developing of an industrial adapted version

As part of the futureTex project HPF Garnitur, a digital monitoring system was developed that analyses the wear of card clothing. In the sense of Industry 4.0, this enables maintenance-optimised process control, so that the necessity of the upcoming clothing change can first be checked online.

The structure of the project consortium made it possible to observe different clothing conspicuities caused by the processing of high-performance fibres. In addition to pollution of the cylinders, which occurs in particular with opening cylinder, different types of wear and damage could be identified. The focus of the investigations was on main cylinder as well as stripper and worker clothing. In addition, random rollers and transfer cylinders were examined in more detail.
