- ItemONLINE WEAR ANALYSIS OF CARD CLOTHINGS(Technical University of Liberec, ) FISCHER, HOLGER; HEILOS, KATHARINA; THAL, DANIEL; FAASEN, ANDRÉ; HOFMANN, MARCEL; Technická univerzita v LiberciThe processing of abrasive fibres in the carding process, in particular high-performance fibres such as glass, carbon or aramid fibres, can cause increased wear of the card clothing. In the FutureTex project ‘HPFGarnitur’, the wear of card clothing was investigated and an online wear measurement system has been developed. The aim of the project was both, to optimize the clothings to enable gentler processing of the fibres, and to develop a digital monitoring system to observe the degree of wear of the clothings, which offers a new possibility for maintenance prediction and production planning in the sense of Industry 4.0.
- ItemSTANDARDISING THE SAMPLE PREPARATION FOR ANALYSIS OF FIBRES AND PARTICLES BY STATIC IMAGE ANALYSIS(Technical University of Liberec, ) FISCHER, HOLGER; SIGMUND, INA; HARTWIG, PETRA; DEDERER, ESTHER; MASCHINSKI, ANNETT; Technická univerzita v LiberciStatic image analysis is known as a versatile method, which is in use for characterisation i.e. of fibres, nonwovens, textile recyclates etc. Due to incomplete standardization (esp. in the area of sample preparation) the usage is actually limited. Within the project StaPAFaB two research institutes are engaged to compile a reference manual listing typical classes of materials and optimised methods of sample preparation for each of them. This will be combined with recommendations for reasonable parameters in image acquisition / processing and possible limitations for each type of material. Aim is to enable reproducible and consistent analyses on an inter-laboratory level as well as to reduce the demand of time for the analyses. This article focuses on typical classes of textile materials and adapted methods to enable their quick and reliable sample preparation.
