STANDARDISING THE SAMPLE PREPARATION FOR ANALYSIS OF FIBRES AND PARTICLES BY STATIC IMAGE ANALYSIS

Static 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.
