NIR Spectroscopy for Size Identification of Continuous Filament Yarns and Woven Fabrics

J. Holland, Chimitex GmbH, SchopfheimM. Mielke, Technical Textiles Institute Wuppertal of the Acordis GroupJ. M. Marzinkowski, Bergish University GH Wuppertal  
The possibilities and limits of NIR spectroscopy for identifying sizing agents on continuous filament yarns and woven fabrics were explored in terms of sized and desized woven test specimens and of warp and weft ends separated from the fabrics, the NIR spectroscopy method proving to be fundamentally suitable for the qualitative analysis of organic substances applied to yarn and woven fabrics (of sizing agents in this case). An inclusive data base is essential. Unambiguous identification of test specimens, for which a comparison test specimen with similar features is available in the data base, is possible in each case examined. To this end, identical conditions must be ensured in test specimen preparation and make-up.
