Article: Quantitative fiber mixture analysis by scanning electron microscopy1: Part VI: Possibilities and limitations of the analysis of binary specialty fiber/wool blends in view of test method IWTO-58

ABSTRACT

Test Method 58 was established by the International Wool Textile Organization in 2000 to analyze textile products made from specialty fibers, sheep's wool, and their blends using the scanning electron microscope. This part of the series critically examines the design of the analytical approach for quantitative analysis of binary blends specified in IWTO-58. The 95% confidence range is established as a suitable measure for the precision and accuracy of the method. The most critical, legal, and technical issue of quantitative analyses of binary wool/specialty fiber blends is the requirement of 3 weight-% accuracy. This accuracy is not consistently reached with the current analytical ...
