Uncertainty Analysis of Fiber Content in Cotton and Viscose Blended Fabrics
This paper took the blended fabric of cotton and viscose chemical staple fiber as an example to analyze the fiber content.The samples were quantitatively analyzed and tested according to GB/T 2910.6-2009"Quantitative chemical analysis of textiles-part 6:viscose fibers,certain cupramine fibers,modal fibers or lyocell fibers mixed with cotton(formic acid/zinc chloride method)",and the uncertainty of the content of cotton and viscose chemical staple fibers was evaluated.By analyzing the source of the uncertainty,the components of the uncertainty and the synthetic standard uncertainty are obtained,and the extended uncertainty of the test is finally obtained,so that the test results are more complete and scientific.
