Application of acid / zinc chloride solution and analysis lyocell a100 quantitative analysis in a hybrid fiber

The present invention relates to a quantitative mixed A100 lyocell fiber analysis, and the acid chloride using a mass ratio of (1 to 3) :( 6.5 to 7.5) in formic acid / zinc chloride solution and the viscosity of the lyocell A100 plastic fibers, modal fibers, bamboo fibers mixed in the lyocell fibers A100 quantitatively analyzed. The method of the present invention is achieved by a standard curve final quantitative determination, detection can be realized when the content of the lyocell theoretical A100 5%, can be implemented strong; and regenerated fiber blended product qualification is important.
