用溶解-分光光度计法测定兔羊毛混纺比

Measuring Blending Ratio of Rabbit Hair and Wool Spinning with “Solution Spectrophotometer Testing Method”

兔羊毛混纺样品用5%NaOH 溶液溶解后在分光光度计上测吸光度。因兔、羊毛溶液的吸光度有一定差异,用定量分析法就可求得混纺比,本方法的平均误差小于1%。

In this paper,after solving them with NaOHof 5%,the blended samples rabbit hair and wool are used to measure their absorbency with a spectrophotometer.The absorbency of rabbit hair and wool in solution exhibit certain variation under the given condition.Definite analysing testing method is adopted to find their blending ratio.It has been shown through test that this method is simple and realiable,and the mean error is within 1%.
