摘　　要：用65%硫酸溶解天丝A和丝光棉混合物,测定其溶液的吸光度值,根据Lasbeli定理计算其混纺比,分析结果与实际配比的偏差范围为-2.74%—1.80%,误差全部在标准FZ/T01053-2007的允差范围内,说明采用该方法来进行定量测定是可行的。Tencel A and mercerized cotton were dissolved in 65% H2SO4 and the absorption spectra were measured.The blending ratio of tencel A/mercerized cotton was determined applying Lasbeli theorem.The results showed that the derivation between analysis values and actual ratio changed from-2.74% to 1.80%,all satisfy the demand of FZ/T 01053-2007.The method is accurate and applicable for the quantitative determination of the blending ratio of tencel A/mercerized cotton.
