摘　　要：开发出了准确度及精密度均较高的聚乳酸纤维与羊毛、棉、尼龙混纺产品定量分析的实验方法。实验表明:对于不同比例的聚乳酸混纺产品,实测结果与理论比例的绝对误差小于±1%;在95%的置信度下,对同一混纺比例的聚乳酸混纺产品,连续测10次所得结果的置信界限小于±1%。The high accuracy and the precision of the quantitative analysis method is developed. The experiments indicates that, using the method to analyze PLA products with different blend ratios, the absolute error between measured value and theoretical value is less than 1%, and when the confidence level is 95 %, the confidence limits of measured results of 10 times are all less than 1% for the same blend ratio of PLA products.
