摘　　要：对聚酯纤维与聚乙烯纤维混纺产品的定量分析有FZ/T 01162—2022《聚乙烯纤维与某些其他纤维的混合物(石蜡油法)》,该方法使用石蜡油/三氯甲烷为溶解试剂,溶解温度需达400℃以上,试验条件要求较高。为了更好地对聚酯纤维与聚乙烯纤维进行定量分析,本文采用非标方法氢氧化钠法和标准方法进行正确度验证和重复性试验,以40%氢氧化钠溶液作为溶解试剂对聚酯纤维与聚乙烯纤维混纺产品进行定量分析,在90℃水浴中振荡溶解30 min,将聚酯纤维从已知干燥质量的混合物中溶解去除。结果表明,使用氢氧化钠法可以降低对环境的污染和身体健康的危害,且该方法操作简单,结果准确可靠,适用于聚酯纤维与聚乙烯纤维混纺产品的定量分析。The quantitative method standard for polyester fiber and polyethylene fiber blended products is FZ/T01162-2022,which uses paraffin oil/chloroform as the dissolving reagent,the dissolution temperature needs to be above 400℃,and the test requirements are high.The operation is relatively complicated,and there are high requirements for the experimental environment and waste liquid recovery.In order to better quantitatively analyze polyester fibers and polyethylene fibers,this article uses non-standard methods such as sodium hydroxide method and standard method for accuracy verification and repeatability testing.This study used a 40%sodium hydroxide solution as a dissolution reagent for quantitative analysis of polyester fiber and polyethylene fiber blended products.The polyester fibers were dissolved and removed from the mixture with known dry mass by shaking in a 90℃ water bath for 30 minutes.The experimental results show that the use of sodium hydroxide method can reduce environmental pollution and harm to human health,and this method is easy to operate,with accurate and reliable experimental results,suitable for quantitative analysis of polyester fiber and polyethylene fiber blended products.
