摘　　要：本研究采用次氯酸钠溶液作为溶解试剂对动物毛纤维、桑蚕丝与亚麻、苎麻、大麻混纺产品进行定量分析,在20℃水浴中振荡溶解40 min,将某些蛋白质纤维从已知干燥质量的混合物中溶解去除将残留物清洗、烘干和称重,从而计算出各组分纤维的质量百分含量。在此条件下,探讨不溶纤维亚麻、苎麻、大麻的质量修正系数(d值),并使用该方法对已知配比的混合物样品进行验证。结果表明,该方法的具有良好的重复性,精密度满足纤维定量检测的要求,可用于某些蛋白质纤维与亚麻、苎麻、大麻混合物的定量分析。This article uses sodium hypochlorite solution as a dissolution reagent to quantitatively analyze animal hair fibers,mulberry silk and blended products of flax,ramie,and hemp.After shaking and dissolving in a 20℃water bath for 40 minutes,certain protein fibers are dissolved and removed from the mixture with known dry mass.The residue is then washed,dried,and weighed to calculate the mass percentage content of each component fiber.Under these conditions,the quality correction coefficient d values of insoluble fibers such as flax,ramie,and hemp were explored,and this method was used to verify the mixture samples with known ratios.The experimental results showed good repeatability and precision,meeting the requirements of fiber quantitative detection.The results indicate that the method is simple to operate,accurate and reliable in experimental results,and suitable for quantitative analysis of mixtures of flax,ramie,hemp,and certain protein fibers.
