摘要
分别使用0.5mol/L次氯酸钠法、75%硫酸法、甲酸/氯化锌法对11种配比的毛粘试样和普通样品进行试验,分析在一定范围内可优先选择的试验方法。结果如下:羊毛含量>25%时,建议采用0.5mol/L次氯酸钠方法;羊毛含量<25%时,建议优先采用甲酸/氯化锌的方法。75%硫酸法适用范围较小,适用于毛含量<25%的浅色样品。
In order to Search a preferred way for detecting different ratio of wool/rayon blends samples and Common samples by using 0.5mol/L sodium hypochlorite method, 75% sulfuric acid method and acid/chloride zinc method .The results are as follows： when Wool content 〉 25%, 0.5 mol/L sodium hypoehlorite method is recommended; when Wool content 〈 25%, it is preferred by acid/chloride zinc method ;75% sulfuric acid method applicable scope is smaller, just suitable for wool content 〈 25% of the light color samples.
