羊毛 酸含量的测定

[中文适用范围]： 该方法适用于任何形式的未染色羊毛，例如散纤维、棉条、纱线或织物。 当测试过程中提取的染料量不干扰滴定终点的测定时，它也适用于染色的羊毛。 测定值以质量百分比表示。 [外文原描述]： The method is applicable to undyed wool in any form, for example loose fibre, sliver, yarn or fabric. It is also applicable to dyed wool when the amount of dye extracted during the test does not interfere with the determination of the end-point of the titration. The determined value is expressed as a percentage by mass.
