皮革 - 色牢度试验 - 耐磨损色牢度
This document ISO 20433:2024 specifies a method to determine the amount of colour transferred from the surface ofcoloured leather to other surfaces by rubbing.
Two tests are carried out,one with a dry rubbing cloth and one with a wet rubbing cloth.
The method is applicable to all types of coloured leather. Since after-treatments of the leather as well assurface finishes can affect the degree of colour transfer,the test can be made before and/or after suchtreatments.
本文件规定了一种测定通过摩擦从有色皮革表面转移到其他表面的颜色量的方法。
进行了两种测试，一种是用干摩擦布进行的，另一种是用湿摩擦布进行的。
该方法适用于各种类型的彩色皮革。由于皮革的后处理以及表面处理会影响颜色转移的程度，因此测试可以在此类处理之前和/或之后进行。
