本文件规定了在对cupro和lyocell混合物重新染色后，使用ISO 20705中所述的显微镜分析对cupro和lyocell混合物进行定量分析。 本试验方法仅适用于cupro和lyocell或这些混合物。如果存在其他纤维，则使用ISO/TR 11827的试验方法对其进行识别，并使用ISO 1833系列的相关部分将其移除。 此方法不适用于纤维表面在加工过程中受损（例如化学或物理）。

This document specifies the quantitative analysis of cupro and lyocell mixtures using the microscopical analysis as described in ISO 20705 after re-dyeing cupro and lyocell mixtures. This testing method is applied only for cupro and lyocell, or those blends. If other fibres are present, those are identified using the test method of ISO/TR 11827 and removed using the relevant parts of the ISO 1833 series. This method is not applicable for the fibre surface is damaged during the process (e.g. chemically or physically).
