FZ/T 50064-2024The color difference test method for chemical fiber short fibers will be used2025-07-01Formally implemented.

This document describes the test method for determining chromatic aberration of short fiber products using a spectrophotometer. This document applies to chemical fiber short fibers. Shanghai Yunding Company participated in the drafting of standards.

For fiber products, the geometric measurement conditions are as follows:d/8The integrating sphere colorimeter is used, and the testing conditions are as follows:D65Light source,CIE1964Standard chromaticity observer, measuring aperture20 mm～30 mmIf other measuring apertures are used, they should be noted in the report. Non fluorescent sample testing, including specular reflection measurement, fluorescent sample testing, using non specular reflection mode measurement. Shanghai Yunding provides you with detailed execution methods and recommended instruments.
