GB/T 25813-2010 "Standard Bleached Cotton Yarn for Dye Testing" specifies the technical requirements and related specifications for standard bleached cotton yarn used in dye testing, applicable for unifying the benchmark of dye testing. The standard requires a cotton fiber content of ≥95%, a whiteness of ≥85 degrees, and a residual bleaching agent content of ≤0.02%. Testing requires instruments such as a whiteness meter and a fiber content analyzer. This standard addresses the issue of data deviation caused by inconsistent specifications of cotton yarn used in testing, ensuring the accuracy and comparability of test results.
