GB/T 33729-2017 "Textiles—Tests for colour fastness—Cotton rubbing cloth" is a supporting standard for textile colour fastness to rubbing tests (such as GB/T 3920). It specifically defines the technical requirements for the standard cotton rubbing cloth used in the tests, including its fiber composition, yarn specifications, fabric structure, mass per unit area, whiteness, and pH value of the untreated surface. Ensuring consistent performance of the rubbing cloth is a prerequisite for obtaining comparable test results.
