GB 1760-1979 "Method for determination of tensile strength increase after painting of cloth" is a national standard, which stipulates the measurement method of tensile strength increase after painting of cloth. The content covers the test principle, equipment requirements, sample preparation (treatment of cloth before and after painting), tensile test operation steps and data calculation methods, by comparing the tensile strength value of cloth before and after painting, calculate the strength increase rate. The standard is applicable to the performance testing of various types of cloth after painting, providing a technical basis for evaluating the impact of painting process on the mechanical properties of cloth, and helping to standardize the mass inspection process of painted cloth.
