Abstract：In order to obtain a convenient and efficient method for the inspection of cotton sugar, the chromatic meter in textile industry was used to establish chromatic grading testing method (CGTM) and chromatic quantitative testing method (CQTM) of cotton sugar, practical tests have proved that the two methods for cotton sugar were feasible. Based on CGTM, color grades (blue to orange) were digitized description with chromatic parameters (a*, b*, h*), which can replace standard color paper, similar to the quantitative method. The CQTM can be directly used to describe cotton sugar content with the chromatic parameters, such as L*,C*,b*,K/S and dE*, however the fluctuation in fitting data of chromatic parameters for the same batch cotton is larger, and the difference of fitting method for chromatic parameter is significant, which needs to be researched in-depth.
