    Abstract  Application effect of digital color spinning measuring and matching system was discussed.Color measurement and color matching，formula modification，colored yarn simulation，quality prediction，raw material management and other functions of the intelligent digital color spinning rapid color measuring and prediction system were introduced.Four kinds of polyester and viscose colored yarns were taken as examples，color matching effect and economic benefits of the system were analyzed.The results showed that compared with manual color matching，sampling times of color measuring and matching system was reduced to 2 times to 3 times，design time of formula was also reduced to 1/5 of the manual color matching.The system-designated formula included functional design formula containing specific raw materials，which made cost of yarn raw materials reduced.Theoretical color difference between system formula sampling and the standard sampling was not larger than 0.5.It is considered that there is no obvious visual difference between yarn sampling color of system color matching and the standard sample.
