Natural ingredients used as fabric dyes is expected to reduce environmental pollution due to the use of synthetic dyes. Chinese petai leaves contain flavonoids which produce a yellowish green color. This study was conducted to determine and analyze the color quality natural dyes of Chinese petai leaves on primissima mori fabric. This study used descriptive qualitative data methods. The use of water and NaOH-water was used in this study as a variation of solvent. Dyeing was done by soaking the fabric in 15 minutes to 30 minutes, then drying and repeating until 15 times. The dyeing result was tested in term of color difference and type. Based on the research, it can be concluded that Chinese petai leaves extract with NaOH – water solvents achreved value of 85.69% while extract with water solvent achieved value of 72.63%.
