摘　　要：Based on the analysis of the structure and properties of gardenia, the gardenia was extracted in neutral bath. The mordant dyeing of cotton, including pre-mordant, one-bath and post-mordant were studied, and the dyeing properties such as dye K/S value and color fastness were investigated. According to the structure and property of mordants including alum, copper sulfate, iron sulfate and rare earth, the interaction mechanisms among gardenia, mordant and cotton fibers were analyzed and the processing factors affecting the mordant dyeing were discussed. As a result, gardenia showed favorable dyeing performance on cotton. The soaping color fastness and crocking fastness were improved by 0.5-1 grade after fixation process with the selected dye-fixing agent and optimized process conditions. The dyeing process and fixation process were optimized.Based on the analysis of the structure and properties of gardenia, the gardenia was extracted in neutral bath.
