This research aims to experiment with natural dye from the longan leaves, Color fastness, UV protection, Designed textile products from Textile dyeing of longan leaves. and to teach the dye from longan leaves for design and processing of textile products to the community under the concept of the creative economy. The study consisted of two parts, The first part is Color fastness and UV protection from fabric dye from longan leaves. The second part is Designed textile products from Textile dyeing of longan leaves. The research area at Yu Wa San, Pa Tong district, Chiang Mai province area planted with longan. This research is part of the solution to the problem of waste longan leaves. In addition, farmers have to produce compost leaves and fruits are often destroyed by the fire. Impact on air pollution and Haze occurred in Chiang Mai now. Natural dye extracted from longan leaves was applied to a silk fabric by exhaustion dyeing process. Aluminium potassium sulfate, ferrous sulfate, copper sulfate, and stannous chloride were used as mordants. The dyeing was conducted with and without metallic salt mordants, using three different mordanting methods, pre-mordanting, meta-mordanting, and post-mordanting. The colour of each dyed material was investigated in term of the CIELAB (L*, a* and b*) and K/S value. The color fastness to washing, rubbing, perspiration, light, and water of the dyed samples was determined according to ISO test method. The results show that the optimal results were achieved when dyeing at 80 ?C for 50 minutes and at pH 3. Silk fabric dyed in a solution composed of a Longan from leaves without mordant showed a shade of pale yellowish-brown, while those mordanted with stannous chloride, alum, and copper sulfate produced a variety of medium to dark yellowish-brown color shades. However, duller and darker brown shade was obtained with ferrous sulfate mordant. The color fastness to washing, water, perspiration and rubbing were good to very good. However, the light fastness results showed fair level, except fabric without mordanted, whose colour change rating was poor. The results confirmed that natural dyes from longan leaves extract with metal mordants have potential applications in fabric dyeing and in producing very good UV-protective silk fabrics. The second part is research data collected from literature research related research and field data was collected by interviewing, recording a career field research, brainstorming sessions and participatory action research between the villagers to researchers. The findings presented by descriptive analysis. The result is Textile product design of longan leaves dyed fabrics must take into account the capacity of the group. The villagers have restrictions on the production of textile products. There is no potential for forming other products. In addition to the garment as well as the group was started. The natural dyes of the longan leaves is new knowledge for the group. Therefore, textile products in the early to conclude that the textile products the group members have expertise in manufacturing men's casual shirts ladies casual shirts and scarf. Create patterns with a variety of tie-dye technique. The silk material used as the main material used is cotton minority. Users is a group of conservative tastes, nature lovers and those with artistic taste. The procession design and production-oriented textile products are Green Design
