Knowledge Management and Technology Transfer of an Innovative Natural Indigo Dyeing Technique on Cotton Yarn for Community Enterprises

Abstract

This research aimed to manage knowledge and transfer an innovative natural indigo dyeing technology on cotton yarn for community enterprises. The study began with the selection of target community enterprises in Si Sa Ket Province, followed by comprehensive theoretical and practical training workshops covering the new natural indigo dyeing technique, fundamental knowledge of cotton fiber properties, cotton yarn preparation for dyeing, product design principles, prototype development, and cost management. A knowledge manual was also produced as a reference document. The innovative dyeing technique utilizes wet indigo paste, caustic soda flakes, and thiourea dioxide (indigo-activating powder) as primary components, enabling dyeing completion within approximately 20-30 minutes—a significant improvement over the traditional process requiring up to 15 days. The results showed that 9 community enterprises participated in the project with a total of 72 trainees. Post-training satisfaction surveys completed by 58 participants revealed an overall satisfaction level at the highest tier (mean = 4.29 out of 5.00). Satisfaction scores were particularly high for lecture and practical training techniques (mean = 4.54) and for knowledge application utility (mean = 4.20). Participants reported significant improvements in occupational performance and work efficiency. These findings demonstrate that integrating organizational knowledge management with modern indigo dyeing technology can effectively enhance the capacity of community enterprises.
