Technological development trends Environmental Protection and Sustainable Development Environmental regulations in various countries, such as EU REACH and China's "dual carbon" policy, are forcing the industry to transform, replacing traditional solvent based materials with water-based inks, plant dyes, biodegradable printing adhesives, and other alternatives. The circular economy promotes the application of "waterless printing" technology (such as digital direct printing) to reduce wastewater discharge. Innovation in Digital Printing Technology The popularization of high-speed inkjet printing equipment reduces the cost of small batch customization and meets the personalized needs of Generation Z; It is expected that by 2030, digital printing will account for over 30% of the global textile printing market. The research and development of functional materials such as antibacterial, UV resistant, and temperature sensitive color changing intelligent printing materials have great potential for application in fields such as medical and outdoor equipment.
