This is currently a barrier to the popularization of cotton T-shirt direct printing. In order to solve these bottlenecks, many scientists in the world have joined the research and development ranks of cotton T-shirt direct-injection machine technology. At present, many key problems have been gradually broken through. The advantages of Yanyan cotton T-shirt direct-injection machine: First, highly automated, ergonomic optimization is very reasonable; second, the special environmentally friendly paint ink, the color is true and durable, and does not fade; third, the machine and software operations are very good Simple, fool-like control panel and operation interface; fourth, small footprint and low labor cost.
