On February 24, AIIFA attended the World Trade Fair held by China DPES and took the opportunity to see a lot of textile printing machines. For example, textile direct printing machines, digital printing machines and other large textile printing machines. The take-up system and the paper feeding system of such large printing machines are controlled by tension sensing, which coincides with AIIFAR's DTF printers. By talking with other DTF printer manufacturers, it seems that they are not considering adding a tension take-up system and a tension feeding system. By conducting market research on DTF printers through this expo, we found that machines with an integrated purifier would have more selling advantages, which is one of the advantages that AIIFAR's DTF printers have been able to sell worldwide and continue to receive recognition and praise from buyers worldwide.
