Either flat screen printing or rotary screen printing would generate plentiful of waste water, consume too much energy and have high defective products rate. Traditional transfer printing has limited applying arena only to hydrophobic fabrics. Digital printing is an ideal solution but could only be applied in small quantity productions currently. A new waterless printing technology was recently developed by a dyeing & finishing technology research company located in Keqiao economic development zone. The waterless printing technology is introduced to have synthesized the advantages of traditional flat screen printing, rotary screen printing, transfer printing and digital printing technology. Sublimation problem of natural fiber printing using disperse dyes under high temperature is successfully overcome and that the rinsing process can also be saved by using this waterless printing technology.

One production line could save up to more than 2oo tons of waste water every day directly cutting down 45% of waste water discharge by using this technology which would only took 400 to 500 thousand RMB upgrading fees on the original printing machines. The printing result is also very delicate that could even eclipse the fine effect of yarn-dyed fabrics. Also by using their latest modifying agent, double-face-printing at a single time could be realized while printing curtains.

Aside from perfect printing effects, this latest waterless printing technology also possesses other environmentally friendly advantages: zero waste water discharge, no steaming treatment needed, no rinsing process needed which unarguably could save lots of cost for companies. In the era of green production, this major printing breakthrough undoubtedly saw huge market potential ahead.
