Acid Ink Application in Printing
The digital transfer printing technology and equipment is now available everywhere, and the market for nylon fabric printing mainly uses screen printing, cold transfer printing, digital direct spray printing and several other methods. Flat or circular screen printing is difficult for complex and delicate colour patterns, and there is a lot of effluent in the printing process. Cold transfer printing, which involves wetting the fabric and transferring it at room temperature, is sensitive to the degree of wetness of the fabric during the transfer process and once the degree of wetness changes during the transfer process, the colour difference is often intolerable. Digital direct-jet printing is the direction in which industry colleagues are working. This is done by ink-jet printing acidic inks on sized fabrics, followed by steam evaporation and washing and drying.
