Non-contact spray technology achieves zero chemistry waste


Knitted fabric printing and dyeing company Sezginler Tekstil, Tekirgag/Turkey, recently installed 4 non-contact spray systems from the manufacturer of finishing systems Baldwin Technology Company Inc., St. Louis, MO/USA.

The TexCoat G4 spray systems were installed to its softening finishing processes and very even finishing quality, and considerably reduced chemistry and energy consumption can be reached. By integrating Baldwin Technology’s TexCoat G4 into this production step, finishing could now be accomplished wet-on-wet via pad/foulard followed by the non-contact spray system. In both wet-on-wet and wet-on-dry processes it delivers high uptime, consistent quality and practically zero chemistry waste. The system provides continuous and even application. Another downside to the pad/foulard method is that it frequently needs to be drained of as much as 50 l of chemistry, depending on the production. This equates to a considerable amount of chemistry and time going to waste at every drain, which is completely eliminated. With the new system, draining is no longer required. Sezginler Tekstil reported that its energy consumption for drying decreased by as much as 50% in the wet-on-dry application. The non-contact spray system allows for a higher concentration of chemistry mix with lower pick-up requirements. With less wet pick-up, the fabric can pass through the stenter faster and with lower heat, reducing the energy consumption. Also the option of applying chemistry to one side of the fabric is possible. This avoids unwanted pigmentation on the prints or when running fabric with one-sided finishing characteristics. Additionally, applying chemistry on just one side is significantly more cost-effective since the chemistry consumption will be 50% less compared to a dual-sided application.
