The patent-pending FlexDyer process is imogo’s most flexible solution for sustainable dyeing of textiles. As digital textile printing gains ground because of the sustainability constraints of traditional dyeing processes, the industry is coming up with innovative solutions for textile dyeing concepts based on using nozzles and spray units similar to inkjets. One of the recognized innovators in this field is Sweden based imogo.
The combination of high-speed spray application with the unique imogo autoclave fixation step enables high output at considerably reduced costs. The FlexDyer process is flexible, not least because of the range of fiber types and mixes that can be treated. Most types of traditional dye classes can be used. FlexDyer can help in reducing the number of dyeing processes used today.
The process contains a Dye-Max application unit, a closed chamber where high-performance spray valves apply the dye dispersion. The spray cassettes consist of precision nozzles for accurate and consistent coverage combined with the patented imogo pro speed valve that controls the volume applied. The chamber is equipped with an exhaust system and droplet separator to ensure that the unit’s environment is free from sprayed particles.
The spray cassettes play a crucial part in the FlexDye line. The pre-moistening station features similar spray cassettes. These are easily exchanged without the need for tools in less than a minute. The efficient dye feed line and nozzle cleaning function enables quick changeovers also between different colors. After applying the dye dispersion, the fabric is rolled onto a shaft. The roll is moved to the fixation autoclave.
In combination with the Mini-Max spray test unit, dye tests are done of-line. After being tested and verified without interrupting the production equipment, recipes are defined and loaded into the Dye-Max HMI. The Dye-Max will reproduce the Mini-Max results.
The manufacturer claims that the FlexDyer is suitable for short sample runs with multiple changeovers and long-volume runs. The autoclave can be configured for either requirement. Change from one to the other is a simple maneuver.
