Fixation Steamer and Ager for Printed Fabrics
topic
Print fixation steamers pass printed fabric through atmospheres of saturated or superheated steam at 100 to 175 degrees Celsius for 8 to 20 minutes to achieve reactive dye fixation on cotton, acid dye fixation on wool and silk, and disperse dye diffusion into polyester, with temperature and humidity control in the steamer being critical for consistent fixation that determines colour depth reproducibility and washing fastness of the printed fabric.
Role
Achieves the chemical fixation reaction that permanently bonds print dyes to textile fibres through controlled steam atmosphere conditions that activate the dye-fibre chemical reaction, with steamer temperature and humidity uniformity across the full print width and length being essential for consistent colour depth and fastness development across the full printed fabric area.
