Paddyeing
Pad-dyeing, often written paddyeing in some texts, is a continuous dyeing process used in textile finishing to color fabric. It relies on a padded application in which fabric is passed through a dye liquor and then squeezed by rollers to control liquor uptake. The fabric is subsequently dried and heat-fixed to set the color.
Process and sequence: The fabric enters a padder where dye liquor containing fixing auxiliaries is pressed
Equipment and configurations: Pad-dyeing systems include open-width and tubular padder lines, followed by drying and fixation
Dyes and fabrics: Pad-dyeing is commonly used for cellulose fibers (e.g., cotton, viscose) and their blends, employing
Advantages and limitations: Advantages include good color uniformity, controllable shade depth, and suitability for continuous production
