The adhesives are fed from the drum melter through a heated hose to the traversing adhesive distribution system inside the rotary screen, just behind the doctor blade.
The traversing adhesive dispenser distribute the adhesive automatically over the set working width. This method of adhesive supply is brand-new and helps to distribute the adhesive more even and precise. Meanwhile the working width can be set without any mechanical changes.
The adhesive is pressed by the doctor blade through the screen holes and transferred to the substrate.
Different dot pattern (mesh or irregularly) and different screen thicknesses allow different coating weight and adhesive coverages.
The coating weight and the coverage define the bonding strength, the softness of the fabric and the breathability.
The large and right selection of screens is essential to fulfil the requirements likewise.
The screen coating system is the most precise system to apply adhesive without
glue in between the coated dots and therefore the final product (active wear) has an excellent air permeability and a soft hand.
Due to the coating on the surface of the substrate, the adhesive has less tendency to
penetrate into the substrate which effects a high bonding strength with less adhesive use than other coating processes.
