Abstract
A method for dying and/or printing adhesive closure parts (10) having a plurality of hooks (12) predominately made of a plastic material connected to a carrier (14), applies a dye medium to the surface (16) of the adhesive closure part (10) or its parts by an application unit (18). Because the dye used is based on a solvent free wax applied by the application unit (18) in a melted form in droplets, bubbles, or pellet form, and enters into a fixed connection to the surface (16) in the cooled, cured state, a wax dye application may be achieved that is markedly colorfast and UV resistant.
Claims10
A method of at least one of dyeing and printing an adhesive closure part, comprising the steps of:
- applying a molten dye medium to a surface of a plastic adhesive closure part having a plurality of interconnecting parts connected to a backing, the dye medium having a solvent-free wax applied in at least one of droplet form, bubble form and pellet form by an applicator;
- prior to applying the dye medium to the surface of the adhesive closure part, at least one of functionalizing and coating the surface with an active coating for better adherence of the dye medium;
- and
- cooling and solidifying the dye medium to bond the dye medium tightly to the surface, and aftertreating the solvent-free wax applied to the surface by applying at least one of actinic energy, UV light and IR light applied to the solvent-free wax.
