Flocking refers to the process of depositing short monofilament textile fibers on a substrate previously coated with glue. The surface thus acquires a high-quality velvet or velour effect. Flocking is typically performed in an electrostatic field which accelerates and aligns the fibers so that they remain vertical in the glue bed. The bonding of the glue bed on the fabric substrate is an important factor in the quality of the flocking.
Fabric pretreatment with Openair® plasma substantially increases the bonding capability of the modified surface and is therefore a highly effective processing factor in textile finishing.
Openair® plasma has proven its value in the automobile industry as well, where it has been used as a pretreatment in flocking processes for years (such as flocking on EPDM, glove compartments or fabric itself).
