Abstract
A pattern is impressed on flocked fabric by applying a patterned cylinder to the flocked surface before the adhesive that retains the flocking has cured. The projections on the cylinder surface tilt the flock fibers contacted by them to a new orientation, thereby forming the pattern in the flocked surface. Subsequent curing of the adhesive preserves the pattern.
Claims1
A method for preparing a flocked product having tilted fibers which form a pattern, said method comprising the steps of:
- A. preparing a cylinder with a resinous outer surface and forming projections and depressions by laser milling said surface;
- B. applying to a surface of a substrate a water based adhesive;
- C. applying flocking fibers to said adhesive with a substantially uniform first orientation of said fibers to form a flocked substrate;
- D. passing said flocked substrate through a nip between said cylinder and a backup cylinder, engaging fibers of said flocked substrate with the projections of said cylinder such that the cylinder having said projections does not contact the adhesive and tilting the fibers engaged by said projections to an orientation different from said first orientation to provide the flocked substrate with tilted fibers which form a pattern;
- and
- E. drying and setting said adhesive.
