Transferable flocked fiber design material and method of making same

Claim 1

A transferable flocked fiber design material comprising a release support base, said base being coated on one surface thereof with a release adhesive layer, fibers releasably flocked at one end thereof in the said release adhesive layer, a fiber transfer adhesive layer applied to the other end of selected ones of said fibers, said fiber transfer adhesive being formed of an acrylic resin adhesive comprising an acrylic resin, a viscosity-imparting agent, a softening agent, and a hot melt adhesive applied over the said fiber transfer adhesive layer, said release adhesive layer comprising about 25% of polyethylene glycol, about 25% of paraffin emulsion and about 50% of an acrylic copolymer resin adhesive, the latter component having a viscosity of 1500-2500 cps, a PH of 4-6, and including about 42% solid content dissolved in about 58% water, said about 42% solid content consisting of about 36% resin and plasticizer and about 6% emulsifier.

Claim 7

A method for preparing a transferable flocked fiber design material comprising the steps of: applying a release adhesive layer to one surface of a release support base; partially heat treating so as to cause the said adhesive layer to partially penetrate into the said support base; the said release adhesive layer being formed of about 25% of polyethylene glycol, about 25% of paraffin emulsion and about 50% of an acrylic copolymer resin adhesive, the latter component having a viscosity of 1500-2500 cps, a PH of 4-6, and including about 42% of solid content dissolved in about 58% water, said about 42% solid content consisting of about 36% resin and plasticizer and about 6% emulsifier; releasably flocking fibers at one end thereof by electrostatic blasting on the said release adhesive layer to form an assembly; partially heat treating said assembly to result in releasable adhesion of said fibers to the said release adhesive layer; applying a fiber transfer adhesive layer to the other end of said fibers, said fiber transfer adhesive layer being an acrylic resin adhesive; applying hot melt adhesive onto said fiber transfer adhesive layer; removing any excess of said hot melt adhesive; and heat treating the resulting assembly to secure the hot melt adhesive to said fiber transfer adhesive layer, thereby resulting in a transferable flocked fiber design assembly.

Claim 8

A method for preparing a transferable flocked fiber design material comprising the steps of: applying a release adhesive layer to one surface of a release support base; partially heat treating so as to cause the said adhesive layer to partially penetrate into the said support base; the said release adhesive layer being formed of about 25% of polyethylene glycol, about 25% of paraffin emulsion and about 50% of an acrylic copolymer resin adhesive, the latter component having a viscosity of 1500-2500 cps, a PH of 4-6, and including about 42% of solid content dissolved in about 58% water, said about 42% solid content consisting of about 36% resin and plasticizer and about 6% emulsifier; releasably flocking fibers at one end thereof by electrostatic blasting on the said release adhesive layer to form an assembly; partially heat treating said assembly to result in releasable adhesion of said fibers to the said release adhesive layer; applying a fiber transfer adhesive layer to the other end of said fibers, said fiber transfer adhesive layer being an acrylic resin adhesive; applying hot melt adhesive onto said fiber transfer adhesive layer; removing any excess of said hot melt adhesive; and heat treating the resulting assembly to secure the hot melt adhesive to said fiber transfer adhesive layer, thereby resulting in a transferable flocked fiber design assembly.
