Abstract

Abstract A transferable flocked fiber design or sticker material which comprises a releasably flocked fiber base including fibers releasably flocked at one end to one major surface of a release support base sheet in upright position by means of a release adhesive layer; and a thermoplastic and pressure-sensitive synthetic resin layer applied to the other end of the flocked fibers. The entire area of the fiber-flocked surface of the release support base sheet is colored or printed or a selected area of the surface is colored or printed in a desired design or pattern and hot melt resin in the form of particles or pellets is sprinkled over the colored or printed surface of the release support base sheet. A method for preparing the releasably flocked fiber base in which a release adhesive layer is formed on one major surface of a release support base sheet, fibers are releasably flocked to the adhesive-applied surface of the release support base sheet and the adhesive-applied surface is colored or printed.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 135 words
A method for preparing a releasably flocked fiber base for a transferable flocked fiber design or sticker material comprising the steps of: applying a release adhesive in a liquid state to one major surface of a release support base sheet to form a release adhesive layer, said release adhesive being capable of retaining a viscous state for a predetermined period of time even after the application and drying of the adhesive, drying said release adhesive with the application of heat to obtain a still viscous adhesive layer, and releasably flocking a plurality of fibers at one of the ends thereof to said still-viscous adhesive layer of the base sheet in substantially upright position by electrostatic flocking means so as to embed said ends of the fibers in said still-viscous adhesive layer in a shallow depth.
Claim 2
Independent Claim 135 words
A method for preparing a releasably flocked fiber base for a transferable flocked fiber design or sticker material comprising the steps of: applying a release adhesive in a liquid state to one major surface of a release support base sheet to form a release adhesive layer, said release adhesive being capable of retaining a viscous state for a predetermined period of time even after the application and drying of the adhesive, drying said release adhesive with the application of heat to obtain a still viscous adhesive layer, and releasably flocking a plurality of fibers at one of the ends thereof to said still-viscous adhesive layer of the base sheet in substantially upright position by electrostatic flocking means so as to embed said ends of the fibers in said still-viscous adhesive layer in a shallow depth.
Claim 3
Dependent Claim 17 words
The method as set forth in claim 1, wherein said release adhesive is an acrylic acid copolymer.
Claim 4
Dependent Claim 38 words
The method as set forth in claim 2, wherein said release adhesive has been dried for 0.5 to 1 minute at about 80° C. after application to the base sheet and prior to application of the flocked fibers.
