Flocked transfer and article of manufacturing including the flocked transfer
View Patent ↗A flocked transfer is produced by applying a release agent to a release sheet and then applying the flocking to the release agent. Unlike the traditional method, a binder and hot melt film is not applied to the back of the flock. The transfer (which is essentially a flocked release sheet) is then applied to a substrate (i.e., an item of clothing, a rubber pad, etc.) by positioning a sheet of thermosetting hot melt film on the substrate; placing the transfer on the hot melt film with the flock in contact with the hot melt film; and applying heat and pressure. The heat melts the thermosetting hot melt film to bind the flock to the substrate and binds the flocking together. This method reduces the costs involved in producing flocked articles, especially for articles produced on a continuous basis.
1. A flocked assembly, comprising:
flock, said flock comprised of first ends and opposing second ends;
a pre-formed, solid, and self-supporting thermosetting film, wherein substantially all opposing second ends are in contact with and adhered to the thermosetting film; and
wherein the thermosetting film is:
free of a binder adhesive positioned between the thermosetting film and flock;
of substantially uniform thickness;
substantially flat upper and lower surfaces; and
is not adhered to a substrate.
2. A transfer comprising the flocked assembly of claim 1 .
3. The flocked assembly of claim 2 , wherein said first ends of said flock are adhered to a release sheet by a release agent and wherein the thermosetting film contacts said opposing second ends of the flock.

7. The flocked assembly of claim 1 , wherein the thermosetting film is precut to correspond to a shape of the transfer and wherein the thermosetting film is a thermosetting polyurethane.
8. The flocked assembly of claim 3 , wherein the release agent and release sheet are located on a first surface of the flock and the thermosetting film is positioned on a second surface of the flock and the first and second surfaces are in an opposing relationship.
9. The flocked assembly of claim 1 , wherein there is no hot melt thermoplastic adhesive located between the thermosetting film and the flock.
10. The flocked assembly of claim 1 , wherein the thermosetting film is not fully crosslinked.
11. The flocked assembly of claim 1 , wherein the flock is in direct physical contact with the thermosetting film.
12. The flocked assembly of claim 1 , wherein the thermosetting film is not fully activated.
13. The flocked assembly of claim 1 , wherein the thermosetting film is continuous.
14. A flocked assembly, comprising:
flock; and
a solid, self-supporting thermosetting film, wherein the flock is in contact with and adhered to the thermosetting film, wherein there is no intermediate adhesive positioned between the thermosetting film and flock and wherein the thermosetting film is not adhered to a substrate.
15. The flocked assembly of claim 14 , wherein said flock comprised of first ends and opposing second ends, wherein the thermosetting film is pre-formed and self-supporting, wherein substantially all second ends of the flock physically contact the thermosetting film, and wherein the thermosetting film has a substantially uniform thickness and substantially flat upper and lower surfaces.
16. The flocked assembly of claim 14 , further comprising:
a release sheet; and
a release agent in contact with the release sheet, wherein first ends of said flock are adhered to the release sheet by the release agent and wherein the thermosetting film contacts opposing second ends of the flock.
17. The flocked assembly of claim 16 , wherein said second ends of flock are not in contact with a hot melt binder adhesive.
18. The flocked assembly of claim 17 , wherein the thermosetting film comprises a thermosetting polyester and wherein the thermosetting film is not in contact with an acrylic or a hot melt thermoplastic adhesive.
19. The flocked assembly of claim 18 , wherein the thermosetting film is a thermosetting polyurethane film or a thermosetting polyester film.
20. The flocked assembly of claim 14 , wherein the flocked assembly is a transfer, wherein the thermosetting film is precut to correspond to a shape of the transfer, and wherein the thermosetting film is a thermosetting polyurethane.
21. The flocked assembly of claim 14 , wherein the thermosetting film is not fully crosslinked.
22. The flocked assembly of claim 14 , wherein there is no acrylic or hot melt thermoplastic binder adhesive located between the thermosetting film and the flock.
23. The flocked assembly of claim 14 , wherein the flock is in direct physical contact with the thermosetting film.
24. The flocked assembly of claim 14 , wherein the thermosetting film is not fully activated.
25. The flocked assembly of claim 14 , wherein the flock is embedded in the thermosetting film.
26. A flocked assembly, having:
flock; and
a self-supporting thermosetting film that is not adhered to a substrate and acts as the adhesive for the flock, wherein there is no binder adhesive located intermediate to said thermosetting film and said flock.
27. The flocked assembly of claim 26 , wherein said flock is comprised of first ends and opposing second ends, wherein the thermosetting film is a pre-formed solid, wherein substantially all second ends of the flock contact the thermosetting film, and wherein the thermosetting film has a substantially uniform thickness and substantially flat upper and lower surfaces.
28. The flocked assembly of claim 26 , further having:
a release sheet;
a release agent in contact with the release sheet, wherein first ends of said flock are adhered to the release sheet by the release agent; and
wherein the thermosetting film:
contacts opposing second ends of the flock,
comprises a thermosetting polyester, and
is not in contact with an acrylic or a hot melt thermoplastic adhesive.
29. The flocked assembly of claim 26 , wherein the thermosetting film is a thermosetting polyurethane film or a thermosetting polyester film.
30. The flocked assembly of claim 26 , wherein the flocked assembly is a transfer, wherein the thermosetting film is precut to a shape of the transfer, and wherein the thermosetting film is a thermosetting polyurethane.
31. The flocked assembly of claim 26 , wherein the thermosetting film is not fully crosslinked.
32. The flocked assembly of claim 26 , wherein there is no acrylic or hot melt thermoplastic binder adhesive located between the thermosetting film and the flock.
