Claims
- 1. A process for forming a strippable glass fiber wall covering comprising:
(a) providing a glass fiber fabric, (b) forming a first dried coating on both sides of said glass fiber fabric that is applied from an aqueous dispersion comprising starch and a polymeric latex binder, and (c) subsequently forming a second dried coating on said first dried coating on one side only of said glass fiber fabric that is applied from an aqueous dispersion comprising paraffin and rheology modifier with said second dried coating being capable of aiding in the removal of the wall covering from the wall.
- 2. A process according to claim 1 wherein said glass fiber fabric is a woven fabric.
- 3. A process according to claim 1 wherein the glass fiber fabric is a nonwoven.
- 4. A process according to claim 1 wherein the glass fiber fabric is supplied in roll form.
- 5. A process according to claim 1 wherein said starch component of the first dried coating is potato starch.
- 6. A process according to claim 1 wherein said polymeric latex binder component of the first dried coating is an acrylic latex binder.
- 7. A process according to claim 1 wherein said aqueous dispersion of the first dried coating includes a cross-linking agent.
- 8. A process according to claim 7 wherein said cross-linking agent of the first dried coating is a zirconium cross-linker.
- 9. A process according to claim 1 wherein said aqueous dispersion of the first dried coating additionally includes pigment.
- 10. A process according to claim 9 wherein said pigment of the first dried coating is titanium dioxide.
- 11. A process according to claim 1 wherein the aqueous dispersions of said first and second dried coatings are applied on a continuous process.
- 12. The process of claim 1 wherein the drying of the glass fiber fabric in steps (b) and (c) is accomplished through the use of drying cylinders.
- 13. The process of claim 1 wherein the drying of the glass fiber fabric in steps (b) and (c) is accomplished in air driers.
- 14. The process of claim 1 wherein the application of said aqueous dispersions in steps (b) and (c) is accomplished through the use of a rotating screen applicator.
- 15. The process of claim 1 wherein the applying of said aqueous dispersions in steps (b) and (c) is accomplished through the use of transfer rollers.
- 16. A strippable glass fiber wall covering formed by the process of claim 1 which can be readily removed from the wall by force applied by hand.
- 17. A strippable glass fiber wall covering formed by a process of claim 1 comprising a glass fiber fabric impregnated and coated with a first dried coating and having applied thereon a second dried coating to one of the surfaces, whereby the second dried coating serves as a separation layer that facilitates the removal of said wall covering from a substrate.
