Abstract
A wall covering includes a composite structure that includes a first layer forming a non-image side of the composite structure and a second layer laminated to the first layer forming an image side of the composite structure. The first layer includes a fabric to facilitate air flow on the non-image side. The image side has a surface roughness of less than or equal to 5 microns by PPS method. The second layer includes one of synthetic polymeric fiber in a non-woven structure and a synthetic polymeric film. The wall covering is a Type-II wall covering that is PVC-free.
Claims15
A wall covering comprising:
- a composite structure having an image side and a non-image side, the composite structure comprising:
- a first layer having a fabric structure with warp and weft to facilitate airflow on the non-image side;
- and
- a second layer laminated to the first layer, the second layer comprising one of synthetic polymeric fiber in a non-woven structure and a synthetic polymeric film, the second layer having a surface roughness of less than about 5 microns by PPS method on the image side;
- an image receiving layer coated on the second layer to support an ink image;
- and
- an anti-mechanical wear layer coated on the image receiving layer, the wall covering being PVC-free and having a durability of Type-II wall coverings.
A composite structure to support a wall covering comprising:
- a first layer fabric forming a non-image side of the composite structure, the first layer fabric comprising one or both of natural fibers and synthetic fibers in a fabric structure that is one of woven, non-woven, knitted and tufted to facilitate air flow on the non-image side;
- and
- a second layer laminated to the first layer to form an image side of the composite structure, the second layer comprising a synthetic polymeric component in one of a non-woven fiber structure and a film and having a surface roughness of less than or equal to 5 microns by PPS method,
- wherein the composite structure is PVC-free and has a mechanical breaking strength greater than 50 lb of Type-II wall covering standards.
A PVC-free Type-II wall covering comprising:
- a composite structure comprising:
- a first layer fabric comprising natural fibers and synthetic fibers in a woven structure with warp and weft to facilitate airflow on a non-image side;
- and
- a second layer laminated to the first layer fabric and having a surface roughness of less than about 5 microns by PPS method on an image side, the second layer comprising one of a non-woven fiber structure that comprises synthetic polymeric fiber within a range of about 10% to about 40% by weight of total fiber and a synthetic polymeric film having a thickness within a range of about 40 microns to about 300 microns;
- an image receiving layer coated on the image side of the second layer to support an ink image;
- and
- an anti-mechanical wear layer coated on the image receiving layer having a transformable porous structure.
