A LAMINAR STRUCTURE FOR USE AS A SURFACE COVERING COMPRISING: A NON-WOVEN FABRIC SHEET OF CONTINUOUS FLIAMENTS WHEREIN SAID SHEET HAS A THICKNESS OF FROM 0.1 TO 0.4 MM AND A WEIGHT OF 0.5 TO 4 OUNCES PER SQUARE YARD, A PILE OF FLOCKED FIBERS SECURED TO ONE FACE OF SAID FABRIC SHEET BY AN ADHESIVE, A FOAMED SHEET OF POLYOLEFIN RESIN SELECTED FROM THE GROUP CONSISTING OF POLYETHYLENE AND POLYPROPYLENE RESINS BONDED TO THE FACE OF SAID FABRIC SHEET OPPOSITE TO THAT ON WHICH SAID FLOCKED FIBERS ARE SECURED.
Claim 3
Dependent Claim
90 words
A laminar structure for use as a surface covering comprising: a non-woven fabric sheet of continuous filaments wherein said sheet has a thickness of from 0.1 to 0.4 mm and a weight of 0.5 to 4 ounces per square yard, a pile of flocked fibers secured to one face of said fabric sheet by an adhesive, a foamed sheet of polyolefin resin selected from the group consisting of polyethylene and polypropylene resins bonded to the face of said fabric sheet opposite to that on which said flocked fibers are secured.
Claim 4
Dependent Claim
90 words
A laminar structure for use as a surface covering comprising: a non-woven fabric sheet of continuous filaments wherein said sheet has a thickness of from 0.1 to 0.4 mm and a weight of 0.5 to 4 ounces per square yard, a pile of flocked fibers secured to one face of said fabric sheet by an adhesive, a foamed sheet of polyolefin resin selected from the group consisting of polyethylene and polypropylene resins bonded to the face of said fabric sheet opposite to that on which said flocked fibers are secured.
Claim 5
Dependent Claim
36 words
