Abstract

A golf practice mat comprising a backing defining an upper surface and a lower surface, a first plurality of elongated polyethylene fibers stitched onto the backing so as to project upwardly from the upper surface thereof, a second plurality of durable nylon fibers stitched onto the backing adjacent to and curled about the first plurality of fibers, the first and second pluralities of fibers being adhesively bonded to the backing and a shock absorbing pad bonded to the lower surface of the backing.

Claims

exact text as granted — not AI-modified
1 . A golf practice mat comprising a backing defining an upper surface and a lower surface, a first plurality of elongated polyethylene fibers stitched onto said backing so as to project upwardly from said upper surface thereof, a second plurality of durable nylon fibers stitched onto said backing adjacent to and curled about said first plurality of fibers, said first and second pluralities of fibers being adhesively bonded to said backing and a shock absorbing pad bonded to said lower surface of said backing. 
   
   
       2 . The golf practice mat of  claim 1  wherein said polyethylene fibers have a coefficient of friction within the range of 0.125-0.200 and a tensile strength having a break point in excess of 1.5 megapascals. 
   
   
       3 . The golf practice mat of  claim 1  wherein said first and second plurality of fibers define a turf having a density within the range of 1600-3300 ounces per cubic yard. 
   
   
       4 . The golf practice mat of  claim 2  wherein said nylon fibers have a fineness within the range of 3570-4830 denier. 
   
   
       5 . The golf practice mat of  claim 2  wherein said polyethylene fibers have a fineness within the range of 8500-11,500 denier. 
   
   
       6 . The golf practice mat of  claim 5  wherein said nylon fibers have a fineness within the range of 3570-4830 denier. 
   
   
       7 . The golf practice mat of  claim 2  wherein said backing is comprised of an open weave material having a pick count within the range of 11-22. 
   
   
       8 . The golf practice mat of  claim 2  wherein said first and second plurality of fibers define a turf having a density within the range of 1600-3300 ounces per cubic yard. 
   
   
       9 . The golf practice mat of  claim 2  wherein said first and second plurality of fibers comprise a turf, said turf having a gauge within the range of about 0.375-0.500 in. and wherein said first plurality of fibers define a pile height of about 0.750 in. 
   
   
       10 . The golf practice mat of  claim 2  wherein said first and second pluralities of fibers are adhesively bonded to said backing by a single component heat cured urethane adhesive comprised of polyols and isocyanates. 
   
   
       11 . The golf practice mat of  claim 4  wherein said first and second plurality of fibers define a turf having a density within the range of 1600-3300 ounces per cubic yard. 
   
   
       12 . The golf practice mat of  claim 4  wherein said backing is comprised of an open weave material having a pick count within the range of 11-22. 
   
   
       13 . The golf practice mat of  claim 1  wherein said backing is comprised of an upper backing layer and a lower backing layer, said lower backing layer being adhesively bonded to said upper layer and formed of an open weave woven material and wherein said upper layer is comprised of a non-woven material having a density greater than the density of said lower backing layer. 
   
   
       14 . The golf practice mat of  claim 2  wherein said backing is comprised of an upper backing layer and a lower backing layer, said lower backing layer being adhesively bonded to said upper layer and formed of an open weave woven material and wherein said upper layer is comprised of a non-woven material having a density greater than the density of said lower backing layer. 
   
   
       15 . The golf practice mat of  claim 13  wherein said open weave material comprises polypropylene and said non-woven material comprises a thermally-bonded spun laid non-woven material. 
   
   
       16 . The golf practice mat of  claim 2  wherein said pad is comprised of chemically cross-linked closed cell polypropylene foam. 
   
   
       17 . A golf practice mat comprising a backing defining an upper surface and a lower surface, a first plurality of elongated fibers stitched onto said backing so as to project upwardly from said upper surface thereof, a second plurality of fibers stitched onto said backing adjacent to and curled about said first plurality of fibers, said first and second plurality of fibers being adhesively bonded to said backing and a shock absorbing pad bonded to said lower surface of said backing and wherein said first plurality of fibers define a coefficient of friction within the range of 0.125-0.200 and a tensile strength having a breaking point in excess of 1.5 megapascals and wherein said second plurality of fibers are comprised of a nylon material having a fineness within the range of 3570-4830 denier. 
   
   
       18 . The golf practice mat of  claim 17  wherein said pad is comprised of chemically cross-linked closed cell polypropylene foam. 
   
   
       19 . The golf practice mat of  claim 17  wherein said backing is comprised of an open weave material having a pick count within the range of 11-22 stitches per 3 inches. 
   
   
       20 . The golf practice mat of  claim 17  wherein said first and second plurality of fibers define a turf having a density within the range of 1600-3300 ounces per cubic yard. 
   
   
       21 . The golf practice mat of  claim 15  wherein said first plurality of elongated fibers are comprised of polyethylene and said backing is comprised of an open weave material having a pick count within the range of 11-22 stitches per 3 inches. 
   
   
       22 . The golf practice mat of  claim 17  wherein said first and second plurality of fibers comprise a turf, said turf having a gauge within the range of about 0.375-0.500 in. and wherein said first plurality of fibers define a pile height of about 0.750 in.
