Abstract
Abstract The composite upholstery fabric includes a loosely woven or open type fabric, a nonwoven scrim backing with fibers of the woven fabric being needled into and through the nonwoven scrim, and a latex coating adhered to and at least partially penetrating the nonwoven scrim to lock the fibers of the woven fabric in position and to aid in preventing separation of the woven fabric and the nonwoven scrim. The composite upholstery fabric has a good stability and is sufficiently flexible that the fabric may be easily positioned on various sharp turns and corners of upholstered furniture.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
A composite upholstery fabric comprising (a) a woven or knitted fabric having an upper face and a lower face, (b) a nonwoven scrim including upper and lower faces with said upper face positioned against said lower face of said fabric, (c) fibers of said fabric being needled into said nonwoven scrim with portions of said needled fibers of said fabric extending through said lower face of said nonwoven scrim and being flattened thereagainst, and (d) a coating adhered to said lower face of said nonwoven scrim and encapsulating the portions of said fibers of said fabric which extend through and are flattened against said lower face of said nonwoven scrim to lock said fibers in place and aid in preventing separation of said fabric and said nonwoven scrim, said coating also penetrating said nonwoven scrim and penetrating at least partially into said lower face of said fabric to further aid in preventing separation of said fabric and said nonwoven scrim.
Claim 2
Dependent Claim
160 words
A composite upholstery fabric comprising (a) a woven or knitted fabric having an upper face and a lower face, (b) a nonwoven scrim including upper and lower faces with said upper face positioned against said lower face of said fabric, (c) fibers of said fabric being needled into said nonwoven scrim with portions of said needled fibers of said fabric extending through said lower face of said nonwoven scrim and being flattened thereagainst, and (d) a coating adhered to said lower face of said nonwoven scrim and encapsulating the portions of said fibers of said fabric which extend through and are flattened against said lower face of said nonwoven scrim to lock said fibers in place and aid in preventing separation of said fabric and said nonwoven scrim, said coating also penetrating said nonwoven scrim and penetrating at least partially into said lower face of said fabric to further aid in preventing separation of said fabric and said nonwoven scrim.
Claim 3
Dependent Claim
26 words
A composite upholstery fabric according to claim 1 wherein said fabric is woven and said nonwoven scrim is of a lesser thickness than said woven fabric.
Claim 4
Dependent Claim
44 words
A composite upholstery fabric according to claim 2 wherein said woven fabric is of an open or loose weave including a range of from four to seven picks per inch and having a weight of from about three to ten ounces per square yard.
Claim 5
Dependent Claim
25 words
A composite upholstery fabric according to claim 2 wherein said nonwoven scrim is within the range of about 0.3 to 3 ounces per square yard.
Claim 6
Dependent Claim
28 words
A composite upholstery fabric according to claim 2 wherein said woven fabric is needled to said nonwoven scrim with approximately 200 to 600 needle penetrations per square inch.
Claim 7
Dependent Claim
39 words
A composite upholstery fabric according to claim 2 wherein said coating is latex and is applied to the lower face of said nonwoven scrim in an amount within the range of about one to six ounces per square yard.
Claim 8
Independent Claim
164 words
A method of forming a composite upholstery fabric comprising the steps of (a) moving a woven or knitted fabric having an upper face and a lower face along a predetermined path of travel, (b) passing a nonwoven scrim in juxtaposition along said given path of travel with the upper face of the nonwoven scrim positioned against the lower face of the fabric, (c) needling said juxtapositioned fabric and nonwoven scrim while forcing fibers of the fabric into and through the nonwoven scrim, and (d) applying a coating to said lower face of the nonwoven scrim to encapsulate the portions of the fibers of the fabric which extend through the lower face of the nonwoven scrim to lock the fibers in place and aid in preventing separation of the fabric and the nonwoven scrim, and while also penetrating the nonwoven scrim and at least partially into the lower face of the fabric to further aid in preventing separation of the fabric and the nonwoven scrim.
Claim 9
Independent Claim
164 words
A method of forming a composite upholstery fabric comprising the steps of (a) moving a woven or knitted fabric having an upper face and a lower face along a predetermined path of travel, (b) passing a nonwoven scrim in juxtaposition along said given path of travel with the upper face of the nonwoven scrim positioned against the lower face of the fabric, (c) needling said juxtapositioned fabric and nonwoven scrim while forcing fibers of the fabric into and through the nonwoven scrim, and (d) applying a coating to said lower face of the nonwoven scrim to encapsulate the portions of the fibers of the fabric which extend through the lower face of the nonwoven scrim to lock the fibers in place and aid in preventing separation of the fabric and the nonwoven scrim, and while also penetrating the nonwoven scrim and at least partially into the lower face of the fabric to further aid in preventing separation of the fabric and the nonwoven scrim.
Claim 10
Dependent Claim
61 words
A method according to claim 7 wherein the fabric is woven and the nonwoven scrim is of lesser thickness than the woven fabric, and including the step of calendering the needled juxtapositioned woven fabric and nonwoven scrim to flatten the portions of the fibers extending through the lower face of the nonwoven scrim prior to the step of applying the coating.
