Abstract
Abstract A fleece fabric is produced by first consolidating a fleece into a primary fabric by fleece knitting, and then stitch bonding the primary fabric with warp yarn. The fabric is at least as strong and stable as ordinary stitch bonded fabrics, but has substantially improved pilling and abrasion resistance, and a much wider range of patterning and surface texture possibilities.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
57 words
A method for producing a fleece fabric comprising the steps of: a. consolidating a fleece into a primary fabric by fleece knitting said fleece with a first set of stitches formed solely from groups of fibers of said fleece; and b. subsequently stitch bonding the primary fabric with a second independent set of stitches of warp yarn.
Claim 2
Independent Claim
57 words
A method for producing a fleece fabric comprising the steps of: a. consolidating a fleece into a primary fabric by fleece knitting said fleece with a first set of stitches formed solely from groups of fibers of said fleece; and b. subsequently stitch bonding the primary fabric with a second independent set of stitches of warp yarn.
Claim 3
Dependent Claim
18 words
A method in accordance with claim 1, wherein the fleece knitting and warp yarn steps are performed discontinuously.
Claim 4
Dependent Claim
36 words
A method in accordance with claim 2, wherein said primary fabric is fed through said warp yarn stitch bonding step in the opposite direction to that in which it was produced in the fleece knitting step.
Claim 5
Dependent Claim
33 words
A method in accordance with claim 1, wherein the primary fabric is fed through said warp yarn stitch bonding step in the same direction as it was produced in the fleece knitting step.
Claim 6
Dependent Claim
22 words
A method in accordance with claim 1, wherein the step of consolidating results in the primary fabric having loops on both faces.
Claim 7
Dependent Claim
19 words
A method in accordance with claim 1, wherein pile loops are formed during the warp yarn stitch bonding step.
Claim 8
Dependent Claim
24 words
A method in accordance with claim 1, wherein the primary fabric is stitch bonded to at least one other fabric with said warp yarn.
Claim 9
Dependent Claim
28 words
A method in accordance with claim 1, including the step of preselecting the tensions of the warp yarns to produce patterning and surface texture effects in the fabric.
Claim 10
Independent Claim
61 words
A method of producing a fleece fabric comprising the steps of a. producing a fleece b. consolidating said fleece into a primary fabric by fleece knitting said fleece with a first set of stitches solely consisting of groups of fibers of said fleece, and c. subsequently stitch bonding the primary fabric with a second independent set of stitches of warp yarn.
Claim 11
Independent Claim
61 words
A method of producing a fleece fabric comprising the steps of a. producing a fleece b. consolidating said fleece into a primary fabric by fleece knitting said fleece with a first set of stitches solely consisting of groups of fibers of said fleece, and c. subsequently stitch bonding the primary fabric with a second independent set of stitches of warp yarn.
Claim 12
Dependent Claim
21 words
A method in accordance with claim 9, wherein the step of consolidating said fleece is done continuously with the production thereof.
Claim 13
Dependent Claim
20 words
A method in accordance with claim 10, wherein the fleece knitting and warp yarn stitch bonding steps are performed discontinuously.
Claim 14
Dependent Claim
44 words
A method in accordance with claim 1, wherein the primary fabric produced by the step of consolidating has a plain side and a loop side, and the step of stitch bonding the primary fabric comprises stitches having a plain side and a loop side.
Claim 15
Dependent Claim
33 words
A method in accordance with claim 12, wherein the warp yarn stitch bonding is carried out in such manner that the warp yarn stitch loop side is on the primary fabric plain side.
Claim 16
Dependent Claim
33 words
A method in accordance with claim 12, wherein the warp yarn stitch bonding is carried out in such manner that the warp yarn stitch loop side is on the primary fabric loop side.
Claim 17
Dependent Claim
67 words
A fleece fabric formed from a fleece, comprising: a fleece knitted primary fabric having a first set of stitches solely consisting of groups of fibers of said fleece; and having a second set of stitches of warp yarn independent of, and disposed over, said first set of stitches at least some of the stitches of said second set being non-coincident with the stitches of said first set.
Claim 18
Dependent Claim
67 words
A fleece fabric formed from a fleece, comprising: a fleece knitted primary fabric having a first set of stitches solely consisting of groups of fibers of said fleece; and having a second set of stitches of warp yarn independent of, and disposed over, said first set of stitches at least some of the stitches of said second set being non-coincident with the stitches of said first set.
Claim 19
Dependent Claim
35 words
A fleece fabric in accordance with claim 15, wherein the stitches have a first stitch length, said fabric being overstitched with warp yarn stitches having a second stitch length different from said first stitch length.
Claim 20
Dependent Claim
33 words
A fleece fabric in accordance with claim 15, wherein the stitches are to a first gauge, said fabric being overstitched with warp yarn stitches to a second gauge different from said first gauge.
Claim 21
Dependent Claim
72 words
A fleece fabric formed from a fleece comprising: a fleece knitted primary fabric having a first set of stitches solely consisting of groups of fibers of said fleece; and at least one other fabric, said primary fabric and said other fabric being bonded together with a second independent set of warp yarn stitches at least some of the stitches of said second set being non-coincident with the stitches of said first set.
Claim 22
Dependent Claim
72 words
A fleece fabric formed from a fleece comprising: a fleece knitted primary fabric having a first set of stitches solely consisting of groups of fibers of said fleece; and at least one other fabric, said primary fabric and said other fabric being bonded together with a second independent set of warp yarn stitches at least some of the stitches of said second set being non-coincident with the stitches of said first set.
