Abstract
Abstract A warp-knitted shoe liner fabric of a three-bar construction having a three-dimensional compressible character in the fabric's thickness dimension with a pattern of elongated coursewise underlaps at the fabric's technical back which, in use, is to be oriented to face inwardly of the interior foot-receiving area of the shoe. The fabric is preferably finished with dye bath-carrying anti-microbial/anti-fungal and wicking enhancement agents, and also has silicone and acrylic polymers applied to resist fraying and abrasion and improve the fabric softness.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
A method of producing a fabric liner for a shoe, comprising the steps of warp knitting a textile fabric of an at least three-bar construction having at least three sets of yarns knitted together in needle loops arranged in longitudinally-extending wales and transversely extending courses in respective stitch patterns producing a compressible thickness to the fabric and having a pattern of elongated coursewise underlaps at the technical back of the fabric to provide a relatively soft feel to the surface thereof, and thereafter applying to the fabric abrasion-resistant, and wicking enhancement agents.
Claim 2
Independent Claim
92 words
A method of producing a fabric liner for a shoe, comprising the steps of warp knitting a textile fabric of an at least three-bar construction having at least three sets of yarns knitted together in needle loops arranged in longitudinally-extending wales and transversely extending courses in respective stitch patterns producing a compressible thickness to the fabric and having a pattern of elongated coursewise underlaps at the technical back of the fabric to provide a relatively soft feel to the surface thereof, and thereafter applying to the fabric abrasion-resistant, and wicking enhancement agents.
Claim 3
Dependent Claim
23 words
A method of producing a fabric liner for a shoe according to claim 1, and further comprising the step of dyeing the fabric.
Claim 4
Dependent Claim
38 words
A method of producing a fabric liner for a shoe according to claim 2, wherein the mildew and bacteria-resistant agent and the wicking enhancement agent are applied during dyeing as part of a common dyeing and treatment bath.
Claim 5
Dependent Claim
27 words
A method of producing a fabric liner for a shoe according to claim 1, and further comprising the step of applying heat and compression to the fabric.
Claim 6
Dependent Claim
26 words
A method of producing a fabric liner for a shoe according to claim 4, wherein the step of applying heat and compression comprises calendaring the fabric.
