Abstract
Abstract A three-bar warp knitted fabric having a brushable pile surface at its technical face and a satin-like surface at its technical back is produced on a three-bar warp knitting machine by knitting overfed pile yarns on the machine's bottom bar to produce brushable pile loops at the fabric's technical face, knitting satin-effect yarns on the machine's middle bar in extended underlaps to produce a satin-like technical back of the fabric and knitting relative smaller denier tie-down yarns on the machine's top bar in a chain stitch pattern to also extend at the fabric's technical back in crossing relationship to the satin-effect yarn underlaps to shield them from picking without significantly obstructing their satin-like appearance.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
129 words
A warp knitted fabric of an at least three-bar construction characterized by a brushable surface on the technical face of said fabric and a satin-like surface on the technical back of said fabric, said fabric comprising a set of pile yarns warp knitted in overfed needle loops at the technical face of said fabric forming a brushable pile surface, a set of yarns warp knitted in extended underlaps at the technical back of said fabric forming a satin-like surface effect, and a set of tie-down yarns of substantially smaller denier than said satin yarns and warp knitted at the technical back of said fabric in substantially shorter underlaps than said satin-effect yarns for shielding said satin-effect yarns from picking without significantly obstructing the satin-like appearance of said satin-effect yarns.
Claim 2
Dependent Claim
129 words
A warp knitted fabric of an at least three-bar construction characterized by a brushable surface on the technical face of said fabric and a satin-like surface on the technical back of said fabric, said fabric comprising a set of pile yarns warp knitted in overfed needle loops at the technical face of said fabric forming a brushable pile surface, a set of yarns warp knitted in extended underlaps at the technical back of said fabric forming a satin-like surface effect, and a set of tie-down yarns of substantially smaller denier than said satin yarns and warp knitted at the technical back of said fabric in substantially shorter underlaps than said satin-effect yarns for shielding said satin-effect yarns from picking without significantly obstructing the satin-like appearance of said satin-effect yarns.
Claim 3
Dependent Claim
31 words
A warp knitted fabric according to claim 1 and characterized further in that said brushable pile surface is brushed to produce a plush surface on the technical face of said fabric.
Claim 4
Dependent Claim
24 words
A warp knitted fabric according to claim 1 and characterized further in that said tie-down yarns are warp knitted in a chain stitch pattern.
Claim 5
Dependent Claim
32 words
A warp knitted fabric according to claim 1 and characterized further in that said satin-effect yarns have a relatively bright surface lustre and said pile yarns have a relatively dull surface lustre.
Claim 6
Dependent Claim
23 words
A warp knitted fabric according to claim 1 and characterized further in that said satin-effect and pile yarns are of generally comparable denier.
Claim 7
Dependent Claim
22 words
A warp knitted fabric according to claim 1 and characterized further in that said satin-effect and pile yarns are multifilament synthetic yarns.
Claim 8
Dependent Claim
26 words
A warp knitted fabric according to claim 1 and characterized further in that said tie-down yarns are of approximately one-half the denier of said satin-effect yarns.
Claim 9
Dependent Claim
48 words
A warp knitted fabric according to claim 1 and characterized further in that said pile yarns are warp knitted in a 0,1-2,1 stitch pattern, said satin-effect yarns are warp knitted in a 1,0-3,4 stitch pattern, and said tie-down yarns are warp knitted in a 1,0-0,1 chain stitch pattern.
Claim 10
Independent Claim
169 words
A method of producing a warp knitted fabric of at least three-bar construction having a brushable surface on the technical face of said fabric and a satin-like surface on the technical back of said fabric, said method comprising: providing a warp knitting machine having at least top, middle and bottom yarn guidebars; warp knitting a set a pile yarns on said bottom bar of said machine inn overfed needle loops at the technical face of said fabric forming a brushable pile surface; simultaneously warp knitting a set of yarns on said middle bar of said machine in extended underlaps at the technical back of said fabric forming a satin-like surface effect; and simultaneously warp knitting on said top bar of said machine a set of tie-down yarns of substantially smaller denier than said satin-effect yarns in substantially smaller underlaps than said satin-effect yarns at the technical back of said fabric; said tie-down yarns shielding said satin-effect yarns from picking without significantly obstructing the satin-like appearance of said satin-effect yarns.
Claim 11
Independent Claim
169 words
