Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
148 words
A warp-knitted pile fabric comprising at least one system of warp threads consisting of chain stitches forming a plurality of wales and courses, said chain stitches having bight portions, and loop portions passing through said bight portions of adjacent chain stitches in the same wale and in an adjacent course, respectively; a system of weft threads located in said courses, between said bight portions and said loop portions of the chain stitches of the respective course; and a system of pile warp threads, each pile warp thread having alternate pile portions and anchoring portions, said pile portions extending between different wales and courses, and alternate anchoring portions being located in different wales and courses, each anchoring portion passing between the bight portions and loop portions of two adjacent chain stitches located in the same wale in two successive courses so that said pile portions form an anchored pile.
Claim 2
Dependent Claim
148 words
A warp-knitted pile fabric comprising at least one system of warp threads consisting of chain stitches forming a plurality of wales and courses, said chain stitches having bight portions, and loop portions passing through said bight portions of adjacent chain stitches in the same wale and in an adjacent course, respectively; a system of weft threads located in said courses, between said bight portions and said loop portions of the chain stitches of the respective course; and a system of pile warp threads, each pile warp thread having alternate pile portions and anchoring portions, said pile portions extending between different wales and courses, and alternate anchoring portions being located in different wales and courses, each anchoring portion passing between the bight portions and loop portions of two adjacent chain stitches located in the same wale in two successive courses so that said pile portions form an anchored pile.
Claim 3
Dependent Claim
43 words
A warp-knitted pile fabric as claimed in claim 1 wherein said alternate anchoring portions of each pile warp thread are located in adjacent courses and adjacent wales; and wherein each pile warp thread extends along a zigzag path between adjacent wales and courses.
Claim 4
Dependent Claim
36 words
A warp-knitted fabric as claimed in claim 1 wherein each weft thread is located in one of said courses, respectively, passing between said bight portions and loop portions of the chain stitches of the respective course.
Claim 5
Dependent Claim
30 words
A warp-knitted fabric as claimed in claim 1 wherein said pile portions of said pile warp threads form pile loops only on a part of the surface of the fabric.
Claim 6
Dependent Claim
29 words
A warp-knitted fabric as claimed in claim 1 wherein said wales include groups of adjacent wales, said groups being separated from each other in the direction of said courses.
Claim 7
Dependent Claim
72 words
A warp-knitted pile fabric as claimed in claim 1 wherein said alternate anchoring portions of each pile warp thread are located in adjacent courses and adjacent wales; and wherein each pile warp thread extends along a zigzag path between adjacent wales and courses; and wherein each weft thread is located in one of said courses, respectively, passing between said bight portions and loop portions of the chain stitches of the respective course.
Claim 8
Dependent Claim
51 words
A warp-knitted fabric as claimed in claim 6 wherein said pile portions of said pile warp threads form pile loops only on a part of the surface of the fabric; wherein said wales include groups of adjacent wales, said groups being separated from each other in the direction of said courses.
