Abstract
Abstract A warp knitted fabric employs a warp knitted pattern as the ground stitches. In this novel fabric there are reinforcing threads of a substantially rigid material. The weft threads may run parallel to each other and are located between the needle loops of stitch rows that follow each other sequentially in the warping direction. Additionally, there are two sets of diagonal threads both of which run alternatively: (a) between two needle loops of neighboring wales and (b) between two needle loops of successive stitch rows. Laid-in warp threads may be provided between needle loops of adjacent wales. There is thus provided a fabric having higher rigidity in all directions.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
115 words
A fabric enmeshed by stitched ground ware, comprising: a plurality of wales of warp thread stitched by rows; a plurality of parallel, inlaid weft threads, each laid-in across said wales and between two adjacent rows of stitch loops in said warp thread, said rows of stitch loops being transverse to said warp thread; and a first and second plurality of diagonally inlaid threads, said first plurality crossing said second plurality, each of the inlaid threads of said first and second plurality running alternatively and repetitively: (a) between two stitch loops of a corresponding adjacent pair of said wales and (b) between two stitch loops of two successive rows of stitch loops of said warp threads.
Claim 2
Dependent Claim
115 words
A fabric enmeshed by stitched ground ware, comprising: a plurality of wales of warp thread stitched by rows; a plurality of parallel, inlaid weft threads, each laid-in across said wales and between two adjacent rows of stitch loops in said warp thread, said rows of stitch loops being transverse to said warp thread; and a first and second plurality of diagonally inlaid threads, said first plurality crossing said second plurality, each of the inlaid threads of said first and second plurality running alternatively and repetitively: (a) between two stitch loops of a corresponding adjacent pair of said wales and (b) between two stitch loops of two successive rows of stitch loops of said warp threads.
Claim 3
Dependent Claim
26 words
A fabric according to claim 1 further comprising: a plurality of inlaid longitudinal threads, each laid-in between stitch loops of a corresponding adjacent pair of wales.
Claim 4
Dependent Claim
26 words
A fabric according to claim 2 wherein said first and second plurality of diagonally inlaid threads are sandwiched between said weft threads and said longitudinal threads.
Claim 5
Dependent Claim
21 words
A fabric according to claim 2 wherein said longitudinal threads are sandwiched between said weft threads and said diagonally inlaid threads.
Claim 6
Dependent Claim
20 words
A fabric according to claim 2 wherein said wales of warp thread are formed into a plurality of chain stitches.
Claim 7
Dependent Claim
20 words
A fabric according to claim 2 wherein said wales of warp thread are formed into a plurality of tricot stitches.
Claim 8
Dependent Claim
38 words
A fabric according to claim 1 wherein said weft threads and said diagonally inlaid threads are positioned to leave openings that allow stitching of said warp threads without piercing of said weft thread or said diagonally inlaid thread.
Claim 9
Dependent Claim
24 words
A fabric according to claim 7 wherein said weft threads and said diagonally inlaid threads are substantially thicker and stronger than said warp threads.
Claim 10
Dependent Claim
20 words
A fabric according to claim 8 wherein said fabric is coated with a synthetic material to form a laminated structure.
Claim 11
Independent Claim
115 words
A method for forming a fabric with warp thread, weft thread and diagonal thread, comprising the steps of: laying-in said weft threads in a given series of transverse rows; laying-in said diagonal thread in a first series of diagonal rows, each crossing said weft threads at an acute angle; laying-in said diagonal thread in a second series of diagonal rows, each crossing said weft threads at an acute angle, the diagonal thread of said second series crossing that of said first series; and stitching said warp thread about said weft and diagonal threads to form a ground ware, said stitching forming spaced stitch loops between the diagonal thread of both said first and second series.
Claim 12
Independent Claim
115 words
A method for forming a fabric with warp thread, weft thread and diagonal thread, comprising the steps of: laying-in said weft threads in a given series of transverse rows; laying-in said diagonal thread in a first series of diagonal rows, each crossing said weft threads at an acute angle; laying-in said diagonal thread in a second series of diagonal rows, each crossing said weft threads at an acute angle, the diagonal thread of said second series crossing that of said first series; and stitching said warp thread about said weft and diagonal threads to form a ground ware, said stitching forming spaced stitch loops between the diagonal thread of both said first and second series.
Claim 13
Dependent Claim
39 words
A method according to claim 10 employing longitudinal thread and further comprising the step of: laying-in said longitudinal thread in a predetermined series of longitudinal rows, the step of stitching said warp threads being performed about said longitudinal thread.
Claim 14
Dependent Claim

A method according to claim 11 wherein said diagonal threads are sandwiched between said weft threads and said longitudinal threads.
Claim 15
Dependent Claim
20 words

Claim 17
Dependent Claim
22 words
A method according to claim 11 wherein the step of stitching said warp thread is conducted so as to form tricot stitches.
