Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
158 words
A warp knitted stretch fabric capable of balanced bi-directional stretch having in combination an inelastic knitted ground structure and elastic lay in, said ground structure comprising a plurality of courses and wales formed from single stitches, said single stitches being deposed in a six stitch repeating pattern, the first three stitches of said six stitch repeating pattern traversing diagonally to adjacent wales and courses, the fourth stitch of said six stitch repeating pattern being knitted in the same wale and adjacent course as the third stitch of said six stitch repeating pattern, the fifth and sixth stitches of said six stitch repeating pattern traversing diagonally from said fourth stitch to adjacent wales and courses said diagonally traversing being in a direction opposite that of the traversing of said first, second and third stitches, and an elastic thread extending through said ground structure and being held into said ground structure by the unknitted portions of said inelastic ground structure.
Claim 2
Dependent Claim
