Abstract
Abstract A stitch knitted fabric, for example a stitch bonded web of fibres, is made on a two guide bar machine with the front bar (which may exhibit missed thread patterning) knitting pillar stitches and the back bar (which may have part, for example, half set threading) forming stitches and/or laid-in sections and/or floats of thread extending over at least two wales of the front bar system and repeating over not less than four courses, the back bar system distorting, through thread tension, the front bar system and/or filling to give a pattern or texture effect.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
92 words
A two guide bar stitch knitted fabric comprising a filling and front and back bar warp thread systems of which the front bar system comprises pillar stitches, characterised in that the back bar system repeats over not less than four courses, its threads passing between at least two wales of the front bar system, and comprises fewer stitches in a repeat than the number of courses in a repeat, the back bar system distorting, through tension in its threads, the front bar system and/or filling to give a pattern or texture effect.
Claim 2
Dependent Claim
92 words
A two guide bar stitch knitted fabric comprising a filling and front and back bar warp thread systems of which the front bar system comprises pillar stitches, characterised in that the back bar system repeats over not less than four courses, its threads passing between at least two wales of the front bar system, and comprises fewer stitches in a repeat than the number of courses in a repeat, the back bar system distorting, through tension in its threads, the front bar system and/or filling to give a pattern or texture effect.

Claim 9
Dependent Claim
36 words
A fabric according to claim 1, characterised in that single or double missed thread wale of the front bar system is crossed by floats of the back bar system to simulate a raised cable stitch formation.
