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.
