    Patent number: 3992904
    Abstract: A stitch-bonded non-woven fabric of the kind comprising a web of fibers stitch-bonded by wales of chain stitch loops on one side of the fabric which are interconnected on the other side of the fabric by stitch laps is described. In a first group of succeeding courses the wales are connected by stitch laps in sets which are not connected by stitch laps to wales in adjacent sets, so that the web stands out between adjacent sets in longitudinal stripes. In a second group of succeeding courses at least one of the wales in a set in the first group of courses is connected by stitch laps to a wale outside the said set so that in the second group of courses the said longitudinal stripes are broken and the second group of courses appear as a transverse bar in which there are no longitudinal stripes in which the web stands out.
