Abstract
Abstract Novel stitch bonded fleece fabrics are made on two bar machines with the front bar knitting pillar stitch and the back bar, with incomplete e.g. half set threading, traversing adjacent wales of the front bar, the tension of the back bar threads in relation to that of the front bar threads being such as to pull adjacent wales of the pillar stitches together. The back bar threads are alternately knitted and laid in, which results in large and small loops causing the fleece fibers to bunch into weftway fiber bundles. The combination of wales pulled together and the weft effect can simulate the appearance of a leno weave fabric.
