Abstract: A composite bulky fabric of narrow width having lengthwise extensibility and widthwise dimensional stability in which the fabric is made up of a plurality of flattened tubular-knit components disposed in edge-to-edge juxtaposed position and interconnected by seams extending along the junction and formed of a zigzag line of stitching, the knitted tubular components being formed of a non-run stitch comparable to a tricot stitch formation. The tubular knit components are preferably knit on a small diameter knitting machine having a reciprocating feed for each of the needles so that the feed reciprocates between a pair of adjacent needles, and is supplied from a creel or other stationary supply.The products made in accordance with the invention are useful for thermal and electrical insulating, gasketing, padding, sealing and similar purposes.The novel method for producing the fabric is diagrammed in FIG. 6.
