ABSTRACT:
A continuous, spliceless bias fabric in which the angular displacement between the warp and filling yarns is in the approximate range of 90 to 150 degrees is produced by the steps of cutting a tubular, square-woven fabric at a bias angle of 40-50 degrees to provide a continuous length of fabric, optionally drying the fabric, calendering at least one layer of an elastomeric compound to at least one side of the continuous length of fabric, heating the thus-calendered fabric, stretching the fabric in its width direction to provide a warp to filling angle of about 90-150 degrees, and cooling the stretched fabric.
