Abstract
Novel CD-tearable non-woven fabrics having striations or other patternwise areas of substantially depthwise bonding of the fibers whereby the fabric is characterized as being tearable substantially evenly in the unbonded areas, the fabric further being characterized as having substantially greater tensile strength in the MD than is obtainable after manufacture of the fabric and prior to bonding. Preferably, patternwise bonded areas are provided by impregnating the fabric with a bonding agent. This invention further includes adhesive tape and other products employing the aforementioned non-woven fabrics.
