ABSTRACT:
An adhesive tape or the like is described comprising cotton warp yarns and textured polyester filler yarns having a layer of pressure sensitive adhesive disposed thereon. This invention includes the use of heavy denier textured polyester filler yarns because these yarns have the ability to spread out upon the application of pressure thereby filling the fabrics interstices thus preventing the adhesive that has been deposited on this backing fabric from penetrating through the fabric. The construction of the adhesive tape disclosed herein improve qualities such as the tear characteristics; flexibility; conformability; and blocking of the tape, while providing a tape that may be manufactured economically.
