ABSTRACT:
A pressure-sensitive adhesive tape or sheet having a pressure-sensitive adhesive layer formed on at least one surface of the support thereof, wherein the surface of the pressure-sensitive adhesive layer on at least one surface of the support partly has projected spots of fibers. The projected spots of fibers are preferably raised spots of fibers that are raised from the surface of the pressure-sensitive adhesive layer. The pressure-sensitive adhesive tape or sheet is favorable for flooring material fixation. The pressure-sensitive adhesive tape or sheet is produced according to a flocking method that comprises flocking the surface of the pressure-sensitive adhesive layer on at least one surface of the support to thereby form projected spots of fibers partly in the surface of the pressure-sensitive adhesive layer.
