TACKY ADHESIVE TAPE SUBSTRATE AND TACKY ADHESIVE TAPE PRODUCED BY USING THE SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To obtain a tacky adhesive tape substrate free from contaminating the construction site by a coating material fallen off from the surface of a tacky adhesive tape for curing by making the substrate has a structure composed of a woven fabric laminated to a nonwoven fabric with a thermoplastic resin. SOLUTION: The objective substrate 6 is produced by laminating a woven fabric 4 (preferably a rayon cloth) to a nonwoven fabric 2 (preferably a fabric free from binder and having a basis weight of 10-200 g/m2, e.g. a nonwoven cotton fabric) with a thermoplastic resin 3 (preferably a polyethylene). The tape 7 for curing can be produced by applying a tacky adhesive layer 5 on the above woven fabric 4 of the above tacky adhesive tape substrate 6 and applying a releasing agent layer 1 on a face of the tape substrate 6 opposite to the face coated with the above tacky adhesive layer 5.
