Abstract

A cable wrap which swells upon contact with water is made by coating one side of a nonwoven fabric support with a polyvinyl alcohol binding agent and then with a superabsorber powder, drying the coated fabric between contact surfaces, printing a polyacrylate binding agent plaste onto the superabsorber surface, and then drying the coated fabric. Alternatively, the cable wrap can be made by printing a polyacrylate binding agent paste onto a nonwoven fabric support, applying a polyvinyl alcohol binding agent onto the polyacrylate binding agent paste, sprinkling superabsorber powder onto the polyvinyl alcohol binding agent, and drying the coated fabric between contact surfaces.
