摘要

PURPOSE: A liner for repairing a water supply pipe and a sewage pipe is provided to prevent the degradation of properties such as stress even if the water supply pipe and the sewage pipe have the property that a cured resin is rapidly impregnated into cylindrical non-woven fabrics. CONSTITUTION: A liner for repairing a water supply pipe and a sewage pipe comprises: cylindrical non-woven fabrics(1) having an adhesive portion(4); a fiber sheet(2) for reinforcement located at the lower end of the cylindrical non-woven fabrics; and a waterproof film(3) coated on the fiber sheet for reinforcement. The cylindrical non-woven fabrics have a structure where short fibers with the fineness of 6~15 denier are crossed with the density of 0.10~0.17g/cm^3.
