PROBLEM TO BE SOLVED: To provide a method of manufacturing a reinforcing material made of a fabric hard to release a core component from a sheath component, having the sheath component uniformly in the fabric, and capable of solidly adhering to a wall of a container.;SOLUTION: A multifilament yarn is obtained by a conjugate melt-spinning method, the multifilament yarn composed of a core-sheath type conjugate fiber composed of polyamide as a core component, and a maleic acid-modified polyolefin as a sheath component. A mixed resin of malic acid-modified polyolefin and high-density polyethylene may be used as a sheath component. A stretched multifilament yarn is obtained by cooling the multifilament, and thereafter subjecting to stretch processing under heating. A fabric is obtained using the stretched multifilament yarn. The fabric is bonded to the wall of the resin container by attaching the fabric on a wall of a resin container, and heating and pressurizing to soften or melt. Thus. the resin container is reinforced.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
