Zusammenfassung:	This fabric-like material (1) for reinforcement in urethane foam molding is obtained by impregnating a part of the surface of an nonwoven fabric (2) of organic fibers with a hot melt magnetic material (3) and immobilizing the hot melt magnetic material (3). This fabric-like material (1) for reinforcement in urethane foam molding is characterized in that the hot melt magnetic material (3) satisfies the composition described below, while having a softening point of from 70°C to 100°C (inclusive). An ethylene-vinyl acetate copolymer (A): from 10% by mass to 95% by mass (inclusive) A wax (B): from 0% by mass to 30% by mass (inclusive) A magnetic powder (C): from 5% by mass to 70% by mass (inclusive) (In this regard, the total of the components (A), (B) and (C) is taken as 100% by mass.) L'invention concerne un matériau de type tissu (1) destiné au renforcement lors du moulage de mousse d'uréthane et obtenu par imprégnation d'une partie de la surface d'un non-tissé (2) de fibres organiques à l'aide d'un matériau magnétique thermofusible (3) et par immobilisation du matériau magnétique thermofusible (3). Ce matériau de type tissu (1) destiné au renforcement lors du moulage de mousse d'uréthane est caractérisé en ce que le matériau magnétique thermofusible (3) satisfait la composition décrite ci-dessous, tout en ayant un point de ramollissement de 70 °C à 100 °C (inclus). Un copolymère éthylène-acétate de vinyle (A) : de 10 % en masse à 95 % en masse (inclus); une cire (B) : de 0 % en masse à 30 % en masse (inclus); une poudre magnétique (C) : de 5 % en masse à 70 % en masse (inclus) (à cet égard, le total des composants (A), (B) et (C) est considéré comme 100 % en masse). ウレタン発泡成形用補強用布状物（１）は、有機繊維の不織布（２）の表面の一部に、ホットメルト磁性物（３）が浸み込み、固定化されている。ホットメルト磁性物（３）が、下記組成を満たし、かつ軟化点が７０℃以上１００℃以下であることを特徴とする。エチレン－酢酸ビニル共重合体（Ａ）：１０質量％以上９５質量％以下、ワックス（Ｂ）：０質量％以上３０質量％以下、磁性体粉末（Ｃ）：５質量％以上７０質量％以下。（但し、前記（Ａ）、（Ｂ）および（Ｃ）の合計を１００質量％とする。）
