摘要：
The present invention provides a reinforcing material for urethane foam which effectively protects a molded urethane foam body and suppresses fricatives with a metal spring, having high productivity and excellent handleability and being applicable to a molded urethane foam body with highly uneven shape at low cost.It is a reinforcing material for urethane foam wherein a nonwoven fabric A having single fiber linear density of 1.0 to 3.0 dtex and a nonwoven fabric B having single fiber linear density of 0.5 to 2.5 dtex are laminated by needlepunching process by inserting needles from a direction of the nonwoven fabric A with a needle density of 35 to 70 needles/cm2.
摘要（中）：
本发明提供了一种用于聚氨酯泡沫的增强材料，其有效地保护模制的聚氨酯泡沫体，并且用金属弹簧抑制摩擦擦，具有高生产率和优异的可操作性，并且可以低成本地应用于具有高度不均匀形状的模制聚氨酯泡沫体。 作为聚氨酯泡沫塑料的增强材料，其中单丝纤维线密度为1.0〜3.0dtex的无纺布A和单纤维线密度为0.5〜2.5dtex的无纺布B通过针刺方法层叠， 针密度为35〜70针/ cm 2的无纺布A。
