堆積し易くなり、特に前記細粉状のものと相まった場合
には、積層された熱可塑性合成樹脂粒の表面の均一性を
さらに欠く要因となる。For example, if the angle of repose is large, it tends to be deposited on the lower end of the comma doctor because the bridging property of the thermoplastic synthetic resin particles is high, and especially when it is combined with the fine powder, it is laminated. It becomes a factor that further lacks the uniformity of the surface of the thermoplastic synthetic resin particles.

る。The present invention supplies thermoplastic resin particles including those having a small particle diameter to a large particle diameter onto a surface of a base material layer from a feeder having a doctor knife to form thermoplastic synthetic resin particles on the base material layer. After applying, and then heating and pressurizing this, the thermoplastic synthetic resin particle layer is fused to the base material layer, and at the same time, the thermoplastic synthetic resin particles are fused and integrated with each other and crushed. In the manufacturing method, there is provided a method for manufacturing an interior material using a thermoplastic synthetic resin particle having a repose angle of 60 ° or less and a doctor knife having a wedge shape and a blade edge thickness of 5 mm or less. To do.
