Abstract:
A method for producing a thermally expandable base material for a vehicle interior, the method includes needling a web to produce a fiber mat. The web includes an inorganic fiber, a thermoplastic resin fiber, and a thermally expandable microcapsule. The fiber mat is heated to a temperature at which the thermoplastic resin fiber is melt and which is lower than a thermal expansion starting temperature of the thermally expandable microcapsule. The fiber mat is hot-pressed. The fiber mat is cooled.
