Abstract: The present invention provides an automotive inner ceiling material difficult to deform at a high temperature. Sheath-core type conjugate polyester fibers are prepared. The sheath is a heat fusible component. The core is a non heat fusible component. The sheath is made of copolyester which comprises acid units made of terephthalic acid and diol unites made of ethylene glycol and 1,4-butanediol. The conjugate fibers and the main fibers of polyester are mixed and provided in a card machine to be opened and accumulated to obtain a fibrous web. The fibrous web is heated to melt the sheaths, which are thereafter solidified to bind the fibers to obtain a non woven fabric.

Immediately thereafter, the nonwoven fabric is heat-molded between a pair of a mold plates. During the heat-molding process, the inner temperature is maintained at 100˜130° C. for 60 seconds to obtain the ceiling material.
