To provide an interior trim material for a vehicle equipped with a proper degree of draftiness and sound absorbing performance by investigating the relation between the draftiness and the absorbing sound and giving the desired degree of draftiness to a film so that it possesses a common sound absorbing function with a short fiber film.
A non-woven laminate is formed by laminating a surface layer 1 of knit form and a short fiber non-woven cloth 2 one over another, in which the knit and the short fiber non-woven cloth layer are adhered together by a hot fusion attachment sheet 3, wherein the draftiness ranges between 0.1-30.0 cc/cm2/sec, the bending resistance is no more than 200 mm, and the initial expansion modulus of elasticity lies in the range 150-2500 N/50 mm/100%, and from this laminate material the intended interior trim material for vehicle is accomplished equipped with excellent sound absorbing performance.
