Abstract
The flame retardant sheet material of the present invention simultaneously affords good flame retardancy and melting resistance in a sheet material in which a nonwoven is used, and also simultaneously provides good abrasion resistance and an excellent design, making it suitable for use in automotive trim surface materials. A flame retardant sheet material is obtained by first needle-punching and then stitch-bonding a web containing 70 to 95 wt % base fiber and 5 to 30 wt % flame retardant fiber selected from among flame retardant rayon fiber and modacrylic fiber. It is preferable for propoxyphosphazene or another such phosphoric ester-based flame retardant to be kneaded into the flame retardant fiber. It is also preferable to add a binder fiber to the web in order to improve abrasion resistance.
