ABSTRACT:
A carpeting material of nonwoven synthetic thermoplastic resin fibers, capable of being folded so as to fit onto sharply irregular surfaces such as car trunk liners, made by the process of needle-looming a nonwoven carpeting material having higher and lower melting temperature synthetic thermoplastic resin fibers, subjecting the material to sufficient heat to soften and subsequently harden and rigidify one side of the carpeting, and then punching two substantially parallel rows of regularly spaced slots in the back side of the carpeting material. The slots of one row are arranged so that they are staggered in relation to the slots of the parallel row. The arrangement of slots in the back side of the carpeting enables it to be sharply folded while maintaining tear resistance.
