ABSTRACT:
In a mat composed of a base cloth, a pile tufted thereto, and a rubber backing applied to the non-pile surface of the base cloth, a cotton-like layer composed of a woven cloth of a polyester textured yarn non-adherent to the rubber and a filament or staple which layer is needle-punched is used. In this mat, weakly adherent regions at which the woven cloth and the rubber portion contact each other and strong adhesive regions at which the cotton-like layer and the rubber portion content each other are formed in dots in a large distribution. Waving deformation during repeated use is prevented.
