Abstract
A floor mat has tufts made of a yarn which is formed with a monofilament core around which a multifilament yarn is air entangled. The resulting yarn is sufficiently stiff to clean dirt off of the shoes of passers by, yet is easily cleaned. The monofilament core is a polypropylene between 600 and 1200 denier, preferably about 1095 denier. The multifilament yarns entangled around the core are also polypropylene and total about 160 filaments and about 4800 denier. The air entangling is accomplished using higher than normal air pressure (i.e., about 110 p.s.i.).
