Abstract
Disposable mat material comprising an abrasion resistant pervious layer of a non-woven web of bonded filaments and an absorbent layer of microfibres, the pervious and absorbent layers being bonded intermittently, characterized in that the bonds penetrate through the pervious layer and join the fibres in that layer with those in the absorbent layer. Thus water, for example, on the feet of a user, rapidly penetrates to the absorbent layer from the outer abrasion resistant layer. The bond areas not only aid the rapid absorbence, but also provide `pockets` giving an enhanced roughness.
