Door mat and a method of manufacture thereof

A door mat comprising a three-layer integral mass of mutually fused and bonded loops of synthetic resin monofilaments, said mat comprising:

• (a) a bottom anti-slip layer (S) consisting of a lattice shaped arrangement having a plurality of open spaces (19) which open spaces (19) are adapted to receive and contain mud or dirt that is deposited on the top of the mat and which filtered downwardly through the mat,
• (b) a top surface layer (A) that has an arrangement of concave depressions in its otherwise planar surface, said depressions presenting a patterned concave-convex design appearance in the top surface layer (A), and
• (c) an intermediate layer (L) sandwiched between said bottom anti-slip layer (S) and said top surface layer (A),
• wherein the size or shapes of the loops in said three layers being progressively larger from the bottom anti-slip layer through the intermediate layer to the top surface layer, and whereby mud deposited on said top surface (A) passes downwardly through said intermediate layer (L) and into said open spaced (19) of said bottom anti-slip layer (S) to thus insure that the mud is not scattered outside the perimeter of the door mat.
