ABSTRACT:
An improved coherently bonded, low density matting article composed of a primary matting layer in which synthetic fiber-forming thermoplastic macrofilaments are irregularly looped and intermingled in a highly porous or open peak and valley three-dimensional sheet structure, preferably having peaks, humps or projections in a waffle-like pattern, and a secondary footing layer or "sole" applied and fused or bonded by its surface filaments to some of the filaments in the peak portions on one face of the primary matting layer. A special process and apparatus are provided to produce this matting article wherein transverse strength is increased while maintaining a low apparent density and further improving its filling characteristics for use as a soil retention matting.
