Abstract: Composite matting comprises a matting web with a peak-and-valley structure and a reinforcement in the form of a filament and/or ribbon system, which is used as a supporting base for the coating of walls. The reinforcement consists of glass filaments, aramide filaments, silica filaments, metal or synthetic polymer filaments and/or ribbons and acts in the direction of loading, during which it either prevents a change in shape or is limited to a prefixed mass in order to adjust the thickness of the composite matting.

Abstract: A low density matting structure of improved transverse strength obtained by vertically laying continuous melt-spun thermoplastic macrofilaments (diameter=0.1-1.5 mm) onto a horizontally moving profiled support in overlapping rows of irregularly looped filaments to form a peak and valley three-dimensional structure undulating in its longitudinal and/or transverse direction. The matting articles consist essentially of the melt-spun filaments which are self-bonded or fused at random points of intersection without using any bonding agent or reinforcing inserts, and the resulting matting is especially distinguished by a high transverse strength per unit of surface weight of at least 2 Nm/g and preferably 4 Nm/g.

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.

Abstract: A mat material suitable for use for reinforcing plastics, as an upholstery material, filter material and various other purposes is made by melt spinning a synthetic polymeric material onto a moving embossed surface where the filaments become melt fused together at mutual points of contact. A gas or gas producing substance is mixed with the melt prior to extrusion to produce a plurality of adjacent, separate, discontinuous cavities in the filament.

Abstract: A porous, reinforced, erosion control matting is provided by a relatively open, self-supporting, three-dimensionally looped structure of synthetic filaments having a diameter of at least 0.06 mm., with a backing of a decay-resistant or rot-resistant, comparatively dense web or fabric which is bonded to at least some of the filaments of the matting, and with a lattice or open-mesh reinforcing facing member extending parallel to the backing to provide an upper surface of crossbars onto which the looped synthetic filaments are laid so as to be interlocked with the crossbars while extending downwardly between the crossbars to form porous alveolate cells. The matting is highly useful in preventing soil erosion while also being easily manufactured and installed in any given location.
