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.
