ABSTRACT:
Method of producing fibrous or sheet structure comprising melt coextruding a laminated structure comprising an assembly of two or more layers from polymeric material laminated together in intimate adherence with one another and simultaneously or subsequently so treating the assembly as to produce a regular pattern of areas of strong bonding separated by areas of weak or no bonding between the layers of the assembly.
A sheet or fibrous product comprising an assembly of three or more ribbon-like elements of polymeric material with adjacent elements bonded in face-to-face relationship at regular intervals along their length.
A sheet of fibrous product comprising three or more layers of polymeric material bonded to one another into an assembly at regular intervals along the length of the assembly and in which the or at least one of the inner layers of the assembly has a shorter surface length between adjacent bonds than the outer layers of the assembly, the outer layers thus having the form of loops.
