Reinforced nonwoven fabrics, assemblies comprising such fibers, and methods of processing nonwoven fabrics

摘要

The nonwoven fabric sheet 10 comprises at least one reinforcement section 20a, 20b, 20c, 20d wherein the fibers and / or filaments constituting the sheet are reinforced with a plurality of geometric shapes 24 ). The strengthening zone is defined by the width of the sheet 10 measured in the longitudinal direction X1 over the entire length L of the sheet and in the lateral direction Y1 perpendicular to the longitudinal direction X1 ) More strictly smaller width ( . Thus, the sheet 10 further comprises at least one unenhanced section 30a, 30b. Due to the coupling between the fibers and / or the filaments, the stretching of the strengthening zones 20a, 20b, 20c, 20d under the effect of a given force exerted in the longitudinal direction of the sheet 10, Less than elongation. Such sheet 10 can be used particularly for producing laminated assemblies.
