REINFORCED WEB OF NON-WOVEN MATERIAL, COMPLEX CONTAINING SUCH WEB, AND METHOD OF NON-WOVEN MATERIAL WEB PROCESSING Russian patent published in 2019 - IPC D04H1/49 

FIELD: textile.

SUBSTANCE: invention relates to a nonwoven material web (10) comprising at least one reinforcement zone (20a, 20b, 20c, 20d), in which the fibres and/or threads forming the web are connected in accordance with reinforcement pattern (22) comprising a plurality geometric shapes (24), wherein the reinforcement zone is located along the entire length (L) of the web, measured in the longitudinal direction (X1), and width (l1, l2), strictly less than web width (l) measured in lateral direction (Y1) orthogonal to longitudinal direction (X1). Web (10) also comprises at least one non-reinforced zone. Strengthened zone extension (20a, 20b, 20c, 20d) under action of said force acting in longitudinal direction of web (10) is less than elongation of non-reinforced zone under action of the same force considering connection between fibres and/or threads.

EFFECT: such web (10) can be used, in particular, for production of multilayer complex.
