FOAMED MOUNTING SYSTEMS, WHICH INCLUDE SURFACE MODIFIERS Russian patent published in 2012 - IPC D04H1/00 A61F13/56 B32B7/00 

FIELD: textile, paper.

SUBSTANCE: system (90) for fastening a nonwoven fabric (10) includes a canvas (12) formed from a variety of extruded threads (14). At least some of the threads (14) in the nonwoven fabric (10) include self-adhesive material. Foamed layer (91) includes a surface (92) having a variety of loosely arranged elements (93). The elements (93) are adapted for engagement with at least a part of the set of threads (14). And at least some of the loosely arranged elements (93) include a surface modifier. The surface modifier is a self-adhesive material, which is similar to self-adhesive material in the nonwoven fabric (10). The threads (14) of non-woven fabric (10) are formed of a multicomponent or bicomponent material. At least one of the materials in multicomponent or bicomponent materials is a self-adhesive material. In one version the absorbent article (95) contains a system of fastening (90) for fixation of the absorbent article (95) on the waistline of the user. In another version, the absorbent article (95) contains a system of fastening (90) for fixation of the absorbent article on the waistline of the user, where the surface modifier comprises a binder or polymer wax. The strength of connection between the non-woven fabric (10) and a part of the foamed layer (91) includes a surface modifier, with a strength of 1.5 times greater than the strength bond between the nonwoven fabric (10) and a part of the foamed layer (91), which does not include a surface modifier.

EFFECT: improved properties of mechanical fasteners and ease of production of fastening system.
