Abstract RU 2723286 C1

FIELD: manufacturing technology.

SUBSTANCE: according to the present invention, stretching sheet (1) for an absorbent article is disclosed, in which a plurality of elastic filaments (4), which are arranged so that they pass in one direction, without crossing themselves with each other, are connected to extensible sheet materials (2 and 3) on their entire length in substantially not stretched state. Some or all of the plurality of elastic filaments (4) are narrow filaments (40) having at least one narrow portion (40k) in a cross-section which is orthogonal to the longitudinal direction (Y). It is preferable that the cross-section of each filament (40) with narrowing, which is orthogonal to the longitudinal direction (Y), has a shape, in which a plurality of circles are connected together in a partially overlapping state, and preferably, the distance between centers of adjacent circles is less than sum of radius of first of circles and radius of second of circles, and more, than shorter radius from radius of first circle and radius of second circle.

EFFECT: stretching sheet for the absorbent product is disclosed.
