Abstract

This disclosure describes a multi-layer liquid absorption and distribution nonwoven fabric for hygiene products, which has a topside facing the user in hygiene products and an underside facing the absorbent core in hygiene products, the fiber blend of the nonwoven fabric forming the underside having a lower average fiber titer than the fiber blend of the nonwoven fabric forming the topside. The bond between the topside and the underside is purely thermal. The topside consists of a fiber blend of 50 to 100% by weight of melting fibers with 50 to 0% by weight of matrix fibers. The underside consists of a blend of 50 to 80% by weight of absorbent fibers with 50 to 20% by weight of melting fibers.

Claims12

Dependent claims

A multilayer liquid absorption and distribution nonwoven fabric for hygiene products, the nonwoven fabric comprising:

a topside facing a user in hygiene products and an underside facing the absorbent body in hygiene products, wherein:
a fiber blend of the nonwoven fabric forming the underside has a lower average fiber titer than a fiber blend of the nonwoven fabric forming the topside,
the topside consists of a non-woven fabric, and the fiber blend of the topside consists of 50 to 100% by weight of melting fibers and 50 to 0% by weight of matrix fibers,
the underside consists of a non-woven fabric, and the fiber blend of the underside consists of 50 to 80% by weight of absorbent fibers and from 50 to 20% by weight of melting fibers,
the topside is exclusively thermally fusion-bonded to the underside, and
the density of the nonwoven fabric is 35 kg/m3 or less.
