Abstract
Provided is a composite sheet material having a first layer and an airlaid nonwoven layer overlying the first layer wherein the airlaid nonwoven layer includes a blend of bamboo derived staple fibers and non-cellulose staple fibers, and in which the airlaid nonwoven layer includes a first surface disposed towards, and thermally bonded, to a surface of the first layer, and a second surface defining an outer surface of the composite sheet material.
Claims23
A composite sheet material comprising:
- a first layer;
- and
- an airlaid nonwoven layer overlying the first layer, the airlaid nonwoven layer comprising a blend of bamboo derived staple fibers and non-cellulose staple fibers, the airlaid nonwoven layer comprising a first surface disposed towards, and thermally bonded, to a surface of the first layer, and a second surface defining an outer surface of the composite sheet material.
An absorbent core for an absorbent article, the core comprising an airlaid layer comprising bamboo derived staple fibers.
A method of making a composite sheet comprising:
- providing a first layer of a sheet material;
- depositing a first airlaid layer onto a surface of the first layer to form a composite sheet, the first airlaid layer comprising a mixture of bamboo derived staple fibers and non-cellulose staple fibers;
- and
- air through bonding the composite sheet with heated gas to cause a polymer of the non- cellulose staple fibers to melt and fuse with adjacent fibers, wherein non-cellulose staple fibers of the air laid layer are bonded to each other, the bamboo derived staple fibers, and the first layer.
