Bonding fiber for airlaid multi-layer products and process for production of said airlaid multi-layer products

Abstract

A bonding fiber and a process using this fiber have been developed to produce airlaid multi-layer structures with sufficient bonding within each layer and between layers including bonding to unwound carrier sheets using a bonding fiber which will remain in the intended layer of the airlaid multi-layer structure. Further the bonding fiber will not be lost through low basis weight unwound carrier and top sheets. A bonding fiber for airlaid, multilayer products comprising a thermoplastic material selected from the group comprising nanofibers, micro-fibers, and 0.5 to 30 dTex staple fibers and having a length between 0.3 mm to 70 mm.

What is claimed is: 
     
         1 . A bonding fiber for airlaid, multilayer products comprising a thermoplastic material selected from the group comprising nanofibers, micro-fibers, and 0.5 to 30 dTex staple fibers and having a length between 0.3 mm to 70 mm.
