A method is disclosed for producing a polyurethane film including the steps of depositing a prepolymer composition, drying the prepolymer composition, and crosslinking the propolymer composition.

Polyurethane synthesis

Microporous structures in face films are described for improving printability of the films. Also described are laminates and pressure sensitive adhesive laminates including the microporous structured face films. Various related methods are additionally described.

Face films and pressure sensitive laminates for printing

An absorbent article of the present invention may comprise a topsheet, an outer cover, and an absorbent core disposed therebetween. The outer cover may comprise an extrusion bonded laminate. The EBL may comprise a multi-layer coextruded elastomeric film and a nonwoven. The film may comprise a core layer, a first outer layer, and a second outer layer, wherein the core layer is between the first and second outer layers. The nonwoven may comprise fibers and/or filaments. The first outer layer may be non-adhesively joined to the nonwoven via extrusion coating. Further, the outer cover may be elastic to at least about 50% engineering strain. The nonwoven may have high chemical affinity for the first outer layer. The first outer layer may have a low chemical affinity for the core layer; and the multi-layer coextruded elastomeric film may have a basis weight no greater than about 40 gsm.

Extrusion bonded laminates for absorbent articles

An absorbent article of the present invention may comprise a topsheet, an outer cover, and an absorbent core disposed therebetween. The outer cover may comprise an extrusion bonded laminate. The EBL may comprise a multi-layer coextruded elastomeric film and a nonwoven. The film may comprise a core layer, a first outer layer, and a second outer layer, wherein the core layer is between the first and second outer layers. The nonwoven may comprise fibers and/or filaments. The first outer layer may be non-adhesively joined to the nonwoven via extrusion coating. Further, the outer cover may be elastic to at least about 50% engineering strain. The nonwoven may have high chemical affinity for the first outer layer. The first outer layer may have a low chemical affinity for the core layer. And, the first outer layer may comprise an amount of draw down polymer greater than about 45 wt %.

Some embodiments of the present invention include elastomeric films with a basis weight of about 40 gsm or less or about 25 gsm or less. Other embodiments include elastomeric laminates comprising the elastomeric film bonded to one or more substrates (such as nonwoven fabrics). Methods of making the elastomeric films and elastomeric laminates are also provided.

Elastomeric materials

Some embodiments of the present invention include elastomeric films with a basis weight of about 40 gsm or less or about 25 gsm or less. Other embodiments include elastomeric laminates comprising the elastomeric film bonded to one or more substrates (such as nonwoven fabrics). Methods of the making the elastomeric films and elastomeric laminates are also provided.

Absorbent articles in which the outer cover has an extrusion bonded laminate.

Moisture-resistant materials comprise an open net-like fabric with strands of varying thicknesses and polymer film thereon. The material is both resistant to water penetration and also slip resistant under dry or wet conditions. The moisture-resistant materials are suitable for use in various applications including roofing underpayment, flashing, housewrap and other construction sheet-like materials. An optional second layer of fabric may be applied to the moisture-resistant material, for example, to improve the strength, tear resistance, and scuff resistance of the moisture-resistant material.
