摘要： A full-surface bonded multiple component nonwoven fabric is provided that has an improved combination of tear strength and tensile strength at lower thicknesses than known in the art. The full-surface bonded multiple component webs have a void percent between about 3% and 56% and a Frazier permeability of at least 0.155 m3/min-m2. The full-surface bonded multiple component nonwoven fabrics can be prepared in a smooth-calendering process.

摘要： A moisture vapor permeable, substantially liquid impermeable composite sheet material (16) includes a powder-bonded nonwoven web (22) adhered to a moisture vapor permeable thermoplastic film (12). The nonwoven web (22) includes a first layer (16) comprised primarily of fibers that are compatible with an adhesive used to bond the web, and a second layer (14) comprised of a blend of fibers, some of which are compatible with, and some of which are incompatible with the bonding adhesive and the thermoplastic film. A method for making the composite sheet material (10) and an item of apparel made from the sheet material (10) are also provided.

摘要： A breathable composite sheet material, a method for making such a sheet material, and an absorbent article utilizing the sheet material are provided. The composite sheet material is comprised of a thermoplastic film adhered directly to a fibrous substrate. The thermoplastic film comprises at least 50 % by weight of a polymer material from the group of block copolyether esters, block copolyether amides and polyurethanes. The substrate comprises a fibrous web of at least 50 % by weight of polyolefin polymersynthetic fibers. The composite sheet exhibits a peel strength of at least 0.1 N/cm, a dynamic fluid transmission of less than about 0.75 g/m2 when subjected to an impact energy of about 2400 joules/m2, and a moisture vapor transmission rate, according to the dessiccant method, of at least 1500 g/m2/24hr. The absorbent article comprises: (a) a topsheet; (b) a backsheet; and (c) an absorbent core located between the topsheet and the backsheet; wherein the backsheet comprises the non-porous, substantially fluid impermeable moisture vapor permeable composite sheet material described above. The composite sheet material is oriented such that the film layer of the composite sheet material faces toward the absorbent core. The absorbent article may comprise a disposable diaper.

摘要： Controlled porosity composite sheets comprising a melt-blown polypropylene fiber web (20) having a spunbonded polypropylene fiber sheet (10) laminated to at least one side thereof are made by calendering an assembly of the component webs in such a manner that, when a two-layer composite sheet is made, the web of melt-blown fibers is in contact with a metal roll (1) heated to 140-170 °C operating against an unheated resilient roll (2) and, when a three-layer composite sheet is made, the spunbonded web in contact with the heated metal roll has a dtex per fiber value of less than 6. These composite sheets have a Gurley-Hill porosity of about 5-75 seconds, excellent mechanical and tear strengths, high water vapor penetration rate, and low liquid water permeability. They are particularly suitable for making housewrap sheets and sheets for sterile packaging. In the sterile packaging field, they are significantly better than medical paper used for the same purpose.
