Abstract

A disposable surgical gown is provided. The gown includes a front panel and sleeves formed from a first spunbond layer, a nonwoven (e.g., SMS) laminate, and a liquid impervious, moisture vapor breathable elastic film disposed therebetween. The gown also includes a first and second rear panels formed from a nonwoven laminate that is air breathable and allows for an air volumetric flow rate ranging from about 20 standard cubic feet per minute (scfm) to about 80 scfm. The gown further includes a collar formed from an air breathable knit material positioned adjacent a proximal end of the gown. The collar defines a neck opening having a v-neck shape adjacent the front panel. The v-neck shape forms an angle of greater than 90° at the neck opening. The combination of features results in a reduced-glare gown that is stretchable and impervious to liquids, yet can still dissipate heat and humidity.

Claims (18)

1. A laminate material comprising:

a liquid impervious, moisture vapor breathable elastic film positioned between a first material and a second material,

wherein the first material comprises a nonwoven layer and the second material comprises a spunbond-meltblown-spunbond laminate,

wherein the elastic film, first material, and second material each include a carbon black pigment and titanium dioxide, wherein carbon black pigment and titanium dioxide are included in at least one spunbond layer of the second material,

wherein the elastic film further includes a fluorochemical additive,

wherein the first material and the second material further include a slip additive, and

wherein the laminate material exhibits an opacity of greater than about 98% and a light transmittance of less than about 0.1.

2. The laminate material of claim 1 , wherein the elastic film further includes a calcium carbonate filler, wherein the calcium carbonate filler is present in a core layer of the elastic film in an amount ranging from about 0.1 wt. % to about 5 wt. % based on the total weight of the core layer.

3. The laminate material of claim 1 , wherein the fluorochemical additive is present in a core layer of the elastic film in an amount ranging from about 50 wt. % to about 85 wt. % based on the total weight of the core layer.

4. The laminate material of claim 1 , wherein the slip additive comprises erucamide, oleamide, stearamide, behenamide, oleyl palmitamide, stearyl erucamide, ethylene bis-oleamide, N,N′-Ethylene Bis(Stearamide) (EBS), or a combination thereof, wherein the slip additive is present in the first material in an amount ranging from about 0.25 wt. % to about 6 wt. % based on the total weight of the first material, further wherein the slip additive is present in the second material in an amount ranging from about 0.25 wt. % to about 6 wt. % based on the total weight of each spunbond layer in the second material.

5. The laminate material of claim 1 , wherein the first material includes a spunbond layer.

6. The laminate material of claim 1 , wherein the first material and each spunbond layer in the second material comprise a copolymer of propylene and ethylene, wherein the ethylene is present in an amount ranging from about 1 wt. % to about 20 wt. %.

7. The laminate material of claim 1 , wherein the meltblown layer in the second material comprises polypropylene.

8. The laminate material of claim 1 , wherein the core layer of the elastic film comprises propylene.

9. The laminate material of claim 1 , wherein the elastic film comprises a first skin layer and a second skin layer disposed on opposite sides of the core layer, wherein the first skin layer and the second skin layer each comprise a copolymer of propylene and ethylene, wherein the ethylene is present in an amount ranging from about 1 wt. % to about 20 wt. %.

10. The laminate material of claim 1 , wherein the elastic film has a basis weight ranging from about 5 gsm to about 50 gsm.

11. The laminate material of claim 1 , wherein the nonwoven layer has a basis weight ranging from about 5 gsm to about 50 gsm and the spunbond-meltblown-spunbond laminate has a basis weight ranging from about 10 gsm to about 60 gsm.

12. The laminate material of claim 1 , wherein the elastic film meets the requirements of ASTM-1671.
