Disposable surgical gown
11576449 · 2023-02-14 · ·

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.

A protective garment is constructed with a fibrous material. The fibrous material comprises a first nonwoven layer, a second nonwoven layer, and a nanofiber layer laminated between the first nonwoven layer and the second nonwoven layer. The fibrous material has a mean flow pore size greater than or equal to about 0.02 micron and less than or equal to about 0.5 microns, and a water vapor transmission rate greater than or equal to about 10000 g/m.sup.2/day and less than or equal to about 100000 g/m.sup.2/day. In a method of making a fibrous layer, a first nonwoven layer and a nanofiber layer are provided. A polyurethane reactive resin is applied to the first nonwoven layer in an amount of 2 to 30 g/m.sup.2. The nanofiber layer is then laminated to the first nonwoven layer applied with the polyurethane reactive resin and pressed to form the fibrous layer.

20220408985 · 2022-12-29 ·

A cleansing wipe may be formed from a nonwoven and includes a first ethylene/alpha-olefin interpolymer and a second ethylene/alpha-olefin interpolymer. The cleansing wipe may also have a SaMbSc configuration, wherein the M, meltblown layer, is formed from the first ethylene/alpha-olefin interpolymer and the second ethylene/alpha-olefin interpolymer. The cleansing wipe may be formed a nonwoven comprising bicomponent fibers that incorporate the first ethylene/alpha-olefin interpolymer and the second ethylene/alpha-olefin interpolymer.

Personal protection and ventilation system

A personal protection and ventilation system is provided. The system includes a gown having front and rear panels, a hood, and visor; a fan; an air tube; and a helmet. The fan is positioned between the wearer and a body-facing surface of the rear panel. The front panel and at least a portion of the hood are formed from a first material including a first spunbond layer, a spunbond-meltblown-spunbond laminate, and a liquid impervious elastic film disposed therebetween. The first material has an air volumetric flow rate of less than about 1 standard cubic feet per minute (scfm). The rear panel is formed from a second material including a nonwoven laminate having an air volumetric flow rate of about 20 scfm to about 80 scfm. Therefore, the fan is able to intake a sufficient amount of air from the environment through the rear panel to provide cooling/ventilation to the hood.

Textile Backsheet

Textile backsheets including a nonwoven fabric and film, such as a vapor-permeable and liquid impermeable (VPLI) film or a non-permeable film, are provided, wherein the nonwoven fabric is directly or indirectly bonded to the film. Methods of making such textile backsheets and absorbent articles including the textile backsheets are also provided.

SOUND CONTROL FABRICS, MATS, SYSTEMS, AND METHODS

A fabric composite for a gypsum underlayment sound control mat includes a first layer including a spunbond polyolefin layer, a second layer including a nonwoven polyolefin layer, and a hot-melt adhesive layer between and bonding the first layer and the second layer. A gypsum underlayment sound control mat may include the fabric composite bonded to an entangled mesh layer.
