The presently disclosed subject matter relates to a multilayer nonwoven material. More particularly, the presently disclosed subject matter relates to multilayered structures including, but not limited to, two, three, or four layers to form the nonwoven material. The multilayered structure can include a first layer comprising continuous filaments and a second layer comprising bonded fibers. The continuous filaments can be synthetic filaments. The fibers can be cellulosic fibers, noncellulosic fibers, or combinations thereof. Certain layers can also contain a binder material.

Multistrata nonwoven material

A disposable surgical gown (100) is provided. The gown includes a front panel (102) and sleeves (104) 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 (120, 122) 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 (110) 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 gown that is stretchable and impervious to liquids, yet can still dissipate heat and humidity.

Disposable surgical gown

A film composition comprising from 5 to 75 percent by weight of an ethylene/α-olefm interpolymer composition (LLDPE), and from 25 to 95 percent by weight of a propylene/α-olefin interpolymer composition, and films made from the film composition, wherein the films exhibited synergistic physical properties, namely holding force and elastic recovery, are provided.

Bimodal polypropylene compositions and a process to form melt blended bimodal polypropylene compositions comprising combining at least two polypropylenes in at least a two-pass process, and forming a bimodal polypropylene composition having a Flexural Modulus (190°C, 1% secant) of at least 1700 MPa, as well as one or more other selected properties. These compositions are suitable for thermoformed articles and injection molded articles, any of which may be foamed.

This invention relates to polypropylene fibers and fabrics containing polypropylene fibers, the fibers comprising propylene polymers comprising at least 50 mol % propylene, said polymers having: a) a melt flow rate (MFR, ASTM 1238, 230° C., 2.16 kg) of about 10 dg/min to about 25 dg/min; b) a dimensionless Stress Ratio/Loss Tangent Index R2 [defined by Eq. (8)] at 190° C. from about 1.5 to about 30; c) an onset temperature of crystallization under flow, Tc,rheol, (as determined by SAOS rheology, 190° C., 1° C./min, where said polymer has 0 wt % nucleating agent present), of at least about 123° C.; d) an average meso run length determined by 13C NMR of at least about 55 or higher; and e) optionally, a loss tangent, tan δ, [defined by Eq. (2)] at an angular frequency of 0.1 rad/s at 190° C. from about 14 to about 70.
