  • Publication number: 20070000020
    Abstract: An elastomeric article having a mechanically or chemo-mechanically modified surface for improved anti-slip-down protection, and certain methods for producing the article are disclosed. The methods involve applying a colloidal particle-containing slurry or an abrasive-impregnated substrate to the an exposed elastomeric matrix surface to create a rough, textured or scabrous surface with a topography of micron-scale ridges and dimples.

  • Publication number: 20060218697
    Abstract: An elastomeric article encompassing an enclosure with an interior surface having at least two regions or zones is described. The first region has a higher coefficient of friction than the second region, in which an average coefficient of friction (COF) ratio between the first and second regions of the wearer-contact surface ranges from about 1:1.2 to about 1:3.8 or 4.0. The first region has either the same or smaller surface area than the second region, and is situated at or near an opening to the enclosure. The second region is coated with a hydrogel-based donning layer. A process of making the elastomeric article is also provided. Examples of elastomeric articles according to the invention include surgeons' gloves that exhibit good lubricity and donning characteristics, and have an improved cuff-slippage control.

  • Publication number: 20030135182
    Abstract: The present invention relates to absorbent articles. Specifically, the present invention relates to a personal care article having improved performance. The present invention is directed to personal care articles, including feminine pads, having a multi-component liquid absorbent structure that provides maximum protection, reduces leakage and generally stays dry to the touch, provides a better fit, and, after an insult, is more aesthetically pleasing because it masks or hides more liquid. The absorbent articles include a multi-component liquid absorbent structure that has a first liquid absorbent component that is a coherent, flexible matrix including stratified layers of fibrous material as well as a second liquid absorbent component.

  • Patent number: 5464688
    Abstract: There is disclosed a nonwoven web for use as a barrier layer in an SMS fabric laminate. The web is formed at commercially acceptable polymer melt throughputs (greater than 3 PIH) by using a reactor granule polyolefin, preferably polypropylene, that has been modified by the addition of peroxide in amounts ranging from up to 3000 ppm to reduce the molecular weight distribution from an initial molecular weight distribution of from 4.0 to 4.5 Mw/Mn to a range of from 2.2 to 3.5 Mw/Mn. Also the addition of peroxide increases the melt flow rate (lowers viscosity) to a range between 800 up to 5000 gms/10 min at 230.degree. C. The resulting web has an average fiber size of from 1 to 3 microns and pore sizes distributed predominantly in the range from 7 to 12 microns, with a lesser amount of pores from 12 to 25 microns, with virtually no pores greater than 25 microns, and with the peak of the pore size distribution less than 10 microns.

  • Patent number: 5447788
    Abstract: A porous, nonwoven liquid-activated barrier which includes a fibrous nonwoven web in which at least about 50 percent by weight of the fibers constituting the fibrous nonwoven web are prepared from a liquid-swellable polymer which is not significantly soluble in the liquid. In addition, the fibers of the fibrous nonwoven web have diameters in a range of from about 0.1 to about 100 micrometers. The pores of the fibrous nonwoven web have a longest dimension in a range of from about 0.3 to about 300 micrometers. In the presence of liquid, the fibers swell to an extent sufficient to substantially block the passage of liquid through the fibrous nonwoven web. In many instances, the liquid will be water.

  • Patent number: 4778460
    Abstract: A multilayer nonwoven fabric is disclosed which comprises at least two layers of nonwoven web. Each nonwoven web comprises a plurality of monofilaments of a thermoplastic material. In at least one of the webs the monofilaments have a bilobal cross-section. Preferably, the fabric includes two layers of nonwoven web with the monofilaments of the first web having the bilobal cross-section and the monofilaments of the second web having a trilobal or branched cross-section.

  • Patent number: 4753834
    Abstract: Nonwoven webs are disclosed which comprise monofilaments or fibers of a thermoplastic material. Basically, the improvement comprises the use of monofilaments or fibers which have a bilobal shaped cross-section. Nonwoven webs made according to this invention are particularly suited to be used for liners for disposable diapers as well as wraps for catamenial devices. Methods are also disclosed for producing such nonwoven webs.

  • Patent number: 4318407
    Abstract: A tampon having a pledget consisting of two rectangular layers of absorbent material which have been overlaid along an edge of each of the layers and then folded along a line bisecting the angle formed by the juncture between the layers. The pledget thus produced has both inner and outer absorptive layers and a containment pocket formed of absorptive material in the fold area.

  • Patent number: 4296750
    Abstract: In disposable diapers which are equipped with tape closure means and have an impermeable thin film backing, the improvement in which selected areas of the thin film, which areas serve as tape securement zones when the diapers are in use, have uniformly adhered to that side of the film facing the diaper interior a layer of hot melt adhesive to provide a composite structure in the selected areas having a high resistance to tearing when tensile loads are applied. The hot melt adhesive layer has a lower modulus of elasticity than the film and is applied in heat-softened condition to obtain strong, uniform adherence to the film. In a method for applying the adhesive layer, a wide band of adhesive of predetermined thickness is extruded in heat-softened condition into direct contact with selected areas of a moving web of the film. The adhesive is one which has a Ring & Ball softening point lower than the heat distortion temperature of the film and during application will not thermally degrade or distort the film.

  • Patent number: 4050462
    Abstract: A disposable, single-use, generally elongate diaper having substantially planar sections at each end and intermediate these planar ends a substantially non-planar section comprising the crotch section. The crotch section is narrower than at least one of the ends and is longitudinally constricted by elastically extendible means secured to each of the edges of the crotch section in a manner which produces a plurality of gross transverse rugosities across the width of the crotch section of the diaper when the elastic means is in non-extended condition. The width dimension of the crotch is preferably within a predetermined percentage range of the combined width of the planar waist sections. The length dimension of the narrower crotch section is preferably a specified percentage of the full unconstricted length of the diaper. A further improvement is obtained if the geometry of the side edges between the wide waist section and the narrower crotch section is defined by a concave arc.
