Perforated films having channels with cutout portions capable of spontaneous fluid inversion

A polymeric film for use in absorbent structures comprises a planar surface having a frontside, a backside and a plurality of apertures. Walls extend from the perimeter of the apertures and outwardly from the backside. The walls and the backside form a capillary system on the backside. The walls form channels which connect the frontside of the film to the capillary system on the backside. The walls have at least one cut out portion extending the length of the walls. A fluid contacting the frontside of the film will spontaneously invert to the capillary system on the backside of the film through the cut out portions of the walls

Grease and moisture absorbing inserts for microwave cooking

A novel insert useful in a microwavable food container comprising a metallized layer of heat susceptor thickness or a plastic layer, having openings which are in a position to be adjacent to food in said container, a layer of absorbent material comprising fibers, and a substrate layer which is stable to microwave heating conditions. The invention also is directed towards other inserts useful in microwavable food containers comprising fibers which are capable of spontaneously transporting water or n-decane on the surface thereof

Fibers capable of spontaneously transporting fluids

Disclosed are fibers that are capable of spontaneously transporting certain fluids, for example aqueous fluids, such as water, on their surfaces. The fibers, especially in the form of tow, can be incorporated into absorbent articles, such as diapers, in order to transport fluids to more effectively utilize the absorbent portion of the article. The fibers can be synthetically coated with absorbent materials

Process of making fibers

Disclosed are fibers that are capable of spontaneously transporting certain fluids, for example aqueous fluids, such as water, on their surfaces. The fibers, especially in the form of tow, can be incorporated into absorbent articles, such as diapers, in order to transport fluids to more effectively utilize the absorbent portion of the article.

Process of making a non-circular cross-sectional fiber

A melt extrusion composition made by combining about 99.9 to about 98.5 weight percent of at least one polyester and about 0.1 to about 1.5 weight percent additive provides for a polyester or copolyester non-circular cross-sectional fiber having at least four percent improved shape retention as compared to the same fiber made from a melt extrusion composition without the additive. The additive is present at the air-polymer interfacial surface during melt spinning. A method of making the fiber is also disclosed

Composite fibrous filters

Disclosed are novel composite fibrous structures which have utility as filters. These composite structures have at least two layers. The first layer is a nonwoven fibrous structure made from uniquely grooved fibers. The second layer is of a fibrous material that offers high filter efficiency.. The first layer has significantly lower pressure drop and higher dust holding capacity than the second layer

Spinneret orifices and filament cross-sections with stabilizing legs therefrom

This invention relates to spinnerets having orifices of unique cross-sections, the spinnerets being useful for extruding therethrough filaments having U and E shaped cross-sections with stabilizing legs. The use of strategically placed stabilizing legs allow the filaments to maintain the desired shape. The U shaped filament cross-section provides improved drainage over previous filament cross-sections

Toy articles of manufacture comprising spontaneously wettable fibers

This invention relates to an article of manufacture consisting of a toy having a plurality of synthetic fibers capable of spontaneously transporting water on the surface thereof, said fibers satisfying the following equation wherein .theta..sub.a is the advancing contact angle of water measured on a flat film made from the same material as the fiber and having the same surface treatment, if any, X is a shape factor of the fiber cross-section that satisfies the following equation ##EQU1## wherein P.sub.w is the wetted perimeter of the fiber and r is the radius of the circumscribed circle circumscribing the fiber cross-section and D is the minor axis dimension across the fiber cross-section

Immunochip analysis identifies multiple susceptibility loci for systemic sclerosis

In this study, 1,833 systemic sclerosis (SSc) cases and 3,466 controls were genotyped with the Immunochip array. Classical alleles, amino acid residues, and SNPs across the human leukocyte antigen (HLA) region were imputed and tested. These analyses resulted in a model composed of six polymorphic amino acid positions and seven SNPs that explained the observed significant associations in the region. In addition, a replication step comprising 4,017 SSc cases and 5,935 controls was carried out for several selected non-HLA variants, reaching a total of 5,850 cases and 9,401 controls of European ancestry. Following this strategy, we identified and validated three SSc risk loci, including DNASE1L3 at 3p14, the SCHIP1-IL12A locus at 3q25, and ATG5 at 6q21, as well as a suggested association of the TREH-DDX6 locus at 11q23. The associations of several previously reported SSc risk loci were validated and further refined, and the observed peak of association in PXK was related to DNASE1L3. Our study has increased the number of known genetic associations with SSc, provided further insight into the pleiotropic effects of shared autoimmune risk factors, and highlighted the power of dense mapping for detecting previously overlooked susceptibility loci
