20080200890 | ANTIMICROBIAL DISPOSABLE ABSORBENT ARTICLES - Disposable absorbent articles comprising an absorbent material and a degradable thermoplastic polymer composition comprising an aliphatic polyester and an antimicrobial composition. The antimicrobial composition includes an antimicrobial component and an enhancer component. The aliphatic polyester and antimicrobial composition are formed into webs by melt extrusion, such as nonwovens and films, that are incorporated into disposable absorbent articles, such as disposable infant diapers, adult incontinence articles, feminine hygiene articles such as sanitary napkins, panty liners and tampons, personal care wipes and household wipes to provide odor control, control of microbial growth, and control of microbial toxin production. | 08-21-2008 |
20100080841 | FIBROUS ARTICLES WITH ONE OR MORE POLYELECTROLYTE LAYERS THEREON AND METHODS FOR MAKING THE SAME - Fibrous articles having fibers coated with one or more polyelectrolyte layers are disclosed. Methods of making and using the fibrous articles are also disclosed. | 04-01-2010 |
20100197027 | AN INDICATING FIBER - A fiber, an articles formed from a fiber and methods of making the fiber and associate article are disclosed. In one embodiment, the fiber comprises a synthetic polymer and a color-changing indicator. The color-changing indicator is dispersed throughout the synthetic polymer. The color-changing indicator reacts in the presence of a stimulus to produce a color change. | 08-05-2010 |
20110151737 | DIMENSIONALLY STABLE NONWOVEN FIBROUS WEBS AND METHODS OF MAKING AND USING THE SAME - Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing. | 06-23-2011 |
20110151738 | DIMENSIONALLY STABLE NONWOVEN FIBROUS WEBS, MELT BLOWN FINE FIBERS, AND METHODS OF MAKING AND USING THE SAME - Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. In some embodiments, the fibers comprise a viscosity modifier and/or an anionic surfactant. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing. | 06-23-2011 |
20110189463 | MELT BLOWN FINE FIBERS AND METHODS OF MANUFACTURE - Fine fibers comprising aliphatic polyester and a viscosity modifier. The fine fibers are preferably made by a Blown microfiber process. | 08-04-2011 |
20120315225 | DIMENSIONALLY STABLE NONWOVEN FIBROUS WEBS AND METHODS OF MAKING AND USING THE SAME - Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. Antishrinkage and antistatic additives are also added to the fibrous webs. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing. | 12-13-2012 |
20130190408 | BIOCOMPATIBLE HYDROPHILIC COMPOSITIONS - Durable hydrophilic compositions comprising aliphatic polyester, an anionic surfactant, and in some embodiments, a carrier. | 07-25-2013 |
20130288556 | DIMENSIONALLY STABLE NONWOVEN FIBROUS WEBS, AND METHODS OF MAKING AND USING THE SAME - Dimensionally stable nonwoven fibrous webs include a plurality of fibers formed from one or more thermoplastic polyesters and an antishrink additive, preferably in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 12% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. The webs may be used as wipes. | 10-31-2013 |
20140210141 | PROCESS OF MAKING DIMENSIONALLY STABLE NONWOVEN FIBROUS WEBS - Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. In some embodiments, the fibers comprise a viscosity modifier and/or an anionic surfactant. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing. | 07-31-2014 |
20150075125 | FILTER FRAME ASSEMBLY WITH SEAL - A filter frame assembly is disclosed comprising a perimeter member surrounding a fluid aperture adapted to accommodate a fluid flow from an upstream direction to a downstream direction, the perimeter member comprising a perimeter upstream surface, a perimeter downstream surface, and a perimeter outer surface connecting the perimeter upstream surface to the perimeter downstream surface. A gasket carrier is attached to the perimeter member and comprises a carrier outer portion facing generally away from the fluid aperture and a first outer portion sealing member projecting from the carrier outer portion. | 03-19-2015 |
