The second layer can include cellulose material, spunbond, nonwoven fabric, and a thermal bond, nonwoven fabric. Attachment of the first layer of material to the at least one second layer of material can occur through thermobonding, e.g., heated gas, infrared heat and heated calender rolls. The application of adhesives and the use of ultrasonic energy can also bond the layers together. Approximately five percent (5%) to fifty percent (50%) of the first component can be selectively melted for superior airflow.Type: GrantFiled: October 15, 2004Date of Patent: October 3, 2006Assignee: BHA GroupInventors: Alan Smithies, William C. Zimmerman

Patent number: 7115535Abstract: The present invention relates to a substantially dry, disposable personal care article comprising: a) a water insoluble substrate comprising: 1) a non-scouring, lofty, low-density batting layer comprising synthetic fibers; and 2) a non-lofty, fluid-permeable nonwoven layer which is disposed adjacent to said batting layer; and b) a cleansing component disposed adjacent to said batting layer, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a lathering surfactant. The present invention further relates to a substantially dry, disposable personal care article suitable for conditioning wherein the above-described article comprises a therapeutic benefit component, disposed adjacent to said water insoluble substrate, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a therapeutic benefit component in addition to or in lieu of the cleansing component.Type: GrantFiled: November 19, 1999Date of Patent: October 3, 2006Assignee: The Procter & Gamble CompanyInventors: Edward Dewey Smith, III, Karen Joanne Wassell, Marc Paul Lorenzi

Patent number: 7094270Abstract: The invention refers to a composite filter for filtering a stream of ambient air including at least one non-prebonded upstream tier and one non-prebonded downstream tier, wherein the ratio of absolute pore volume of upstream tier to downstream tier RAPV>2, and the absolute projected fiber coverage of upstream tier and of downstream tier APFC>95%. Further, the invention refers to a method of making such a composite filter including the steps of (a) laying down a filtration material onto a support to form the upstream non-prebonded tier, (b) depositing onto the upstream tier the downstream non-prebonded tier, and (c) bonding the tiers to form a composite filter having a unitary stratified structure.Type: GrantFiled: March 1, 2002Date of Patent: August 22, 2006Assignee: Airflo Europe N.V.Inventors: Jan Schultink, Bas Schultink

Patent number: 7070884Abstract: The present invention is directed to a nonwoven composite fabric for use on batteries or fuel cells comprising one or more layers of fine denier spunbond filaments and at least one layer of barrier material, wherein said nonwoven composite fabric has an improved barrier performance as measured by an increase in the hydrostatic head to barrier layer basis weight ratio. In the present invention, a first fine denier layer is formed, comprising continuous spunbond thermoplastic filaments, with the size of the continuous filaments between about 0.7 and 1.2 denier, preferably less than or equal to 1 denier. A barrier layer is deposited onto the first fine denier layer. The barrier layer preferentially comprises microfibers of finite length, wherein the average fiber diameter is in the range of about 1 micron to about 10 microns, and preferably between about 1 micron and 5 microns, said layers being consolidated into a composite fabric.Type: GrantFiled: October 8, 2002Date of Patent: July 4, 2006Assignee: Polymer Group, Inc.Inventors: Julia A. Thompson, Richard Ferencz, Nick Mark Carter

Patent number: 7063917Abstract: A nonwoven material having a laminated construction and including a first layer of nonwoven fibers defining a first surface of the material; a second layer of nonwoven fibers defining the opposite surface of the material; and a third layer of nonwoven fibers located between the first and second layers. The layers are bonded together to form a laminate. At least one of the nonwoven layers comprises a nonwoven web of meltblown fibers. Additionally, one or more of the layers has been rendered permanently hydrophilic by forming the nonwoven web from meltspun fibers of a normally hydrophobic polymer having a hydrophilic melt additive incorporated therein.Type: GrantFiled: February 19, 2002Date of Patent: June 20, 2006Assignee: Ahlstrom Mount Holly Springs, LLCInventors: Larry L. Kinn, Clement J. Haley, Gregory N. Henning

Patent number: 7053012Abstract: A cover (200) for inhibiting corrosion of a metallic object over which the cover is placed. The cover has an inner surface (104) defined by a liquid-permeable layer (202) and an outer surface (102) defined by a liquid-impermeable layer (204). A moisture-absorbing layer (206) is sandwiched between the liquid-permeable layer and the liquid-impermeable layer. The liquid-permeable layer allows vapor and liquid moisture beneath the cover to be absorbed into the moisture-absorbing layer to reduce the amount of moisture beneath the cover. The liquid-impermeable layer repels environmental liquid moisture, such as rain, sea spray, dew and the like and prevents such moisture from penetrating the cover. A radar-influencing layer (308) and vapor corrosion inhibitors (214) may be included in the cover. A method of protecting an object is also disclosed. The method includes covering a metallic object with cover (200).Type: GrantFiled: October 21, 2004Date of Patent: May 30, 2006Assignee: Creare Inc.Inventors: Nabil A. Elkouh, Bruce R. Pilvelait
