Publication number: 20080070465Abstract: The invention relates to a high loft nonwoven composite comprising a nonwoven layer having a first and second side and a thermoplastic layer. The nonwoven layer comprises about 60 to 90% by weight of a high crimp polyester fiber having between about 5 and 20 crimps per inch and about 10 to 40% by weight of a core/sheath polyester fiber, where the sheath has a lower melting temperature than the core. The nonwoven layer is calendared on at least the first side. A thermoplastic layer is applied to the first side of the nonwoven layer.Type: ApplicationFiled: September 18, 2006Publication date: March 20, 2008Inventor: Thomas Cobbett Wiles

Patent number: 7341963Abstract: A non-woven material including first effect fibers, first binder fibers, second binder fibers, and bulking fibers. The non-woven material has a first planar zone with an exterior skin, and a bulking zone. The first planar zone includes a greater concentration of first effect fibers and first binder fibers. The bulking zone includes a greater concentration of bulking fibers and second binder fibers. The first effect fibers can be fire retardant fibers.Type: GrantFiled: May 17, 2005Date of Patent: March 11, 2008Assignee: Milliken & CompanyInventors: David E. Wenstrup, Gregory J. Thompson

Publication number: 20070287348Abstract: An outer cover for use with an absorbent article having a layer of nonwoven fibrous material and optionally including a polymeric layer laminated or printed onto the layer of nonwoven fibrous material. The outer cover includes at least one plastic component and at least one elastic component in the nonwoven fibrous material and/or optional polymeric layer. The outer cover can have different structural combinations of spunbond fibers, meltblown fibers, and/or nanofibers. The combination of plastic and elastic components results in an outer cover that has favorable mechanical, physical, and aesthetic properties. The outer cover can be rendered either uniaxially or biaxially stretchable via a mechanical activation process.Type: ApplicationFiled: November 15, 2006Publication date: December 13, 2007Inventors: Jean-Philippe Marie Autran, Donald Carroll Roe, Terrill Alan Young, Joan Helen Mooney, Fred Naval Desai

Publication number: 20070283493Abstract: The present invention relates to a flame-retardant removable cover which may be applied to a mattress. The removable cover, when applied to mattress, may reduce the peak heat release rate and/or total energy released in accordance with 16 CFR 1633 testing protocols. The cover may comprise a non-woven material. The removable cover may also comprise a non-woven type construction and an elastomeric material. The removable cover may therefore be designed with respect to the different requirements of those mattresses to which it may be applied to assist in meeting open flame mattress flammability standards.Type: ApplicationFiled: June 7, 2007Publication date: December 13, 2007Applicant: Freudenberg Nonwovens Limited PartnershipInventors: Eberhard Link, James Frasch, Ashutosh P.

Publication number: 20070275180Abstract: A unitary, fiber-containing composite comprises (a) a first region comprising a plurality of first binder fibers and a plurality of bast fibers, (b) a second region disposed above the first region, the second region comprising a plurality of second binder fibers and a plurality of bast fibers, and (c) a transitional region disposed between the first region and the second region. The transitional region comprises concentrations of the first binder fiber, the second binder fiber, and the bast fiber. The concentration of the first binder fiber in the first transitional region is greatest proximate to the first region and least proximate to the second region, and the concentration of the second binder fiber and the bast fiber in the first transitional region is greatest proximate to the second region and least proximate to the first region. A method for producing a unitary, fiber-containing composite is also described.Type: ApplicationFiled: May 26, 2006Publication date: November 29, 2007Inventors: Gregory J.

Publication number: 20070270070Abstract: A method for making stiffened cellulosic fiber in sheet form, and the resultant stiffened cellulosic fiber. The method of making the stiffened fibers involves impregnating a cellulosic base fiber in sheet form with a treatment composition solution, drying and curing the impregnated sheet, and thereafter adding water or an aqueous solution of odor removing agent to the cured sheet to produce a sheet of stiffened cellulosic fiber having a moisture content of at least about 6.0 weight %. When defiberized, the stiffened fiber has a low content of fines and knots and nits. The stiffened fiber also exhibits a low degree of yellowing and is substantially free of a burnt-like odor. The stiffened fiber may be used in an absorbent article, such as in a liquid acquisition layer or absorbent core of a baby diaper.Type: ApplicationFiled: May 19, 2006Publication date: November 22, 2007Inventor: Othman A.
