Abstract: The present invention provides an efficient method for topically treating and drying fibrous web materials such as nonwoven web materials and nonwoven laminate materials without unduly damaging the materials due to excessive heating during drying.

Abstract: The present invention provides continuous fiber nonwoven webs with high material formation uniformity and MD-to-CD balance of fiber directionality and material properties, as measured by a MD:CD tensile ratio of 1.2 or less, and desirably of about 1.0 or less, and laminates of the nonwoven webs. The invention also includes a method for forming the nonwoven webs wherein the fiber production apparatus is oriented at an angle less than 90 degrees to the MD direction and the fibers are subjected to deflection by a deflector oriented at an angle B with respect to the centerline of the fiber production apparatus where B is about 10 to about 80 degrees.

Abstract: Disclosed herein is a method for making fibrous web materials which may be used in or as absorbent core materials for absorbent products. The method involves providing loose fibers, entraining the fibers in a moving airstream, treating the fibers with an energy-activatable pre-polymer composition and subjecting the fibers to activation energy to initiate cross-linking of the composition. The fibers are collected on forming surface to form a fibrous web. The fibers may be treated with the composition while entrained in the moving air or after being collected on the forming surface, or in an alternate embodiment by treating with the composition a mat of fibers from which the loose fibers are provided. The fibrous web material may comprise cellulosic fibers such as pulp, and/or synthetic fibers such as staple fibers, and/or super absorbent materials.

Abstract: A container liner, shelf liner or drawer liner that will absorb liquids spilled or leaked into a container or onto a shelf or drawer. The liner is a layered product having a layer which is impervious to liquids and an absorbent layer. The absorbent layer further contains a material which is capable of controlling odors, such as those odors found in refrigerators and waste receptacles. The liner of the present invention provides the benefit of absorbing spills and controlling odors in containers such as refrigerators and waste receptacles.

Abstract: The present invention provides a multicomponent fiber containing at least two polymer components arranged in distinct zones or segments across the cross-section of the fiber wherein at least one component of the fiber contains a thermoplastic polymer and at least one component of the fiber contains a thermoset polymer. The invention also provides fabrics and fabric laminates containing the multicomponent fibers, and articles containing the fabric. Additionally provided is a process for producing the multicomponent fibers.

Abstract: A porous polymeric sheet is provided having an electrostatic charge and comprising a zero-three composite of a polymeric matrix and a ferroelectric material dispersed therein. The polymeric component comprises a non-polar thermoplastic polymer, such as a polyolefin, and a second thermoplastic polymer having polar functional units, such as a telomer. The composite material is formed into a porous sheet and is electrically or corona poled to create an electret material which is well suited four use in various filtration, air-masking and dust wipe applications.

Abstract: A process of forming a nonwoven fabric is disclosed which comprises the steps of forming a precursor web of multicomponent substantially continuous filaments, exposing the precursor web to a hydraulic arrangement treatment to form apertures without causing substantial filament entanglement, and thereafter forming inter-filament bonds and an integrated web. The resulting apertured nonwoven fabrics have good hand and tactile aesthetics and have a great variety of uses including use in absorbent personal care products, garments, medical applications, and cleaning applications.

Abstract: The present invention provides multicomponent fine fiber webs and multilayer laminates thereof having an average fiber diameter less than about 7 micrometers and comprising a first olefin polymer component and a second distinct polymer component such as an amorphous polyolefin or polyamide.
