    Abstract: A plurality of vertically spaced-apart microsprings are provided to increase microspring contact force, contact area, contact reliability, and contact yield. The microspring material is deposited, either as a single layer or as a composite of multiple sub layers, to have a tailored stress differential along its cross-section. A lower microspring may be made to push up against an upper microspring to provide increased contact force, or push down against a substrate to ensure release during manufacture. The microsprings may be provided with similar stress differentials or opposite stress differentials to obtain desired microspring profiles and functionality. Microsprings may also be physically connected at their distal ends for increased contact force. The microsprings may be formed of electrically conductive material or coated with electrically conductive material for probe card and similar applications.

The topsheet, the backsheet, and the absorbent core form a layered assembly including a front region, a back region, and a crotch region disposed between the front region and the back region. The garment is characterized by a vertical longitudinal plane that extends substantially centrally through the front, back and crotch regions. Each of the front and back regions includes a pair of ear portions extending in substantially opposite lateral directions with respect to the longitudinal plane. Each ear portion is a breathable stretchable layer assembly having a plurality of vent sites. Further, each ear portion includes an outer layer that is an extension of the backsheet and which extends laterally to the side edge of the ear portion, and an inner layer that is an extension of the topsheet and which also extends laterally to the side edge of the ear portion.

  • Patent number: 6974514
    Abstract: A method is disclosed for the production of an air-permeable laminate film with a textile surface and elastic and non-elastic regions. At least one film strip that is elastic in the crosswise direction is introduced, as an elastic insert, between two material webs of fiber non-woven fabric having a web width greater than the width of the film strip. The segments of the material webs made of fiber non-woven fabric that are in direct contact next to the insert are connected, forming a non-elastic region of the laminate film. Subsequently, the laminate passes through an ultrasound bonding station, in which the elastic insert is melted by means of point-shaped bonds, while maintaining the substance of the fiber non-woven fabric, thereby connecting the elastic insert with the fiber non-woven fabric cover layers at discrete points and forming air-permeable structures.

  • Patent number: 6969441
    Abstract: In the invention, a method is provided for producing a composite nonwoven fabric. A polymer is extruded into heated continuous filaments, possibly elastic, from the die head to a first chilled roller, wherein the extruder is configured to provide the continuous filaments to the chilled roller in a canted direction that is at a tangent or angle to the surface of the first chilled roller. The filaments are conveyed in a downward direction by way of chilled rollers to a nip. In a next step, the nonwoven web is sprayed with an adhesive and is laminated on the continuous filaments in the nip to form a composite nonwoven fabric. The continuous filaments move vertically downward approximately in line with the lamination process, facilitating automatic re-threading of filaments when they are broken or interrupted in their travel downward onto the chilled rolls.

  • Patent number: 6964720
    Abstract: An elastomeric nonwoven laminate and a process for producing the elastomeric nonwoven laminate are proved. The elastomeric nonwoven laminate includes a first nonwoven, a second nonwoven and a plurality of elastic strands. The plurality of elastic strands is attached to the first nonwoven while under a strain producing a corrugated intermediate laminate once the strain is relieved. A second nonwoven is joined to the corrugated intermediate laminate and subsequently mechanically activated forming an elastomeric nonwoven laminate.

  • Patent number: 6951591
    Abstract: Laminates of thermoplastic films and nonwoven fibrous webs are made at high speeds on the order of about 700 fpm to about 1200 fpm. Bond strengths of film and nonwoven laminates are effectively controlled to make breathable laminates at high speeds. Air cooling devices cause the air to flow substantially parallel to the extruded plastic web during drawdown and provide a plurality of cooling air vortices to effectively cool the web. Film gauge control is also achieved by the method.

  • Patent number: 6942748
    Abstract: An elastomeric film is bonded between two or more layers of nonwoven webs formed of nonelastomeric thermoplastic fibers. The laminate has, in a predefined transverse direction, an elastic elongation value greater than the predefined elastic elongation value of the nonwoven webs, and an ultimate force to break in the predefined transverse direction of at least 3000 g/in. The laminate advantageously provides a tear resistant, multiple ply, fabric that is soft to the touch as a result of the outwardly disposed nonwoven webs, and has a high elastic modulus. The laminate is particularly useful in applications where closure portions of a product must be stretched to keep the product in place when worn.

  • Patent number: 6884310
    Abstract: The present invention provides a method of achieving selectively elasticized zones on nonwoven web substrates, such as may be suitable for the waistbands of disposable absorbent pant garments, cuffs on sleeves of medical garments, or the like. A web, or webs, of nonwoven material which make up the substrate for the elasticized area are provided to be inherently extendable in the transverse, or lateral, direction of the material web at the time the elastic material is affixed to the substrate. If the elastic material is affixed in an untensioned state, a flat waistband without gathering of the substrate may be had for a very efficient seal against the skin of the wearer. If the elastic material is affixed to the substrate in a tensioned state, a waist band with gathering of the substrate may be had to allow for two-stage expansion via the gathers and the expansion of the substrate.
