    摘要： A hydrophilic melt-extruded multicomponent polymeric strand including a first melt-extrudable polymeric component and a second melt-extrudable, hydrophilic polymeric component, the first and second components being arranged in substantially distinct zones across the cross-section of the multicomponent strand and extending continuously along the length of the multicomponent strand, the second component constituting at least a portion of the peripheral surface of the multicomponent strand continuously along the length of the multicomponent strand. The second component renders the strand hydrophilic and preferably has a critical surface tension at 20.degree. C. greater than about 55 dyne/cc, and more preferably greater than about 65 dyne/cc. A suitable hydrophilic second component comprises a block copolymer of nylon 6 and polyethylene oxide diamine. Suitable polymers for the first component include linear polycondensates and crystalline polyolefins such as polypropylene. Nonwoven fabrics and absorbent articles made with the hydrophilic multicomponent polymeric strands are also disclosed.

    摘要： There is disclosed an nonwoven fabric suitable for use as, for example, an intake/distribution material for personal care products, made from nonwoven fabric where the fabric is made from directly formed, mixed size fibers. The fibers may be conjugate fibers. The fabric may have zones having larger fibers and zones having smaller fibers providing a means to vary the web properties, such as permeability, or the mixed size fibers may be uniformly distributed. The fibers may also be crimped. The process for making such a material is also disclosed.A zoned fiber fabric can provide rapid intake of an insult because of the placement of the high permeability zone in the insult target area and can also provide good distribution through the lower permeability but higher capillarity end zones.

    摘要： A durable, single or multi-use cooling garment is provided having a multilayer structure. The cooling garment includes an inner layer of a thermoplastic polymer material that is liquid impermeable and vapor permeable, an outer liquid permeable reinforcing layer such as a web of thermoplastic polymer fibers, and a central absorbent layer that contains a stabilized matrix of about 55% to 95% cellulosic fibers and from about 5% to 45% thermoplastic polymer fibers. The layers are bonded together and the absorbent layer is bonded to at least one of the other layers by regionally applying sufficient energy to the layers wherein the thermoplastic polymers melt and resolidify to form inter-fiber bonds. The cooling garment can be saturated with water or other liquids and provide the wearer with relief from the heat such as may be achieved by evaporative cooling.
