摘要： The present invention is directed to a pattern-unbonded nonwoven fabric having continuous bonded areas defining a plurality of discrete unbonded areas, which is suitable for use as an improved loop fastening material for hook and loop fastening systems. The fibers or filaments within the discrete unbonded areas of the present invention are dimensionally stabilized by the continuous bonded areas that encircle or surround each unbonded area. The spaces between fibers or filaments within the unbonded areas remain sufficiently open or large to receive and engage hook elements of a complementary hook material. The hook material can be any of a wide variety of commercially available hook components which, as is known in the art, typically include a base material from which a plurality of hook elements project. The present invention further is directed to a process for making such a pattern-unbonded nonwoven fabric including the steps of providing a nonwoven fabric or web, providing opposedly positioned first and second calender rolls and defining a nip therebetween, with at least one of said rolls being heated and having a bonding pattern on its outermost surface comprising a continuous pattern of land areas defining a plurality of discrete openings, apertures or holes, and passing the nonwoven fabric or web within the nip formed by said rolls.

摘要： A method is provided for producing fine denier multicomponent thermoplastic polymer filaments incorporating high melt-flow rate polymers. Multicomponent filaments are extruded such that the high melt-flow rate polymer component is substantially surrounded by one or more low melt-flow rate polymer components. The extruded multicomponent filament is then melt-attenuated with a significant drawing force to reduce the filament diameter and form continuous, fine denier filaments.

摘要： Absorbent nonwoven web composites exhibit a combination of excellent strength, softness and absorbency. The composites utilize a combination of substantially continuous bicomponent thermoplastic filaments, and pulp fibers. The substantially continuous bicomponent filaments distribute liquid insults and contribute durability and softness. The pulp fibers and, optionally, a superabsorbent, absorb and contain the liquid.

摘要： There is provided an absorbent material for personal care products which is made from wettable fibers of at most 40 microns in diameter which are made into a web and where the web has controlled spaces in the side away from a wearer point unbonded bonding pattern. The web will accept a liquid insult of 50 ml with a runover/run-through percentage ratio of less than 1.5. Such a web material may be used in personal care products like diapers, training pants, absorbent underpants, adult incontinence products and feminine hygiene products. Especially of interest are diapers having a narrow crotch, i.e., those having a crotch width of at most 7.6 cm.

摘要： Multicomponent fiber nonwoven webs having excellent liquid handling and/or repellency properties are described wherein the multicomponent thermoplastic polymer fibers have exposed first and second components that form the outer surface of the multicomponent fibers and that extend substantially continuously along the length of the fibers. The first component comprises a thermoplastic polymer and an active agent, such as a liquid repellency agent, and the second component comprises a thermoplastic polymer and contains from 100% to 50% by weight less active agent than the first component.

摘要： High loft, low density nonwoven webs are produced by forming substantially continuous, spunbond, crimped, bicomponent fibers of A/B side by side morphology in an unheated fiber draw unit. The fibers are then heated and cooled in the absence of impeding forces to achieve maximum crimp in the z-direction and produce a web of loftedmaterial. The resultant material is particularly suitable for use as an insulator. Particulates may be added to the webs if desired.
