摘要： The present invention is directed to a method of forming nonwoven webs comprising coated fibers. The method of forming the nonwoven web generally comprises the steps of forming fibers from a melt fibrillation process, forming at least one fluid stream containing a coating substance, applying the coating substance onto the surface of the fiber, and depositing the coated fibers on a surface to form a web. Typically, the fibers are coated in flight. Preferably, the melt fibrillation process to form the fibers is a melt film fibrillation process. A melt film fibrillation process generally includes the steps of providing a polymeric melt, utilizing a central fluid stream to form an elongated hollow polymeric film tube, and using air to form multiple nanofibers from the hollow tube. The nonwoven web may comprise a layer having a significant number of nanofibers with diameters less than one micron. The layer may comprise two or more pluralities of fiber diameter distributions wherein at least one plurality has an average fiber diameter of less than about one micron. The coating substance can be selected from the group consisting of lotions, powders, surfactants, softeners, nanoparticles, creams, gels, conducting fluids, hydrophilic agents, hydrophobic agents, hygroscopic agents, emollients, plasticizers, absorbent gelling material, antimicrobial agents, and combinations thereof. A preferred coating substance is a surfactant. Another preferred coating substance is a hydrophilic or hydrophobic substance. The present invention is also directed to a nonwoven web comprising a layer having a significant number of nanofibers with diameters less than one micron and a coating substance is applied to a surface of said nanofibers.

摘要： The present invention is directed to hygiene articles comprising nanofibers. The hygiene articles include diapers, training pants, adult incontinence pads, catamenials products such as feminine care pads and pantiliners, tampons, personal cleansing articles, personal care articles, and personal care wipes including baby wipes, facial wipes, body wipes, and feminine wipes. The nanofiber webs can be used as a barrier, wipe, absorbent material, and other uses. Particularly, the nanofiber web is used in a diaper as a barrier-on-core, outercover, and/or leg cuff. It may also be used as a wipe for reducing the gradient of liquid, controlled delivery of materials, and other uses. The nanofibers, having a diameter of less than 1 micron, must comprise a significant number of the fibers in one layer of the web contained by the hygiene article. The nanofibers are produced from a melt film fibrillation process. The process generally includes the steps of providing a polymeric melt, utilizing a central fluid stream to form an elongated hollow polymeric film tube, and using this and/or other fluid streams to form multiple nanofibers from the hollow tube.

摘要： Nonwoven substrates suitable for use as wet wipes are disclosed. The nonwoven substrates comprise at least one first region and at least one second region. The second region comprises reinforced protruding elements. In a preferred embodiment, the second region of the nonwoven substrate is reinforced by means of thermal bonding during the creation of the protruding elements of the second region. A liquid can be added to the nonwoven substrate prior to packaging or prior to use to make wet wipes. The reinforced second regions of the nonwoven substrates of the present invention make it possible to retain thickness of the wipe when wet without increasing the dry basis.
