ABSTRACT:
There is provided and fibrous layer for personal care products wherein the fibrous layer is made from micro-fine fibers deposited as an aqueous slurry onto a nonwoven web, and subsequently dried. The micro-fine fibers have a diameter from a positive amount to 0.5 microns. The nonwoven web may be produced from a number of methods, such as meltblowing, spunbonding, coforming, bonding and carding, and airlaying. The micro-fine fiber layer can be used to adjust the permeability of the nonwoven web, thus providing a method of controlling the rate of fluid movement through a personal care product, like diapers, training pants, incontinence garments and feminine hygiene products.
