摘要:
There is provided a fibrous web which includes a binder and which is compressed to a density of up to about 0.3 g/cc. The web may preferably be formed by the bonded carded web process or air lay process. The binder may depend on hydrogen bonding using moisture or may be a non-aqueous solution, a powder, a fibrous binder or a conjugate fiber binder including a moisture triggerable component. Conjugate fibers may be crimped. When wetted the web of this invention should expand rapidly to greater than 80 % of its uncompressed thickness and greater than 90 % of its thickness when saturated if starting from the uncompressed state.

There is provided a corrugated nonwoven web where at least 40 percent of the web surface area is made from fusible fibers. The corrugated web is bonded such that no gaps are present between the folds of the web. Such webs provide comparable compression resistance and resiliency to, and greater void volume than, webs having a conventional X-Y plane fiber alignment. There is further provided personal care products having the corrugated nonwoven web as a component where the web is placed in the product in the transverse direction.

The present invention relates to an absorbent article for absorbing fluids and exudates, such as urine. More particularly, the present invention relates to absorbent garments which are configured to absorb body exudates while also helping to reduce the relative humidity in the environment of the article, to reduce skin-exudate contact and to reduced undesired skin hydration. The present invention relates to an absorbent article having a front waist section, a rear waist section, and an intermediate section which interconnects said front and rear waist sections. One embodiment of the absorbent article generally includes: a topsheet having a body-facing surface; a backsheet; an absorbent; and a resilient material positioned between topsheet and the backsheet. The resilient material creates at least one contour which promotes movement of fluid away from one region of the article to another region of the article. The contour of the resilient material desirably creates a hill-like structure.

There is provided a new nonwoven surge material for personal care products made of fibers, which is a nonwoven fabric made of a homogeneous blend of large and small denier fibers. The small or first denier fiber preferably has an average denier less than 2, is at least 3 denier less than the second or larger fiber and the large or second denier fiber has an average denier between 4 and 15. The first denier fiber may have a denier less than 1 and the second denier fiber may have a denier between 6 and 15. The nonwoven fabric is a mixture of these fibers in amounts of from 25 to 75 weight percent of each type of fiber. The fabric may have a basis weight between 30 and 200 gsm. The first denier fiber may be a bicomponent fiber which may be a sheath/core polyethylene/ polypropylene bicomponent fiber. The second denier fiber may be made from a polyester. It is also possible that the fibers have a hydrophilic treatment added to their surface to increase their hydrophilicity. The material made from the homogeneous blend of mixed denier fibers may be used as a liner or as a surge material in personal care products like diapers, training pants, incontinence products, bandages, and sanitary napkins.

There is provided an intake system material for personal care products made from a nonwoven web and having a hydrophobic top surface and a capillary tension gradient which increases in the Z-direction perpendicular to the top surface. The intake system material may be made from a single layer or multiple layers and useful in personal care products like diapers, training pants, incontinence garments and feminine hygiene products.
