The present invention generally relates to absorbent sanitary articles for absorption of body fluids and in particular to a sanitary article of this type including a buffer composition adapted to adjust the natural pH of the absorbed body fluid to a pH that is compatible with the pH of skin.

Absorbent article including a buffer composition

A process for manufacturing robust, flexible sheet-like material, includes the steps of a) applying a waxy composition to the web to form a waxed web; b) leading the waxed web via at least one roller to a chiller; c) cooling the waxed web; and d) leading the waxed web to a collection station for collecting the waxed web for further processing. The waxy composition comprises about 10-60 wt-% of a waxy compound and about 90-40 wt-% of a diluent. The waxy compound is selected from the group consisting of A) monoesters of a polyhydric aliphatic alcohol and a fatty acid; B) diesters of a polyhydric aliphatic alcohol and a fatty acid; and C) mixtures of said monoesters and diesters. The coating forms a stable liquid mixture at a temperature between about 35&#xb0; C. and about 100&#xb0; C., has a liquefaction temperature of at least about 30&#xb0; C., and has a contact angle with a flat surface of the substrate of less than about 35&#xb0; when measured at a temperature of 60&#xb0; C.

A foaming porous pad suitable for coupling to a hand-held device and for application to human skin includes a porous pad substrate and a foaming composition disposed on the porous pad substrate. The porous pad substrate includes a nonwoven pile fabric having a nonwoven backing layer and a pile comprising individual fibers extending from the backing layer. The nonwoven pile fabric has fibers having a denier of less than about 9. Other aspects of the disclosure include a kit including a foaming porous pad and a motorized handheld device, methods of making the foaming porous pad, and methods of using the foaming porous pad.

A sanitary napkin including a body facing surface, a portion adapted to be arranged over the vaginal opening during use, a first colored portion, said colored portion extending over at least the portion of the napkin to be placed over the vaginal opening during use, a noncolored portion, wherein said first colored portion has a first color as measured from said body facing surface prior to staining, wherein the first colored portion has a second color as measured from said body facing surface after staining, wherein the first color has an average L value greater than 80; and wherein a &#x394;a* between said first color and said second color is less than 18.

Absorbent article having stain resistant properties

The invention provides an apertured web comprising multiple, discrete zones comprising arrangements of land areas and at least two apertures.

A tampon, particularly for feminine hygiene, includes an absorbent body and a variably perforated or apertured cover. The absorbent body has an introduction end, a withdrawal end, and a longitudinal main portion therebetween. The cover includes a fluid-impervious plastic material in the form of a resilient three-dimensional web having a multiplicity of perforations. The perforations are varied over the length of the tampon so that a differentiated expansion of the tampon while absorbing fluid is achievable. Preferably, the degree of perforations of the cover increases towards the withdrawal end of the tampon at least over a portion of its length.

Melt blown die apparatus are provided for producing a fibrous web from a polymer material. The apparatus includes a die and a primary gas assembly for providing a pressurized gas at the exit end of the die. The primary gas assembly includes a tubular chamber for receiving and distributing the pressurized gas along the first dimension of the die. The tubular chamber includes a pressure control diverter for providing a substantially even gas pressure distribution across the first dimension of the die. This apparatus can be operated at exit air flow rates of up to about 200 pounds of air per pound of polymer at a polymer flow rate of about 4.0 pounds per linear die inch per minute. Constructions are provided for minimizing bending moments and for providing thermal and structural stability to the apparatus.
