Appl. No.:

09/301492

International Classification:

A61F 1315

US Classification:

60438501, 604367

Abstract:

There is provided a personal care product having a vapor sweep comprising a material which reacts with water or urine to form vapor at a rate capable of displacing at least 5, and preferably at least 10, percent of the air volume within said product per minute. This vapor generation sweeps water vapor and humidity from the personal care product, such as a diaper, and so its believed will contribute to skin health. Materials that, upon reaction with water or urine, produce large volumes of carbon dioxide may be incorporated into the various components of standard personal care products to achieve the objective of this invention. Such materials include leavening agents. Additionally, a seal may be added to the personal care product to encourage the generated vapor to travel a longer path prior to exiting the product in order to maximize water vapor removal.

Abstract:

An absorbent pad has a cover formed of non-woven fibrous material, which is coated with a fluorocarbon polymer and odor absorber(s). The cover sheet is apertured around a critical zone to overcome undesired surface tension effects. The method of producing the cover includes providing a water-based mixture that includes 1% by weight of a fluorocarbon composition. An odor absorbing reagent is added to the mixture which then is applied to a nonwoven web of fibrous material. The treated web is dried to remove the excess water from the mixture, and the fluorocarbon composition component is cured to form a hydrophobic coating around the reagent and to bind the reagent to the web. The drying and curing steps can be accomplished by applying a flow of air heated to a temperature in a range from about 100. degree. C. to about 120. degree. C. to the web until the water has been removed.

Abstract:

Disclosed is an odor-absorbing, non-dusting porous web material and a method of making the same. The web material includes a porous base web (for example, a fibrous base web, such as a non-woven or paper web) having distributed throughout odor-absorbing particulate (such as zeolite). Alkaline salt or alkaline earth oxide particulate, to better effect removal of acidic malodor, desirably also is distributed throughout the base web, in the final product. The odor-absorbing particulate is bound to the base web (e. g. , fibers of a fibrous base web) by a binding system, containing a binding agent. The binding system, in the odor-absorbing web materials, is transparent to the odors so as not to substantially effect the ability of the particulate to absorb odor-causing material. The odor-absorbing web material is formed by dipping a porous base web in a saturant slurry containing the odor-absorbing particulate (the slurry including an alkaline salt or alkaline earth oxide) and the binding agent, together with a surfactant; squeezing out excess saturant slurry from the web; and drying. Also disclosed are two specific uses of the odor-absorbing web material: (1) in personal care products such as catamenial devices; and (2) in packages containing medical materials such as hospital gowns, which materials have been sterilized in the sealed package by gamma sterilization.
