Abstract
A feminine guard product capable of absorbing urine applied to said product in relatively small amounts at a relatively low velocity or in relatively large amounts at a relatively high velocity and menses. The feminine guard comprises an outer shell which defines a basin having a volume, an absorbent structure present in said basin, an acquisition layer comprising hydrophilic fibers and present in said basin, and a body side liner having a passage volume of 40 percent and being attached to the outer shell and covering the basin.
Claims11
An absorbent product, said product comprising:
- (a.) a fluid-impervious, flexible outer shell having a length of from about 4 to about 12 inches, a width of from about 1.3 to about 7 inches, and a depth of from about 0.25 to about 2.5 inches, said shell defining a basin having a length, width, volume, and a rim;
- (b) a fluid-pervious body side liner attached to said shell at said rim, said liner having a passage volume of 40 percent;
- (c) a fibrous absorbent structure present in said shell and filling from about 10 to about 95 volume percent of said volume of said basin;
- (d) an acquisition layer present in said basin and located between said liner and said absorbent structure, said acquisition layer comprising a fibrous web of dry resilient fibers, at least about 30 weight percent of said fibers possessing a water-in-air contact angle of less than about 45 degrees, said acquisition layer filling from about 5 to about 50 volume percent of said volume of said basin;
- and
- wherein said acquisition layer can be desorbed by said absorbent structure and said fibers of said acquisition layer are rayon fibers.
An absorbent product, said product comprising:
- (a) a fluid-impervious, flexible polymeric foam outer shell having a length of from about 4 to about 12 inches, a width of from about 1.3 to about 7 inches, and a depth of from about 0.25 to about 2.5 inches, said shell defining a basin having a length, width, volume, and a rim;
- (b) a fluid-pervious body side liner attached to said shell at said rim, said liner having a passage volume of 40 percent;
- (c) a fibrous absorbent structure present in said shell and filling from about 10 to about 95 volume percent of said volume of said basin;
- (d) an acquisition layer present in said basin and located between and in fluid communication with said liner and said absorbent structure, said acquisition layer comprising a fibrous web of dry resilient rayon fibers possessing a water-in-air contact angle of less than about 45 degrees, said rayon fibers being bonded together at certain fiber-fiber intersections and having a fineness of from about 2 denier to about 15 denier, and filling from about 5 to about 30 volume percent of said volume of said basin;
- and
- wherein said acquisition layer can be desorbed by said absorbent structure.
