Abstract
A disposable absorbent pad such as a diaper, sanitary napkin, underpad, surgical dressing or wipe, and the like, is made from a flexible, body fluid-impermeable backing sheet, a layer of absorbent material on the backing sheet, and a soft, body fluid-permeable facing sheet which overlies the absorbent material. The facing sheet is a non-woven, open but interconnected network of oriented thermoplastic polymer fiber elements having a mean denier of not more than 3. In addition to being useful as a separate entity, the absorbent pad of this invention can also be incorporated into a disposable or limited use garment as an integral part thereof.
Claims18
An absorbent pad comprising a flexible, body fluid-impermeable backing sheet, a layer of absorbent material on said backing sheet, and a soft, body fluid-permeable facing sheet overlying said absorbent material;
- said facing sheet being non-woven, open but interconnected network of molecularly oriented, thermoplastic polymer fiber elements having a mean denier of not greater than 3;
- said facing sheet having a bulk density of about 0.05 grams/cubic centimeter to about 0.15 grams/cubic centimeter, said fiber elements exhibiting a birefringence greater than 0.005 and being molecularly oriented substantially in the plane of the facing sheet.
A disposable garment including, as an integral part thereof, an absorbent pad comprising a flexible, body fluid-impermeable backing sheet, a layer of absorbent material on said backing sheet, and a soft, body fluid-permeable facing sheet overlying said absorbent material;
- said facing sheet being a non-woven, open but interconnected network of molecularly oriented, thermoplastic fiber elements having a mean denier of not greater than about 3;
- said fiber elements being molecularly oriented substantially in the plane of the facing sheet.
