Claims
- 1. A sanitary article which comprises:
- an absorbent layer,
- a leakproof sheet substantially surrounding said absorbent layer, and
- a surface sheet encasing said absorbent layer and said leakproof sheet,
- whereby said sanitary article consists of hydrophobic, thermoplastic porous fibers fixed on respective surfaces of at least one of said absorbent layer, leakproof sheet and surface sheet, such that said fibers are in direct contact with said respective surfaces.
- 2. The sanitary article of claim 1, wherein said fibers have a thickness of from 1 to 40 .mu.m and a weight of from 3 to 50 g/m.sup.2.
- 3. A method of preparation of an absorbent sanitary article which comprises:
- providing an absorbent material to be used as an absorbent in an absorbent sanitary article, a leakproof sheet of material to be used to substantially surround said absorbent material and a surface sheet of material to ultimately encase said absorbent and leakproof materials,
- fixing to respective surfaces of at least one of said absorbent material, leakproof sheet of material and surface sheet of material by fiber welding a hydrophobic, thermoplastic porous fiber such that said fiber is in direct contact with said respective surfaces,
- and fabricating said absorbent sanitary article by substantially surrounding said absorbent material with said leakproof sheet and thereafter encasing said resulting composite with said surface sheet.
- 4. The method according to claim 3, wherein said thermoplastic fibers are fiber welded to said respective surfaces by melting a thermoplastic resin to form a molten resin, ejecting said molten resin with air at a temperature of from 200.degree. to 400.degree. C., through a nozzle having a plurality of fine openings of 100 .mu.m to 500 .mu.m, onto said respective surface.
- 5. The method according to claim 3, wherein said thermoplastic fibers are fiber welded to said respective surfaces by dissolving a thermoplastic resin in a suitable solvent to form a solution, spraying said solution onto said respective layers to become fixed thereto and drying.
