Claims
- 1. In an absorbent article having an absorbent member, a leakproof layer, and a non-woven fabric layer comprising at least a surface layer, the improvement comprising said non-woven fabric being 40 wt % or more of conjugate fibers, each of said conjugate fibers being made of a first polyester and a second low crystalline polyester, said second low crystalline polyester (1) having a melting temperature of 50.degree. C. or more below the melting temperature of said first polyester, and (2) a height of an endothermic peak of 5% or greater, as measured by Differential Scanning Colorimetry, than that of said first polyester, said conjugate fibers being contained in every layer of said non-woven fabric layer.
- 2. The absorbent article of claim 1 wherein said conjugate fibers are further treated with a surfactant.
- 3. The absorbent article of claim 1 wherein said conjugate fibers are further treated with a substance having a hydrophilic group and is chemically bonded to said conjugate fibers.
- 4. The absorbent article of claim 1 wherein said conjugate fibers are further treated with a chemical substance having a hydrophilic group which is kneaded into said conjugate fibers.
- 5. The absorbent article of claim 1 wherein the thickness of said conjugate fibers is from 1.5 to 10 deniers.
- 6. The absorbent article of claim 1 wherein said second polyester has a melting temperature of at least 100.degree. C. below the melting temperature of said first polyester.
- 7. The absorbent article according to claim 1, wherein said non-woven fabric is heat bonded to said leakproof layer.
- 8. The absorbent article according to claim 1, wherein said conjugate fibers are made hydrophilic by plasma processing.
- 9. The absorbent article according to claim 1, wherein said height of endothermic peak of said second polyester is 20% or greater, as measured by Differential Scanning Colorimetry, than that of said first polyester.
- 10. The absorbent article according to claim 1, wherein said second polyester is a low melting point polyethylene terephthalate.
