Abstract
Abstract A surface material for sanitary articles is composed of Layer 1, which is located on the surface in contact with the skin, and Layer 2, which is formed into a single unit with Layer 1 underneath Layer 1 with its entire surface being essentially covered by Layer 1, and with Layer 1 being composed of 50% or more hydrophobic fibers and moreover, in which at least the portion of Layer 1 covering Layer 2 possesses Section A of which the fiber density is comparatively low, Section B of which the fiber density is comparatively high, and Section C which is located at their boundary, where the area of Section C occupies 2-50% of the area of the entire surface material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
A surface material for sanitary articles which has the characteristic of being composed of Layer 1, which is located on the surface in contact with the skin, and Layer 2, which is formed into a single unit with Layer 1 underneath Layer 1 with its entire surface being essentially covered by Layer 1, and with Layer 1 being composed of 50% or more hydrophobic fibers and moreover, in which at least the portion of Layer 1 covering Layer 2 possesses Section A of which the fiber density is comparatively low, Section B of which the fiber density is comparatively high, and Section C which is located at their boundary, where the area of Section C occupies 2-50% of the area of the entire surface material.
Claim 2
Dependent Claim
125 words
A surface material for sanitary articles which has the characteristic of being composed of Layer 1, which is located on the surface in contact with the skin, and Layer 2, which is formed into a single unit with Layer 1 underneath Layer 1 with its entire surface being essentially covered by Layer 1, and with Layer 1 being composed of 50% or more hydrophobic fibers and moreover, in which at least the portion of Layer 1 covering Layer 2 possesses Section A of which the fiber density is comparatively low, Section B of which the fiber density is comparatively high, and Section C which is located at their boundary, where the area of Section C occupies 2-50% of the area of the entire surface material.
Claim 3
Dependent Claim
86 words
A preparing method of a surface material for sanitary articles which has the characteristic of passing Layer 1, which is located on the surface in contact with the skin and is composed of a fiber aggregate of 50% or more hydrophobic fibers, and Layer 2 located beneath layer 1, which is composed of a fiber aggregate of 50% or more hydrophilic fibers, through an engraving roll in the form of a laminated structure followed by partial compression bonding and/or fusing to give it an embossed pattern.
Claim 4
Dependent Claim
86 words
A preparing method of a surface material for sanitary articles which has the characteristic of passing Layer 1, which is located on the surface in contact with the skin and is composed of a fiber aggregate of 50% or more hydrophobic fibers, and Layer 2 located beneath layer 1, which is composed of a fiber aggregate of 50% or more hydrophilic fibers, through an engraving roll in the form of a laminated structure followed by partial compression bonding and/or fusing to give it an embossed pattern.
Claim 5
Dependent Claim
57 words
A preparing method of a surface material for sanitary articles as described in Claim 2 which is a fiber aggregate in which Layer 1 is formed into a web using a carding machine from fibers of which the main component is heat-fusing short fiber, and which is prepared by fusing with a heating roll or heating fluid.
Claim 6
Dependent Claim
57 words
A preparing method of a surface material for sanitary articles as described in Claim 2 which is a fiber aggregate in which Layer 2 is formed into a web using a carding machine from fibers of which the main component is heat-fusing short fiber, and which is prepared by fusing with a heating roll or heating fluid.
Claim 7
Dependent Claim
79 words
A preparing method of a surface material for sanitary articles as described in Claim 3 in which an embossed pattern is formed by compression bonding and/or fusing which possesses Section A, which has comparatively low fiber density, Section B, which has comparatively high fiber density, and Section C, which is at the boundary of Sections A and B, such that the surface area ratio of Section C is 2-50% with respect to the total surface area of the embossing.
Claim 8
Dependent Claim
96 words
A preparing method of a surface material for sanitary articles as described in Claim 2 in which with respect to the direction of flow of the fiber aggregate, the web of Layer 2 is suctioned and removed at fixed intervals with respect to the horizontal direction prior to lamination of Layer 1 and Layer 2, and following lamination, the central portion of the portion that is essentially Layer 1 only is slit and wound so that Layer 2 does not exist at a fixed width on both ends in the horizontal direction of the sanitary article.
