Abstract

DC60 (16/06/42) Top sheet for body fluid absorbent material with numerous 6 pores allowing fluid to flow through. The top sheet consists of a relatively low-density top fiber layer and a relatively high-density bottom fiber layer around each 6 pore. The first and second fiber layers 11,12 are combined with the top sheet 2 to have a gradual increase in density from the top surface to the bottom surface of top sheet 2, and the bottom surface has a higher density than the second fiber layer 12. The fabricated top sheet is modified so that the top surface can remain dry during use of the material with 2 top sheets. Top sheet for body fluid absorbent material with numerous 6 pores allowing fluid to flow through. The top sheet consists of a relatively low-density top fiber layer and a relatively high-density bottom fiber layer around each 6 pore. The first fiber layer The second layer, 11,12, was incorporated with a gradual increase in density between the top and bottom surfaces of the top layer 2, with the bottom surface having a higher density than the second fiber layer 12. The fabricated top layer was modified so that its surface could remain dry during use with objects featuring top layer 2.

Claims (8)

1. The top layer for the liquid-absorbing material consists of: the top layer with a surface oriented to contact the wearer's skin; a bottom surface located beneath the top surface; more than one permeable pore protruding between the top and bottom surfaces; the top layer with an upper portion defined by the first fiber layer and a lower portion defined by a second, denser fiber layer than that of the first fiber layer; and around each pore, the first and second fiber layers are combined so that the density of the top layer increases progressively from the top surface to the bottom surface, exceeding the density of the second fiber layer. 2. The top layer as per claim 1, whereby the underside of the first fibrous layer and the overside of the second fibrous layer are periodically bonded together by thermal melt bonding. 3. The top layer as per claim 1, whereby both the first and second fibrous layers are hydrophilic, and the second fibrous layer has a higher hydrophilicity than that of the first fibrous layer. 4. The top layer pursuant to claim 1, where the first fiber layer is hydrophobic and the second fiber layer is hydrophilic. 5. The top layer pursuant to claim 1, where at least one of the first and second fibrous layers is constructed from a non-woven fabric. 6. The top layer under Claim 1, whereby the first fiber network has a base weight of 10-30 g/m² and the second fiber network has a base weight of 10-100 g/m² and a corresponding density of at least 1.3 times that of the first fiber network. 7. The top layer for the liquid-absorbing material consists of: a top surface oriented for contact with the wearer's skin; a bottom surface located beneath the top surface; more than one permeable pore protruding between the top and bottom surfaces without extending beyond the bottom surface; this top layer having an upper portion defined by the first fiber layer and a lower portion defined by a second, denser fiber layer than that of the first fiber layer, where the entire bottom surface of the first fiber layer is in close contact with the top surface of the second fiber layer; and around each such pore, the first and second fiber layers are combined so that the density of the top layer increases gradually from the top surface towards the bottom surface, and at least in the region near the bottom surface, it is denser than in the second fiber layer. 8. The top layer for the liquid-absorbing material must consist of: such a top layer with a surface oriented to contact the wearer's skin; a bottom surface located beneath the top layer; more than one permeable pore protruding between the top and bottom surfaces; such a top layer with an upper portion defined by the first fiber layer and a lower portion defined by a second, denser fiber layer than that of the first fiber layer; and around each such pore, the first and second fiber layers are combined in such a way that the density of the top layer increases gradually from the top surface towards the bottom surface, and at least near the bottom surface, the density increases even more than that of the second fiber layer.
