が阻害されてしまう。By making an absorbent product using superabsorbents, it is possible to significantly reduce the bulk of the absorbent product. However, attempts to utilize superabsorbents in absorbent products such as diapers and sanitary napkins have so far been successful only to a limited extent. "Fixing" or sticking superabsorbents into absorbent products is quite difficult. U.S. Pat.No. 3,971,37
No. 9 discloses an absorbent product in which a layer of superabsorbent material is folded or wrapped with another absorbent structure. Second, superabsorbents absorb and retain hundreds of times their own weight in liquid, but have the disadvantage that the liquid does not readily penetrate into it. In an absorbent product, when the superabsorbent absorbs the liquid and swells rapidly without having the ability to permeate the liquid into it, the liquid itself forms a "block" and the rest or absorption of the superabsorbent Utilization of other absorbent materials in the product for absorption purposes is impeded.

超吸収材を吸収製品に利用する新規な方法は超吸収材を

るより改良された繊維構造体が記載されている。New methods of utilizing superabsorbents in absorbent products have focused on incorporating the superabsorbent into the fibrous structure to avoid the "block" problem described above. U.S. Pat. No. 4,105,033 shows a method for incorporating superabsorbents into fibrous structures. U.S. Pat. No. 4,226,237 also describes a more improved fibrous structure of absorbent fibers and peat moss capable of dispersing superabsorbent material.

この層のまわりに折り曲げられている。The present invention uses a novel approach for utilizing superabsorbents in absorbent products. Rather than an attempt to obtain a novel fibrous structure in which the superabsorbent is dispersed to prevent the formation of "blocks", the present invention is capable of producing "blocks" when used alone. Known fiber materials can be used, including some superabsorbents. In the absorbent product of the present invention, the superabsorbent may be dispersed in the fibrous structure or foam or may be present alone or with other components in the film. According to the invention, internal permeation means are provided in the absorbent product to select the liquid up to the superabsorbent. The permeation means surrounds or is folded around a plurality of individual layers containing superabsorbent material.

る超吸収材まで単に移送するだけである。As schematically illustrated in FIG. 1, one embodiment of the absorbent article of the present invention, generally designated by the reference numeral 10, includes at least two separate layers 12 intermixed with a superabsorbent material. In addition, the absorbent product includes an S-shaped permeation means 14 wrapped around and between the superabsorbent layers. The present invention does not relate to the shape or configuration of the superabsorbent layer, and various materials containing the superabsorbent can be used. For example, the superabsorbent layer can be composed of superabsorbent mixed in the fiber layer or the foam layer. The method of incorporating the superabsorbent material into the fibrous layer or foam is not critical. This is because the liquid does not need to penetrate the super absorbent layer, and the surface of the super absorbent layer only needs to absorb the liquid. In fact, according to the invention, the superabsorbent layer can consist of a film formed wholly or partly of the superabsorbent. In the absorbent product of the present invention, the internal permeation means of the absorbent product carries the liquid to the superabsorbent material, so that there is no need for the superabsorbent layer to permeate or transport the liquid. Therefore, swelling of the superabsorbent material within the superabsorbent layer does not prevent the superabsorbent material from impeding the movement of liquid within the absorbent product. When the superabsorbent swells or saturates somewhere in the absorbent product, the internal permeation means simply transfers the liquid to be absorbed to the adjacent still absorbent superabsorbent.

26 and an internal permeation means 24 including a liquid transfer means 28. The permeation layer 26 may be made of any material as long as it has a property of permeating a liquid. It is not necessary for this material to have good absorption capacity or the ability to hold a liquid under stress. Suitable materials for use as the permeation layer are "Orlon" (TM) fabric, pulp tissue material or peat moss. Liquid transfer means can be provided between the permeation layer and at least the major surface of the superabsorbent layer. In the embodiments described above, the tissue layer of Henkel fabric acts as a liquid transfer means. The liquid transfer means 28 transfers the liquid from the permeation layer to the super absorbent layer. The use of a liquid transfer means in the middle serves to keep the internal permeation means, i.e. the flow path, open at all times, while the permeation layer is held while the liquid transfer means holds the liquid in order to allow the superabsorbent layer to absorb the liquid.
