Claims (10)

1. The structure for absorption consists of a membrane made of flexible fibrous silotomies. This membrane has a base weight of less than approximately 4 oz/sq yard (0.0136 g/cm²), an initial dry material content of at least approximately 20 cm³/g, a dry material recovery of at least approximately 30 percent, and a wet material content of at least approximately 30 cm³/g. The superior absorbent material is distributed among the fibers of the membrane in an amount of at least approximately 200 percent by weight relative to the weight of the membrane. The structure has a taber stiffness of less than approximately 50. 2. The aspiration structure of claim 1, which has a Taber hardness value approximately 25 less than that mentioned. 3. The absorption structure of claim 1 shall incorporate a layer of pulp fibers on at least one side of the aforementioned absorption structure. 4. The product of patent clause 3, which adds layers of pulp fibers to both sides of the aforementioned absorption structure. 5. The structure for the absorption of claim 1, whereby the aforementioned fiber bonding sheet is a polyester fiber bonding sheet. 6. Disposable diapers with an absorbent layer constructed from a composite fiber membrane containing at least approximately 20 cm³/g of initial dry material, at least 30% of recoverable dry material, and at least 30 cm³/g of wet material. Furthermore, a special absorbent material is distributed between the fibers of the composite membrane in an amount of at least approximately 200% by weight compared to the weight of the composite membrane. The structure has a Taber stiffness of less than approximately 50. 7. Sanitary pads have an absorbent structure consisting of a membrane of interwoven fibers with a base weight of less than approximately 4 oz/m² (0.0136 g/cm²), a starting material of at least approximately 20 cm³/g, a total dry material recovery of at least approximately 30 percent, and a total wet material recovery of at least approximately 30 cm³/g. A special absorbent material is distributed between the fibers of the aforementioned membrane in an amount of at least approximately approximately 200 percent by weight of the weight of the interwoven membrane. This structure has a minimum Taber stiffness of approximately 50. 8. A process for producing an absorbent structure capable of absorbing at least approximately 5 cm³/g of liquid and being a non-woven interlocking sheet with a base weight of less than approximately 4 oz/sq (0.0136 g/cm²), with an initial dry material of at least approximately 20 cm³/g, a total dry material recoverability of at least approximately 30 percent, and a total wet material of at least approximately 30 cm³/g, and with a special absorbent material distribution of approximately 200 percent by weight. The process consists of (a) drying the interlocking sheet containing the aforementioned special absorbent material until its moisture content is less than approximately 25 percent, and (b) finely wrinkling the interlocking sheet to achieve a TABER stiffness of less than approximately 50. 9. The procedure for claim 8, where the aforementioned Taber hardness is less than approximately 25. 10. The procedure for claim 8 in which the Taber hardness mentioned is less than approximately 10 in at least one direction (Clause 10, page 2, figure x).
