摘要:
The present invention is an absorbent structure to be used in absorbent articles, having at least a first region for acquisition/distribution of fluid and a second region for storage of fluid. The first region can contain materials which have a relatively high capillary desorption pressure, as the materials in the second region exhibit a sufficiently high capillary absorption pressure so as to still efficiently drain the first region. The first region material has a Capillary Sorption Desorption Height (CSDH 90) of more than 40 cm and the second region material satisfies at least one of following requirements: (a) an absorption capacity of at least 15 g/g at 35 cm in the capsorption test; (b) an absorption capacity of at least 15 g/g at 0 cm in the capsorption test and an absorption efficiency of at least 55 % at 40 cm; (c) a Capillary Sorption Absorption Height at 50 % of its capacity at 0 cm absorption height (CSAH 50) of at least 35 cm in the capsorption test.
摘要:
When a superabsorbent material is to be incorporated into an absorbent composite in a relatively high concentration, it is necessary to carefully choose the superabsorbent material. Properties of the superabsorbent to be considered are total Absorbent Capacity, resistance to Deformation Under Load, the ability of the superabsorbent material to absorb while under a restraining force, and the ability of the superabsorbent material to wick fluids away from the insult area. By quantifying these characteristics of a superabsorbent material, one is able to predict which superabsorbent materials are suited for use in absorbent composites comprising a relatively high concentration of superabsorbent material.
摘要:
An absorbent article such as a sanitary napkin, having flaps (24) and a recessed area (68) wherein the flaps may be tucked. The recessed area is formed by joining the inward longitudinal edge of the retaining members (78) to the absorbent assembly at a point inboard of the longitudinal edge of the main body portion.
摘要:
An absorbent article having a liquid permeable topsheet (11), a liquid impermeable backsheet (12), an absorbent member (13) interposed between said topsheet and backsheet, and a moisture absorbent material, wherein the amount of moisture absorption per unit area of the absorbent article is not less than 7.2 x 10⁻⁴ g/hr·cm², and a total amount of moisture absorption of the absorbent article is not less than 0.10 g/hr in an environment of 35°C/75%RH.
摘要:
Sanitary napkins and other absorbent products as well as a method for their use are provided by this invention. The sanitary napkin includes wick means (30, 35) disposed on a body-facing side of the napkin which is biased away from the body-facing side to provide a body-contacting portion disposed in a different plane from the plane of the body-facing side.
摘要:
Absorbent laminates, which may be used as or in diapers, incontinence pads, sanitary napkins, tampons or wound dressings, comprise a hydrophilic layer (1) adjacent a water-permeable fibrous web (3). Fluid-transporting wicks extend from within the fibrous web into the hydrophilic layer, and are preferably formed by needling. The hydrophilic layer is preferably a peat moss composite board, and the fibrous web is preferably a nonwoven polyester fleece.
