There is provided a resilient, three dimensional material having fibrous texture and appearance and capable of fluid handling. It consists of a top surface and a bottom surface wherein fiber-like elements typically extend from one surface to the other forming flat to undulating surfaces characterized by a multiplicity of interconnected fluid passageways. Deformed, discontinuous film-like or encapsulated regions connect fiber-like elements and stabilize the material. The material of this invention is unique based on the three principle characteristics which are communicated in this application: 1) f(&#x3c8;)&#x3c;0.87, 2) SA/VV&#x3c;186 cm/cm, and 3) caliper&#x3c;0.150 inches. This material is useful for a number of purposes, such as for use as a liner for personal care products like diapers, absorbent underpants, swim wear, feminine hygiene products, adult incontinence products and the like. The properties of the material may be tailored within the ranges of this invention to deliver optimal material performance for use in specific personal care products.

Creped materials

A personal care product that has a liquid impermeable backsheet, a liquid permeable topsheet, and an absorbent composite located between the topsheet and backsheet. The absorbent composite has an upper layer made of synthetic fiber with at most 20 weight percent pulp and the upper layer has a density between about 0.03 and 0.15 g/cc and a basis weight between about 20 to 75 gsm. The composite has a lower layer having from 80 to 95 weight percent pulp, at most 20 weight percent binder, and has a density greater than the upper layer and between 0.06 and 0.20 g/cc, and a basis weight between 120 and 200 gsm.

Pulp and synthetic fiber absorbent composites for personal care products

There is provided an absorbent system that not only takes in fluid, but then transfers that fluid further beneath the first composite. This is achieved in this invention through paired permeability, capillarity, and void volume of the first and second composites. The invention is an absorbent system composed of at least two absorbent composites that have complementary structural/surface energy characteristics. Such an absorbent system has a first absorbent Composite A which has a first permeability, a first capillarity, and a first void volume and at least one second absorbent Composite B which has a second capillarity and a second porosity multiplied by second thickness. The first absorbent Composite A is in liquid communication or contact with at least one second absorbent Composite B, such that the first absorbent Composite A, and the second absorbent Composite B have a fluid partitioning amount in Composite A, a third triple intake time (IT3) and a rewet value.

Personal care products having reduced leakage

There is provided an intake/retention/transfer material for personal care products like feminine hygiene products, which is a heterogeneous composite containing between 5 and 25 weight percent of a superabsorbent or gelling material and having a density less than 0.17 g/cc. A more particular embodiment contains less than 20 weight percent and a still more particular embodiment contains 15 weight percent or less of a superabsorbent or gelling material. Also provided are absorbent articles which contain the class of intake/transfer materials mentioned above along with additional absorbent layers such that the absorption of a menses simulant provides fluid partitioning of less than 72% of fluid in the intake/transfer/retention composite. Additionally said composite should have retention capacity values greater than 2.7 g/g.

Personal care product with fluid partitioning

A film cover for use in absorbent materials such as feminine care products, surgical drapes, fenestration reinforcement, absorbent pads and the like including a polymeric film having a top planar surface and a bottom planar surface and forming a plurality of apertures, at least a portion of which have an aperture region having a higher wettability than a portion of the top planar surface of the polymeric film.

Apertured film covers with localized wettability and method for making the same

Disclosed herein is a liquid absorbent material that is particularly useful as a liner material for personal care absorbent articles such as diapers, training pants, incontinence garments, sanitary napkins, bandages and the like. The material contains a plurality of peaks across its surface at spaced-apart intervals separated by channels. Disposed within the peaks is a liquid absorbing material capable of absorbing body exudates and liquids in general. Due to the materials and the nature of the construction of the present invention, when used as a liner material for personal care absorbent articles such as diapers, it tends to reduce the total surface area in contact with the infant's skin and it also provides a plurality of air channels within the diaper from the front waistband to the back waistband of the diaper thereby providing a path for increased air circulation. The material of the present invention has other uses as, for example, a packing or liner material for packaging and shipping materials containing liquids. In addition, the peaks can contain other additive such as soaps so the material can be used as a wash pad or cloth.

Liquid absorbent material for personal care absorbent articles and the like

There is provided a distribution material for personal care products which is a fabric which wicks artificial menses according to a horizontal wicking test a distance of about 1 inch in less than about 1.5 minutes. Materials meeting this performance criteria generally have a pore size distribution with a high percentage (usually more than 50 percent) of pore diameters between about 80 and 400 microns and a density below about 0.15 g/cc.

Stabilized absorbent material for improved distribution performance with visco-elastic fluids

A distinctive absorbent article includes a backsheet layer which has a width dimension and a length dimension, and which includes a front waistband section, a back waistband section, and an intermediate section interconnecting the front and back waistband sections. An absorbent body is superposed on the backsheet layer, and an intermediate transfer layer, which is liquid permeable, is disposed in facing relation with the absorbent body to generally sandwich the absorbent body between the backsheet and transfer layer. The transfer layer has an appointed bodyside, inner surface, and a bodyside liner layer is located on the inner surface of the transfer layer. The bodyside liner comprises a bonded carded web which has a basis weight within the range of about 15-40 gsm and is composed of bicomponent fibers having a fiber denier within the range of about 1.0-3.0 dpf. The bodyside liner is constructed to provide for a Penetration rate index of at least about 1.5 ml/sec and a Retention index of not more than about 0.8 gm.

Absorbent article having a liner which exhibits improved softness and
