A disposable absorbent article, such as a diaper The disposable absorbent article has a first topsheet with apertures large enough for low-viscosity fecal material to pass through to a secondary topsheet The secondary topsheet immobilizes the fecal material in position for dewatering, so that the liquid components of the fecal material are absorbed by the core and the solid components of the fecal material are separated from the liquid components This arrangement provides for easier cleaning of the wearer when the soiled disposable absorbent article is removed

The present invention is directed to ion-sensitive, water-dispersible polymers. The present invention is also directed to a method of making ion-sensitive, water-dispersible polymers and their applicability as binder compositions. The present invention is further directed to fiber-containing fabrics and webs comprising ion-sensitive, water-dispersible binder compositions and their applicability in water-dispersible personal care products.

A disposable absorbent article, such as a disposable diaper. The disposable absorbent article has a topsheet with apertures large enough for low-viscosity fecal material to pass through to a fecal material storage element. The fecal material storage element immobilizes the fecal material in position for dewatering, so that the solid components of the fecal material are separated from the liquid components of the fecal material and the liquid components can be absorbed by an absorbent core. This arrangement provides for easier cleaning of the wearer when the soiled disposable absorbent article is removed. The fecal material storage element may extend beyond one or more edges of the absorbent core.

Non-woven fabrics comprising yarn-like fiber groups of parallel and tightly compacted fiber segments, which groups include fiber segments circumferentially wrapped around at least a portion of the fiber groups. The groups are interconnected at junctures by fibers common to the plurality of such groups.

Non-woven fabric and method and apparatus for making the same

Non-woven fabrics comprising yarn-like fiber groups of parallel and tightly compacted fiber segments, which define apertures in the fabric. The apertures have substantially improved clarity and the yarn-like fiber groups have increased density.

978,385. Agglutinated fibrous fabrics; paper. JOHNSON & JOHNSON. March 18, 1963, No. 10589/63. Headings D1R and D2B. A print pattern bonded fibrous fabric 10 comprises a fibrous web and a water-resistant hydroxyethyl cellulose binder distributed thereon in a pattern of spaced segments 30, the hydroxyethyl cellulose having a degree of etherification corresponding to an ethylene oxide content of from 2% to 5% by weight and a degree of polymerization of from 250 to 1000 anhydroglucose units. The binder segments 30 may take any desired shape including lines, circles, annuli, ovals, ellipses, triangles, rectangles, squares, diamonds, parallelograms or combinations of such forms, either regularly or irregularly shaped. The binder lines may extend across the fabric at any desired angle to the longitudinal axis thereof; may be parallel or cross each other to form diamond or irregular polygonic figures; may be continuous or may be straight, curved, sinuous or irregularly wavy. The segments 30 cover from 7% to 50% of the total surface of the fabric. Specific geometric details of the pattern of the segments 30 are given in Specifications 833,697 and 744,839 and in U.S.A. Specifications 2,705,688 and 2,705,498. To form the fabric, the fibrous web, which may be in the form of a carded web or laid by papermaking techniques, is printed with an alkaline hydroxyethyl cellulose solution having a viscosity of from 450 to 2000 centipoises and a caustic content (sodium hydroxide content) of from 6% to 9 1 / 2 %. The hydroxyethyl cellulose is coagulated, e.g. in aqueous sulphuric acid, into an alkali-soluble, water-insoluble form to function as the binder. Specified fibres are cotton, viscose rayon, silk, wool, flax, mineral fibres, cross-linked cellulosic fibres, cellulose esters such as cellulose acetate and cellulose triacetate, saponified cellulose esters, polyamides such as nylon 6 and nylon 66, polyesters, vinyl fibres, acrylic fibres and modacrylic fibres. The fibres may be textile length fibres of from # inch to 2¢ inches in length or paper making length fibres of from 1 / 16 to # inch in length or a mixture of the two. Preferably the fibres have a denier between 1 and 5 but fibres having a denier of up to 15 may be used. The fabric may be formed from a single fibrous web having a weight of from 35 to 250 grains per square yard or may be formed from a laminate of webs having a combined weight of from 140 to 3000 grains per square yard. The fabric may contain from 1% to 10% by weight, based on the weight of the fibrous web, of the binder. Specification 836,397 and U.S.A. Specifications 2,676,363, 2,676,364 and 2,847,411 also are referred to.

Fibrous structures and methods of making the same

Bonded fibrous nonwoven textile fabrics having excellent strength and textile-like softness, drape and hand which are intermittently bonded with synthetic resins in predetermined print patterns of binder areas having a relatively high, uniform concentration of from about 50% to about 120% by weight of resin binder in the binder areas, based on the weight of the fibers therein, said binder areas having very sharply defined borders or edges with a minimum of binder feathering thereat whereby the optical density of the bonded fibrous nonwoven textile fabric very sharply increases from substantially zero to a maximum of at least from about 0.6 to about 1.0 or greater in a distance of less than about 1 mm. (0.04 inch), and methods of depositing such synthetic resins from colloidal aqueous dispersions thereof onto wet fibrous webs to form the bonded fibrous nonwoven textile fabrics, comprising the use of (1) metal complex coordination compounds and (2) synthetic resins and/or surfactants, at least one of which contains a specific coordinating ligand capable of being affected by ions of said metals to control the total migration of the resin binder during such deposition.

Bonded nonwoven fabrics

Films, sheets, expanded or foamed products, fibrous webs, and similar synthetic, organic, polymeric shaped articles and structures having surfaces with improved bonding and adhesion capabilities, increased fluid absorbency rates, and enhanced fluid wicking properties; and processes and apparatus for obtaining such improved capabilities and enhanced surface properties and characteristics by exposing said shaped articles to the action of an electrical corona discharge in an atmosphere of a reactive gas which does not have an affinity for electrons and which is also capable of acting as a chemical reducing agent, such as carbon monoxide, for example.
