Fibrous Nonwoven Web with Uniform, Directionally-Oriented Projections and a Process and Apparatus for Making the Same
20190151167 · 2019-05-23 ·

A process and apparatus is used for making a fibrous nonwoven web with uniform, directionally-oriented projections by depositing fibrous material onto a first forming surface with holes positioned above a second forming surface with both forming surfaces traveling at different speeds to one another. As the fibers are deposited onto the first forming surface, a portion of the fibers are drawn down into the holes of the first forming surface forming the projections which contact the second forming surface. Due to the speed differential between the two forming surfaces the projections are uniformly skewed in the same direction. The resultant material is particularly suited for use as a wiping material which can be more abrasive in one direction but which is softer to the touch when wiped in the opposite direction thus making it a dual purpose material.

Method Of Creating Conforming Features In An Absorbent Article

A method of making a disposable absorbent article with a plurality of conforming features is described. The conforming features may be provided to the absorbent article in a variety of zones to allow for customizable conformance in particular regions of the absorbent article. And, the provision of these zones can also allow for customizable fluid kinetics in particular regions of the absorbent article.

Absorbent Article With Conforming Features

A disposable absorbent article has a topsheet; a backsheet; an absorbent core disposed between the topsheet and the backsheet; and a first plurality of conforming features in at least the absorbent core or a combination of the absorbent core and the topsheet. At least a portion of the are depressions, wherein the depressions have a depression centerline bisecting a length and/or width of the depression. A first strut forms a first sidewall of the depression opposite a second sidewall of the depression formed by a second strut, wherein neither of the first strut nor the second strut extend longitudinally and/or laterally beyond the depression centerline by more than 0.75 mm.

Absorbent Article With Conforming Features

A disposable absorbent article is described herein. The disposable absorbent article includes a topsheet, a backsheet, and an absorbent system disposed between the topsheet and the backsheet. At least a portion of the has a plurality of conforming features such that the absorbent article has a blot residual value of less than 30 mg and a bending stiffness of less than 12.

Absorbent Article With Conforming Features

An absorbent has longitudinal and lateral centerlines, first, second, and target regions, the target region being disposed between the first second regions. Each of the first, second target regions extend laterally across the disposable absorbent article. The disposable absorbent article also has a topsheet; a backsheet; an absorbent core disposed between the topsheet and backsheet; a fluid management layer disposed between the topsheet and absorbent core; and a target zone disposed in the target region. The target zone has a first plurality of conforming features in at least the absorbent core or a combination of the absorbent core and at least one of the topsheet or fluid management layer. The absorbent article also has a long fiber network.

Enzyme Degradable System for Undergarments and Feminine Hygiene Articles
20190111176 · 2019-04-18 ·

An enzyme-degradable system for undergarments and feminine hygiene articles works to decompose the undergarments and feminine hygiene articles upon being triggered by bodily fluids, such as urine. The undergarment or feminine hygiene article comprises an absorbent core, an inner sheet of biodegradable material, and an outer sheet of biodegradable material. The core includes at least one of the following: a cellulose material, a wood pulp, a biodegradable and bioactive thermoplastic aliphatic polyester derived from renewable resources (polylactic acid plasticPLA), and a superabsorbent polymer (SAP). The inner and outer sheets comprise a plant based cellulosic nonwoven material. The cellulose enzyme decomposes the absorbent core, the inner sheet, and the outer sheet upon contact with a bodily fluid. The cellulose enzyme may include DIS-1018 Cellulose-AN, a pH buffer, and additives. Fasteners made from a resilient, biodegradable material help secure the undergarments and feminine hygiene articles to the body.
