20130079741 | THIN ABSORBENT ARTICLE - Disclosed is an absorbent article containing an absorbent body which is thin before absorption, and even after absorption does not inhibit super absorbent polymer (SAP) swelling and wherein deformation such as twisting is unlikely to occur. The disclosed absorbent article comprises a liquid-permeable front surface sheet, a liquid impermeable rear surface sheet, and an absorbent body which is located between the two sheets. The absorbent body is formed from a super absorbent polymer containing layer and a non-woven fabric layer, with the non-woven fabric layer having regions wherein the between-fibre void ratio is relatively large and regions wherein the between-fibre void ratio is relatively small. The tip sections of the fibres forming the non-woven fabric layer are greater in number in the regions wherein the between-fibre void ratio is relatively large than the regions wherein the between-fibre void ratio is relatively small, and the non-woven fabric layer has expansibility. | 03-28-2013 |
20130253461 | Article with Nonwoven Web Component Formed with Loft-Enhancing Calender Bond Shapes and Patterns - An article having as a component a section of nonwoven web formed predominately of polymeric fibers is disclosed. The section of nonwoven web may have a pattern of consolidating bonds impressed on the surface. The bonds may have at least one bond shape; and the bond shape may have a perimeter with a greatest measurable length and greatest measurable width. The perimeter may have a convex portion and an aspect ratio of length/width of at least 2.5. Other features may be imparted relating to the density and orientations of the bonds relative machine and cross directions of the web. The bond shape reflects the shape of a corresponding bonding protrusion on a bonding roller. It is believed that the shape, density and/or orientation of the bonding protrusions affect air flow through the bonding nip in a way that may be utilized to enhance loft of the resulting bonded nonwoven web. | 09-26-2013 |
20140039437 | METHOD AND APPARATUS FOR PRODUCING COMPOSITE STRUCTURE - The present invention relates to a method and apparatus for forming a composite structure, preferably for use in an absorbent structure used within the personal hygiene industry, such as for instance feminine hygiene garments, baby diapers and pants and adult incontinence garments. The present invention preferably provides a method and apparatus for depositing and positioning particulate materials in a desired pattern onto a moving carrier layer. The method allows accurate forming of a pattern of particulate material clusters at high production speed having improved attachment properties, with reduced raw material usage and relative low cost. The present invention foresees in the need for improved thin, flexible, lightweight absorbent structure having optimal absorption, distribution and retention. | 02-06-2014 |
20140121626 | Fluid-Entangled Laminate Webs having Hollow Projections and a Process and Apparatus for Making the Same - The present invention is directed to a fluid-entangled laminate web and the process and apparatus for its formation as well as end uses for the fluid-entangled laminate web. The laminate web includes a support layer and a nonwoven projection web having a plurality of projections which are preferably hollow. As a result of the fluid-entangling process, entangling fluid is directed through the support layer and into the projection web which is situated on a forming surface. The force of the entangling fluid causes the two layers to be joined to one another and the fluid causes a portion of the fibers in the projection web to be forced into openings present in the forming surface thereby forming the hollow projections. The resultant laminate has a number of uses including, but not limited to, both wet and dry wiping materials, as well as incorporation into various portions of personal care absorbent articles and use in packaging especially food packaging where fluid control is an issue. | 05-01-2014 |
20140324009 | Aperture-Patterned Fibrous Nonwoven Web - An apertured fibrous nonwoven web with an array of apertures is made that allows for increased functionality and improved aesthetic appearance. The material is particularly well-suited for use as a topsheet or bodyside liner material for personal care absorbent articles including, but not limited to feminine hygiene products, diapers, diaper pants, training pants, adult incontinence devices, bandages and the like. The fibrous nonwoven web includes first, second and third arrays of apertures with varying characteristics that provide improved fluid handling properties for various body exudates. | 10-30-2014 |
20150094682 | Method Of Forming An Absorbent Structure - A liquid absorbent structure is made by dry laying a fibrous web having incorporated therein a superabsorbent material, and applying an aqueous composite stabilizer to at least one surface of the web. The aqueous composite stabilizer imparts integrity to the resulting structure without substantially impairing the effectiveness of the superabsorbent material to absorb liquid while forming the absorbent structure without removing the water from aqueous composite stabilizer or drying out the absorbent structure. The absorbent composite absorbs the water from the aqueous composite stabilizer. The absorbent composite comprises about 70% by weight of a superabsorbent material. | 04-02-2015 |
20150297415 | BREATHABLE STRUCTURAL WEB AND BREATHABLE STRUCTURAL WEB-FORMING APPARATUS - A breathable structural web includes a layered structure having at least a layer of a non-woven material. The layered structure includes a base layer portion that has opposite first and second sides, a plurality of hollow protrusions that are disposed at the first side and that protrude and that are tapered from the base layer portion in a first direction, and a plurality of indented portions that are disposed at the second side, that extend from the base layer portion in a second direction opposite to the first direction, and that respectively define a plurality of recesses which open in the first direction. The hollow protrusions are scattered among the indented portions. | 10-22-2015 |
20160030258 | PULPLESS ABSORBENT CORE AND METHOD OF CORE FORMING - A pulpless core is provided with flexibility for superabsorbsnt expansion by using elastic strands stretched and coupled to a nonwoven layer, and then relaxed partially to create receiving valleys (puckers) and the puckers are provided with superabsorbent polymer, and then a layer of nonwoven or acquisition film can be coupled on top of nonwoven/elastic/sap carrier layers to create an absorbent core laminate. | 02-04-2016 |
