MULTI-LAYERED NON-WOVEN STRUCTURE FOR USE AS A COMPONENT OF DISPOSABLE ABSORBENT ARTICLES
The present invention relates to multi-layered non-woven structures being useful as components of disposable absorbent articles and garments comprising super absorbent particles and thereby acts as a core. The invention thereby ensures that the body fluids can penetrate from a first layer, which acts as an acquisition layer, up to a third layer comprising SAP particles, the second non-woven layer serving to decrease the fluid volume per surface unit, as a conventional dispersion layer. However the second layer of the invention additionally acts like a non-return valve, preventing, or at least strongly limiting, any fluid transfer from the third layer to the first layer. Channels free of SAP can additionally be design to improve the inlet and rewet properties of the multilayer acquisition and distribution sheet non-woven material.
BIODEGRADABLE FABRIC AND USE OF SUCH FABRIC
The invention relates to a multilayered composite textile, comprising at least one first layer, comprising a first biodegradable polymer; and, at least one second layer, comprising a second layer fabric wherein the second layer fabric comprises second layer filaments; wherein said second layer fabric comprises a second biodegradable polymer, characterized in that, the visual degradation speed of the first layer is slower than the visual degradation speed of the second layer. The invention further relates to the use of such fabric for temporary weed control, temporary erosion control, as a hygienic article, or temporary packaging material.
AIRLAID COMPOSITE SHEET MATERIAL
Provided is a composite sheet that is particularly useful as an AQDL component in absorbent articles. The composite sheet includes a fluid acquisition component and an airlaid component. The airlaid component may include one or more airlaid layers that are successively formed overlying each other. Each of the airlaid layers are adjacent to, and in direct contact with, immediately adjacent layers of the airlaid component so that adjacent layers are in fluid communication with respect to each other. The fluid acquisition component includes a nonwoven fabric comprising a carded nonwoven fabric comprised of a plurality of staple fibers that are air through bonded to each other to form a coherent nonwoven fabric. The airlaid layer(s) include a blend of cellulose and non-cellulose staple fibers. The staple fibers may be bicomponent fibers having a polyethyelene sheath and a polypropylene or polyethylene terephthalate core, and mixtures of such fibers.
Textured Fibrous Structures
Textured fibrous structures, and more particularly textured fibrous structures having a plurality of deformations such that the textures fibrous structures exhibit novel surface height properties compared to known fibrous structures, and methods for making such textured fibrous structures.

Process for producing sheet-shaped material and sheet-shaped material obtained by said process
Provided is an environmentally friendly process for producing a sheet-shaped material having both an elegant, napped appearance and a soft texture, which qualities have not been achieved concurrently, and also exhibiting good abrasion resistance. The process of the present invention for producing a sheet-shaped material includes the successive steps of (a) adding a polyvinyl alcohol having a degree of saponification of 98% or more and a degree of polymerization of 800 to 3,500 to a fibrous substrate in an amount of 0.1 to 50% by mass relative to the total mass of fibers in the fibrous substrate; (b) adding a waterborne polyurethane to the fibrous substrate with the added polyvinyl alcohol; and (c) removing the polyvinyl alcohol from the fibrous substrate with the added waterborne polyurethane.
THERMOPLASTIC FILM AND AN ELASTIC COMPOSITE MADE WITH THE SAME
The invention features a thermoplastic film comprising greater than 70% by weight of a styrene block copolymer having an unsaturated mid block, diblock content of no greater than about 10% by weight and a MFR of from about 15 to about 200 ASTM D 1238 (190 C., 2.16-kg). The thermoplastic film can be used to form elastic composites that are useful in disposable articles (e.g. disposable absorbent articles).
CLEANING ARTICLE HAVING AN ABSORBENT BASE MATERIAL
The invention relates to a cleaning article (100) having an absorbent base material formed by a flat material (101), with a first (102) and a second side surface, wherein a coating (112) is provided on at least the first side surface (102) and confers to said first side surface (102) of the cleaning article (100) a higher frictional force than that of an uncoated first side surface (102), wherein the coating (112) comprises a plurality of coating lines (114) and, when an imaginary grid network (200) consisting of lines extending parallel, equidistantly and vertically to one another and with an edge length of 7 mm for each grid quadrant (206) is laid over the first side surface (102) of the cleaning article (100), said first side surface (102) has a first degree of coating coverage of at least 15% in the region of at least 5 grid quadrants (208) per 25 cm.sup.2, and a second degree of coating coverage of no more than 8% in the region of at least 5 grid quadrants (210) per 25 cm.sup.2.
CELLULITE DIMINISHING FABRIC
Disclosed is a fabric having a first side and a second side, that is provided at least on part of the first side with a pattern of protrusions, wherein the protrusions comprise an expanded heat-expanding material, namely a heat-expanding material that has been expanded by heating. A polymeric layer is provided to the woven fabric to coat at least part of the protrusions. Also disclosed is a process for the production of the fabric and a garment comprising the fabric.
