摘要:
The invention relates to a layered product comprising at least one natural fiber layer comprising a web of natural fibers and at least one SAP layer comprising a non-woven substrate comprising a thermoplastic polymer fibers and a superabsorbent polymer adhered to thermoplastic polymer fibers, wherein the non-woven substrate is a high loft fabric, for example an airlaid or spunlaid non-woven, and wherein the natural fiber layer and the SAP layer are connected to each other by needle punching, stitch bonding or using an adhesive. The invention further relates to a process to prepare the layered product and the use of the layered product in for example horticulture.
摘要:
A sheet-like article (1) for an absorbent article of the invention includes a plurality of absorbent units (4), each including: a long base portion (2); and water-absorbent polymer particles (3) that are fixed to a surface of first side of the long base portion (2). In the sheet-like article (1), the absorbent units (4) are arranged such that the longitudinal direction thereof is oriented in one direction. When the water-absorbent polymer particles (3) absorb a liquid, the water-absorbent polymer particles (3) swell beyond the lateral side edge portions (2s), of the long base portion (2), that extend along the longitudinal direction, and a position, in the thickness direction, of each long base portion is varied from the position thereof before absorbing the liquid.

An absorbent article having an outwardly body-facing surface and an outwardly garment-facing surface Is provided. The absorbent article contains a topsheet, backsheet, and an absorbent core positioned between the topsheet and the backsheet. The backsheet contains a nonwoven facing laminated to a film. The nonwoven facing contains a first nonwoven web containing a plurality of fibers formed from a first polyolefin composition and a second nonwoven web containing a plurality of fibers formed from a second polyolefin composition. The first polyolefin composition contains at least one ethylene polymer and the second polyolefin composition contains at least one rigid propylene polymer and at least one ductile propylene polymer. The second nonwoven web defines the garment-facing surface of the article.
摘要:
An absorbent article includes a liquid-pervious sheet, an outer covering sheet, and an absorbent structure sandwiched between the liquid-pervious sheet and the outer covering sheet. The absorbent structure includes a liquid-absorbent mixture composed of super-absorbent polymer particles and fluff pulp and nonwoven fabric sheet formed from long fibers of thermoplastic resin. The nonwoven fabric sheet is put in contact, along at least one surface thereof, with the liquid-absorbent mixture and has cross points at which the long fiber sealed together, and a nap height defined by a difference between a thickness measured before a napping test and a thickness measured after the napping test is at least 0.5 mm.
摘要:
A body fluid absorbent panel including fibers 27 containing hydrophilic fibers by 80 - 100 % by weight and superabsorbent polymer particles 28 contains heat-fusible fibers which are fused to intertwine the fibers and thereby to form a three-dimensional network structure wherein the high absorption polymer particles 28 are held between respective pairs of the adjacent fibers or bonded to the fibers by means of binder, and thereby falling off of the polymer particles can be prevented and the absorption efficiency can be improved.

Une serviette hygiénique pour femmes utilisée en cas d'incontinence urinaire comprend au moins un corps absorbant ayant la forme d'un coussin relativement plat, placé entre une couche étanche au liquide disposée sur le dessous et une couche en tissu dispersant le liquide située sur le dessus, ce corps absorbant étant entouré d'une enveloppe en matière non tissée. Le corps absorbant, la couche de dispersion du liquide liée à ce corps par un procédé thermoplastique et la couche étanche peuvent être pliés ensemble (6) pour former un pli inversé, dans lequel un espacement longitudinal situé entre les couches supérieures (11, 12) orientées vers l'utilisateur sert de canal de drainage (13) vers une couche support sous-jacente cohérente (10). Le corps absorbant contient une matière surabsorbante répartie uniformément et des fibres thermoplastiques supplémentaires de manière à présenter une structure en réseau renforcée et à permettre ladite liaison thermoplastique de la couche de dispersion du liquide. Le produit peut avoir une quantité de corps absorbants avec une concentration variable de matière surabsorbante, et ce type de produit peut également comporter, comme couches internes de transfert de liquide un corps plan non plié de fibres de cellulosiques, dépourvu de matière surabsorbante.

Des structures absorbantes comprennent un noyaux fibreux superabsorbant dont est solidaire une couche de revêtement. On peut former ces structures en produisant des bandes de mélanges de fibres thermoplastiques et de fibres superabsorbantes, ainsi qu'une bande formée essentiellement de fibres hydrophobes thermoplastiques. On relie les couche par liaison thermique. Ces structures sont utiles dans des produits absorbants jetables, notamment des serviettes hygiéniques.
摘要:
In absorbent products, such as sanitary napkins, discreet areas of dry fibrous materials such as fluid-repellent materials are precisely placed in various planes within the product so as to provide barriers to bodily fluid leakage from the product. In a preferred embodiment, hydrophobic fibers are placed around the periphery of a central absorbent area of an absorbent product to discourage and/or prevent side or end leakage from the product.
