Treated nonwoven having an affinity for an active ingredient
A nonwoven having a high affinity for an active ingredient is proved, the nonwoven having at least one high surface area fiber in addition to the active ingredient.
Process for making an absorbent article comprising a topsheet/acquisition layer laminate
A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an intermediate layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The intermediate layer has a first and second surface. The topsheet and intermediate layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the intermediate layer and simultaneously mechanically deformed which combines the topsheet with the intermediate layer. The topsheet web and intermediate layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the intermediate layer to provide a topsheet/intermediate layer laminate web having three-dimensional protrusions.
NONWOVEN MICROFIBER PRINT RECEPTIVE SURFACE
The present disclosure presents a process of forming an aqueous ink onto an ink receptive laminate of a liquid impermeable absorbent article film by ink-jet printing. The process generally includes the steps of corona treating the laminate, applying meltblown fiber onto the laminate and applying ink droplets that are smaller than the meltblown fiber onto the fiber and laminate. An ink-jet printed laminate is also disclosed.
PROCESS FOR MAKING AN ABSORBENT ARTICLE COMPRISING A TOPSHEET/ACQUISITION LAYER LAMINATE
A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an intermediate layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The intermediate layer has a first and second surface. The topsheet and intermediate layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the intermediate layer and simultaneously mechanically deformed which combines the topsheet with the intermediate layer. The topsheet web and intermediate layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the intermediate layer to provide a topsheet/intermediate layer laminate web having three-dimensional protrusions.
SYSTEMS AND METHODS FOR WOUND DEBRIDEMENT
Methods of debriding a wound include applying a wound debridement material in frictional contact across at least a portion of a wound surface of a patient and removing tissue from the wound surface via adherence of the tissue to the wound debridement material without leaving solid debris of the wound debridement material on the wound surface after the application of the wound debridement material. A wound debridement material comprising a solid porous foam soaked by a fluid suitable for use in such methods is also provided.
Toilet Training Undergarment Disposable Insert Liner
The present invention describes an undergarment pantiliner which is worn with a child's underwear, to aid in toilet training while protecting undergarments from soiling. The invention is directed to in particular the situation in which the child has mastered urination but continues to have challenges with controlling bowel movements. The pantiliner is made up of sheets of non-woven disposable fabric and other materials which protect the wearer's underwear from stains and/or exudates. It is meant to absorb a little wetness but let most fluid flow through while retaining excrement and exudate. Use of the item aids the child's self-confidence to believe he can transition to be fully toilet-trained by supporting his sense of independence.
Process for making an absorbent article comprising a topsheet/acquisition layer laminate
A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an acquisition layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The acquisition layer has a first and second surface. The topsheet and acquisition layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the acquisition layer and simultaneously mechanically deformed which combines the topsheet with the acquisition layer. The topsheet web and acquisition layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the acquisition layer to provide a topsheet/acquisition layer laminate web having three-dimensional protrusions.
Technique for Forming Porous Fibers
A method for forming a fiber is provided. The method comprises extruding a matrix polymer and a nanoinclusion additive to form a thermoplastic composition in which the nanoinclusion additive is dispersed within a continuous phase of the matrix polymer. The extruded thermoplastic composition is thereafter passed through a spinneret to form a fiber having a porous network containing a plurality of nanopores, wherein the average percent volume occupied by the nanopores within a given unit volume of the fiber is from about 3% to about 15% per cm.sup.3.
Extrusion bonded laminates for absorbent articles
An absorbent article of the present invention may comprise a topsheet, an outer cover, and an absorbent core disposed therebetween. The outer cover may comprise an extrusion bonded laminate. The EBL may comprise a multi-layer coextruded elastomeric film and a nonwoven. The film may comprise a core layer, a first outer layer, and a second outer layer, wherein the core layer is between the first and second outer layers. The nonwoven may comprise fibers and/or filaments. The first outer layer may be non-adhesively joined to the nonwoven via extrusion coating. Further, the outer cover may be elastic to at least about 50% engineering strain. The nonwoven may have high chemical affinity for the first outer layer. The first outer layer may have a low chemical affinity for the core layer; and the multi-layer coextruded elastomeric film may have a basis weight no greater than about 40 gsm.
ABSORBENT STRUCTURE
An absorbent structure including a distribution layer and a storage layer is disclosed. The distribution layer has two or more stratums. The two or more stratums include a body facing stratum and a subsequent stratum below the body facing stratum. The density of the subsequent stratum is a fraction of the density of the body facing stratum and the porosity of the subsequent stratum is a multiple of the body facing stratum porosity.
