The present invention relates to a method for fabricating absorbent article having multiple layers, and deformed zones of targeted performance, and colored regions, the method comprising the steps of forming discrete features on at least one layer, printing colored regions on at least one layer, integrating multiple layers to form an absorbent assembly, and cutting the absorbent assembly into individual absorbent articles, wherein the steps are carried out continuously.
摘要:
The present disclosure relates to methods and apparatuses sensing emitted light caused by fluorescence of adhesive to determine characteristics of absorbent structures during the manufacture of absorbent articles. Some absorbent articles may have absorbent structures that include an absorbent core disposed between a topsheet and a backsheet. And one or more of the absorbent structure components may be assembled with adhesive that fluoresces when excited by ultraviolet light. Aspects of the present methods relate to an inspection system that may be configured to interact with, monitor, and/or control a converting line. The inspection system may include a radiation source that illuminates a surface of an absorbent structure with ultraviolet light. A sensor may be adapted to receive light caused by fluorescence of the adhesive while being irradiated with the ultraviolet light. In turn, the inspection system may determine characteristics of the absorbent structure based on the detected emitted light.

摘要:
A method of making an absorbent pad, and the absorbent pad so made, including a porous under layer and an absorbent body including a pulverized pulp and a super-absorbent materials bonded to and between the porous layers; characterized in that the absorbent body is applied between the porous layers before bonding thereto by: applying a first layer of pulverized pulp to the porous under layer; applying a layer of the super-absorbent material over the first layer of pulverized pulp; and applying a second layer of the pulverized pulp over the super-absorbent material layers. One or more of the above layers also includes a deodorizer material which may include a deodorizer agent, to reduce odors, an anti-inflammatory agent to prevent skin erythema, and/or a perfume fragrance.

A disposable absorbent article comprising an absorbent core (10), the absorbent core comprising: (a) a storage layer (60); and (b) a durable hydrophilic fluid pervious core wrap (42), the core wrap surrounding at least a portion of the storage layer, said core wrap comprising: (i) a core wrap substrate; and (ii) a hydrophilicity boosting composition coated on the substrate, the hydrophilicity boosting composition comprising a hydrophilicity boosting amount of nanoparticles (75), wherein the nanoparticles have a particle size of from about 1 to about 750 nanometers. Methods of preparing disposable absorbent articles are also provided.
摘要:
An apparatus and method for forming tow-based absorbent structures having a single casing sheet are disclosed. The apparatus has a tow supply mechanism for providing tow material, a particulate matter supply mechanism for providing particulate matter, and a casing sheet supply mechanism for providing casing sheet material. The apparatus also has a vacuum draw roll having a foraminous center surface that has a width defined by a first edge and a second edge and is rotatable about a first axis. The vacuum draw roll is positioned to receive the tow material, the particulate matter and the casing sheet material to form a open core composite supply. The apparatus also has one or more angled surfaces positioned to create one or more obtuse angles in the open core composite supply, and one or more folders to further fold the one or more obtuse angles in the open core composite supply to form a folded core composite supply.
摘要:
An absorbent core (28) for absorbent articles (20) such as diapers comprising a core wrap (16, 16') comprising a top side (288) and a bottom side (290), an absorbent material (60) between the top side and the bottom side of the core wrap, a first and second longitudinally-extending channel-forming areas (26a, b) substantially free of absorbent material preferably through which the top side of the core wrap is attached to the bottom side of the core wrap disposed on opposite sides of the longitudinal axis (80). The core has a central absorbent zone (62) between the first and the second channel-forming areas and a first and second lateral absorbent zones (61, 63) disposed laterally outwardly. The absorbent core comprises at least one transversal folding line (66, 66'), preferably at least two transversal folding lines, in the region where the longitudinally-extending channel-forming areas are present.
