METHOD OF MANUFACTURING AN EXUDATE MANAGEMENT LAYER FOR USE IN AN ABSORBENT ARTICLE
An absorbent article can have a topsheet layer, a liquid impermeable layer, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer. The absorbent article can further include an exudate management layer in fluid communication with the topsheet layer. In various embodiments, the exudate management layer can be positioned on a body facing surface of the topsheet layer. In various embodiments, the exudate management layer can be positioned between the topsheet layer and the absorbent core. The exudate management layer has a first component which defines an opening for direct passage of body exudates into the absorbent core. The exudate management layer has a second component which at least partially overlaps the first component of the exudate management layer and further extends in the longitudinal direction of the absorbent article in a direction towards the posterior region of the absorbent article.
ABSORBENT ARTICLES AND METHODS AND APPARATUSES FOR MAKING ABSORBENT ARTICLES WITH FRANGIBLE PATHWAYS
The present disclosure relates to absorbent articles including elastic laminates, and more particularly, to methods and apparatuses for making absorbent articles having elastic laminates in front and/or back waist regions with frangible pathways.
Method of manufacturing a diaper with moisture sensors
The present invention discloses a method of manufacturing a diaper that has multiple moisture sensing elements on interior side of its bottom impermeable layer or on any surface of the top permeable layer. The moisture sending elements are made by spraying conductive ink on a moving sheet of either the bottom impermeable layer or the top permeable layer, before other layers of the diaper are attached. Spraying of conductive ink on the moving sheet causes parallel lines of conductive inks to be formed on the layer. The parallel lines of conductive ink run through the entire length of either of the layers and are designed to get connected with a detecting device. When a user urinates inside the diaper, the moisture causes a closed circuit between at least two of the parallel lines of conductive inks. These formations of closed circuits, between parallel lines of conductive inks, are detected by the detecting device. Also, with increasing volume of moisture, the resistance of the closed circuits also tends to decrease. This rate of decrease of resistance is also detected by the detecting device and is used to calculate a volume of moisture present in the diaper. The detecting device then generates a suitable alarm to give an idea about the saturation level of the diaper. The process of manufacturing sensing elements by spraying conductive inks on moving sheet of layer reduces the processing and modification overhead of specially designed conductive ink printers and also does not impact the manufacturing time of a diaper manufacturing assembly line.
