  • Patent number: 11311424
    Abstract: Pulpless absorbent cores and methods of manufacture are disclosed. A method of forming a pulpless absorbent core may comprise moving a foraminous forming surface having un-masked portions and masked portions in a machine direction, the un-masked portions defining an absorbent core region. The method may further comprise depositing particulate material at a velocity of less than 1200 meters per minute in the absorbent core region while applying a vacuum. The absorbent core region may comprise: a front core region spanning a first half of the absorbent core region and a rear core region spanning a second half, wherein the front core region trails the rear core region in the machine direction, and the masked portions of the foraminous forming surface block airflow through the forming surface to cause greater than 60% of the particulate material deposited in the absorbent core region to locate in the front core region.

  • Patent number: 10278875
    Abstract: An absorbent article includes a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body between the top and back sheets. The top sheet has first and second areas, each of which includes a blood lubricity-imparting agent that has a kinematic viscosity of 0.01-80 mm2/s at 40° C., a water hold percentage of 0.01-4.0 mass %, and a weight average molecular weight of less than 1,000. The first area overlaps at least partially with an excretory orifice contact area of the top sheet that is configured to contact with the excretory orifice of the wearer. The second area is arranged more to a rear side in a lengthwise direction of the absorbent article than is the first area. A basis weight of the blood lubricity-imparting agent in the first area is higher than that of the blood lubricity-imparting agent in the second area.

  • Patent number: 10279071
    Abstract: An odor control layer for personal care products has a composition that has a PEG or PEG copolymer composition applied thereto. The layer can be placed in a personal care product, such as a diaper, training pant, absorbent under pant, adult incontinence product, or feminine hygiene product. Additional odor control layers may include silver nanoparticles and activated carbon compositions. In an alternative form, a single odor control layer includes the PEG composition and the activated carbon and/or silver nanoparticle compositions. A cleansing composition with PEG and possibly active carbon and silver nanoparticles may be combined with the personal care product to form a kit.
