Abstract:
An absorbent composite material may be manufactured by applying a flexible absorbent binder polymer (FAB), also referred to herein as a flexible superabsorbent, during the creping step of conventional tissue manufacturing. As such, the costly process of applying FAB to a substrate by spraying or printing followed by drying may be eliminated. The creping step has the additional advantage of improving the flexibility and softness of the FAB treated fibrous web.

Additional aspects can include a treatment-material which is water soluble.
Abstract:
Superabsorbent material treated to resist damage when subjected to an Absorbent Product Processing Simulation Test, which simulates the mechanical damage that occurs during current commercial diaper manufacturing processes. The treated superabsorbent material has a centrifuge retention capacity of about 15 grams or greater of 0.9 weight percent sodium chloride per gram of the superabsorbent material and a gel bed permeability (GBP) at 0 psi swell pressure on pre-screened particles of about 200 (x 10 -9 cm 2 ) or greater. After subjecting the treated superabsorbent material to the Absorbent Product Processing Simulation Test, the treated superabsorbent may exhibit minimal reduction in GBP of pre-screened or un-screened particles at 0 psi or at 0.3 psi swell pressure, as well as possibly exhibiting minimal reduction in average particle size diameter (PSD). The superabsorbent material can be treated by adding an aqueous solution of a hydrophilic soft polymer to the superabsorbent material, mixing the superabsorbent material with the aqueous solution, and drying the superabsorbent material.

Abstract:
The present disclosure relates generally to a tissue product having a creping composition disposed onto at least one surface thereof to increase the softness of the article, while retaining or improving manufacturing efficiency. Preferably the creping composition comprises a first component that is cationic and a second component that is capable of forming a film. Preferably both the first and second components are water soluble. The first component carries a cationic charge that is capable of forming ionic bonds with the negatively charged fibers of the tissue web, thus providing a retention mechanism by which the creping composition is retained. The overall retention of the creping composition reduces the concentration of the composition in the machine process water, improving machine operability and runability.

An absorbent article comprises a signal element having a body- facing surface, a garment- facing surface, a longitudinal direction, a transverse direction and a z- direction. The signal element includes a water-soluble polymeric buffering film and a stimulation material. The water-soluble polymeric buffering film comprises a water- soluble base polymer. In some aspects, the stimulation material comprises a temperature change agent, and the signal element exhibits a surface temperature change of at least +/- 2 0C. In some aspects, the signal element exhibits a stimulation effect over at least two aqueous insults.
Abstract:
Fibrous products are disclosed containing an additive composition. The additive composition, for instance, comprises a water-soluble film forming component, a first water-soluble modifier component and a hydrophobic polymer component. In some aspects, the additive composition further comprises an additional water-soluble modifier component. The additive composition may be incorporated into the fibrous web by being combined with the fibers that are used to form the web. Alternatively, the additive composition may be topically applied to the web after the web has been formed. In one aspect, the additive composition may be applied to the web as a creping adhesive during a creping operation. The additive composition may improve the perceived softness of the web without substantially affecting the absorbency of the web in an adverse manner.
Abstract:
Generally stated, the present disclosure relates to wiping substrates such as wet wipes and dry wipes that include a thermal grill utilized to deliver a warming sensation. In an exemplary aspect, disposed on at least one structural layer of the wipe substrate is a thermal grill. The thermal grill includes an alternating pattern of thermally active areas and secondary areas that provide a feeling of warmth to a user of the wipe across the entire surface of the wipe. The thermally active portions of the wipe include a temperature change substance that when in liquid communication with an activation agent is adapted to provide a temperature change of at least 5°C from the temperature of the secondary portion. By providing a thermal grill with thermally active portions, the entire wipe gives the user of the wipe a warming sensation.
