  • Patent number: 9826876
    Abstract: A cleaning article includes a cleaning article sheet comprising a fabric substrate, wherein the fabric substrate includes pores therein, and wherein the fabric substrate has a background moisture percentage by weight, and liquid water disposed substantially and disconnectedly within the pores, wherein the liquid water is at moisture percentage by weight that is 5 to 150 percentage points higher than the background moisture percentage. The nonwoven substrate can include pores formed between and/or within the fibers and can have a background moisture percentage by weight. The substrate can include a treatment to increase the dielectric constant from the dielectric constant of the substrate without the treatment. The moisture of the article can be configured to exhibit a dielectric constant of at least 50% and up to 600% higher than the dielectric constant of the same article with only background moisture.

  • Publication number: 20100155004
    Abstract: Fibrous articles are disclosed containing an additive composition. The additive composition, for instance, may include a water-soluble film forming component and water-soluble modifying components that is deposited at least at the surface of a fibrous web. In some aspects, the additive composition includes polymers that demonstrate a certain LCST and melting temperature. In another aspect, the additive composition is applied to the fibrous web during the heated drying phase, such as with a Yankee dryer. The fibrous web with additive composition is then creped. The additive composition may improve the perceived softness of the web without substantially affecting the absorbency of the web in an adverse manner.
