Abstract: A pre-loaded cleaning substrate, and related systems and methods for picking up particles with an aspect ratio (L/D) greater than 300 (e.g., hair), or greater than 1200 (e.g., particularly long hairs). The substrate (e.g., a nonwoven) may include only a single layer of material. The pre-loaded substrate is loaded (e.g., during manufacture) with a cleaning composition. The fibers of the substrate may have an average diameter less than 15 μm, the substrate may have an air permeability of 35 ft3/min to 75 ft3/min, and the liquid cleaning composition may have a surface tension of less than about 50 dynes/cm. Together, the combination of the particular substrate and cleaning composition may facilitate markedly improved ability to pick up high L/D aspect ratio particle debris (e.g., such as hair), while retaining such particles (e.g., providing hair retention index values of at least 20).

Abstract: Systems including a resealable container and pre-moistened wipes packaged therein, the wipes including one or more characteristics correlated to desired properties, such as high durability, mileage, cleaning composition retention, efficacy, or the like. Pulp substrates typically include an anionic charge, which can result in binding or retention of a cationic biocide such as a quaternary ammonium compound while the remainder of the composition is released from the wipe (e.g., through squeezing, wiping or other compression). The present wipes may be specifically tailored to provide efficacy against Staphylococcus aureus population within 10 seconds to about 5 minutes, to include particular pore size distribution characteristics, and/or to include a mileage absorbency/desorbency factor (“MABDF”) value that is greater than 50. High MABDF values are indicative of good handfeel characteristics, improved more uniform dosing of composition loaded in the wipe, good microefficacy characteristics, and the like.

Abstract: Pre-moistened wipes that include one or more characteristics correlated to desired properties, such as high durability, mileage, cleaning composition retention, efficacy, or the like are described. Pulp substrates typically include an anionic charge, which can result in binding or retention of a cationic biocide such as a quaternary ammonium compound while the remainder of the composition is released from the wipe (e.g., through squeezing, wiping or other compression). The present wipes are specifically tailored to release at least 20% of the quaternary ammonium compound to a target surface, and exhibit at least a 3-log reduction in Staphylococcus aureus population within about 10 seconds to 5 minutes. Such release and efficacy is achieved without the presence of any cationic biocide release agent (e.g., latex or a cationic salt) included in the cleaning composition or elsewhere within the pre-loaded disinfecting wipe.

Abstract: Methods for forming multi-layer substrates including top and bottom surface layers and a melt softened thermoplastic material layer between the exterior surface layers, where the thermoplastic material includes polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F.-350° F. The 3 (or more) layers are assembled, and heated, melt softening the thermoplastic material, causing bonding of the thermoplastic layer to the exterior surface layers. A cleaning composition may be loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel between the surface layers. Adhesion between the surface layers and the thermoplastic layer is provided by the thermoplastic material itself, which bonds to groups of fibers in the surface layers. The process does not require chemical adhesives, any processing water, drying, or the like, so as to be possible with low capital investment.

Abstract: Methods for manufacturing wipes including melamine entangled into a nonwoven, and associated articles of manufacture. Such a method may include providing a melamine sheet (e.g., contiguous, rather than discrete melamine particles), providing first and second nonwoven sheets, and positioning the melamine sheet between the first and second nonwoven sheets. The sandwich structure is hydro-entangled at high pressure to force the melamine material to become entangled into the nonwoven material, to a degree that a portion of the melamine is actually exposed on the exterior face(s) of the wipe, which are generally provided by the nonwoven sheets. Such a wipe exhibits the drapability of a wipe, with the scrubbing benefits (e.g., very effective cleaning of baseboards, crayon off walls, etc.) of melamine, with greater durability than existing melamine cleaning articles, which tend to quickly crumble during use.
