Melamine wipes and methods of manufacture
11365496 · 2022-06-21 · ·

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.

Thermal/acoustical liner

A multi-layer liner material for use as a thermal and acoustical insulator which is lightweight, breathable, hydrophobic, oleophobic and fire-resistant. A central insulation core layer is contacted on a first surface by a first highly breathable layer and on a second surface by a second highly breathable layer, such that these three layers are resistant to water or oil penetrating the insulation core layer causing the liner to gain weight. The first and second highly breathable layers are preferably made from inherently flame resistant fibers and treated with a fluorocarbon surface treatment for water repellency, UV resistance and mold/mildew resistance. The first highly breathable layer is adjacent a facing layer while the second highly breathable layer is adjacent a backing layer. At least one surface of one of the first or second highly breathable layers, or facing or backing layers may include a carbon printing pattern to provide ESD protection.

THERMAL MANAGEMENT SYSTEM AND DEVICE
20220158273 · 2022-05-19 ·

The invention relates to thermal management systems for devices that generate heat, including electronic devices such as portable electronics, for example, cell phones, electronic components, and/or battery systems. A multilayer phase change material composite structure may include multiple layers having different properties. For example, a PCM material composite layer may include a supporting structure having pores and a phase change material. Further, a layer of fire retardant material may be used in the multilayer phase change material. In some embodiments, additional layers such as coatings, thermal interface materials, and/or high thermal conductivity material may be present. A matrix formed from a porous supporting structure and a phase change material may be used to control and/or dissipate heat in a thermal management system. Support elements may provide stability. The thermal management system may mitigate conditions that could lead to a thermal runaway event and/or may influence conditions within the system during a potential thermal runaway event to reduce risk of fire. The thermal management system may include water, flame- and/or fire-retardant materials to control temperatures of an energy storage device and/or system. A housing may be used to surround a portion of a heat generating device such as an energy storage device or system, for example, an individual battery or a group of batteries, respectively. The housing or enclosure may include interior structures that surround and in some cases electrically isolate batteries from a thermal sink that includes a porous flame- and/or fire-retardant material having water in the pores.

Methods of using an integrated scraper-sponge having a scraper layer with and edge and fixed between the first and second sponge and/or abrasive layers. The scraper sponge is wetted and applied to a surface that is contaminated. The scraper-sponge is moved about the contaminated surface or dabbed onto the surface. The wet sponge portion loosens residue while the scraper edge scrapes residue from the surface as the scraper is moved about the contaminated surface.
