Layered, and optionally dispersible fibrous structures containing fibrous elements that exhibit inter-layer voids between two or more layers within the fibrous structures, sanitary tissue products employing such layered, optionally dispersible fibrous structures, and methods for making same are provided.

A display device including a folding area includes a display panel, a cover window disposed above the display panel, and a protective film disposed on the cover window, where the protective film includes a first region and a second region including a same material as each other and having different moduli from each other. A modulus of the second region of the protective film is less than a modulus of the first region, and the second region is disposed in the folding area.

A unitary floor comprises a top layer, floor components, and a bottom layer. The floor components are sandwiched between the top layer and the bottom layer to provide an integral structure that comprises a continuous surface, unitary floor. Each of the floor components has a material strips. Moreover, the material strips that make up a corresponding floor component is a composite assembly that includes a first set of material strips, which may be interleaved with a second set of material strips. The first set of material strips includes a different density compared to the second set of material strips. Moreover, the unitary floor may be fabricated by a vacuum process, such as a vacuum infusion process.

A treat-insulation material, includes: a first substrate layer that includes an aerogel and first fibers; and a second substrate layer that is layered on the first substrate layer and that includes an aerogel and second fibers, wherein a volume density of the aerogel in the first substrate layer is larger than a volume density of the aerogel in the second substrate layer, and an amount of the aerogel that is present around a first surface of the second substrate layer inside the second substrate layer, not adjacent to the first substrate layer, is smaller than an amount of the aerogel that is present around a second surface (inside the second substrate layer adjacent to the first substrate layer.

Fabrics made for apparel, tents, sleeping bags and the like, in various composites, constructed such that a combination of substrate layers and insulation layers is configured to provide improved thermal insulation. The fabric composites are constructed to form a radiant barrier against heat loss via radiation and via conduction from a body.

A method of manufacturing a polymer film includes melting a resin, extruding the melted resin through a die to produce a polymer film, shaping the polymer film, cooling the polymer film, illuminating a surface with a light source, capturing an image of a shadow cast by the polymer film on the surface while the polymer film is between the light source and the surface, calculating a frequency spectrum of at least a portion of the captured image, and adjusting a process parameter of the melting, the extruding, the shaping, or the cooling based on the frequency spectrum.
