A composite textile is provided. The composite textile includes a textile substrate and a thermal material layer formed on the textile substrate. The thermal material layer includes a nanocomposite powder. The nanocomposite powder is composed of a pyrrolidone-containing polymer and an inorganic particle. The pyrrolidone-containing polymer is polyvinylpyrrolidone, a derivative of polyvinylpyrrolidone or a combination thereof. The inorganic particle is a metal oxide composed of a first metal M.sup.A, a doping metal M.sup.B and oxygen. The inorganic particle makes up 62.5-99.9 wt. % of the nanocomposite powder.

A heat insulation sheet includes a fiber sheet, a resin layer provided on a surface of an outer peripheral portion of the fiber sheet, and a silica xerogel disposed in spaces of the fiber sheet. The fiber sheet includes fibers forming spaces among the fibers. The resin layer is denser than the fiber sheet and made of thermoplastic resin. The silica xerogel is held in the plurality of fibers. This heat insulation sheet is excellent in adhesiveness, and is easily attached to a protective sheet or a frame to be fixed.

A heat insulator is provided that has a coating structure preventing separation of silica aerogel in a composite sheet. The heat insulator includes: a composite layer having silica aerogel enclosed in a nonwoven fabric; and a coating film containing a hydrophilic resin and a lipophilic resin and coating a surface of the composite layer. The nonwoven fabric resides in the coating film. In the coating film, the heat insulator includes the lipophilic resin which is present in the hydrophilic resin in the form of a plurality of islands.

A composite hydrophobic insulation textile with glass fibers and a first fluoropolymer. The first fluoropolymer and the glass fibers are interspersed with one another with sufficient uniformity to render the composite hydrophobic insulation textile as hydrophobic insulation and is temperature stable up to 600 degrees Fahrenheit.

Hydrophobic thermal insulation fiberglass flexible blanket using a textile grade fiberglass is produced by impregnating a hydrophobic polymer (e.g. a fluoropolymer) dispersion into a fiberglass blanket/mat, such as a needle felted fiberglass (FG) blanket/mat. The preferred FG needle felt blanket is a mechanically, rather than organically, bound glass fiber insulating blanket. The hydrophobic polymer dispersion forms a hydrophobic coating on the surface of the fiberglass filaments. Integral hydrophobicity is achieved and maintained without the need to add commonly-used hydrophobic inorganic particles, such as treated silica aerogels or fumed silica. Optionally, to enhance overall hydrophobicity and to inhibit fibrous surface lofting, a super-hydrophobic coating of fluoropolymer and inorganic particles such as silica particles may be dispersed onto one or more surfaces of the blanket. The resulting blanket thermally insulates better than mineral wool; it is equal in insulating properties to (or is slightly better than) untreated FG mat; and it slightly less insulating than aerogel-based blanket materials. It is relatively inexpensive to manufacture, it is flexible, it is durable, it can optionally be made moldable, it eliminates dust, and it remains hydrophobic after long-term heating to 600 F. (315 C.), or after short-term excursions to temperatures as high as 700 F. (370 C.).

A contact cool feeling (Qmax) of the front face (6) of the skin material (1) is 0.30 W/cm.sup.2 or less both before and after a heat treatment for 2400 hours at 70 C.

The present disclosure generally relates to polymer-aerogel/fiber composite materials, polymer-aerogel/textile composite materials, and systems and methods for producing them. The gel material can comprise, in some embodiments, a network of polymer. The fiber and/or textile material can comprise at least one of any natural, synthetic, and/or mineral fiber. In some cases, certain combinations of materials, solvents, and/or processing steps may be synergistically employed so as to enable manufacture of materials suitable for use in apparel, soft goods, and other consumer applications which may benefit from the properties of a polymer-aerogel/fiber composite and/or the polymer-aerogel/textile composite.

Disclosed are a sound absorbing fabric with improved thermal insulation, and a method of manufacturing the same, wherein an inorganic aerogel powder and a thermosetting binder resin are impregnated into a non-woven fabric made of a heat-resistant fiber, wherein the inorganic aerogel powder has a surface modified by a surfactant to be uniformly mixed with and dispersed in a binder resin, thereby forming the sufficient number of micro cavities inside the non-woven fabric and increasing dispersibility of the inorganic aerogel powder, and thus heat resistance, sound absorbing and sound insulating properties, and thermal insulation properties can be significantly improved.
