Provided are MOF-fabric composites having a crystalline MOF adhered directly to fibers of the fabric and methods of making MOF-fabric composites. A solution is adsorbed onto a fabric. The solution can include a metal salt, a linker, and a solvent. The solution is adsorbed onto the fabric and the fabric suspended over a heated vapor. The vapor releases onto the fabric, causing the metal salt, the linker, and the solvent to diffuse out of the polymer fibers. The linker links metal from the metal salts to form crystals attached to the fabric, and the vapor aids crystallization.

A composition to be used for providing permanent hydrophilic finishing of textile fibers and textile products made thereof consists of at least one anionic surfactant based on a neutralized phosphoric acid ester of a fatty alcohol having at least 12 C-atoms in a proportion of 25 to 80 weight percent, a non-ionic consistency enhancer in a proportion of 10 to 50 weight percent, a hydrophilically modified polyalkylsiloxane in a proportion of 3 to 35 weight percent and a hydrotropic dispersion additive in a proportion of 0 to 5 weight percent, each based on the total weight of the composition. The composition is preferably present as a granulate and has a melting point of at least 45° C.

This invention relates to a floor mat having reduced tuft profile on the backside of the textile component of the floor mat. The floor mat is comprised of a textile component and a base component. The textile component includes face yarn tufted through a primary backing layer. The reduced tuft profile is present on the backside of the textile component. Advantages of a floor mat with reduced tuft profile include improved uniformity of the secondary backing layer applied to the textile component and improved durability of the textile component.

A method is for preparing acrylic acid from β-propiolactone and for using β-propiolactone. The process is based on a specific reactivity of β-propiolactone whereby acrylic acid is formed under operating conditions that are mild, especially in terms of temperature.

A wrapping material having three distinct polymeric layers interfaced with a woven polymeric scrim is disclosed. A first polymeric layer is formed by extruding a first polymeric coating onto the scrim. A second polymeric layer and a third polymeric layer are simultaneously formed by co-extruding a second polymeric coating onto the scrim and a third polymeric coating onto the second polymeric coating.

Methods for the preparation of carbon fiber from polyolefin fiber precursor, wherein the polyolefin fiber precursor is partially sulfonated and then carbonized to produce carbon fiber. Methods for producing hollow carbon fibers, wherein the hollow core is circular- or complex-shaped, are also described. Methods for producing carbon fibers possessing a circular- or complex-shaped outer surface, which may be solid or hollow, are also described.

Methods to increase structural performance, strength, and durability of textile-reinforced composite materials are provided. The textile reinforcement may be knitted, for example, in a flat bed weft knitting machine. The method may include pre-stressing a textile reinforcement preform by applying tension. A polymeric precursor may be introduced to the pre-stressed textile reinforcement preform. The polymeric precursor may then be cured or consolidated, followed by releasing of the applied tension to form the composite article comprising polymer and the pre-stressed textile reinforcement. In other aspects, a composite article is provided that has a pre-stressed textile reinforcement structure and a cured polymer. The textile reinforcement may be a knitted, lightweight, seamless, unitary structure. The knitted reinforcement structure may have distinct first and second knitted regions with different levels of pre-stress, thus providing enhanced control over strength, rigidity, and flexibility of the composite article.

The invention relates to a space frame radome comprising a sheet, said sheet comprising high strength polymeric fibers and a plastomer, wherein said plastomer is a copolymer of ethylene or propylene and one or more C2 to C12 alpha-olefin co-monomers and wherein said plastomer has a density as measured according to ISO1183 of between 860 and 940 kg/m.sup.3 and wherein the sheet has an areal density that is with at most 500% higher than the areal density of the high strength polymeric fibers.

A flame retardant composition containing a phosphorous containing ammonium salt, a crosslinker, and water is provided, and its application to yarn or fabric to provide a flame retardant yarn or fabric. In a preferred embodiment, the yarn or fabric is made from a polyurethane elastomer, such as a spandex. A method to prepare the flame retardant composition and apply it to the fiber or yarn is also provided.

The present invention relates to a composition, textile, and mask for reducing the inhalation of pollutants. The composition includes an aqueous solution of an inorganic iodide compound, a metal phthalocyanine, and a polymeric binder. The inorganic iodide can be cuprous iodide, the metal phthalocyanine can be iron phthalocyanine, and the polymeric binder can be polyvinylpyrrolidone or polyvinyl alcohol. This pollutant-inactivating composition neutralizes pollutants such as nitrogen dioxide, sulfur dioxide, ozone, volatile organic compounds and other unpleasant airborne agents, without requiring elevated temperatures or bulky canisters containing adsorbents. Optionally, a humectant can also be incorporated into the coating solution to retain moisture in the active filter matrix, which enhances the activity of the composition to inactivate oxidizing gases and other toxic constituents of air pollution.
