Abstract:
The invention relates to a method for producing a textile composite, especially for outdoor applications, which contains at least one layer (2) of polymeric nanofibers deposited on a textile carrier layer (3), in which at least one hydrophobic agent in a liquid or plastic state is applied with plasma spraying to the textile carrier layer (3) after deposition of the layer (2) of polymeric nanofibers and after connecting the two layers by a binder, whereby the hydrophobic agent is applied to the textile carrier layer (3) from the side opposite the side where layer (2) of polymeric nanofibers has been deposited. The invention also relates to a textile composite (1), especially for outdoor applications, which contains a layer (2) of polymeric nanofibers deposited on a textile carrier layer (3), prepared by this method.
Abstract:
Fabrics are treated with a hydrophobic treatment that includes at least one hydrophobic monomer and a crosslinker. The treatment is low in volatile organic compounds and water. It is a liquid at 22°C or a suspension having a phase that is liquid at 22°C. The monomer and crosslinker are cured in a free radical polymerization to form a hydrophobic coating on a fibrous substrate. The curing is performed by removing interstitial air from the fabric and then curing the fabric in a low oxygen environment without allowing it contact with oxygen or air from the time the interstitial air is removed until conversion of monomers reaches at least 50%.

Abstract:
Textile bodies may be coated by physical or chemical vapour deposition in the gaseous phase. The layers deposited on the fibres or filaments have a high quality. It is thus possible to coat filaments or fibres without leaving any pores even with very thin layers, which cause however an imperceptible increase of the total volume of the textile object. Because of the high mobility of the coating material particles, even critical spots, such as the chaining spots in meshed or woven goods, are reliably coated. The same is valid also for complex designed, three-dimensional textile shaped bodies. Besides coatings by simple deposition, surface polymerisations may also be carried out, forming impenetrable layers on the textile material, which either protects it against the environment (allergy, sensitivity to air or light) or confer new properties to it (electric conductivity, antiadhesive coating). Coating in the gaseous phase also prevents in many cases the textile body to be processed from drying out.

Abstract:
A treated carbon fiber tensile cord for use in power transmission belts, hose, tires or other reinforced rubber products and the resulting product, which includes carbon fibers which are coated with a polymeric layer deposited and polymerized at atmospheric pressure in a plasma assisted chemical vapor deposition process. A suitable polymeric layer is compatible with the intended matrix which the cord will reinforce. For a rubber belt, the coating is compatible with the rubber composition of the belt body or an adhesion gum or adhesive such as RFL which surrounds the cord. For RFL/rubber systems and cast polyurethane elastomers, a suitable polymer is the APP reaction product of a vinyl carboxylic acid or an ester or amide thereof. Suitable carboxylic acids include acrylic acid and methacrylic acid. Various esters and amides of vinyl carboxylic acid are also suitable, such as 2-hydroxyethyl methacrylate, N-isobutoxymethyl acrylamide, and N-hydroxyethyl acrylamide.
Abstract:
The invention relates to a chemical, mechanical and/or optical protective and/or diffusion barrier layer (16) disposed on a metal or plastic substrate (14). Said layer consists of an organic layer matrix (10) with metal-containing particles (12) dispersed therein said metal-containing organic layer (16) being plasma-polymerized starting from at least one hydrocarbon which can be substituted and one metal-containing component. The protective and/or diffusion barrier layer (16) is used in a thickness (d) in the submicron range and contains metal particles (12) finely dispersed therein, that have a grain size that lies below 50 % of the layer thickness (d). The organic layer matrix (10) is deposited by plasma polymerization from a process gas that comprises at least one hydrocarbon that can also be substituted and one metal-containing component and/or an inorganic gas in a reactor that can be evacuated. During the progression of the process organic monomers having different polarities and/or metal-containing components having different concentrations can be introduced into the reactor. The protective and/or diffusion barrier layer (16) is for example used as anticorrosive layer of metal substrates (14) or as a flexible diffusion barrier with an adjustable electroconductivity for plastic packagings. The inventive method is inter alia used for providing fibers, whiskers and rods with an electroconductive coating.
