This invention relates to tacky finishes and to the textile materials and articles treated with the tacky finishes. The tacky finishes provide improved processing features for end-use articles that contain such finishes. The tacky finish may be combined with other adhesion promotion finishes in the treatment of textile materials. The textile materials and articles may be used as rubber reinforcing materials, such as automotive tire cap ply, single end tire cord, carcass reinforcement and side wall reinforcement. End-use articles that contain the treated textile materials include rubber-containing materials such as automobile tires, belts, and hoses. This invention also relates to the methods for manufacturing the treated textile materials and articles.

A consumable filament for use in an extrusion-based additive manufacturing system, where the consumable filament comprises a core portion of a matrix of a first base polymer and particles dispersed within the matrix, and a shell portion comprising a same or a different base polymer. The consumable filament is configured to be melted and extruded to form roads of a plurality of solidified layers of a three-dimensional part, and where the roads at least partially retain cross-sectional profiles corresponding to the core portion and the shell portion of the consumable filament and retain the particles within the roads of the printed part and do not penetrate the outer surface of the shell portion.

Disclosed are improved polymer materials. Also disclosed are fine fiber materials that can be made from the improved polymeric materials in the form of microfiber and nanofiber structures. The microfiber and nanofiber structures can be used in a variety of useful applications including the formation of filter materials.

The present invention relates to a reinforced composite material and a method for its production. The composite material comprises at least one cured resin having a reinforcing material. Preferably the reinforcing material is a plurality of glass fibres which are treated such that the properties of the interphase substantially surrounding each fibre are substantially equivalent to those of the bulk cured resin. The fibre treatment may be selected from the group consisting of a polymeric coating, a hydrophilic surface coating, a surface coating of a free radical inhibitor, or a reduction in the total surface area of the fibres. The reinforced composite material of the invention provides improved long-term mechanical properties compared to traditional glass fibre reinforced materials.

The general inventive concepts relate to unbonded loosefill fiberglass compositions useful for insulation. The compositions demonstrate improved product density. In certain instances, this is accomplished by application of a surface modifying agent.

A reinforcement means for molded and extruded articles such as tires has a metal structure with a layer of silica gel bonded thereto. The silica gel bonds the reinforcement means to the rubber compound during the molding/vulcanization of the rubber compound without the need for a slow curing stage. The silica gel may be applied to the metal structure by a sol-gel process with the gel formed by drying the sol at a temperature up to 150 C. The reinforcement means is preferably a cable formed from steel wires coated with the silica gel. To further improve bonding of the silica gel to the rubber compound, an organosilane bonding agent may be included in the rubber compound or the reinforcing means provided with a second layer comprising an organosilane as a bonding agent. The reinforcement means are particularly useful for strengthening and providing geometric stability to tires.

A yarn or multi-fiber formed of a plurality of micron diameter stainless steel monofilaments which have been rendered more conductive by one or more coatings of electrolytically-deposited metal or metal alloy materials. The metallized yarn provided by the invention has a very low electrical resistance, with consequent benefit in electrical performance, and is particularly useful as an RFI/EMI shielding material.
