Abstract

A coated material (104) with a carrier (6) on a sports glove (100) has a first functional layer made of a polymer resin with thermally expanding microspheres (7) that are not yet expanded. A second polymer resin layer without thermally expanding microspheres (8) is applied to the first layer and serves as an adhesion promoter between the first and third layers. The third top layer comprises a hot-melt adhesive film (8) that creates a virtually inseparable bond between the coated material (104) and the sports glove (100).

Description

The present invention relates to a new material produced by coating and intended for sports gloves, in particular goalkeeper gloves. It further relates to the method for producing the new material, its use, and a sports glove comprising the material. State of the art Many synthetic materials produced by coating—a process in which thin layers of materials in liquid or powder form are applied to a substrate—with polymer resins or dispersions are typically applied to a carrier material. These materials are based on a carrier material of paper, nonwovens, or textiles coated with one or more layers of polymer resins or dispersions. In these materials, the carrier is made of acrylic or polyurethane resins or polymers in aqueous dispersion or as a solution in organic solvents. Application can be direct, by spreading the prepared medium onto the carrier material. Alternatively, the medium can be applied indirectly, by applying the prepared medium in a not yet fully cured state to a non-adherent, smooth, or textured carrier and then transferring it to a second, adhesive carrier by simple contact. In the case of indirect coating, a textured carrier material can also influence the surface of the substrate's top layer. Both variants are subsequently thermally cured in a drying tunnel. These processes are widely known and used. However, this has the disadvantage that the material produced in this way then has to be cut in a further process using elaborate, and especially expensive, cutting tools and then attached to the sports glove using a further joining technique, especially sewing. Furthermore, products are known in the industry that can be applied directly to sports gloves as printing pastes. These involve processing a polymer resin with appropriate additives into a foam. This substrate is then transferred directly onto the sports glove using stencils. However, handling these printing pastes is very difficult, as they have a limited shelf life during the production process and only adhere to the textile after a complex drying process. Adhesion to porous surfaces, especially foams, is also very difficult to achieve, as the printing paste is at least partially absorbed by the surface and cannot form a sufficient bond with the surface of the sports glove. The industrial products manufactured in this way are generally used as foams or laminates in the sports glove industry on a cotton or polyester backing to modify the abrasion resistance, impact absorption or slip resistance of the surfaces of sports gloves. Task The object of the invention is to provide a material for a sports glove, in particular a goalkeeper glove, that improves the abrasion resistance, cushioning or slip resistance of a sports glove. According to the invention, this problem is solved by the features of claim 1. The coated material for a sports glove, comprising a carrier, comprises according to claim 1 a) a layer of polymer resin, characterized in that the resin comprises thermally expanding microspheres. b) a second layer of polymer resin, characterized in that the resin does not comprise thermally expanding microspheres. c) a top layer, characterized in that the layer comprises a hot melt adhesive film. According to the invention, the coated material for a sports glove comprises, in addition to an abrasion-resistant, cushioning and/or anti-slip polymer resin layer with thermally expanded microspheres and a polymer resin layer without thermally expanding microspheres, which acts as an adhesion promoter between the first layer of polymer resin with thermally expanded microspheres and the third cover layer of hot melt adhesive film, a third layer of hot melt adhesive film which can create a connection between the coated material and the sports glove in order to protect the sports glove from external mechanical influences and/or the hand of the wearer of the sports glove from external mechanical forces and/or slippage inside the sports glove. Advantageous designs and further developments result from the claims dependent on claim 1. Polymer resins are particularly well-suited for this application because their different chemical compositions allow them to be tailored to the specific requirements of any sports glove. To meet the ergonomic principles of lightweight sports glove construction, the material according to the invention provides the functional layer of polymer resins with thermally expandable microspheres, which are expanded only in the final process step, simultaneously with the fixation of the coated material to the sports glove. In contrast to existing inventions, the coated material remains unexpanded until the final process step, thus representing a significant advantage in the manufacturing process, as the coated material has an almost unlimited shelf life. Furthermore, no complex tools or templates are required to fix the material to the sports glove at the desired extent. The fixing of the coated material onto the sports glove and th
