Abstract: The method for the treatment of mineral fiber, mineral fiber wool and mineral fiber flat structure with improved textile characteristics under use inorganic synthetic fiber, fiber wool, fiber surface of mineral raw materials such as slag-, rocks-, glass-, quartz or ceramic fiber that are produced based on metallurgical and nonmetallurgical slag and melt of natural rock by centrifugal process, nozzle blasting process or nozzle drawing process, comprises removing solid impurities such as slag particles from the fiber. The method for the treatment of mineral fiber, mineral fiber wool and mineral fiber flat structure with improved textile characteristics under use inorganic synthetic fiber, fiber wool, fiber surface of mineral raw materials such as slag-, rocks-, glass-, quartz or ceramic fiber that are produced based on metallurgical and nonmetallurgical slag and melt of natural rock by centrifugal process, nozzle blasting process or nozzle drawing process, comprises removing solid impurities such as slag particles from the fiber, where basalt-stone fiber, basalt stone fiber wool or basalt stone fiber surface are used as fiber. A mechanical crushing device used in the form of hammer mill or flail mill for separation is used for removing solid impurities. The intensity of the separation process is determined by a blow element, whose number, mobile arrangements and/or the centrifugal forces are determined. The mobile blow element is formed as spherical shaped designs, which influence in dependence with the rotational speed on the mineral fiber and mineral fiber surface to be cleaned. The treatment of the mineral fiber, mineral fiber wool or mineral fiber surface is carried out by the mobile blow element for increasing fiber volume, for reducing the brittleness and improving the textile characteristics of the mineral fiber. The treatment process is arranged directly or indirectly to the respective mineral fiber production process. The mineral fiber, mineral wool or mineral fiber surface is produced in a single- or multi-stage injection beam devices for the treatment, and the injection beam standing under pressure impinges with corresponding process medium such as fluid, gas or fluid or gas mixture on the mineral fiber materials to be treated. The treatment process is connected with a separation of the slag particles from basalt stone fiber wool and its filtration in corresponding filter plant. The process parameter is adjusted so that the impurities to be separated are formed in the form of solid materials and are integrated into the mineral fiber surface. The mineral fiber, the mineral fiber wool or the mineral fiber surface to be treated is applied on a porous, water-permeable auxiliary area such as injection beam reinforced fleece web and the impurities are filtered through auxiliary surface with the injection beam treatment. The mineral fiber, the mineral fiber wool or the mineral fiber surface to be treated is selectively treated in the auxiliary area by the separation process and the textile auxiliary area remains for surface stabilization in the composite materials. The partially processed auxiliary area is soldered after the treatment process by the mineral fiber area and the process is connected with a surface enlargement or surface structuring. Pathogen, fibrogen or carcinogenically effective fiber dust is bound through the effective injection beam by injection beam treatment and is processed in mineral fiber area. The mineral fiber, the mineral fiber wool or the mineral fiber area to be treated is injected in the filtering plant of the injection beam plant. The fiber dust is used as binding fiber for the reinforcement of the mineral fiber surface and for improving the area volume. The influential injection beam guides for the reduction of brittleness and for improving the softness of the mineral fiber materials to be treated. The adhesion and fixing of the fiber components are carried out in blended yarn through the effect of temperature or temperature and pressure before, during or after the processing to mineral fiber hybrid yarn. The mineral fiber hybrid yarn is mixed to shrinkable and meltable fiber component, which guides through the temperature effect or temperature and pressure effect before, during or after the yarn production. Independent claims are included for: (1) a method for the production of padded or stitched textiles with improved stability characteristics and reinforced cushion effects; (2) a method for the production of mineral fiber hybrid yarn with improved stability characteristics and yarn volume; (3) a method for the treatment and production of high temperature stable mineral fiber/mineral fiber surface product; (4) a cleaned mineral fiber, mineral fiber wool and mineral fiber surface product; (5) a surface-stabilized ceramic insulation composite; (6) a mineral fiber hybrid yarn (7) a textile surface product; and (8) a basalt stone fiber surface reinforced composite.
