Definitions

• the invention relates to a method for producing molded parts, in which certain textile residues are mixed with an adhesive and held in a mold under pressure until the adhesive has set.
• a method for producing molded parts is described, for example, in EP-B-0 160 270.
• the various options for the construction of such materials are also discussed there.
• Tearing wool, wood, shavings and torn paper residues are mentioned as fibrous starting materials.
• polyester fibers residues from the processing of synthetic fibers, in particular fibers made of polyethylene terephthalate, generally referred to as polyester fibers, which are used in the form of tearing wool.
• molded parts such as e.g. Particle boards common, as well as pressed foamed materials, including insulation and insulation materials made of, for example, fibrous inorganic material.
• Textile fabrics such as woven or knitted fabrics based on polyester / cotton blends, such as polyester / cotton 65% / 35%, of polyester / wool blends, such as polyester / wool 55% / 45%, may be mentioned by way of example Polyesters such as polyethylene terephthalate, cotton, wool, acrylic, viscose or mixtures of these types. It is also known that insulation materials, such as waiting, are also produced from such materials. Textile processes such as those that lead to the formation of nonwovens are used.
• the present invention provides a further possibility of reducing and avoiding residues based on fiber materials.
• a method according to claim 1 is provided, by means of which such textile products, even after intended use, can be used to build moldings, such as insulation and insulation materials, which, if desired, can also have supporting, at least self-supporting properties.
• the textile residues to be used include, in particular, textile surfaces such as woven fabrics, knitted fabrics, knitted fabrics, scrims, nonwovens.
• the shredded material is intimately mixed with an adhesive or binder, preferably as introduced in construction and living areas.
• Preferred adhesives are common and imported products from other fields of work, the working temperature of which is below the melting temperature of the fiber materials used.
• powdered adhesives are particularly suitable.
• reactive adhesives can also be used. The choice of adhesive is not subject to any restrictions with regard to chemistry.
• Thermoplastics which are liquefied by heating and which, after cooling, join the fibrous material, are particularly preferred.
• the amount of adhesive is selected according to the intended use, after which the smallest possible amount of adhesive is aimed for.
• the amount of adhesive is preferably not more than 10% by weight.
• the mixture of textile products and glue is evenly distributed over the subsequent m2 weight and heated in a press until the glue is fully effective.
• the thickness of the formed part follows from the distance between the plates. Pressure relief takes place when the adhesive has developed its adhesive strength to such an extent that no change in thickness occurs after relief. This is the case for hot melt adhesives below a certain temperature.
• composition of the textile material is based on textile-proven mixtures that are common in the consumer and home textile sector.
• Preferred examples of such mixtures are residues from Polyester / cotton 65% / 35%, polyester / wool 55% / 45%, acrylic / wool blends, or 100% use of polyester cotton, wool, acrylic, viscose.
• the molded parts available in this way can be used in particular as insulation and insulation materials and have known textile properties. This affects e.g. moisture absorption, dimensional stability, temperature behavior and the like. Like the corresponding textile products, these insulation and insulation materials are comparable insulating, permeable to air and moisture. Typically, as with the corresponding textile products, heat-insulating, temperature-compensating and sound-insulating properties are combined with one another.
• molded part is to be understood to mean plate-shaped material, as are products to which a specific shape is stamped, in accordance with the later use.
• Such insulation and insulation materials are usually flexible, self-supporting and can be cut. They also take on load-bearing functions when the setting is tight, which means that they can be subjected to mechanical loads in addition to absorbing their own weight.
• a decorative surface can optionally be provided with a final, for example with a decorative surface.
• a decorative surface will preferably be based on textile products, such as with the use of nonwovens, fabrics, knitted fabrics, scrims.
• a waterproof, vapor-permeable surface is preferred, as is common with conventional mineral insulation materials, for example.
• One-sided surface covering will preferably serve to convey an additional property, such as modification of the decoration of the surface and / or its impermeability to water, while double-sided surface covering can make a significant contribution to the stiffening of the product.
• a special type of product stabilization is possible if, for example, a scrim or woven grid stabilizes the interior of the insulation and insulation material approximately in the middle. In this case, the formability of the material is not affected as is the case with surface stabilization.
• the adhesive can be used to impart to the moldings according to the invention, such as insulation, insulation and carrier materials, further functions which are desired for the intended use of these moldings.
• impregnating properties (water-repellent character) of the molded parts can be imparted with additives in the adhesive.
• additional properties can also be generated by subsequent treatment or by introducing separate components into the premix.
• a surface design by spraying for example a dye, is also possible.
• Such products can be used as insulation and insulation material in construction, also in mechanical engineering, as insulation and anti-drumming material, if desired in combination with a self-supporting character, or even mechanically resilient.
• the preferred area of application is insulation and insulation in residential construction, where well-known, proven combinations of textile properties are transferred to the building industry. Processing is easy, since these insulation and insulation materials can at least be self-supporting due to the way they are manufactured.
