Definitions
- the invention relates to a trim for its application as an interior coating of vehicle roofs, being self-supporting and being formed by several layers, which, with the exception of one of them, act as a support for the trim, and the other as a decorative outer layer .
- the set of the three layers is a sandwich with good stiffness properties so that the set is self-supporting.
- the interior lining of the roofs of vehicles generally requires the use of a trim material that is self-supporting, easily adapts to the various shapes of the different roofs, provides a reduced weight as a whole and also presents an exterior look and feel pleasant, also requiring good sound absorption properties to promote interior comfort.
- the use of multimaterial trimmings is usually used, in which the various materials are arranged in layers of reduced thickness, joined by adhesive, in such a way that each one contributes its properties to the formed set or sandwich.
- a widely used configuration is usually formed by a first layer, in the area of contact with the ceiling, composed of a lining material, to which a second layer formed by a grid or mesh based on glass fibers adheres, fixing between both layers by means of adhesive.
- a first layer in the area of contact with the ceiling, composed of a lining material, to which a second layer formed by a grid or mesh based on glass fibers adheres, fixing between both layers by means of adhesive.
- the set of the three layers of polyester fibers is a sandwich with good stiffness properties that allows the trim to be self-supporting and meet the requirements of vehicle manufacturers, resulting in optimal properties in terms of acoustic behavior.
- the novelty of the invention lies in the composition of the three "support" layers in the simple process of manufacturing the trim achieved with those materials, since being the layers of polyester fibers the final product obtained can be considered as a single component.
- the decorative layer is also usually made of polyester, with the advantage that the trim as a whole can be easily recycled, while removing the layers of adhesive that are required in the traditional trim to fix the different layers to each other which constitute the support structure.
- the process of obtaining the trim is based on a preheating of the three "support" layers and at the same time a molding of said support with the decorative layer, until obtaining the final shape of the trim.
- polyester fibers that constitute the layers of the support structure of the trim, according to the invention are of the type called "short".
- polyester fibers in question two of them are equal to each other and with a composition of 100% short hot melt polyester fibers of low melting point, while the third layer, which is interspersed between the two Previously, it is of considerable greater thickness and, although it is constituted on the basis of polyester fibers, it has a different composition since low melting hot melt fibers, solid fibers and hollow fibers can be used, in different proportions and with different characteristics.
- This layer is made in the usual way to manufacture wadding or nappa for stuffing garments or fillings in the furniture industry, giving the final trim an excellent acoustic absorption behavior. These layers have a greater or lesser weight, depending on the maximum final thickness required for the trim.
- the trim of the invention includes a thick central layer (1), composed of several types of short polyester fibers, such as hot melt fibers, solid fibers and hollow fibers.
- a thick central layer (1) composed of several types of short polyester fibers, such as hot melt fibers, solid fibers and hollow fibers.
- These three layers constitute what is called the "support” structure, which is complemented by the decorative layer with a pleasant look and feel, which consists of a layer of light fabric (3), or another suitable material, which depending on its composition you will need in some cases of fusible film or additional adhesive (4).
- the joining of the layers (1) and (2) together is done by preheating the assembly, at a temperature that melts the low melting hot melt fibers in which these layers (1) and (2) are constituted, achieving that all of them remain attached to each other and therefore jointly united.
- the outer or decorative layer (3) is added, molding the assembly below the melting temperature of the fibers, thus obtaining a roof trim that remains solid as a monocomponent element, with the final shape required.
- the weight of the central layer (1) will depend on the thickness required for the trim that is intended to be obtained, while the weight of the layers (2) will be smaller and will depend on the mechanical and thermal requirements of the final product.
