Description

metal material

The present invention relates to a composite comprising at least one flexible textile fabric, preferably a net-like knitted fabric, and at least one metal foil, comprising an adhesive layer between the flexible textile fabric and the at least one metal foil, the use of this composite and a method for its production.

Fabrics that reflect the light and thus bring about a unique aesthetic effect are of great interest to the fashion industry in particular. However, the production of such a fabric which retains its textile properties (such as flowability, washability, robustness, ironability) while still being inexpensive to manufacture presents a challenge.

From EP 0 773 795 A2, for example, a flexible, refractory and decorative laminate is known. Here, a thin aluminum foil is bonded directly to a polyvinyl fluoride film to increase the ability of the aluminum foil to adhere to an underlying paper-like layer. In this case, the wrinkling, which often occurs when using aluminum foil is minimized. In addition, a transparent polyvinyl fluoride layer is applied to the other side of the aluminum layer to increase the durability of this (later visible and thus decorative) layer. The resulting laminate is used for cladding aircraft interiors. Such a laminate therefore shows no textile properties, as defined in particular above.

From DE 3 213 006 A1 a game protection cuff is known, which comprises a fabric made of glass fibers, in which aluminum foil can be woven. As a result, a reflective effect can be generated, which deters game and thus prevents game attack on young plants. However, such a fabric is less robust. Since the aluminum foil is merely woven, it is not firmly and permanently connected to the fabric itself and therefore can not be washed, for example. Also, the flowability of the described tissue is not sufficient. DE 29 6056 221 U1 describes a seat cushion, which is constructed from different layers and thereby has an aluminum foil layer as a barrier layer. This layer should in a fire exposure to a passage of molten or softened plastic, which is at least one other layer of the seat cushion, avoid in the direction of the fabric, thereby further burning of the seat cushion is avoided. This layer is thus robust, however, the aesthetic appearance of the aluminum layer, in particular the light reflection, is not used in normal use, since the layer is located inside the pad.

EP 0 886 031 A1 describes a protective system for building openings, such as windows, which has a planar fiber material with a metallization. The flat fiber material may also be a knitted fabric. Here, the permeability of the protection system for air, sun rays and insects in the foreground. In this case, this document describes exclusively in relation to the known prior art that it is known to laminate flat textiles with aluminum foil together. However, since the protection system should be permeable to air, such a composite is considered disadvantageous. Similar systems are described in EP 0 900 909 A1.

From DE 3 508 940 A1, a laminate of a reinforcing mesh layer of thermoplastic strands and an aluminum foil is known. The network layers disclosed here, however, are exclusively network structures which can be obtained by extrusion of said strands and not around knitted fabrics. The resulting laminates are used as toweling material. In addition, the joining of the network structure with the aluminum foil via hot bonding and pressure sealing takes place. Therefore, in this laminate, the flowability and optical decorative aspects of the resulting laminate are less prominent. In addition, the production is complicated and thus associated with increased costs.

DE 19 20 917 A discloses the bonding of textile materials with rubber and in particular adhesives which are suitable for the bonding of textile materials with rubber. A suitably specified adhesive is characterized by a latex of a polycarboxylated styrene / butadiene copolymer and components necessary to form a phenol / formaldehyde resin.

DE 10 2012 108 994 A1 describes a method for producing a decorative wall or ceiling lining, comprising the gathering of at least one partial area of a light metal foil to at least one elevation and the attachment of this shirred light metal foil to a wall or ceiling to be decorated. Based on this prior art, the present invention was based on the object to remedy at least one, preferably all the disadvantages of the prior art. In particular, the object of the present invention was to provide a substance which combines good textile properties with a favorable production process. The resulting fabric is said to provide ease of handling, particularly in terms of fluidity, which is very similar to that of a "normal" fabric (such as cotton), and the resulting fabric should be able to reflect the light to provide aesthetic design possibilities It should also be very sturdy, however, the fabric should not be substantially transparent and thus be able to be used, for example, to form garments that cover the underlying body.

These objects were achieved by providing the composite according to the invention, its use and a process for its preparation.

It has surprisingly been found that the composite of the present invention has good textile properties. In this case, the term "textile properties" is preferably understood to mean at least one property, preferably all properties, which are selected from the group consisting of the flowability, the washability, the robustness, the ironability, the processability and the suturability Flowability thereby preferably means the ability of a textile material to conform to a fit (for example a T-shirt to a torso) .The composite according to the invention can be produced inexpensively Cotton, to be handled. In this case, the composite according to the invention has an excellent aesthetic effect, since it is able to reflect the light. In particular, when the fabric according to the invention has wrinkles and / or creases, its ability to diffuse the light differs into a particularly beautiful aesthetic effect.

In this case, the composite material according to the invention is robust. In particular, it is difficult to break. Thus, its properties differ significantly from the properties of normal metal foil. This is usually very sensitive and in no way tear-resistant. The composite according to the invention reinforces the metal foil in such a way that the tensile strength is significantly increased. In particular, the composite according to the invention can be washed. In this case, a cleaning in a conventional washing machine, preferably at 30 ° C an automatic program is possible. Thus, the composite according to the invention is not only for art objects of interest, but in particular also suitable for everyday use. In particular, this can be attributed to the fact that the metal foil is substantially flatly reinforced via the adhesive layer with the netlike knit and / or the nonwoven fabric. In this case, the adhesive layer preferably directly adjoins the metal foil at each point and / or directly to the net-like knit (the individual threads of the net-like knitted fabric, ie directly to the net structure of the knitted fabric) and / or the nonwoven fabric. It is thus particularly preferable that the composite according to the invention at no point has no additional layer, in particular no air (inclusions), between the adhesive layer and the metal foil and / or the threads of the netlike knit or the nonwoven fabric. The metal foil is therefore preferably connected at any point via the adhesive layer indirectly with the net-like knit and / or nonwoven fabric and / or in contact.

Also, the composite of the invention can be sewn. As a result, in particular a seaming of the composite material according to the invention is possible. Also, the composite of the invention can be processed into garments or the like. The composite of the invention is substantially non-transparent, so that it can be readily used to make common garments. Likewise, a combination of the composite material according to the invention with other substances, if appropriate also transparent substances is possible to produce corresponding objects, preferably garments. Such a combination also increases the breathability of the resulting object. The substance according to the invention comprises a metal foil. Preferably, this metal foil is a light metal foil. All embodiments of the present invention are thus preferably configured with a light metal foil. Such light metal foils are known in the art. Such a light metal foil preferably has a thickness of 0.001 to 0.5 mm, particularly preferably 0.004 to 0.02 mm, very particularly preferably 0.010 to 0.15 mm. It has been found that the flowability of the resulting composite is particularly good if the light metal foil does not exceed a thickness of 0.02 mm. The light metal foil preferably comprises aluminum and, in the case of films, usual alloying additives. The light metal foil preferably consists of aluminum and, in the case of films, conventional alloy additives. It is known that in the production of aluminum foil, especially when it is rolled very thin, the film webs are doubled for reasons of efficiency, so put on each other. As a result, only the outer sides of the rollers are polished. The overlapping sides do not come into contact with the rollers and remain dull. More preferably, in the composite of the invention, the polished side of the light metal foil is oriented so that it does not come in contact with the adhesive layer (the matte side of the light metal foil is bonded to the adhesive layer). For decorative reasons, it may also be possible to use a combination of different composite materials according to the invention, in which partially the matt and partly the polished side of the light metal foil is oriented towards the adhesive layer.

Preferably, the metal of the metal foil is selected from the group consisting of aluminum, gold, silver, platinum, copper, any alloys of the aforementioned metals, such as bronze or brass, and any combination of the aforementioned metals.

In one embodiment, the metal of the metal foil is gold or any alloy thereof. In particular, this is gold leaf. This can be known to have different carats numbers and / or colors. For example, different colors of the films such as pink gold foil or white gold foil can be used to impart a corresponding color to the composite according to the invention. Likewise, aesthetic accents can be set by combining different colors. Preferably, the gold foil has a thickness of 1/10000 to 1 mm, more preferably 1/9000 to 0.5 mm, further preferably 1/5000 to 1/3000 mm, most preferably of 0.010 up to 0.15 mm. This thickness is particularly preferred in order to achieve good property combinations of the composite according to the invention.

In another embodiment, the metal of the metal foil is silver or any alloys thereof. Preferably, the silver foil has a thickness of 1/10000 to 1 mm, more preferably 1/9000 to 0.5 mm, further preferably 1/5000 to 1/3000 mm, most preferably from 0.010 to 0.15 mm. This thickness is particularly preferred in order to achieve good property combinations of the composite according to the invention. In another embodiment, the metal of the metal foil is platinum. Preferably, the platinum foil has a thickness of 1 / 10,000 to 1 mm, more preferably 1/9000 to 0.5 mm, further preferably 1/5000 to 1/3000 mm, most preferably from 0.010 to 0.15 mm. This thickness is particularly preferred in order to achieve good property combinations of the composite according to the invention.

In another embodiment, the metal of the metal foil is copper. Preferably, the copper foil has a thickness of 1 / 10,000 to 1 mm, more preferably 1/9000 to 0.5 mm, further preferably 1/5000 to 1/3000 mm, most preferably from 0.010 to 0.15 mm. This thickness is particularly preferred in order to achieve good property combinations of the composite according to the invention.

In one embodiment, the composite of the invention may also contain any combination of metal foils. As a result, in particular, aesthetic effects can be achieved.

Furthermore, the composite according to the invention comprises a net-like knitted fabric. The person skilled in a knitted fabric is known. This is preferably a flat system of threads in which a thread loop is looped into another. The result is preferably a honeycomb, hexagonal structure of the threads. In particular, two warp threads are twisted after each weft so that a new weft thread can not be completely hit against the preceding weft thread as the warp threads intersect therebetween. Overall, therefore, the weft threads run obliquely to the warp threads and wrap around them. It has surprisingly been found that a particularly good combination of properties can be achieved by the use of a net-like knitted fabric. For one thing reinforced by the net-like knit metal foil, so that their robustness can be significantly improved. On the other hand, the net-like knit does not exert too much influence on the lightness of the metal foil. The resulting composite according to the invention therefore has excellent flow properties. As a result, the composite according to the invention is particularly suitable for use as a textile material for clothing, etc. Overall, a high stability and high flexibility is ensured by the individual holes of the net-like knitted fabric.

At the same time, the net-like knit has the advantage in the composite according to the invention that it can be cut without the necessity of seaming the material. This also has the advantage that any holes that occur do not cause the composite according to the invention as a whole to become unstable and fray.

The net-like knit preferably comprises a synthetic fiber. Particularly preferably, the net-like knit comprises polyester threads.

Preferably, the net-like knit comprises fibers having from 0.5 to 0.01 tex, more preferably from 0.15 to 0.02 tex and most preferably from 0.10 to 0.03 tex. Preferably, the net-like knit has a weight of 10 to 80 g / m ² , more preferably 20 to 70 g / m ² and most preferably from 30 to 50 g / m ² .

Preferably, the net-like knit is a tulle fabric. In particular, it has been found that tulle gives the composite of the invention the special combination of properties mentioned above. It is preferred that the tulle has a number of holes of 13 to 70 holes per square inch, more preferably from 20 to 60 holes per square inch, most preferably from 30 to 55 holes per square inch. The number of holes is, as known in the art, used for the classification of tulle materials. The number of holes in the vertical and diagonal row of a square inch is counted, with the corner hole counting twice.

Preferably, the tulle has no apparatus. This is in particular to improve the flowability of the resulting composite. The composite of the invention may comprise a nonwoven fabric. Non-woven fabrics are known to the person skilled in the art. These are textile fabrics made of fibers of limited size Length, filaments or cut yarns which are joined together to form a nonwoven fabric and bonded together. In one embodiment, the fibers, filaments or yarn of the nonwoven fabric are uncrossed or entangled. According to an alternative embodiment, the fibers, filaments or yarn of the nonwoven fabric may be crossed. The nonwoven fabrics according to the present disclosure have a comparatively small thickness compared to their length and width.

In a preferred embodiment, the nonwoven fabric has a heat-activatable adhesive layer on one of its surfaces. Such nonwovens are known to the person skilled in the art under the terms ironing fleece, fleece-lined or ironing insert. Such nonwovens allow the nonwoven fabric to be bonded to a metal foil by simple ironing.

The composite according to the invention furthermore comprises at least one adhesive layer, for example between the netlike knit and a metal foil, the nonwoven fabric and a metal foil, the netlike knit fabric and the nonwoven fabric or two metal foils. The adhesive layer may be any substance that has the ability to firmly bond the net-like knit to the metal foil, with very little impact on the flowability of the resulting composite. The adhesive layer preferably comprises a room temperature curing adhesive. Such adhesives are known to the person skilled in the art. This may in particular be a reactive adhesive or a solvent-based adhesive.

Preferably, the adhesive layer comprises a styrene-butadiene copolymer. In particular, it has been found that an adhesive based on a styrene-butadiene copolymer is particularly suitable for providing a strong and robust bond between the net-like knit fabric and the metal foil, while at the same time scarcely adversely affecting the textile properties of the resulting composite. In particular, the resulting composite has good flowability. Also, such an adhesive provides sufficient bonding so that the resulting composite is washable and also ironable. This adhesive is preferably a solvent-based adhesive in which the solvent vaporizes at room temperature to form the adhesive layer. This has the particular advantage that the production of the composite material according to the invention is very simple and inexpensive. The composite according to the invention preferably further comprises at least one application. Under an application is preferably understood an element which fulfilled decorative purposes. This at least one application is preferably selected from the group consisting of a rhinestone, a feather, a pearl and an additional textile material. In this case, the additional textile material is preferably selected from felt, fur, leather and tulle. In particular, by using at least one rhinestone as an application, the ability of the composite according to the invention can be further increased. Thus, the aesthetic appearance of the composite material according to the invention is increased.

In an alternative and / or additional embodiment, the composite comprises a layer of particles, preferably in an adhesive layer which is arranged between a metal foil and a textile fabric (reticulated knit fabric or nonwoven fabric). The particles may be selected from the group comprising beads, stones, platelets, spheres, grains or mixtures thereof. The particles of the layer of particles may be substantially the same size and / or shape, or may be a mixture of particles of different shape and / or size. The particles are not directly visible as such in the composite, but are covered by at least one layer of a metal foil. The particles are preferably arranged between a first metal foil and a second metal foil or the flexible textile fabric. As a result, the particles lead to a structuring of at least one surface of the composite. With this configuration, the aesthetic appearance of the composite can be increased.

use

In a further aspect of the present invention, the composite of the invention is used to make garments, appliqués, accessories, bags, jewelry, wall and / or ceiling coverings, home accessories, upholstery, rugs or art objects. In this case, the composite according to the invention can be used in all embodiments and embodiments. The art objects are preferably sculptures or decorative canvas. In addition, the composite according to the invention can be used for the production of furniture, in particular of seating furniture such as armchairs, chairs, sofas, screens and the like. In addition, for example, vehicles, especially cars, and houses on their inside and / or outside, including the floor, as well as household items such as dishes or vases can be provided with the composite material according to the invention. In further embodiments, the composite according to the invention is used for the production of posters, advertising (such as billboards) or exterior decorations.

Preferably, the composite according to the invention is used for the production of garments, accessories and jewelry. The accessories are preferably hair clips, hair ties, hair bands, belt buckles or shoe applications. The jewelry is preferably chains, bracelets, pendants for necklaces or bracelets, rings, earrings or tiaras. The garments are preferably dresses such as evening dresses, bridal gowns, cocktail dresses, T-shirts, pants, coats, pullovers, skirts, jackets, bags; Handbags, belts, veils, hats, underwear, swimwear, shoes. The composite according to the invention is particularly preferably used as an application on garments, in particular those mentioned above. Garments, in particular those mentioned above, made of a denim and / or leather are particularly preferred. In particular, it has been shown that the composite according to the invention can be applied particularly well to these substances. In this case, the combination of the denim and / or leather with the composite material according to the invention a particularly beautiful aesthetic effect can be achieved.

The use of the composite of the present invention to make garments, particularly bridal gowns, makes it possible to provide garments with particular new aesthetic effects. Thus, the garment not only - at least in some areas - have a metallic appearance corresponding to the metal foil of the composite. The use of the composite of the present invention allows modeling of the fabric / garment because it substantially retains its shape due to its strength and yet is wearable. This can be used, for example, to make clothes or skirts that are more than 3 meters wide, more than 5 meters wide, and even with widths that go significantly beyond, possibly even without the need for a hoop skirt. The use of the composite according to the invention thus makes it possible to manufacture skirts whose width goes far beyond the skirt widths of about 1.5 meters achievable with conventional fabrics.

In particular embodiments, the composite of the invention may be used to make dresses or skirts having a variable width. This means that the width and / or shape of the dress or skirt can be changed individually, without any seams requirement. The width and / or shape of the dress or skirt can even be changed while the garment is being worn.

The use of the composite according to the invention makes it possible to provide the garment with applications that would hang down when attached to a conventional fabric due to its shape and / or weight. In contrast, when attached to the composite of the present invention, they may substantially retain their location / position when properly secured. In some applications, it may be advantageous to use a per se stronger net-like knit to increase the dimensional stability of the composite. As a result, designs of three-dimensional objects can be made. In particular, the use of elevations and depressions can be used by this dimensional stability for decorative purposes.
