Description

Textile material with electrically acted threads

The invention relates to a textile material, such as suede material, which has at least one textile base material and from this wegstehende pile threads, wherein the suede material is preferably made of a Polflächengebilde, the Polflächengebilde two spaced apart and mutually parallel base layers and has a connecting the two base layers pile structure, which is formed by pile threads, and the pile threads are formed by separating the pile threads apart. The velor material may also be made in other ways, for example of epoxy material, comprising a textile base material and pile loops extending therefrom. Further, it is possible to produce the suede material also in a process in which first the base layer is coated with adhesive and then the pile threads or pile loops are applied in an electrostatic process.

The invention further relates to a textile material having at least two textile base layers which are connected to each other via pile threads, and which is preferably designed as Polflächengebilde.

From DE 10 2006 034 719 B3 a suede material is known, the base layers each having electrically conductive threads, wherein in the base layers a number of textile threads is replaced by the electrically conductive threads.

DE 10 2007 018 684 A1 describes a suede material which has electrically conductive threads which form signal transmission conductors and / or energy transmission conductors for electrical and / or electronic components to be attached to the textile base material.

Object of the present invention is to provide a textile material that is optimally matched to the use of electrically acted threads.

According to the invention, this object is achieved with the subject matter of claim 1. This solution is a textile material which has at least one textile base layer and pile threads or pile loops protruding therefrom. It is essential that the at least one textile base layer has electrically actable threads. In this case, according to alternative a), it may be provided that the at least one textile base layer has no or fewer pile threads or pile loops in a region in which the electrically actable threads are arranged than in a region in which threads which are not or less electrically actable are arranged are. This means that the region in which the electrically actable filaments are arranged is covered less or not at all by pile threads or pile loops. Alternatively or additionally, it may be provided according to alternative b) that the at least one textile base layer in a region in which the electrically actable filaments are arranged, at or near their surface on the side from which the pile threads or pile loops are located, has an area or volume fraction of electrically actable filaments which is greater than the surface or Volume fraction of electrically actable filaments on the side facing away from the pile filaments or pile loops side of the textile base layer. This means that in this case, the electrically acted filaments can be arranged relatively closer to the surface of the textile base layer and thus act more effectively to the outside. It can be provided that the surface area or volume fraction of electrically actable filaments is greater in that a larger portion of the electrically actable filaments is arranged to rest on the surface of the textile base layer. But it can also be provided that the surface or volume fraction of electrically acted filaments on the surface of the textile base layer is lowered or increased by increasing the number of Umschiingungspunkte in this area, depending on whether between the points of contact of the electrically acted thread within the textile Base layer or resting on top of the textile base layer and depending on whether in the region of Umschiingungspunkte the electrically acted thread extends through the surface of the textile base layer or immersed in the textile base layer runs. It can be provided that in the region with a larger surface or volume fraction of electrically actable filaments, ie more Umschiingungspunkte in which the electrically actable filaments are wrapped around the transverse textile threads are arranged close to the surface. In alternative b), it is not absolutely necessary for fewer or no pile threads or pile loops to be present in the region in which the electrically actable threads are arranged are arranged.

In preferred embodiments, the textile material is suede material, preferably a suede material with at least one textile base layer, from which pile threads or pile loops protrude on one side. However, there are also provided embodiments in which the textile material is formed as Polflächengebilde, i. a material of two or more textile base layers, which are connected to each other via pile threads. It is envisaged that in these embodiments, too, pile threads or pile loops are arranged so as to stand on one side. This means that in the different embodiments of the textile materials only a textile base layer or a second or more textile base layers are provided, wherein adjacent textile base layers are each connected via pile threads.

By training with two or more textile base layers a particularly strong and / or durable textile material is obtained, which is versatile. The base layer arranged in the top of the insert can be designed so that it not only fulfills a technical function, but also has a decorative effect.

The electrically acted threads are at least partially electrically acted upon. They can consist of electrically conductive material. It can be provided that the electrically actable filaments form heating conductors. It can also be provided that the electrically acted filaments are formed as electrically actable self-luminous threads, z. B. as electroluminescent threads. Alternatively or additionally, it may be provided that the electrically actable threads Signal transmission conductor and / or energy transmission conductor for arranged on the textile base material and / or introduced into the textile base material electrical and / or electronic components. In this case, provision may be made for the first electrically actable filaments to form energy transfer leads for second filaments that can be acted upon electrically. It can be provided that the second electrically acted threads are formed as self-luminous threads.

The fact that according to alternative a) in this area in which electrically actable threads are arranged in the base layer, no or less pile threads or pile loops are arranged, there are significant functional advantages. If the electrically acted filaments are formed, for example, as electrical heating conductors, they can unfold their heating effect more or less freely, because they are not or less wrapped by textile material. If the electrically acted threads are formed as self-luminous threads, there is an increased luminous effect, since the self-luminous threads are not or less covered by pile threads or pile loops. Corresponding advantages arise when according to alternative b) it is provided that the at least one textile base layer in a region in which the electrically actable threads are arranged, at or near their surface on the side from which the pile threads or pile loops are away, has a surface or volume fraction of electrically acted threads, which is greater than the area or volume fraction of the electrically acted filaments on the side remote from the pile threads or pile loops side of the textile base layer. In these cases, it is not necessary to reduce the density of the pile threads or pile loops in the regions in which electrically actable threads are arranged. The pile threads or Pile loops can be formed over the entire surface area of the textile base layer regardless of whether in certain areas of the textile base layer electrically acted filaments are arranged to be constantly dense.

The regional absence of the pile threads or pile loops in alternative a) can be achieved in that the pile threads run in the relevant area parallel to the base fabric without or with fewer loops. Alternatively, the pile threads or pile loops may be partially removed.

It can be provided that at least one textile thread of the base layer is replaced by an electrically acted thread, ie instead of the conventional base layer, which consists exclusively of textile threads, an electrically actable thread, which is arranged the same as the herkömmiiche textile thread used , Trained as a suede material textile material according to the invention is distinguished from known solutions in which electrically actable threads are applied to tissue, characterized in that the electrical actable filaments can be incorporated into the base layer of the textile material and therefore at least additionally protected against damage. The textile material according to the invention is therefore particularly durable. Because there are no or fewer pile threads or pile loops in the areas in which electrically actable threads interact with the environment, the electrically actable threads can optimally interact with their surroundings. The textile material according to the invention may, as stated, be a suede material. The suede material can be produced from a pile fabric, the pile fabric having two spaced-apart and mutually parallel base layers having a pole structure connecting the two base layers, wherein the pile structure is formed by pile threads. By cutting the Polflächengebildes in the field of pile threads creates the velor material with protruding pile threads, which are formed when cutting the pile threads. The textile material according to the invention may also be an epoxy material which is produced from a pile fabric in which pile loops protrude from a base layer. The pile loops can be cut open in special versions during the manufacturing process or even later, for example by shearing.

The base layer provided with the adhesive is then provided, in an electrostatic field oriented at least approximately perpendicular to the base layer, with the pile threads, which are aligned at least approximately vertically by the electrostatic field to the plane of the base layer and fixed by the adhesive to the base layer. This is followed by drying of the suede material produced in this way.

The adhesive is preferably applied to the base coat, for example sprayed on. Conveniently, the velor material is sheared smooth after the drying. After this smooth shearing, at least one refining process step can be carried out. This finishing process step may, for example, be a printing of the velor material.

Material in a schematic sectional view;

Fig. 1 shows a Polflächengebilde 1, which forms a precursor for the production of textile material formed as a suede material. The Polflächengebilde 1 has two spaced-apart and mutually parallel base layers 11 and a pole structure 12, the two base layers 11 together combines. The two base layers 11 may be formed as a woven fabric, as knitted or knitted fabric. The pole structure 12 is formed by pile threads 12p.

The two base layers 11 each have, in addition to textile threads 11t, electrically actable threads 11e. For clarity, only some of the textile threads 11t are provided with reference numerals in the figures. The two base layers 11 are formed in the embodiment shown in Fig. 1 and 2 of warp 11 k and weft threads 11s. Warp threads 11k and weft threads 11s are mainly textile threads 11t. The electrically actable filaments 11e may be warp threads or weft threads. In the exemplary embodiment illustrated in FIG. 1, electrically loadable threads 11e extend essentially parallel to the weft threads 11s, wherein in the case shown, they each loop around consecutive warp threads 11k alternately from above or from below. As can be seen in FIG. 1, the pile threads 12p may be formed in sections as weft threads and run in this section in the base layer 11, in the illustrated case in the section of the base layer alternatingly looping successive warp threads from above or below. In other areas of the base layer, the pile threads each successively loop around a warp thread 11 k of a base layer 11 and then a warp thread 11 k of the other base layer 11.

FIG. 2 shows a textile material 2 designed as a suede material, which is formed by cutting the pile threads 12p in FIG. 1 in a parallel center plane running between the two base layers 11. As can be seen in FIG. 2, the pile threads 13 formed from the cut pile threads have different colors, which are represented by different hatchings, and thus form colored patterns in the textile material 2. It may also be monochromatic or piece-dyed materials. It can be provided that the two textile materials 2 formed by cutting open the pile surface structure 1 are designed differently, preferably with different patterns. Preferably, however, it can be provided that the two textile materials 2 formed by cutting open the pile sheet 1 are of the same design, preferably of the same design. The end sections of the pile threads 13 projecting perpendicularly to the base layer 11 are fanned out and thus produce a velvet-like appearance of the textile material. As can be seen in Fig. 2, the cut pile threads form loops around the warp threads 11 k of the base layer 11, which adhere to the warp threads 11 k substantially by frictional engagement. However, it can also be provided to fix the pile threads 13 by additional means, for example by an adhesive layer arranged on the back side of the base layer. As an alternative to the exemplary embodiment illustrated in FIG. 2, which is suede material, the textile material may be formed as an epingulum material that differs from the suede material in that only one base layer is provided in the production process and that instead of the pile yarns, pile loops are provided are. In preferred embodiments, it is provided that the pile loops are cut open by shearing. Thus, a suede material can be produced, which is similar or identical to the structure of the suede material produced from the Polflächengebilde.

In the case of the velor material shown in FIG. 2, the distribution of the pile threads 13 is different in different areas. In two areas in which electrically actable conductors 11e are arranged, fewer pile threads 13 are arranged. In the case of the suede material in FIG. 2 it can be provided that the electrically actable threads 11e are designed as heating filaments. In other, also very advantageous embodiments, the electrically acted threads can also be designed as electrically self-illuminating threads. The luminous effect of the self-luminous filaments is preferably based on electroluminescence. The self-luminous thread has an electroluminescent dye, which is excited by an electric field to shine. The self-luminous thread therefore has two electrically conductive layers, which are connectable to an electrical voltage source and between which the electric field is formed. The electrical voltage source preferably provides an alternating voltage in the low-frequency and / or audible frequency range (20 kHz). A typical self-luminous thread may have a rotationally symmetrical structure with an electrically conductive central inner conductor and a cylindrical transparent outer conductor, between which electroluminescent material is arranged, which may be surrounded by an outer protective layer. The outer conductor can be enveloped by a transparent colored protective layer. It is also possible to dispense with the central inner conductor and to provide two outer conductors electrically insulated from each other. For contacting the self-luminous thread 11e, the two electrically conductive layers of the thread can be exposed at the contact point and be connected for example by a clamp connector with electrically isolated from each other insulated jaws electrical connection contacts with electrical leads that produce an electrical connection to the electrical voltage source. For stationary applications, the electrical power source can be considered a to the public grid connectable power supply can be formed. In preferred embodiments, the contacting of the self-luminous threads may be provided by a cutting connector, which cuts through the insulation in one operation and contacts the electrically conductive layers of the self-luminous thread. A particularly simple contacting is possible if contacting areas are provided in the textile material in which the self-illuminating threads introduced in the textile material are arranged close to each other in the manner of a ribbon cable so that a correspondingly dimensioned cutting connector, for example an 80-pole cutting connector, can be used is.

FIGS. 3 to 5 now show application examples for the textile material according to the invention, in which the electrically actable filaments are designed as self-illuminating filaments that can be acted upon electrically.

Fig. 3 shows a trained as a band-shaped velor material textile material 3, which is intended as an escape route marking in the bottom area of vehicles for passenger transport, for example, for use in buses, trains, aircraft and ships. The textile material 3 has in the case shown alphanumeric characters 31 and a pictogram 32, which mark an escape route. The characters 31 and the icon 32 are formed of self-luminous threads. The self-luminous threads occur in the area of the characters 31 and the pictogram 32 on the surface of the base layer of the textile material 3 and are covered in the other areas in the base layer of the textile material of textile threads and / or pile threads and therefore not visible. In the embodiment illustrated in FIG. 3, the alphanumeric characters 31 formed from the self-luminous threads form the word "EXIT" and the icon 32. The icon 32 is a directional arrow indicating the way to the exit or emergency exit.

These electrical components can be external assemblies that are attached to the band-shaped textile material 4 and / or on a base on which the textile material 4 is applied. It may be, for example, a reading light 41, a fan 42 and switch 43, but also to speakers and microphones. The reading light 41 and the fan 42 are switched on and off by the switch 43. From the self-luminous threads, a pictogram 44, which is designed as a stylized fan, and star-shaped decorative elements 45 are formed in the manner described in Fig. 3 above.

The textile material 5 may for example form an ornamental border of a textile for the interior of rooms or be provided as a decorative element for wall and / or ceiling panels or as a decorative element for furniture. It can also be provided to form the decorative element 51 exclusively of self-luminous threads, preferably in several colors, or to form the decorative element 51 from textile pile threads and, moreover, from self-illuminating threads.

FIGS. 6a to 6f show the production and use of a textile material equipped with an electrical functional element using electrically actable filaments which are designed as electrical conductors for supplying electrical functional elements or as heating conductors.

FIG. 6a shows a schematic representation of a textile base layer 11 provided as the starting material of the textile material, which has, in addition to textile threads 11t, electrically loadable threads 11e. The electrically acted threads 11e are arranged in the textile base layer 11 instead of textile threads. The electrically acted filaments 11e may be formed differently depending on the purpose, for example, be formed of different materials or have a different structure. The electrical acted upon filaments may for example be formed as a strand to form a comparable flexibility of the textile filaments and / or having an electrically insulating coating. The electrically acted filaments may further have different electrical properties, for example, have different electrical conductivity, whereby they are specially formable as electrical conductors or as heating conductors. FIG. 6b shows the textile base layer 11 in a second production step. The textile base layer 11 is partially coated with an adhesive layer, 11 kl, wherein the sections in which the electrically acted filaments 11 e are in operative connection with the environment or in which components are arranged after completion of the textile material, no adhesive layer 11 kl have.

6c shows the electrostatic coating of the textile base layer 11 with pile threads 13. The pile threads 13 align in an electrostatic field 14 and are fixed on the textile base layer 11 by the adhesive layer 11kl. The textile base layer 11 is moved through the electrostatic field 14, so that the entire textile base layer 11 is coated with pile threads 13. However, the pile threads 13 adhere only in the sections of the textile base layer 11 provided with the adhesive layer 11.

FIG. 6 d shows a textile material 6 which is formed by the above-described coating of the textile base layer 11 with pile threads 13. In the areas in which the electrically acted filaments 11 e are in operative connection with the environment or which are provided for receiving electrical components, contact elements or the like, no pile filaments 13 are arranged.

6e and 6f show the textile material 6 equipped with a light-emitting diode 61, which further has a heating surface 62, in which electrically actable filaments 11e designed as heating conductors are arranged. In the exemplary embodiment illustrated in FIGS. 6e and 6f, no pile threads 13 are arranged on the heating surface 62. However, it can also be provided that fewer pile threads 13 per unit area are arranged on the heating surface 62 than in the others Florfäden coated areas, on the one hand to unify the visual impression of the textile material 6 and on the other hand to allow improved heat dissipation.

No pile threads 13 are arranged in the region of the light-emitting diode 61, so that the light emission of the light-emitting diode 61 is not hindered. As can be seen in FIG. 6 e, the height of the light-emitting diode is smaller than the length of the pile threads 13, so that the light-emitting diode 61 does not protrude beyond the surface of the textile material 6 and is therefore largely protected against mechanical damage. The light-emitting diode 61 may be, for example, a so-called SMD component. Surface-mounted device (SMD) devices are surface mount devices that have no wire connections and that are soldered directly to a circuit board or the like by solderable pads.

Fig. 8 shows a textile material 7, which is formed as a suede material. It consists of a textile base layer 11, projecting from the pile threads 13. In the textile base layer 11 electrically acted bare threads 11 e are incorporated. The electrically actable threads 11e may be provided as additional threads in the textile base layer 11 formed as a fabric. The electrically acted threads are arranged in certain sections of the textile material. In other areas, no electrically actable filaments 11e are arranged. Some of the electrically acted filaments emerge in sections from the base layer, by being arranged partially resting on the surface of the textile base layer 11. In FIG. 7 four different regions a, b, c and d are present in which electrically actable filaments 11e are arranged in the base layer 11. In areas b and d are the electric can be acted upon threads running only within the base layer 11. In the areas a and c are also on the top extending electrically acted filaments 1 1e present.

In the embodiment in Fig. 7 projecting pile threads 13 are provided. Their arrangement is different density in different areas. There are no pile threads in areas a and b. In area d, the pile threads are arranged at a lower density. The regions a, b and d each contain electrically actable threads in the base layer 11. The differently dense or missing arrangement of the pile threads 13 thus corresponds to the previously discussed alternative a) of claim 1, as described in the exemplary embodiments in the preceding FIGS. 6a to 6f is realized. In contrast, in the region c, in which also electrically actable threads are provided in the base layer, the arrangement of the upstanding pile threads 13 are performed in the same density as in areas in which no electrically acted filaments are arranged in the base layer. This range corresponds to alternative b) of claim 1, which provides that electrically actable filaments are arranged with a larger area or volume range at or near the surface of the textile base layer. In such embodiments, it is possible to make the density of the arrangement of wegstehende pile threads or pile loops constant as in areas of the textile base layer without electrically acted threads.

In the exemplary embodiment in FIG. 8, corresponding regions a, b, c and d are present in which electrically actable filaments 11e are provided with greater density than in regions lying between them. In the areas a, b, c, d extend electrically acted filaments 11e each in this section on the upper side of the textile base layer 11 resting, so that in these areas a larger area or volume fraction of electrically acted filaments is provided, as in other areas in which the electrically acted filaments 11e in the fabric transverse weft threads 11s arranged alternately wraps are. The areas a, b and d represent embodiments of the alternative a) of claim 1, since they represent areas in which electrically actable threads are present and less or no protruding pile threads or pile loops are provided in these areas. The area c represents an embodiment of the alternative b) of claim 1. In this area, the surface or volume fraction of electrically actable filaments is particularly large due to the guided on the surface of the textile base layer 11 electrically acted filaments 11 e. The density of the protruding pile threads 13 or pile loops can therefore be of the same size in this area as in adjacent areas in which there are no or less electrically actable threads in the textile base layer 11.

In Fig. 9, a textile material 8 is shown, which consists of two textile base layers 11, 11 ', which are connected to each other via pile threads 12p. In the upper textile base layer 11 electrically acted filaments 1 1e are arranged. In the lower textile base layer 11 ', no electrically actable filaments 11e are provided.

At the outwardly facing upper side of the textile base layer 11, which is thus facing away from the second textile base layer 11 'and the pile threads 12p, wegstehende pile threads 13 are arranged. The pile threads 13 are arranged in different densities. In areas in which electrically actable filaments 11e are arranged in the textile base layer 11, At the top no pile threads 13 are arranged. The pile threads 13 are arranged exclusively in the regions in which no electrically actable threads 11e run in the base layer 11. In that regard, it is a realization of the alternative a) of claim 1. In addition, in Fig. 9 in a section on the left side, in which electrically actable filaments 11e are arranged in the upper base layer 11, nor provided that in this area no pile threads 12p are present, which connect the textile base layers 11, 11 'in this area. In addition, alternative embodiment b) of claim 1 may also be implemented in a variant with respect to FIG. 9 having two base layers 11 and 11 ', for example in a design of the base layer 11 as shown in FIGS. 7 and / or 8. Further, with respect to Fig. 9 modified embodiments are conceivable in which more than two textile base layers are present, which are connected via pile threads. Furthermore, modified versions with one or more textile base layers are possible in which not only on an upper side pile threads 13 or pile loops are arranged projecting, that is, embodiments are possible in which pile threads 13 or pile loops are arranged wegstehend also on the underside of the textile material.
