Description

[0001] The invention relates to a technical woven fabric, in particular for technical applications such as automotive applications.

[0002] It is a known and common practice in the art to provide electrical, hydraulic, or fluid-carrying lines in motor vehicles with a protective sheath. This sheathing protects the lines from damage.

[0003] For example, publication EP 2 152 946 B1 shows a textile hose that serves as a protective sheath and can be shrunk after being pulled onto a cable by applying heat.

[0004] In the production of the hose shown there, two weft threads are inserted into each shed formed by the weaving process, one being a multifilament weft thread and the other a monofilament weft thread. The multifilament weft thread embeds the monofilament weft thread, which forms the impact protection or mechanical protection.

[0005] The object of the invention is to create a fabric that is improved compared to the prior art. At the very least, the object of the invention is to create an alternative.

[0006] This problem(s) is solved by a technical woven fabric according to claim 1. Preferred embodiments are the subject of the dependent claims.

[0007] The technical textile woven fabric according to the invention has in particular the following characteristics: a multitude of warp threads running lengthwise in the fabric and a multitude of weft threads running crosswise in the fabric, wherein The woven fabric is available through the following weaving process: Arranging the warp threads; and Repeated formation of sheds and insertion, into at least certain of the sheds, of at least two weft threads, wherein one of the weft threads is a multifilament weft thread and another of the weft threads is a monofilament or multi-component weft thread; wherein the other of the weft threads has a cross-sectional shape in which a concave recess is formed.

[0008] The technical fabric according to the invention is preferably intended for technical applications, such as automotive applications.

[0009] The technical fabric is, for example, a large-area wide fabric that is suitable for protecting the outer wall of an electrical energy storage system.

[0010] Alternatively, the technical fabric can be a tape that can be used, for example, to encase electrical or hydraulic / fluid-carrying lines of an automobile by placing the tape on the line and rolling it up.

[0011] Preferably, the technical fabric can be woven in such a way that it forms a tube. For example, the tube is obtained in the weaving process by weaving two layers of fabric joined together at the sides.

[0012] The concave recess leads in particular to a more compact embedding of the monofilament or multi-component weft thread in the multifilament weft thread.

[0013] Insofar as the woven fabric is finished, the concave recess also forms an area in which a finishing agent can collect well.

[0014] The multifilament weft thread preferably contains between 30 and 60 filaments.

[0015] The warp threads can be multifilament. Preferably, some of the warp threads can be monofilament. Regardless of whether they are multifilament or monofilament, the warp threads can be made of PET, polyester, or polyamide. These materials include, for example, recycled materials.

[0016] Preferably, the monofilament warp threads can also have the concave recess.

[0017] The warp threads are, for example, threads with 500 dtex to 4000 dtex, especially 1250 dtex to 1350 dtex.

[0018] The other of the at least two weft threads can also have springy properties due to the concave recess, which leads to increased impact resistance of the technical fabric.

[0019] Preferably, up to four weft threads can be inserted, preferably, for example, two of the multifilament weft thread and two of the monofilament weft thread.

[0020] Preferably, the technical textile woven fabric according to the invention is designed in such a way that the concave recess is formed by having a C-shaped, U-shaped, Z-shaped, X-shaped or star-shaped cross-sectional form.

[0021] The aforementioned cross-sectional shapes lead in particular to good embedding of the monofilament or multi-component weft thread into the multifilament weft thread; in particular because the limbs of the cross-sectional shapes of the monofilament or multi-component weft thread can penetrate well between the filaments of the multifilament weft thread and good mutual adhesion of both weft threads occurs.

[0022] In the weaving process, the monofilament or multi-component weft thread is compacted or densely embedded in the multifilament weft thread by the reeding process.

[0023] In addition, these cross-sectional shapes in particular exhibit a spring effect due to the shape of the corresponding legs, thus improving the impact strength / resistance of the technical woven textile fabric.

[0024] Preferably, the technical textile woven fabric according to the invention is designed, wherein the two weft threads are inserted into the respective shed by one or more weft insertion needles, and a working edge is formed with the weft threads on one side facing away from the respective weft insertion needle, so that Each of the weft threads forms a double weft.

[0025] The fabric according to the invention is preferably produced on a needle-loom weaving machine.

[0026] The needle-loom weaving machine includes at least one weft insertion needle. If only a single weft insertion needle is provided, it holds the at least two weft threads by, for example, guiding both weft threads together through one eye of the weft insertion needle or through individual eyelets of the weft insertion needle.

[0027] The needle-band loom can alternatively include several weft insertion needles, each of which places / inserts / inserts a loop of the corresponding weft thread into the shed formed during the weaving process.

[0028] From the foregoing explanations, the two weft threads in the fabric according to the invention are preferably, due to technological reasons, double wefts, i.e., there are four threads in the respective shed, wherein one of the weft threads passes twice through the respective shed and the other of the weft threads also passes twice. If the number of weft threads is increased to four, eight threads consequently pass through the shed.

[0029] On the side opposite the respective weft insertion needle is a tongue needle that interacts with the thread loop to create a stitch forming the edge (working edge). An edge facing the weft insertion needle is preferably formed by the shed change and is therefore a selvedge, with the weft threads encircling the selvedge through the repeated formation of the sheds.

[0030] The multiple weft insertion needles can be arranged on the same side of the warp threads or the formed sheds. The tongue needle can interact with both thread loops, or a separate tongue needle can be provided for each weft insertion needle.

[0031] Alternatively, the weft insertion needles can be arranged on opposite sides of the warp threads. A corresponding needle-band loom can also be called an X-needle loom. If the weft insertion needles are arranged on opposite sides of the warp threads, there is also a tongue needle on each side, which interacts with the corresponding thread loop passed through the shed to form the stitches and create the edge (worked edge).

[0032] The woven technical fabric according to the invention can also be produced on other looms. In these cases, the two weft threads are located in the sheds such that they each form single wefts, not double wefts. If the number of weft threads is increased to the aforementioned four weft threads, there are therefore four single wefts in each shed.

[0033] Preferably, the technical textile woven fabric according to the invention is designed in such a way that the other of the weft threads exhibits a shrinkage behavior when exposed to temperature, such that the fabric can conform to an object.

[0034] One of the weft threads, the multifilament weft thread, preferentially exhibits an identical or slightly lower shrinkage behavior compared to the other weft thread when exposed to temperature.

[0035] The warp threads of the woven fabric preferably show no or only slight shrinkage when exposed to temperature.

[0036] As an alternative to the shrinkage behavior of the other weft thread, this one can be made of an elastic material, such as a thermoplastic elastomer (TPE).

[0037] Preferably, the technical textile woven fabric according to the invention is designed in such a way that the other of the weft threads exhibits the shrinkage behavior at a temperature of less than or equal to 180°C, preferably less than or equal to 150°C.

[0038] The woven fabric according to the invention is therefore very suitable for applications in which the fabric covers or encases a temperature-sensitive object.

[0039] Preferably, the technical textile woven fabric according to the invention is designed in which one material of the other of the weft threads is PVDF, polyolefin or FEP.

[0040] PVDF: Polyvinylidene fluoride. The shrinkage ratio of PVDF is preferably 2:1.

[0041] Polyolefin: The corresponding shrinkage ratio is preferably 2:1, 3:1, or 4:1.

[0042] FEP: Fluoroethylene propylene. The shrinkage ratio is preferably 1.6:1.

[0043] These materials exhibit good shrinkage behavior, particularly at the aforementioned temperature of less than or equal to 180°C, preferably less than or equal to 150°C, so that the covering or wrapping of the object can take place in an adequate time by applying the fabric and subsequently subjecting it to heat.

[0044] The other weft thread, the monofilament or multi-component weft thread, is preferably treated thermally and / or mechanically during its manufacture, in particular the corresponding extrusion, so that it exhibits the required shrinkage behavior in the specified temperature range.

[0045] An alternative material for the other weft thread could be, for example, a silane, which exhibits shrinkage behavior, for example, through network formation in the aforementioned temperature ranges.

[0046] Preferably, the technical textile woven fabric according to the invention is designed in such a way that the other of the weft threads is the multi-component weft thread which, when exposed to temperature X = 10% to 50%, in particular from 20% to 40%, exhibits melting behavior and shrinkage behavior for the remainder 100%-X.

[0047] The melting behavior causes parts of the multi-component weft thread to melt when exposed to temperature, particularly at the aforementioned temperature of less than or equal to 180°C, preferably less than or equal to 150°C, and to bond with the filaments of the multifilament weft thread through subsequent solidification.

[0048] The aforementioned percentage rates have shown a good balance between strength and connection of the weft threads.

[0049] Preferably, the technical textile woven fabric according to the invention is designed in such a way that the other weft thread has a diameter of less than 0.27 mm, preferably less than 0.25 mm. A diameter of 0.22 mm is particularly preferred. This allows for significant weight and cost savings.

[0050] Preferably, the technical textile woven fabric according to the invention is designed in such a way that the weaving process by which the fabric is obtained further comprises, after the insertion of the weft threads:

[0051] Finishing the interwoven warp and weft threads (weave) by applying a liquid finishing agent and letting it dry; wherein The equipment includes a component A and a film former B.

[0052] Component A preferably includes: - Latex, especially synthetic latex - Nitrile (rubber) - Polyurethane (PU) - silicone, - TPU (Thermoplastic Urethanes) and / or - TPE (Thermoplastic Elastomers).

[0053] The film former B preferably includes: - Acrylate copolymers, such as poly(butyl acrylate) (PBA) and poly(ethyl acrylate) (PEA) - Polyurethanes (PU dispersions) - Styrene-butadiene copolymers (SBR, SB latex) - Polyvinyl acetate (PVAc) & polyvinyl alcohol, or - Silicone emulsions (polysiloxanes).

[0054] The two preceding lists of component A and film former B are to be understood as meaning that each component A can be combined with each film former.

[0055] A combination of component A, latex or nitrile (rubber), with film former B, acrylate copolymers, is particularly preferred.

[0056] In addition to component A and the film former, the equipment may contain, for example, 50% water by volume.

[0057] The technical textile woven fabric according to the invention particularly preferably forms a hose which is intended to be pulled onto an object, such as a cable of an automobile. The cable can, for example, be a fluid-carrying or electrical cable.

[0058] The hose is preferably formed by bonding from two layers of the technical textile woven fabric, wherein the two layers are joined together at their respective edges.

[0059] The tube is preferably produced on the aforementioned needle-loom weaving machine, so that the connection of the layers mentioned at the edges is formed by the selvedge (weft insertion side), where the weft threads are circumferential, or the warp edge.

[0060] The finishing of the interwoven warp and weft threads (binding) is preferably carried out by passing the binding of the interwoven warp and weft threads through a bath with the finishing agent, then squeezing and drying.

[0061] The squeezing process takes place, for example, under a pressure of 1 bar.

[0062] The finishing of the fabric preferably leads to a weight increase of 10% to 20% in the final dry state.

[0063] A preferred embodiment of the technical textile woven fabric according to the invention is explained below with reference to the accompanying figures. Fig. Figure 1 shows a positive binding cartridge of the fabric of the preferred embodiment, wherein the binding cartridge corresponds to a layer of a textile tube and a top view of an outer surface of the tube; and Fig. 2A and Fig. 2B serves to explain the structure of at least two weft threads, whereby Fig. Figure 2A shows a cross-section of a multifilament weft thread and various alternatives for a monofilament or multi-component weft thread and Fig. 2B shows a cross-sectional view of a web pocket.

[0064] The technical textile woven fabric according to the invention (hereinafter simply referred to as technical fabric or fabric) according to a preferred embodiment of the invention comprises a plurality of warp threads running in the longitudinal direction of the fabric and a plurality of weft threads running in the transverse direction of the fabric.

[0065] The technical fabric is particularly obtainable through a weaving process characterized by the arrangement of the warp threads, repeated formation of sheds and insertion of the weft threads.

[0066] A characteristic feature of the weaving process is that at least two weft threads are inserted into at least some of the sheds, preferably into each shed, wherein one of the weft threads is a multifilament weft thread and another of the weft threads is a monofilament or multi-component weft thread. Preferably, up to four weft threads can be inserted; for example, two monofilament weft threads and two multifilament weft threads.

[0067] The technical fabric according to the invention is used for technical applications, in particular for the protection of an object or element of a motor vehicle, such as an electrical energy storage device, or electrical or fluid-carrying lines of the motor vehicle.

[0068] The preferred structure and thermal properties of the weft threads will be discussed in more detail below. (Binding of the technical fabric)

[0069] Fig. Figure 1 shows a positive binding cartridge 10 of the technical fabric according to the preferred embodiment.

[0070] The technical fabric according to the invention is particularly preferably a woven tape that extends in a longitudinal direction and is produced, for example, on a needle-loom weaving machine.

[0071] The technical fabric is particularly preferred as a textile tube, which can be obtained by creating two overlapping strips or layers joined at the edges.

[0072] The binding cartridge according to Fig. Figure 1 shows, as an example, four warp threads 1k to 4k running lengthwise in the technical fabric. The warp threads shown, 1k to 4k, form a warp repeat that – as indicated by the dots – runs to the right.

[0073] The reed insertion is preferably designed such that the four warp threads 1k to 4k pass through a reed gap. Each of the four warp threads is also preferably assigned a shaft. The distribution of the warp threads can also be varied depending on the width of the woven technical fabric. For example, 8, 10, 12, ..., warp threads can pass through each reed gap.

[0074] Overall, the technical fabric 10 actually contains a large number of warp threads 1k to 4k or a large number of the warp repeat shown.

[0075] Insofar as the technical fabric is designed as a tape or tube, the number of warp threads is of such a magnitude that the width of the tape or tube is between 15mm and 200mm, in particular between 50mm and 60mm.

[0076] The warp threads are, for example, multifilament warp threads or monofilament warp threads, with, for example, 500 dtex to 4000 dtex, especially with 1250 dtex to 1350 dtex.

[0077] The binding cartridge according to Fig. Figure 1 further shows a total of eight lines, 1s to 8s, each corresponding to weft threads running in the transverse direction.

[0078] Each line corresponds to a respective web pocket formed in the weaving process, into which the respective shot is taken.

[0079] As already explained, two weft threads are preferably inserted into each shed formed in the weaving process. These are, firstly, the multifilament weft thread and, secondly, the monofilament or multi-component weft thread.

[0080] For the sake of simplicity, it is assumed below that the at least two weft threads are inserted into each shed. The invention is not limited to this; it is possible that the at least two weft threads are inserted into only some of the sheds, and that only one of the weft threads, preferably the multifilament weft thread, is inserted into the remaining sheds.

[0081] Under the assumption made, this corresponds to Fig. 1 each of the rows 1s to 8s each the at least two weft threads that run in the transverse direction of the technical fabric in the obtained weave.

[0082] Lines 1s to 4s correspond to a shot report, which restarts in line 5s. Therefore, it is understandable and obvious that lines 1s and 5s are identical.

[0083] Each box of the binding cartridge corresponds to a binding point where the warp thread of the column crosses with the at least two weft threads of the respective row.

[0084] If a box is filled, the warp thread runs above the corresponding weft threads; if it is empty, the warp thread runs below the corresponding weft threads.

[0085] Technical fabric can be produced with any type of loom, but especially with needle-punched looms.

[0086] The weaving process by which the technical fabric is obtained is particularly preferred if it is carried out using a needle-guided weaving machine which includes at least one, preferably two, weft insertion needles SEN1 and SEN2.

[0087] If only a single weft insertion needle SEN1 is provided, it holds both (or all) weft threads by guiding the weft threads through one or more eyelets formed in the weft insertion needle SEN1. This design ensures that all weft threads are inserted into each shed.

[0088] The following explanations assume that two weft insertion needles SEN1 and SEN2 are provided. The invention is not limited to this.

[0089] The shot insertion needles are in Fig. 1 shown on the left side of the binding. Each weft insertion needle SEN1, SEN2 holds a loop of one of the at least two weft threads, the corresponding weft insertion needle inserting / bringing / laying the respective loop into the respective shed in the weaving process by passing through the shed and, after the corresponding weft thread has been stitched, being withdrawn from the shed on the side facing away from the weft insertion needles SEN1, SEN2.

[0090] The meshing is done using a tongue needle and serves to form a corresponding edge on the opposite side.

[0091] The tongue needle can, for example, form the edge by i. forms a stitch from the respective weft thread introduced as a loop, ii. ties off the loop formed from the respective weft thread over an introduced catch thread that forms the stitch, iii. forms a stitch from the respective weft thread introduced as a loop and at least one introduced catch thread, or iv. forms a stitch from the respective weft thread introduced as a loop, at least one introduced catch thread and one introduced barrier thread.

[0092] Variant iv. is preferred.

[0093] The edge formed by the tongue needle is, therefore, a working edge due to the technology.

[0094] On the side facing the weft insertion needles SEN1 and SEN2, the edge is formed by the shed change. The edge facing the weft insertion needles SEN1 and SEN2 is therefore a selvedge.

[0095] Since – understandably – the weft insertion needles SEN1 and SEN2 each place a loop of the respective weft thread into the shed, each weft thread passes through the shed twice, so that in Fig. 1 each row 1s to 8s corresponds to four threads, or generally to twice the number of weft threads used.

[0096] The in Fig. The warp threads shown in columns e1 and e2 are located at the outer end of the weave and serve to form the edges; in the case of a needle-loom loom, they form a working edge. Columns e1 and e2, and the weaves of the corresponding warp threads, can be arbitrary.

[0097] As an alternative to the left-side arrangement of both weft insertion needles SEN1, SEN2, one of the weft insertion needles SEN1, SEN2 can be arranged on each side of the warp threads 1k to 4k, so that the weft threads are inserted into the corresponding shed from different sides and a working edge (by means of a corresponding tongue needle) is created on each side. (Structure and thermal properties of the weft threads)

[0098] Fig. 2A and Fig. Figure 2B serves to explain the structure of the at least two weft threads.

[0099] Fig. 2A schematically shows a sectional view (longitudinal section) of a shed formed in the weaving process according to line 4 of the binding cartridge. Fig. 1, into which at least two weft threads are inserted. The sectional view corresponds to that in Fig. 1 shown section line SL2.

[0100] It is evident that one of the weft threads 2 is the multifilament weft thread 2 and the other of the weft threads is the monofilament or multi-component weft thread 3.

[0101] The section view from Fig. 2A illustrates that each of the weft threads 2, 3 is inserted into the shed as a loop and thus passes through the shed twice.

[0102] The multifilament weft thread 2, for example, has between 30 and 60 filaments, but can also have 100 filaments or more.

[0103] The design of the monofilament weft thread 3 is in accordance with the invention and is essential.

[0104] This has a cross-sectional shape in which at least one concave recess 31 is formed. In particular, the cross-sectional shape is in Fig. 2A x-shaped, so that the cross-sectional shape has four concave sections 31.

[0105] The cross-sectional shape or the concave sections 31 result in the monofilament weft thread being well embedded in the multifilament weft thread 2.

[0106] In particular, the multifilament weft thread 2 or the corresponding filaments fit well into the concave sections 31 and / or the x-shaped legs of the cross-sectional shape penetrate well between the filaments when, in the weaving process, after the weft threads 2, 3 are inserted, a reed beat is made and the weft threads 2, 3 are tied off.

[0107] Furthermore, the convex sections form 31 areas in which a finishing agent, if provided, is applied to the resulting bond. The finishing of the bond is explained in more detail below.

[0108] Furthermore, the cross-sectional shape has mechanical properties that give the technical fabric good impact resistance.

[0109] The x-shaped legs of the cross-sectional shape exhibit a spring effect by bending when a force is applied to the technical fabric.

[0110] Fig. 2B shows, in addition to the x-shaped weft thread, 3 alternative weft threads 3a and 3b in section.

[0111] The alternative weft threads 3a and 3b have different cross-sectional shapes. Weft thread 3a has a z-shaped cross-sectional shape, and weft thread 3b has a c-shaped cross-sectional shape. A star shape (not shown) is also conceivable.

[0112] The aforementioned alternative cross-sectional shapes have similar effects to the x-shaped cross-sectional shape.

[0113] The in Fig. The maximum diameters dx, dz, dc of the weft threads 3, 3a, 3b shown in Figure 2A are d less than or equal to 0.27 mm, preferably less than or equal to 0.25 mm. Particularly preferably, the diameters are 0.22 mm. A diameter dm of the multifilament weft thread 2 is preferably slightly larger than the diameters dx, dz, dc of the weft threads 3, 3a, 3b.

[0114] The materials of the warp and weft threads can be chosen differently depending on the intended use of the fabric.

[0115] Provided that the fabric – be it as a large-area structure, band or tube – is precisely adapted to an object to be protected, the warp threads can be made of low-shrinkage materials.

[0116] However, it is preferred that the fabric exhibits shrinkage behavior when exposed to temperature.

[0117] One of the at least two weft threads, the multifilament weft thread, exhibits a strong shrinkage behavior when exposed to temperature, which is slightly less than the other of the at least two weft threads, the monofilament or multi-component weft thread 3.

[0118] In this respect, the multifilament weft thread 2 and the other of the at least two weft threads 3 are made of a highly shrinkable material that exhibits a shrinkage behavior, in particular a strong one, when exposed to temperature.

[0119] The warp threads 1k to 4k are made of low-shrinkage material that exhibits no or only minimal shrinkage when exposed to temperature changes. For example, the warp thread material is polyester, PET, or polyamide.

[0120] Overall, this design allows the fabric to be easily applied to the object to be protected, as the covering formed from the fabric is larger than the object and can be adapted to the object by applying temperature after application / covering.

[0121] If the temperature applied for the shrinking process is not critical in relation to the object being protected because the object is not temperature-sensitive, the weft thread material 3 can be, for example, HDPE or LLDPE. In this case, the temperature applied for the shrinking process is approximately 230°C.

[0122] However, the technical fabric is particularly preferably designed such that the shrinkage process takes place in a temperature range of 135°C to 185°C, especially between 140°C and 180°C. The other of the at least two weft threads, the monofilament or multi-component weft thread 3, is preferably made of PVDF, polyolefin, or FEP in this case. During its production, particularly the corresponding extrusion, the weft thread 3 is thermally and / or mechanically treated to exhibit the required shrinkage behavior within the specified temperature range. (Equipment of the binding)

[0123] Ultimately, the technical fabric according to the invention is preferably coated.

[0124] This is achieved by the fact that the weaving process, by which the fabric is obtained, continues to have the following step after the insertion of the weft threads: Finishing the interwoven warp and weft threads, i.e., the binding, by applying a liquid finishing agent and letting it dry.

[0125] For example, the binding, whether in the form of a large-area fabric, tape or tube, is passed through a bath with the finishing agent, then squeezed out and finally dried.

[0126] The equipment includes a component A and a film former B.

[0127] A combination of component A made of latex or nitrile (rubber) with film former B based on acrylate copolymers is particularly preferred.

[0128] Furthermore, the equipment or equipment fleet may contain up to 50% water by volume.

[0129] The film-forming agent B has the particular effect of preventing the film of the finishing agent formed on the bond carried from the bath from tearing off. The dried final coating of the fabric is thus closed, preventing the release of particles from the other of the at least two weft threads, the monofilament or multi-component weft thread 3.

[0130] The statements preceding the description apply equally to the embodiment and vice versa.
