Description

Film for textile structures
Technical Field
The invention relates to a film for textile structures, comprising a fabric layer having warp threads and weft threads, each having a thread fineness of at least 550dtex, and at least one coating layer applied to the fabric layer.
Background
For example, the use of relatively strong fabrics as materials for building envelopes has been established architecturally. In technical terms, the corresponding fabric is also referred to as "film" or "woven film". In addition to strength, certain elongation properties and other material properties, such films should have, in particular, high weathering resistance.
Textile films are often coated with a polymer, typically polyvinyl chloride (PVC), to improve weatherability. The coating is applied on both sides. Subsequently, a paint layer is applied over the polymer coating to achieve even greater weatherability.
Textile membranes have so far been based on fabrics woven from suitably strong threads or yarns in plain weave or Panama weave (Panama weave), such as 2/2 Panama weave. The use of these types of knitting in textile membranes has the following advantages: a low set (linear density) of coating can achieve sufficient surface coverage and strength. Its advantages are no need of special loom, and simple and quick production (in terms of braiding time). The disadvantage to be mentioned is the limited feasibility, which depends on the linear density and thus limits the strength.
Despite the inherently superior properties of the known textile films, there is clearly a need to further improve the durability of such products. Furthermore, it has also proved to be disadvantageous in terms of mechanical properties for certain applications: the elongation in the warp direction on the one hand and in the weft direction on the other hand show a large difference, which also makes it necessary to position the textile film accordingly depending on the load in the installed state or to take into account direction-dependent inhomogeneities in the material properties in the planning stage.
Disclosure of Invention
The object of the invention is to provide a textile film of the above-mentioned type which has approximately the same elongation properties in the yarn and in the weft and which has a high resistance to weathering.
This object is achieved by a membrane of the aforementioned type if the fabric layer is formed by a float of weft threads on at least 4 warp threads. In this case, the weft threads pass over at least 4 warp threads on the upper side of the membrane. Similarly, the warp may preferably float over at least 4 wefts. Preferably, a satin weave is used for this purpose.
Within the scope of the present invention, it has been recognized that several improvements can be achieved by the formation of a general textile film of satin weave or variants thereof, or, in general, by floats according to the definition of weft yarns over at least 3 warp yarns. First, the warp and weft show considerably fewer crossing points or longer floats than a plain weave or a panama weave, which is why a higher linear density can be selected without any problems. By satin weaving or with appropriate float substitution, the fabric structure is optimized so that the thickness of at least one coating layer is also positively influenced and, above all, the occurrence of thin spots in the coating layer is avoided for high-structure fabrics. Secondly, the formation of a fabric layer, particularly with a satin weave, also leads to the fact that the difference in elongation in the warp or weft direction is significantly less than with a plain or panama weave. This is again due to the fact that: the warp and weft have significantly less interweaving, and thus the elongation properties in the warp and weft directions are also reduced accordingly. Furthermore, the satin weave brings additional advantages: since the multiple warps of the warp can increase the linear density in the warp direction and the weft direction as compared with both plain weave and panama weave, improvement in mechanical properties at the same thickness can be achieved. Finally, there is also an advantage in terms of hand since the surface (effect of warp on the right side of the fabric, effect of weft on the left side of the fabric) is significantly smoother than in the case of the previous plain or panama woven textile films.
For woven films, the thread titer may be at least 1000dtex, preferably 1100dtex or higher.
For the reasons mentioned above, it is preferred that the weft threads cross over at least 4 warp threads, in particular 5 to 7. In particular, to achieve the desired performance discussed in the preceding paragraph, a five and eight harness satin weave may be used, whereby the weft yarns may pass over 4 or 7 warp yarns before being recombined. In general, the floats of warp and weft threads may cross, e.g. at least 4, e.g. up to 7-9 (warp) threads, depending on the choice of weaving cycle and number of successive, e.g. in a classical satin weave, the threads may float in at least 4 (five bundles) or up to 7 (eight bundles) or more warp and weft threads, depending on the chosen number of weaving cycles and pitches. Derivatives of satin weaves (e.g., reinforced satin weaves) may achieve similar effects.
Typically, the warp and/or weft yarns are each formed from multifilament yarns. In particular, both the warp and the weft are formed from multifilament yarns. The multifilament yarn has the required strength. The multifilament yarn may further be in spinneret dyed form unless the textile film is to remain white anyway. In particular, the warp and/or weft threads can be formed, in particular spun, from polyester fibers. Preferably, both the warp and the weft are formed of polyester fibers, since a suitable choice of material ensures the achievement of durability and the desired mechanical properties. In principle, however, it is also possible to use monofilament yarns. Alternative plastics and fibres are also possible, for example fibre materials made from acrylate or polyethylene derivatives (if applicable) or with or from glass fibres.
The thickness of the film can basically be chosen within a wide range, depending on the weight class and the strength required. It is advantageous if the thickness of the film is from 500 μm to 1300 μm, preferably from 600 μm to 1200 μm, in particular from 700 μm to 1000. mu.m. On the one hand, the required strength can be achieved within the respective thickness range. On the other hand, in this case, the woven film is not so thick as to cause architectural difficulties or require special structures at the time of installation. In particular, a thickness range of 700 μm to 1000 μm has been confirmed as the optimum range.
The grammage of the film is at least 600gm-2Preferably 700gm-2-1800gm-2. The corresponding grammage is in turn determined by the type of requirements in the construction application, and in combination with the thickness of the textile film described above, it is necessary to take care of the required strength and construction application, which can be configured in a simple manner.
The fabric layer may be provided with a coating on both sides. In particular, the coating may be formed from a PVC coating layer. These coatings are preferably applied to both sides of the fabric layer, although it is also conceivable to provide only the outer side of the fabric layer, which is exposed to weather conditions during later use, with a corresponding PVC coating.
In order to seal the textile film on the outside, a lacquer layer can be applied to each PVC coating layer. The coating layer may consist of a plurality of layers, in particular a backing layer and a top coat layer covering the outside thereof.
The textile films according to the invention are used for all conceivable construction applications. Any object, such as a building or a part of a building, may be formed with or from a film according to the invention. Preferably, a textile film is used as material for the building envelope, for example in a stadium, air dome, tent or the like. Application as a sunshade may also be preferred.

Detailed Description
Figure 1 shows a fabric layer 2 in the form of a satin weave. It can be seen that the fabric layer 2 has warp threads 21 and weft threads 22. In each case, this weft thread 22 passes under 4 warp threads 21 before the weft thread 22 crosses over one warp thread 21 and then passes under 4 warp threads 21 again. The respective intersections (binding points) of the weft threads 22 and the warp threads 21 are offset from each other (consecutive number).
The respective fabric layer 2 is the center, and therefore the central component, of the textile membrane 1, which is shown schematically in cross-section in fig. 2. The membrane 1 has a fabric layer 2 in the form of a satin weave. In particular, this may be a five-strand or eight-strand satin weave. The central fabric layer 2 is surrounded on both sides by PVC coating layers 3. The PVC coating 3 is in turn covered on the outside by a lacquer layer 4, which seals the textile film 1 on the outside. Overall, this results in a multilayer structure of the textile film 1. The respective PVC coating layer 3 can be applied several times. In the case of multiple applications, it is possible for the individual PVC coating layers 3 to have at least partially different compositions. For example, the inner PVC coating layer 3 adjacent to the central fabric layer 2 may be formed with a different composition than the outer PVC coating layer 3 and then adjacent to the paint layer 4 for tight bonding purposes. In addition to the usual auxiliaries and additives, such as plasticizers, stabilizers or fillers and flame retardants, the PVC coating layer 3 generally comprises in particular: titanium dioxide and/or other white or colored pigments. However, the PVC coating layer 3 is formed without phthalate. The thickness of the membrane 1 is typically in the range of 600 μm to 1200 μm.
With reference to fig. 3 and 4, the advantages of a five-harness satin weave in the textile membrane 1 compared to the panama weave 2/2 of the prior art can be explained. As can be seen from fig. 3, the weft threads 22 first pass over the warp threads 21, then under 4 warp threads 21, until finally the weft threads 22 pass over the warp threads 21 again. In contrast, according to fig. 4, the panama knit 2/2 shows 1 distinctly wavy weft thread 22, since it usually passes more upwards over 2 warp threads 21 and then passes again under 2 warp threads 21. Due to this pronounced wavy shape of the weft threads 22 in the finished state, a given limitation of the thickness of the textile film 1 leaves considerably less space for the application of the PVC coating layer 3. In other words, the PVC coating layer 3 cannot be formed to the same thickness as in the case of the satin weave described in fig. 3. In this respect, it has surprisingly been found that the required strength can also be achieved by satin weaving, and furthermore, there is a clear advantage in forming a thicker PVC coating layer 3, thus allowing better weather resistance to be achieved. In other words, it can also be said that a thinner (raw) fabric can obtain the same mechanical properties, i.e. due to the increased thread count.
In comparison with fig. 4, it can be seen from fig. 3 that the weft threads 22 have less wave-like formation in their course, so that the elongation behavior is also significantly improved. In fig. 5, the corresponding measurement results are shown. It can be seen that in the case of the panama weave 2/2, the difference between the warp 21 and weft 22 is significantly greater than in the case of the satin weave.
Overall, therefore, the thickness of the PVC coating layer 3 can be optimized by the textile film 1 with satin weave according to the invention, achieving the required strength and meeting other building parameters, while the elongation properties are improved due to its low degree of asymmetry. Finally, another result is improved light transmission behavior and good tactile feel, since the outer surface is formed smoother than in the case of the prior art.
