Description

Film for textile structure
Technical Field
The invention relates to a film for textile structures, comprising a textile 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 textile layer.
Background
For example, the use of relatively strong fabrics as materials for building enclosures has been established architecturally. In technical terms, the corresponding fabrics are also referred to as "films" or "woven films". In addition to strength, certain elongation properties and other material properties, such films should also have a high weatherability, among other properties.
Textile films are typically coated with a polymer, typically polyvinyl chloride (PVC), to improve weatherability. The coating is applied on both sides. Subsequently, a lacquer layer is applied over the polymer coating to achieve even greater weatherability.
Heretofore, textile films have been based on fabrics based on suitably strong threads or yarns woven in a plain weave or Panama weave (Panama weave), such as a 2/2 Panama weave. The use of these weave types in textile films has the following advantages: coatings of low settings (linear density) can achieve adequate surface coverage and strength. The advantage is that it is simpler and faster to produce (in terms of knitting time) without the need for a special loom. The disadvantage to be mentioned is the limited feasibility, which depends on the linear density and thus limits the strength.
Although known textile films have inherently superior properties, it is clearly desirable to further improve the durability of such products. Furthermore, it has also proved to be disadvantageous in terms of the mechanical properties of certain applications: the elongation in the warp direction on the one hand and in the weft direction on the other hand shows a large difference, which also makes it necessary to position the textile film accordingly in accordance with the load in the installed state, or to take into account the direction-dependent inhomogeneities of the material properties in the planning phase.
Disclosure of Invention
The object of the present invention is to provide a textile film of the above-mentioned type which has substantially the same elongation properties in the yarn and in the weft, with a high weatherability.
This object is achieved by a film of the aforementioned type if the fabric layer is formed from floats 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 yarns may preferably float over at least 4 weft yarns. Preferably, a satin weave is used for this purpose.
Within the scope of the present invention, it has been realized that several improvements can be achieved by the formation of a universal textile film of satin weave or variants thereof, or in general by a float according to the definition of weft yarns on at least 3 warp threads. First, the warp and weft show considerably fewer crossover points or longer floats than plain or panama weaves, which is why a higher linear density can be selected without any problems. By satin weaving or by substitution with suitable floats, 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 of the high-construction fabric is avoided. Secondly, the formation of a fabric layer, in particular with a satin weave, also results in the fact that the difference in elongation in the warp direction or in the weft direction is significantly smaller than with a plain weave or a panama weave. Again, this is due to the fact that: the warp and weft have significantly less interlacing and therefore the elongation properties in the warp and weft directions are correspondingly reduced. In addition, the additional advantages brought by satin braiding are: due to the multi-jumper of the warp, the linear density in the warp direction and the weft direction can be increased compared with both the plain weave and the panama weave, so that improvement in mechanical properties at the same thickness can be achieved. Finally, there is also an advantage in terms of hand feel, since the surface (warp acting on the right side of the fabric, weft acting on the left side of the fabric) is significantly smoother than in the case of previous plain or panama woven textile films.
For textile films, the thread fineness may be at least 1000dtex, preferably 1100dtex or more.
For the reasons mentioned above, it is preferred that the weft threads pass over at least 4 warp threads, in particular 5-7 warp threads. In particular, to achieve the desired performance discussed in the preceding paragraph, a satin weave of five and eight strands may be used, so that the weft threads may pass over 4 or 7 warp threads before being recombined. In general, floats of warp and weft threads may be passed over, such as at least 4, such as up to 7-9 (warp) threads, depending on the weaving cycle and the selection of the consecutive number, for example in classical satin weaving threads may float on at least 4 (five harness) or up to 7 (eight harness) or more warp and weft threads, depending on the selected weaving cycle and the number of pitches. A similar effect can be achieved with a satin weave derivative (e.g. a reinforced satin weave).
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. Multifilament yarns have the desired strength. Multifilament yarns may further be in the form of spinneret dyeings unless the textile film is to remain white anyway. In particular, the warp threads and/or the weft threads can be formed, in particular spun, from polyester fibers. Preferably, both the warp and the weft are formed of polyester fibers, as a proper choice of material ensures the achievement of durability and the desired mechanical properties. In principle, however, monofilament yarns may also be used. Alternative plastics and fibres are also possible, for example, fibre materials made from acrylic esters or polyethylene derivatives, if applicable, or glass fibres or from glass fibres.
The thickness of the film can be chosen substantially within a wide range, depending on the weight level and the strength required. It is advantageous if the film has a thickness of 500 μm to 1300 μm, preferably 600 μm to 1200 μm, in particular 700 μm to 1000 μm. On the one hand, the required strength can be achieved within the corresponding thickness range. On the other hand, in this case, the textile film is not so thick as to cause difficulty in construction or require a special structure at the time of installation. In particular, a thickness in the range of 700 μm to 1000 μm has been confirmed as the optimum range.
The film has a grammage of at least 600gm -2 Preferably 700gm -2 -1800gm -2 . The corresponding grammage is in turn determined by the type of requirements in the construction application, in combination with the thickness of the textile film described above, it being necessary to pay attention to 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 of a PVC coating. These coating layers are preferably applied on both sides of the fabric layer, although it is also conceivable to provide the corresponding PVC coating only on the outer side of the fabric layer, which is exposed to weather conditions during later use.
To seal the textile film on the outside, a paint layer can be applied on each PVC coating. The coating layer may consist of a plurality of layers, in particular of a backing layer and a top coating 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 the film of the present invention. Preferably, a textile film is used as a material for building enclosures, for example in stadiums, air domes, tents or the like. The use as a sunshade may also be preferred.

Further features, advantages and effects of the invention are apparent from the examples shown below. In the referenced figures:

FIG. 2 is a schematic cross-sectional view showing a membrane of the present invention;
FIG. 3 shows an optical microscope image of a film according to the invention (satin five harness);
FIG. 4 shows an optical microscope image of a membrane (Panama 2/2) according to the prior art;
fig. 5 shows a graph of elongation measurements.
Detailed Description
Fig. 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, before the weft thread 22 passes over one warp thread 21, this weft thread 22 passes under 4 warp threads 21 and then passes again under 4 warp threads 21. The individual crossing points (binding points) of the weft threads 22 and warp threads 21 are offset (consecutive number) from each other.
The respective textile layer 2 is the center of the textile film 1 and thus a central component, which is shown in a schematic cross-sectional view in fig. 2. The membrane 1 has a fabric layer 2 in the form of a satin weave. In particular, this may be a satin weave of five or eight strands. The central fabric layer 2 is surrounded on both sides by PVC coating 3. The PVC coating 3 is in turn covered on the outside by a paint layer 4, which seals the textile film 1 on the outside. Overall, this results in a multilayer structure of the textile film 1. Each PVC coating 3 can be applied multiple times. In the case of multiple applications, it is possible for the individual PVC coating 3 to have at least partially different compositions. For example, for the purpose of tight bonding, the inner PVC coating 3 adjacent to the central fabric layer 2 may be formed with a different composition than the outer PVC coating 3, and then adjacent to the paint layer 4. In addition to usual auxiliaries and additives, such as plasticizers, stabilizers or fillers and flame retardants, the PVC coating 3 generally comprises in particular: titanium dioxide and/or other white or colored pigments. However, the PVC coating 3 is formed without phthalate. The thickness of the film 1 is typically in the range of 600 μm to 1200 μm.
Referring to fig. 3 and 4, the advantages of the five-harness satin weave in the textile film 1 compared to the panama weave 2/2 of the prior art can be explained. As can be seen from fig. 3, the weft thread 22 passes over the warp thread 21 first and then under 4 warp threads 21 until finally, said weft thread 22 passes over the warp threads 21 again. In contrast, according to fig. 4, panama weave 2/2 shows 1 distinctly wavy shaped weft thread 22, since said weft thread normally passes more upwards over 2 warp threads 21, then passes again under 2 warp threads 21. Due to this pronounced wavy shape of the weft thread 22 in the finished state, a given limitation of the thickness of the textile film 1 leaves considerably less room for the application of the PVC coating 3. In other words, the PVC coating 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 that, in addition, there is a clear advantage in forming a thicker PVC coating 3, thus allowing better weatherability to be achieved. In other words, it can be said that the same mechanical properties can be obtained with thinner (raw) fabrics, i.e. due to the increased pick-and-place density.
As compared with fig. 4, it can be seen from fig. 3 that the weft thread 22 progresses with less wavy shape formation, so that the elongation properties are also significantly improved. In fig. 5, the corresponding measurement results are shown. It can be seen that in the case of panama weave 2/2, the difference between warp 21 and weft 22 is significantly greater than in the case of satin weave.
In general, therefore, the thickness of the PVC coating 3 can be optimized by the textile film 1 with satin weave according to the present invention, achieving the required strength and satisfying other building parameters, while at the same time the elongation properties are improved due to its smaller degree of asymmetry. Finally, another result is improved light transmission behavior and good tactile sensation, since the outer surface formed is smoother than in the case of the prior art.
