Abstract
A method for producing a textile fabric (1) with local reinforcements (4 a,4 b) and a textile fabric (1) produced by such a method are provided, wherein the local reinforcements are applied to the textile fabric (1) at positions located within pre-cut positions (D, D1, D2) which are spaced apart from each other by a distance (D1, D2) which may or may not be changed, wherein a protective stabilizing film (5) is applied to the textile fabric (1) at least in the part of the textile fabric (1) that is located in the region between two consecutive pre-cut positions (D, D1, D2) before the local reinforcements (4 a,4 b) are applied.
Description
Background
In many cases it is desirable to use textiles with localized reinforcements (such as printed or illuminated patterns) that will be created at unique and well-defined locations of the fabric obtained from previous processing steps.
However, given that most textiles are easily deformed, the interactions necessary to create the localized reinforcement may stress and cause localized strain to the fabric, which in turn causes the fabric to twist and deform and thus reduce the accuracy of the dimensional specifications of the localized reinforcement on the final product.
Disclosure of Invention
It is therefore an object of the present invention to provide a method for producing a textile fabric with localized reinforcement, which method enables a more accurate dimensional specification of the localized reinforcement, and to provide a textile fabric with localized reinforcement that is more accurately positioned.
This problem is solved by a method for producing a textile fabric with a localized reinforcement with the features of claim 1, and by a textile fabric with the features of claim 11, which method enables a more precise dimensional specification of the localized reinforcement.
According to the method of the invention for producing a textile fabric with localized reinforcements applied to the textile fabric at positions within the pre-cut location (i.e. predetermined areas of the manufactured textile fabric sheet or roll that are to be used, which may also be referred to as pre-cut areas), which are spaced apart from each other by a distance that may or may not be changed, when the fabric is attached to the end product, especially during the automated continuous production of such a product.
The essential feature of the invention is that a protective stabilizing film is applied to the textile fabric at least in the part of the textile fabric that is located in the region between two consecutive precut positions before the local reinforcement is applied.
Possibly and preferably, any kind of non-stretchable film with a glue layer on one side may be used as protective stabilizing film. For example, films from the PET (polyethylene terephthalate), PP (polypropylene), PC (polycarbonate) series may be used, but possibly other kinds of 2D protection areas, such as textiles or non-wovens with a glue layer on one side, or other kinds of sprayable, laminable fluid materials which harden and become peelable films after a drying or reticulation (curing) step may also be suitable for this purpose.
Preferably, such protective stabilizing film is applied to the entire surface of the textile roll.
According to a preferred embodiment of the method, the complete removal of the protective stabilizing film is performed after the application of the local reinforcement is completed.
According to a variant, the protective stabilizing film is applied only outside the precut position. This may provide sufficient positional stability while avoiding any disturbance of the application of the local augmentation. However, if the protective stabilizing film is (also) applied inside the precut position except for the region of the precut position where the local reinforcement is applied, better positional stability can be obtained.
The protective stabilizing film may also be applied first to the entire side of the textile fabric on which the localized reinforcement is applied, and then removed from at least the area where the localized reinforcement is applied prior to the application of the localized reinforcement.
In case a fluid applicable material is used, which hardens after a certain drying/curing time and becomes peelable, local areas without protective stabilizing films can be obtained by using a mask that locally prevents the fluid applicable material from being applied on the surface of the textile fabric, on which local areas local reinforcement is performed.
According to an advantageous embodiment of the method, the protective stabilizing film is laminated to the textile fabric using a press or a roll.
In order to obtain optimal position information, according to a preferred embodiment of the method, the positioning of the pre-cut position is monitored by means of a physical index, a camera monitoring system and/or a laser monitoring system.
The localized reinforcement may be created by the addition of materials such as printing ink, localized introduction of plastic or rubber, or welding of pattern pieces.
Alternatively or additionally, in other embodiments, localized reinforcement may also be created by surface modification, for example by cutting or etching with laser or UV radiation, thermal radiation or conduction, sandblasting, application of chemical agents, or mechanically using blades and/or tools.
Position control can be further improved if the fabric is manufactured with harder grid areas created at the boundaries and/or inside of the pre-cut locations.
The textile fabric of the invention is produced by the method according to the invention.

Detailed Description
Fig. 1 shows a schematic overview of a production line 10 for producing a textile fabric 1 with localized reinforcement. Textile manufacturing machine 2 typically provides textile fabric 1 as output from yarns that have been produced from fibers. The fabric is moved in the warp direction indicated by the double arrow, for example pulled by an electric shaft which winds the end product into a textile roll 3, thereby inducing a well-defined strain on the textile fabric.
In particular in the case of a textile roll 3 to be automatically processed, future pre-cut areas D1, D2 comprising local reinforcements separated by separation distances D1, D2 are prepared at defined locations of the length of the fabric forming the textile roll 3. The positional information thus defined allows another machine (not shown) to process the textile roll 3 and to apply pre-cut areas containing localized reinforcements in a repeatable manner to the product using the fabric with localized reinforcements. More specifically, it can be achieved in this way that the local reinforcement is oriented in the same way for each product produced by the other machine.
Fig. 2a shows a cross section of a fabric 1 of a single future precut area D. The side facing upwards in fig. 2a-2c and fig. 3a-3c is the a-side, i.e. the side of the fabric that will be visible on the final product, while the side facing downwards in these figures is the B-side, i.e. the side of the fabric that will not be visible on the final product.
As shown in fig. 2b and 2c, in a defined area a located within the future pre-cut area D, more precisely starting at a left boundary distance x from the future pre-cut area D and ending at a right boundary distance y from the future pre-cut area D, a local reinforcement 4a,4b is added at a certain position of the production line 10. In fig. 2b, the local reinforcement 4a is based on the addition of material in the pre-cut area, as is the case, for example, when a printing technique is used to create the local reinforcement 4 a. In fig. 2c, the local reinforcement 4b is created without material addition, but by removing material, which can be achieved by applying laser radiation, UV radiation, sand blasting or plasma treatment, for example. Of course, hybrid techniques based on the addition and removal of materials, respectively, may also be used to create the localized reinforcement.
Figures 3a to 3c illustrate successive intermediate stages during execution of an embodiment of the invention. In fig. 3a, a cross section of a single future pre-cut area or pre-cut location D of the textile fabric 1 is shown after the protective stabilizing film 5 has been formed on the a-side, which is the side visible in the final product. This can be done by lamination using rollers or presses in a treatment step after the manufacturing machine 2 has completed treating the textile fabric 1.
In order to prevent any adverse interference with the application of the local reinforcements 4a,4b, the protective stabilizing film 5 is then removed at least in the area A, B where the local reinforcements 4a,4b are to be applied, which results in the intermediate product shown in fig. 3 b.
The local reinforcements 4a,4b are then applied, resulting in the intermediate product illustrated in fig. 3 c. During this application, the protective stabilizing film 5 effectively limits the strains induced during the application process and thus achieves a significantly improved positional stability of the local reinforcements 4a, 4b.
Subsequently, the protective stabilizing film 5 may be removed, e.g. peeled off.
