At least one surface of the surface coating is then painted, the paint system of the coating containing as the primary binder an ethylene-vinyl acetate copolymer with a vinyl acetate content of 25-55% by weight and one or more thermoplastic acrylate resins.
- the paint system used is preferably a solution and not an (aqueous) dispersion, as described, for example, in JP 2001 310424 A. It has been shown that not only must a certain proportion of vinyl acetate be contained in the paint system, but that the system also requires organic solvents so that the required properties can be maintained in the end product. In addition to the kink resistance mentioned above, this also includes good adhesion Paint system on the coating with good high-frequency weldability of the entire system.

Drying takes place at approx. 80°C for approx. 1 minute (per layer). Higher drying temperatures can improve paint adhesion, but are usually limited by the softening temperature of the substrate.
- FIGS. 4a and 4b each show photographs of a sample 3 and a sample 4, whereby in sample 3 a textile fabric with a coating according to claim 1 and another textile fabric with a coating made of polypropylene were welded using hot air and sample 4 a hot air welding of a textile Fabric according to claim 1 with a further textile fabric with a coating made of polyethylene.
- Figures 5 and 6 show electron micrographs of textile fabrics that were processed using high-frequency welding, the textile fabrics having a paint finish according to the invention and no paint finish according to the invention.
- Figure 1 shows both samples 1 and 2, where the carrier material in both cases was a fabric.
- the carrier material in both cases was a fabric.
- the adhesion value is determined using the ISO 2411:2017 (EN ISO 2411:2017) standard, with the second method the sample preparation of the standard should be applied and the values should apply to measurements of test specimens that are measured in the machine direction (i.e. in the warp direction).
- a sample 3 was formed from a textile fabric according to claim 1 and a further textile fabric with a coating made of polypropylene. Using hot air welding, an adhesion value of more than 50 N/cm could be achieved without edge waviness.
- a sample was formed from a textile fabric according to claim 1 and a further textile fabric with a coating made of polyethylene.
- a connection could be achieved by hot air welding which has an adhesion value of at least 50 N/cm without producing edge waviness.
- the adhesion value is determined using the standard ISO 2411:2017 (EN ISO 2411:2017), whereby the second sample preparation method of the standard should be used and the values of test specimens that are measured in the machine direction (i.e. in the warp direction) should apply .
- 5 shows an electron micrograph of the cross section of a textile fabric with a coating of polyethylene and ethylene vinyl acetate copolymer without a coating according to the invention
- Figure 6 an electron micrograph of the cross section of a textile fabric of the same material with a coating according to the invention can be seen.
- the carrier material and coating material were the same for both textile fabrics from Figure 5 and Figure 6 and as defined in claim 1, only the paint was different. Both textile fabrics were processed using high-frequency welding under the same conditions. In both cases, a painted and a non-painted side were welded together.
- the adhesion between the surface coating and the paint after welding is essential and can also be shown in the images in Figures 5 and 6.
- the carrier material with the surface coating (same materials as in Figure 6) was painted with a PVC-free paint system (which is not according to the invention).
- the PVC-free paint was not specifically tailored to the surface coating.
- Figures 7 and 8 show electron microscopic images of the cross section of textile fabrics that were processed using high-frequency welding, the textile fabrics being a PVC-free tarpaulin according to the invention with a PVC-free paint and not being a PVC-based tarpaulin according to the invention with PVC-containing paint represents (benchmark).
- Figure 7 shows the same carrier material painted with a paint system according to the invention as in Figure 6 and as shown in claim 1.
- two painted layers were welded together using high-frequency welding and not, as in Figure 6, a painted layer with an unpainted layer.
- the weld seam can be clearly seen in Figure 7 in contrast to Figure 6, but here too there are no cavities along the weld seam, but rather a flat connection of the two layers across the interfaces.
- the fact that no weld seam can be seen in Figure 6 as in Figure 7 does not mean that there is no weld seam in Figure 6. Since in Figure 6 only one of the two welded layers was painted, this could result in the electron microscopic image having too little contrast to recognize the weld seam.
- FIG 8 shows a PVC-containing carrier material with a PVC-containing paint system not according to the invention.
- This system represents a benchmark that has previously been used as standard tarpaulin material.
- two coated layers were connected using high-frequency welding.
- the PVC-based system in Figure 8 is like that In the PVC-free system according to the invention from Figure 7, a clear weld seam can be seen, along which no cavities, but a closed connection of the layers, can be seen.

Abstract
L'invention se réfère à un tissu textile comportant une couche de support ainsi qu'à la production et à l'utilisation de celui-ci, la couche de support comprenant des fibres de polyéthylène et/ou de polyester. Un revêtement de surface est appliqué sur au moins une des surfaces de la couche de support, le revêtement de surface étant constitué d'au moins un mélange de polymères, le mélange de polymères comprenant au moins un mélange de polyéthylène (PE) et de polyéthylène-acétate de vinyle (PEVA), la proportion de polyéthylène-acétate de vinyle du mélange de polymères étant d'au moins 40 % en poids sur la base du poids total du mélange de polymères. Le revêtement de surface comporte une couche de peinture, la peinture de la couche de peinture contenant, en tant que liant primaire, un copolymère d'éthylène-acétate de vinyle dont la teneur en acétate de vinyle est de 25 à 55 % en poids, et une ou plusieurs résines d'acrylate thermoplastique, la proportion d'acétate de vinyle du mélange de polymères étant de 15 à 30 % en poids. L'invention divulgue également un système de peinture pour revêtir le tissu textile de peinture.
