Description

Title of the invention: Vegetated textile complex, method of manufacturing such a complex, sun and / or rain protection device comprising such a complex, and use of said complex to manufacture said device. technical field

[0001] The present invention relates to the technical field of plant-based textile complexes, methods of manufacturing such complexes, sun and / or rain protection devices comprising such complexes, and the use of plant-based textile complexes for the manufacture of said devices. State of the art

[0002] Cities today are the places that concentrate the most sources of air pollution, resulting in urban heat islands, which limit the dissipation of pollutants. This pollution has harmful effects on the population. It is therefore necessary to improve existing pollution control strategies, or even develop new ones, to achieve a healthier environment in a sustainable manner.

[0003] Plants are known for their pollution-reducing properties and for their ability to mitigate temperatures, and therefore heat peaks.

[0004] In recent years, a marked increase in the number of heat waves in France, and particularly in large cities, has been observed. This is known as the urban heat island effect, characterized by a significant rise in air temperature. Mitigating these temperatures is therefore a major challenge. Among the strategies identified, greening urban spaces represents an effective lever. Indeed, plants act through two different mechanisms: evapotranspiration and water evaporation. During periods of intense heat, plants absorb heat and cool the air by releasing water vapor. Plants also create natural shaded areas by reflecting sunlight, thus transmitting only about 20% of the sun's rays—for example, in the case of an average tree. Plants therefore play a protective role by intercepting a portion of the sun's rays.

[0005] It is therefore regularly undertaken to plant trees to green cities and create pockets of coolness. The plants selected must, however, be easy to maintain, consume little water, and adapt to the weather conditions of the region in which they are planted.

[0006] Urban greening is also undertaken by planting vegetation on walls and roofs. It has been observed that vegetation acts as a solar barrier by reducing the surface temperatures of the buildings that incorporate it.

[0007] There is therefore a need for a support that improves urban greening, is simple to use, easy to assemble, lightweight, durable and easy to maintain. Description of the invention

[0008] The present invention overcomes all or part of the aforementioned problems in that it relates to a plant-based textile complex comprising, in particular, essentially: - a textile support comprising an inner and an outer face, said outer face being waterproof and water-repellent; and - at least one vegetated assembly comprising a layer of at least one plant moss and a flexible substrate having internal and external faces, said layer of at least one plant moss being disposed on the external face of the flexible substrate; and

[0009] - a fastening means, in particular a polymeric bonding layer, disposed between the inner face of said substrate of said vegetated unit and a region of the outer face of the textile support and securing said at least one vegetated unit with the textile support.

[0010] The inventors determined that plant mosses were the most suitable plants for combination with a flexible textile support. Indeed, plant mosses have good resistance to urban conditions (pollution, exposure, rain, wind, etc.), do not require soil or roots, nor a fertilizing or nutrient layer, making them a light and manageable plant substrate.

[0011] Advantageously, it was observed at the end of a year of testing the vegetated textile complex subjected to external weathering that the plant mosses remained alive while exhibiting a good appearance, and that the textile support retained its initial properties of impermeability, water repellency, its aesthetic properties, and could be cleaned.

[0012] Advantageously, the plant-based textile complex is flexible in that it can be folded over itself or rolled up on itself. However, this operation is not intended to be repeated because the vegetated textile complex could be damaged. Indeed, the thickness of the vegetated textile complex is not uniform and is greater than the thickness of the textile support alone. Furthermore, the plant mosses need light and water to survive, so they must remain exposed to sunlight.

[0013] Said fastening means may include a mechanical fastening means, in particular complementary male and female attachment means allowing for fixed or reversible fastening, for example with loops and hooks, or even a seam, in particular distributed between the region of the external face of the textile support to be vegetated and the internal face of the flexible substrate of the vegetated assembly(ies).

[0014] Preferably, said means of securing is a means of securing configured to allow securing between the external face of the textile support and a vegetated assembly whose implementation does not require heating the vegetated assembly to a temperature greater than or equal to 50°C or 45°C or 40°C or 35°C.

[0015] Preferably, the bonding means is a polymeric bonding layer.

[0016] Advantageously, a plant-based foam can be bonded to a waterproof and water-repellent textile support by means of a polymer bonding layer.

[0021] Preferably, the external face of the vegetated textile complex is not totally covered by one or more plant mosses.

[0022] Advantageously, the outer face of the vegetated textile complex includes at least one area of ​​its outer face free from a vegetated assembly.

[0023] In a preferred embodiment, the plant-based textile complex has a maximum thickness of between 0.5 cm and 30 cm or 15 cm, preferably between 1 cm and 10 cm or 15 cm, even more preferably between 1 cm and 5 cm, more particularly a thickness of between 0.5 cm and 3 cm, even more particularly between 1 cm and 1.5 cm.

[0024] The maximum thickness of the vegetated textile complex is understood to be the maximum thickness that can be measured between the internal and external faces of said vegetated textile complex.

[0025] Advantageously, the vegetated textile complex does not include soil and / or roots and / or fertilizing substrate and / or a watering device.

[0026] Advantageously, the maintenance of life of the layer in at least one plant moss is ensured by the natural surrounding conditions (rain, wind,...).

[0027] In one embodiment, the polymer bonding layer is transparent or translucent. This arrangement allows visualization of the outer face of the textile support when said outer face of the plant-based textile complex does not include a plant assembly.

[0028] In one embodiment, the region(s) of the external face not comprising plant foam also do not comprise a polymeric bonding layer.

[0029] Advantageously, the plant-based textile complex includes one or more means of bonding, in particular one or more polymeric bonding layer(s), disposed between the inner face(s) of the flexible substrate(s) and one or more regions of the outer face of the textile substrate. Textile support

[0031] Advantageously, the textile support comprises substantially opposite internal and external faces.

[0032] Preferably, the external face of the textile support is oriented towards the said means of bonding, in particular towards the polymeric bonding layer(s).

[0033] The inner surface of the textile support can be oriented towards the environment, in particular directly towards a reception area intended to accommodate one or more persons and / or one or more objects to be protected from sunlight and / or rain. Preferably, in this case, the inner surface opens directly into the environment, so that a layer of air, in particular more than 15 cm thick, is in direct contact with the inner surface of the textile support.

[0034] The inner face can also be oriented with respect to a support structure, for example when used as a cover for an element of street furniture.

Preferably, the thickness of the textile support is the distance between its inner and outer faces.

[0043] The outer surface of the textile support is advantageously waterproof and water-repellent. This arrangement prevents leaves and dust from adhering to it, and prevents water from stagnating on the outer surface of the textile support, and therefore on the outer surface of the vegetated textile complex.

[0044] In addition, the waterproofing and water-repellent primer, possibly combined with the polymeric bonding layer in the area or areas comprising a vegetated area, forms a waterproof barrier and protects the textile against the possible penetration or migration of said at least one moss.

[0045] Advantageously, the inner face of the textile support does not include any plant material (soil, roots, foliage, etc.) or plant moss.

[0046] Preferably, the measurement of impermeability and water repellency can be carried out according to ISO 811, dated 2018, and entitled "Textiles - Determination of resistance to water penetration - hydrostatic pressure test".

[0047] In the present text, waterproof means that water cannot pass through the textile support from its outer face to its inner face.

[0048] In the present text, water-repellent means that water does not stagnate on the external face of the textile support, but that its runoff, its sliding along the external face of the textile support is facilitated.

[0049] Waterproofing and water repellency of the outer surface of the textile substrate can be achieved by any technique known to those skilled in the art. For example, by applying an aqueous dispersion or an aqueous solution, comprising polyurethane or a silicone polymer, to the outer surface of the textile. The water is then evaporated, and a layer or finish is formed on the outer surface of the textile.

[0050] Preferably, the waterproof and water-repellent coating or finish is transparent or translucent. Advantageously, the textile of the textile support is visible from the outer face of said textile support. Polymer bonding layer

[0051] The polymeric bonding layer comprises at least one polymer enabling a chemical and / or mechanical bond between the inner face of the substrate and the region of the outer face of the textile support.

[0052] Preferably, the polymeric bonding layer penetrates partially into the thickness of the flexible substrate of a vegetated assembly and / or into the thickness of the textile support, even more preferably ensuring a mechanical bond by being intertwined with the inner face of said flexible substrate and / or the outer face of the textile support.

[0053] Preferably, the polymer bonding layer also forms chemical bonds with the outer face of the textile support and / or the inner face of the flexible substrate, for example hydrogen bonds, covalent bonds, Van Der Waals bonds, or a combination thereof, and possibly mechanical bonds if it can partially coat the outer face of the textile support.

[0054] Preferably, the polymer binder can be any binder chosen by a person skilled in the art that ensures the bond with the outer face of the textile support and the inner face of the substrate.

[0055] The plant-based textile complex may comprise a substantially continuous polymer bonding layer covering the entire outer surface of the textile support, or a discontinuous layer covering only one or more regions of the outer surface of the textile support, each receiving a plant-based assembly. In the latter case, several polymer bonding layers are obtained.

[0056] Preferably, in all cases, a polymeric bonding layer is found between the outer face of the textile support and the substrate of a vegetated assembly.

[0061] Said at least one plant moss also has the advantage of being resistant to weathering and to ultraviolet (UV) rays.

[0062] Advantageously, a plant-based moss is non-invasive. Thus, if a region of the outer surface of the textile support is not covered with a plant-based layer, it will not be colonized / invaded by the neighboring plant-based moss and will remain intact. This arrangement allows for variation in the aesthetic appearance of the outer surface of the complex. plant-based textiles.

[0063] Advantageously, the external face of the vegetated textile complex comprises one or more vegetated zone(s) (in particular each comprising a vegetated unit) with one or more non-vegetated zone(s) (in particular not each comprising a vegetated unit).

[0070] Advantageously, the layer comprising at least one plant moss may comprise several different plant mosses, in particular chosen from list I and / or list II.

[0071] The flexible substrate, in particular its textile auxiliary layer defined below, comprises, or may be, a textile or a felt, for example a geotextile.

[0072] Advantageously, the flexible substrate(s) of the vegetated assembly(ies) is / are non-putrescible.

[0073] The flexible substrate, in particular its auxiliary textile layer defined below, comprises, or may be, a felt, for example wadding

[0074] In one embodiment, the flexible substrate, in particular its auxiliary textile layer defined below, comprises, or is essentially made of, one or more synthetic materials, for example polypropylene, polyesters (PET, PBT, etc.), polyethylene, or a combination thereof. Advantageously, in this case, the synthetic substrate absorbs and retains less water and therefore adds less weight to the vegetated textile complex when it rains. Furthermore, the water evaporates more quickly.

[0075] In one embodiment, possibly in combination with the preceding embodiment, the substrate comprises, or is essentially made up of, one or more water-absorbing materials, for example, cellulosic materials, in particular cotton, bamboo, etc. Advantageously, in this case, the substrate absorbs and retains water. More water will evaporate into the surrounding environment in this latter case.

[0076] The choice of substrate depends on environmental conditions (dry or humid) and the season. Use(s)

[0077] The vegetated textile complex can be used in the construction of an element of street furniture, such as a bus shelter, an outdoor blind (for example the blind of a terrace), the roof of a kiosk, on the facade of a building; a pergola; or in the construction of a classic piece of furniture used indoors, for example for an interior blind.

[0078] In one embodiment, the ratio of the total surface area occupied by one or more vegetated unit(s) Svg (cm2) to the total surface area (cm2) of the external face of the textile support is less than or equal to 0.70; preferably less than or equal to 0.50; even more preferably less than or equal to 0.45 or 0.40 or 0.35.

[0079] The total surface area occupied by one or more vegetated unit(s) Svg (cm2) is the total surface area of ​​the external face of the textile support which is occupied by said or said vegetated unit(s).

[0080] In one embodiment, the vegetated textile complex comprises one or more vegetated unit(s), and the ratio of the total surface area occupied by one or more vegetated unit(s) Svg (cm2) to the total surface area (cm2) of the external face of the textile support is greater than or equal to 0.20 and less than or equal to 0.40 or 0.45; in particular greater than or equal to 0.25 and less than or equal to 0.35.

[0081] The inventors have determined that, given the flexibility and lightness of the textile support, the external face of the textile support should not be totally covered by one or more plant assembly(ies) so that the textile support can withstand the weight of the wet plant assembly(ies), and thus does not sag and preserves its mechanical properties and aesthetics.

[0082] In one embodiment, the ratio of the total surface area of ​​the region(s) of the external face receiving one or more vegetated assembly(ies) Svg (cm2) on the total surface (cm2) of the external face of the textile support is greater than or equal to 0.20 and less than or equal to 0.40 or 0.45; in particular greater than or equal to 0.25 and less than or equal to 0.35.

[0083] Indeed, a layer of vegetated moss(es) can carry up to more than three times its dry mass in water.

[0084] Thus, in rainy weather, the weight of the vegetated textile complex could be multiplied by two, or even by three if the textile support was totally covered with vegetated assembly(ies).

[0085] In one embodiment, the layer of at least one plant moss is entangled at least partially through the substrate.

[0086] Advantageously, the plant moss is mechanically attached to the substrate.

[0087] In one embodiment, the substrate comprises a grid or a layer comprising through openings having at least a dimension greater than or equal to 1 mm, and optionally comprising further an auxiliary textile layer or a felt.

[0088] The grid or perforated layer promotes the anchoring of the plant moss through the openings. The auxiliary layer allows for varying levels of water retention and facilitates handling of the moss layer(s).

[0089] In one embodiment, the substrate comprises a felt, a non-woven fabric, or a combination thereof.

[0090] The felt or non-woven fabric comprises one or more synthetic material(s) and / or one or more natural material(s), in particular cellulosic.

[0091] The nonwoven fabric may be needle-punched, hydrobonded, or thermally bonded, in particular comprising synthetic fiber(s) and / or hydrobonded and / or needle-punched and / or thermally bonded cellulose fiber(s). This type of nonwoven fabric has a greater thickness than nonwoven fabrics obtained by meltblown production. This mat thus ensures good water absorption and retention for the plant-based foam.

[0092] Advantageously, the plant moss(es) is / are cultivated directly on the flexible substrate, which promotes its adhesion to the substrate. The substrate must therefore have a certain thickness to allow this cultivation, for example, on the order of 3 mm to 10 mm.

[0093] In one embodiment, the vegetated textile complex comprises a first vegetated set and a second vegetated set separated from each other by an area of ​​said vegetated textile complex not comprising a vegetated set, in particular the external face of the textile support, possibly coated with the polymeric bonding layer, is visible in said area.

[0094] Advantageously, the area(s) of the external face of the vegetated textile complex not comprising a vegetated assembly allows the external face of the textile support to be revealed.

[0095] Thus, the pattern(s) and / or the color(s) of the textile support, possibly obtained by printing, dyeing and / or by the use of colored thread(s), are visible from outside the complex.

[0096] The outer face of the textile support can be in a solid color, for example in a dark color.

[0097] In one embodiment, the vegetated textile complex comprises a first portion of its external face comprising a layer in at least one plant foam and at least a second portion of its external face from which the external face of the textile(s) of the textile support is visible.

[0098] In one variant, the textile support comprises a fabric.

[0099] In one embodiment, the textile support is a jacquard fabric comprising at minus two wires of different colors.

[0100] In one embodiment, the textile support is a fabric whose color is substantially uniform.

[0101] Advantageously, a fabric comprises warp and weft yarns and exhibits good mechanical resistance and low elongation naturally, which helps to avoid deformations.

[0102] Preferably, said fabric has an elongation at break in the warp direction and / or in the weft direction greater than or equal to 20% or 30% and less than or equal to 80% or 60%.

[0103] Advantageously, the textile support, in particular the fabric, does not include elastic yarn, that is to say yarn having an elongation at break greater than or equal to 60%, in particular greater than or equal to 80% or 120%.

[0104] In one embodiment, the textile support has a surface mass less than or equal to 400 g / m2, preferably less than or equal to 300 g / m2.

[0105] In one embodiment, the plant-based textile complex has a surface mass less than or equal to 2000 g / m2, preferably less than or equal to 1500 g / m2, even more preferably less than or equal to 1200 g / m2 or 1000 g / m2.

[0106] According to a second aspect, the invention relates to a method for manufacturing a plant-based textile complex, in particular according to any one of the embodiments referred to in the first aspect of the invention, said method comprising the steps, in particular in this order: (i) provide a textile support comprising an inner and outer face, said outer face being waterproof and water-repellent; and (ii) provide at least one vegetated assembly comprising a layer of at least one plant moss and a flexible substrate having internal and external faces, said layer of at least one plant-based moss being arranged on the outer surface of the flexible substrate; and (iii) apply a dispersion or solution, including an aqueous solution, comprising at least one polymer, to at least one region of the outer face of the textile support and / or to the inner face of the flexible substrate of said vegetated assembly, and then place said vegetated assembly in contact with said region of the outer face of the textile support; and (iv) dry said dispersion or applied solution at a temperature less than or equal to 50°C, in particular at room temperature, to bond said plant assembly with the textile support and form a polymeric bonding layer between the inner face of the flexible substrate of said plant assembly and the region of the outer face of the textile support.

[0107] Preferably, the drying time is greater than 30 min, in particular greater than or equal to 2h, more preferably between 3h and 20h, preferably between 3h and 12h, possibly between 3h and 5h.

[0108] Preferably, the dispersion or solution, in particular aqueous, has a mass dry extract greater than or equal to 30% or 35% or 40%, even more preferably greater than or equal to 50%.

[0109] This arrangement makes it possible to reduce drying time.

[0110] Indeed, it is not possible to accelerate the formation of the polymeric bonding layer by heating, electron bombardment or exposure to UV rays, or by infrared heating, because this would destroy the plant moss.

[0111] Step (ii) may include the supply of several vegetated assembly(ies).

[0112] In one embodiment, the dispersion or solution is applied according to the internal face(s) of the flexible substrate(s) of the vegetated assembly(ies) and / or according to one or more determined region(s) of the external face of the textile support.

[0114] Advantageously, said process includes a step of cutting the vegetated assembly(ies) according to one or more determined shape(s) (for example parallelepiped, oval, circular, ...), in particular during step (ii).

[0115] In one embodiment, the outer face of the textile support includes at least one visually identifiable region, and the vegetated assembly, in particular having a shape similar to the shape of said region, is arranged in said region.

[0116] Advantageously, said at least one region has a perimeter which is drawn, in particular obtained by printing or by weaving the textile, in particular by jacquard weaving of said textile.

[0117] Advantageously, the surface fraction of said region of the external face in relation to the total surface of the external face of the textile support is less than or equal to 60%, in particular less than or equal to 50%, more particularly less than or equal to 40%.

[0118] Advantageously, the outer face of the textile support can include several visually identifiable regions, thus forming indications for the arrangement of the vegetated sets.

[0119] Advantageously, the outer face of the vegetated textile complex combines at least one area having a first pattern free of plant moss with at least one vegetated area. This arrangement provides numerous possible aesthetic effects for the complex.

[0120] The invention relates, according to a third aspect, to a sun and / or rain protection device, in particular a sun and / or rain protection blind or a flexible sun and / or rain protection panel, comprising the vegetated textile complex according to any one of the embodiment variants with reference to the first aspect of the invention or comprising the vegetated textile complex obtained by implementing the manufacturing process according to any one of the embodiment variants with reference to the second aspect of the invention, and optionally comprising a device for maintaining the vegetated textile complex in a suspended state above a reception area to be protected from sunlight and / or rain.

[0121] Preferably, the vegetated textile complex is kept suspended above a reception area for at least one person to be protected from sunlight or rain.
