Description

Container and use thereof

Technical Field

The present invention relates to a container according to the preamble of claim 1 and its use.

Background

Containers of this type can be used in various ways, for example as filters or for protection or for transport in hydraulic engineering, coastal protection or civil engineering, in particular in road construction. Thus, the container is filled with material, such as sand, concrete or stone, and may be unloaded and positioned at a desired location depending on the use. In the respective position, the filled container can be used, for example, to protect or to depress objects under water. Furthermore, the filled container may be used for straightening purposes, for example, in order to lay a pipeline in an otherwise uneven ground. Also, such filled containers may be used to hold back water in coastal protection or in flood control accordingly.

For this purpose, conventional containers comprise a package which may be made of, for example, a synthetic polymer (plastic), such as polyester, polypropylene or polypropylene fibers, whereby synthetic fibers may be used or, for example, synthetic coatings may be used. Due to ageing and damage to the packaging, small particles of synthetic polymer may separate when using such containers made of plastic material, resulting in a large number of particles reaching rivers and oceans when used in hydraulic engineering. Even when the container is used on land, the plastic particles may separate and thus be released into the environment. This leads to undesirable environmental pollution.

To counteract this, it is proposed in document EP 3327201 a1 to use geotextiles or respectively mineral fibers containing natural fibers, basalt fibers, glass fibers or mixtures thereof as material for container wrappers. These mineral fibers are suitably coated, for example, by immersion in a liquid coating material or respectively coating solution. Such a coating may prevent wear during use of the container, thereby providing protection against wear. The coating itself is made of natural material so that even when it is subjected to wear, there will be no environmental pollution caused by synthetic materials. The package is thus made of plastic-free and coated yarn.

It has become apparent that mineral fibres, when untreated and insufficiently protected, in many cases cannot withstand the manufacture of packages (in particular to make mechanically knotted nets) without damage, and the loads experienced in use, for example nominal loads involving several tonnes. This is mainly due to the properties of the corresponding mineral fibres, in particular the high brittleness of the material which has a negative effect on the lifetime. The properties of the mineral fibres may lead to, for example, impairment of the mechanical stability of the container, since the mineral fibres of the wrapper are very closely put together in certain areas, in particular are knotted to a net or provided with another textile structure (woven fabric, fleece, woven fabric), so as to shrink under the load of the filler. Thus, the nominal minimum bending radius of the mineral fibers is insufficient, resulting in fracture of the brittle material.

Furthermore, mineral fibres may be damaged by brittleness when being fed to or, respectively, when being processed in an automatic web machine, in particular on deflectors, loops and other guides, which is why the production speed has to be reduced to allow continuous processing. This results in an increase in manufacturing time and thus in manufacturing costs.

Disclosure of Invention

It is therefore an object of the present invention to provide a container which can be manufactured quickly and affordably, while providing high abrasion resistance and high mechanical stability, in particular fracture resistance under load, and while providing high environmental compatibility.

This object is achieved by a container according to claim 1. Preferred further developments are specified in the dependent claims.

Thus, according to the invention, it is provided that the container comprises a wrapper made of yarn, wherein the sheath of the yarn comprises or respectively consists of at least one biodegradable sheath fiber (e.g. natural fiber and/or biodegradable plastic fiber) and mineral fibers constituting the core of the yarn, said core of the yarn being at least in certain areas (preferably completely) covered by said at least one biodegradable sheath fiber, e.g. braided, wrapped, wound, woven or the like.

In particular, the yarn and therewith also the package consist solely of mineral fibers (core) and biodegradable sheath fibers, so that an overall environmentally friendly package is formed. Thus, the particles separated from the sheath may degrade autonomously or, correspondingly, become composted in the environment. Furthermore, when natural fibers are used as the sheath fibers, a package completely free of plastic can be formed.

In addition to this, the yarn may comprise a biodegradable coating made of natural and/or biodegradable synthetic material (for example natural latex or respectively natural rubber or wollastonite or a compostable polymer) in order to additionally protect the yarn or respectively make it less fragile. Thus, natural materials are to be understood generally as meaning (in contrast to synthetic materials) materials derived from natural sources such as plants, animals or minerals. Biodegradable synthetic material is understood to mean a synthetic material capable of autonomous degradation in the environment.

Preferably, the biodegradable coating can thus be applied in such a way that the produced yarn is coated, for example by dipping into a liquid coating substance (mass) or a corresponding coating solution, or, for example, by applying and wiping the coating substance or a corresponding coating solution onto the finished packaging on the surface of the packaging.

Since only natural (sheath and core and possibly coating) and/or biodegradable or respectively compostable materials (sheath and possibly coating) are used for the packaging, the container will be very environmentally friendly, so that environmental contamination at the respective use site can be avoided. Thus, a container can be provided that can meet even strict environmental protection regulations. This makes sense, for example, if the container according to the invention is intended for use in coastal protection, civil engineering or other areas where the container may come into contact with water or groundwater. Thus, even in conditions where the package is damaged by ageing or wear, there will be no environmental contaminants contaminating the water or respectively the groundwater. However, this is advantageous even on land, since the container according to the invention does not release any environmental contaminants in use.

Thus, the container according to the invention may be particularly helpful to meet the requirements of guidelines 2008/56/EG (marine strategic framework directive) and 2000/60/EG (water framework directive), since only natural or respectively biodegradable materials are used in both the mineral fibres from which the core is made and the packages from which the mineral fibres are made.

The construction of an environmentally friendly yarn from mineral fibers constituting the yarn and at least one biodegradable sheath fiber at least partially, preferably completely, enveloping the mineral fibers has the advantage that despite the friability of the mineral fibers, the yarn retains a high mechanical elasticity, in particular the breaking strength, and the handling of the yarn can be improved. Thus, mineral fibres which themselves already exhibit a high tensile strength are protected from certain external influences which may lead to excessive bending of the mould, in particular.

In the context of the present invention, the term "wrapper" or respectively "envelope" is understood to mean that the at least one biodegradable sheath fiber forms a sheath which preferably completely surrounds the mineral fiber or respectively the core. Thus, the sheath fibers and mineral fibers do not form extensive substance-to-substance bonds, so that the sheath is located unbonded on the mineral fibers. To achieve this, the at least one sheath fiber may be wound in any suitable manner in a plurality of turns or respectively coils onto the core, and/or the core is covered by several sheath fibers by means of a mesh winding, and/or the core is braided by entanglement of a plurality of sheath fibers. However, other textiles and non-adhesive types of wrapping may also be utilized. In any case, the biodegradable sheath fiber extends around the outer perimeter (peripheral direction) of the mineral fiber, whereby the individual turns, coils, kinks, weaves, etc. of the at least one biodegradable sheath fiber are adjacent to each other in such a way that the mineral fiber is covered by the at least one biodegradable sheath fiber, preferably across its entire longitudinal extension, and thereby protected by the at least one biodegradable sheath fiber.

The packaging according to the invention therefore does not constitute a coating in the form of a liquid coating substance or, respectively, a coating solution as used in the prior art, since the at least one biodegradable sheath fiber used for the packaging does not form any bond with the mineral fibers or a correspondingly extensive substance-substance bond, which is the case, by definition, with a coating. Furthermore, the biodegradable sheath fiber used for the package is not a shapeless substance, but has and maintains a certain predetermined fiber shape, and this is the reason for the yarn as a whole to be mechanically more stable or correspondingly more durable, as will be explained in more detail below.

When using the yarn used according to the invention, the diameter of the yarn is in particular larger compared to mineral fibers which are not wrapped or are only coated, so that the bending radius of the yarn in the bending region of the wrapper (for example in the knot of a mechanically knotted net) or in the case of transverse loads originating from the environment or from fillers will necessarily be larger. The preferred bending radius can therefore be set in a targeted manner by means of the thickness of the biodegradable sheath fiber used for the packaging. This in turn significantly reduces the bending load on the mineral fibres, for example under heavy loads (when used with heavy fillers, especially in knotted nets). Thus, due to this effect, the mechanical resilience of the container can be greatly increased without the need to reinforce the actual load carrying member itself, i.e. mineral fibres, which would be complicated and expensive.

The container according to the invention has an increased tensile strength and an increased overall mechanical stability compared to containers made only from biodegradable fibers, in particular natural fibers and/or biodegradable plastic fibers, without the use of mineral fibers in the core. This is because yarns comprising only natural fibers or respectively biodegradable plastic fibers as stability carriers, if they have a considerable thickness, cannot guarantee the required stability or respectively load-bearing capacity. According to the invention, by means of mineral fibers, a stable mineral core for the packing yarn is provided, which is covered by biodegradable sheath fibers for additional increased mechanical stability or respectively strength and for protection.

Thus, by using a wrapper of biodegradable sheath fiber, a non-adhesive wrapper of fiber type can be provided, so that the mineral fibers can be bent only to a limited extent. Thus, despite the brittleness or correspondingly low breaking strength of the mineral fibers, breaking can be avoided and thus yarns with high mechanical elasticity can be provided. This is not possible with only a full-surface adhesive coating according to the prior art, which is overall more elastic and has little, if any, effect on the bending elasticity.

Furthermore, due to the non-adhesive connection between the core and the sheath, the yarn may even subsequently adapt, since the coating may be slightly displaced with respect to the core. The yarn to be processed without the package with mineral fibres according to the invention will have to be twisted or respectively interwoven or respectively cabled, resulting in a limited longitudinal displaceability of the filaments with respect to each other. However, by means of the wrapper, such twisting of the mineral fibers of the core may be omitted, which in turn improves the flexibility. Thus, the mineral fibres of the core can be wrapped in simple parallel running strings, so that not only the core and the wrapper but also the individual filaments are more easily displaced relative to each other when bent.

Furthermore, advantageously, an improvement of the manufacturing process is achieved. Due to the brittleness of mineral fibres, such fibres tend to splice (splice) when extending through industrial manufacturing equipment or correspondingly manufacturing machines. As a result, the mineral fibers wear themselves on the deflector, rings and other guides and are subject to partial breakage. With the package according to the invention with a biodegradable sheath fiber, the mineral fiber is protected against such splicing, so that it can be processed with little loss and no damage, and also in principle at a higher manufacturing speed, since the mineral fiber itself does not come into contact with the guide element. Biodegradable or respectively compostable materials for the wrapper or respectively biodegradable sheath fibers do not suffer from such damage due to the significantly higher ductility and softness. Furthermore, as indicated earlier, when the mineral fibres are on the deflector, ring and other guide, their bending is limited by the wrapping, so that there will be less breakage during manufacture.

It is also important that with the wrapper according to the invention it is achieved that the wear of the innermost mineral fibres is reduced to a minimum. A sheath wrapped with a less abrasive biodegradable sheath fiber provides a significantly increased handling flexibility, since the mineral fibers comprise a material that is very susceptible to abrasion, and the filling of the container with a non-wrapped sheath partly with a stone block with sharp edges and the subsequent handling of the filled container results in damage to the sheath.

In the container according to the invention, the wrapped sheath of the container completely surrounds the filler, preferably a strong filler, which is also naturally compatible or, respectively, environmentally compatible. This means that the package in the container according to the invention, when closed, has no opening through which the filling can leave the container. The packaging can be realized, for example, by sewing, knotting, splicing or other joining processes suitable for textiles made from one single mineral fiber or, respectively, one single yarn, or by means of sewing, knotting, splicing or joining together two different mineral fibers or, respectively, yarns or the like. Preferably, therefore, it is provided that the seam or other attachment exhibits at least 80% of the strength of the mineral fibres or respectively yarns, so as not to significantly impair the tensile strength or respectively the overall mechanical elasticity of the container.

Thus, the container or respectively the package may have the shape of a thin mat or a roll, for example. Alternatively, a mattress shape with a thickness preferably up to 80 cm may be provided. In this variant, the container can be used as a protection against mechanical influences or attacks, as well as an impermeable lining. Alternatively, it may be provided for the package to be in the shape of a horizontal or vertical hose. This may be made by joining the longitudinal edges of the container package. Thus, the open end of the hose may be closed (preferably by sewing, gluing, knotting, splicing or any other suitable means) in order to retain the filling within the package.

In such embodiments, the container may be used as a storage container, as a barrier for depositing rocks or rocks, or as a core for a dam or bank, respectively. The container comprising the package in the form of a vertical hose may be used for soil improvement or as a vertical drain. Alternatively, it may be provided in the general shape of a bag. Such bags may be used for flood control, scour protection and maintenance or embankment construction. Furthermore, the use in the form of gabions or artificial gabions (riff) is also possible.

In the shape of the net, the stone or rock block can be contained within a package, so that the container can be used as a filter. In this case, the mesh of the net is chosen such that stones cannot pass through them in order to be permanently held within the package. In this embodiment, a container is provided, the properties of which are mainly determined by the nature of the filling material, whereby a certain filtering effect can be achieved. Such a net filled with stones can be used, for example, as protection for objects or ballast, for example under water. Furthermore, the filled mesh container can be used for straightening in order to lay, for example, a pipeline or a cable above an originally uneven ground.

The filling of the container is preferably adapted to the permeability of the package. Furthermore, in hydraulic engineering, the faster the water is drained from the container, the better the stability of the container, whereby the permeability of the package is preferably at least 10 times the permeability of the filling of the container.

Preferably, it is also provided that the mineral fibers of the core are basalt fibers, glass fibers, carbon fibers or mixtures comprising these. These materials are characterized by a high degree of stability or respectively tensile strength, so that, when used in yarn cores, they can provide containers of high elasticity. In particular, when the mineral fibers are continuous filaments (i.e. fibers not first twisted) or correspondingly textile filaments, a high tensile strength can be achieved so that the load can be distributed over the entire longitudinal extension of the mineral fibers.

Preferably, it is further provided that the sheath, which is a biodegradable sheath fiber, comprises natural fibers (such as coconut, jute, hemp, cotton or flax), and/or biodegradable plastic fibers (such as compostable polymers), or mixtures thereof. Thus, highly stable natural fibers are used for the wrapper. For example, jute is one of the strongest natural fibers and, in addition, is easy to process, so that a simple manufacturing process and good mechanical elasticity can be ensured. Also, cotton is very wear resistant and tear resistant and durable in wet environments. Coconut fibers can adhere, thereby ensuring improved stackability while maintaining a high degree of positional stability of the containers with respect to each other. In addition, coconut fiber has uniform elasticity and exhibits strong sound and heat insulating properties. Furthermore, coconut fiber is not moisture sensitive and exhibits a high degree of abrasion and tear resistance. They are not easily damaged by moths.

Preferably, it is further provided that at least the mineral fibers are resistant to seawater. This means that they are made of a wide range of seawater resistant materials and are therefore only slightly affected by seawater when used in a seawater environment. Thus, the sea water resistance can be quantified, for example, in accordance with DIN standard DIN53739 or DIN53521, whereby it is possible to use other materials instead of the materials specified in the DIN standard for the biodegradable sheath fibers and/or mineral fibers, however, the inspection guidelines specified in the DIN standard remain unchanged. Thus, sea water resistance will already be achieved when the targets set in the DIN standard are met.

Preferably, it is further provided that the container comprising the filler has a total weight of at least 100 kg, in particular at least 1000 kg, for example up to 12 tons, and/or the container has a weight of between 0.5 and 10 m³The capacity of (c). Due to this weight, a container may be provided which will not be washed away when used in water and which will be able to retain its shape. But even on land, the weight of the filling ensures the structural stability of the container.

In general, the size and weight of the container may vary depending on its intended use, for example, depending on the ground to be straightened or the object to be protected.

Preferably, also provided isThe coated yarn has a thickness of at least 4.5 mm and/or at least 500 g/m²Gram weight of (c). By means of such a thickness or, respectively, such a grammage, a particularly high degree of mechanical stability or, respectively, robustness and filtration stability of the container can be advantageously achieved. In particular, the robustness and mechanical stability can be adapted to the environmental stresses prevailing in coastal areas.

Preferably, it is also provided that the yarn of the package has a tensile strength of at least 30 kN/m. This makes the container suitable for withstanding the loads imposed on the package, particularly during mechanical transport or normal use. Furthermore, it may be provided that the yarn (i.e. the mineral fibers and/or the biodegradable sheath fibers) is a UV resistant material. This can extend the lifetime, especially in case of high UV exposure in coastal areas.

Preferably, it is provided that the filling of the container comprises sand and/or concrete. This makes it possible to provide a flexible and adaptable container whose packaging will be made with a tighter mesh to avoid the filling material from leaving the container. For this purpose, for example, a density of 1.4 to 2.0 g/cm can be used³In between, whereby a particularly good stability of the container structure can be achieved.

Preferably, it may further be provided that the yarns of the package are joined in the form of a fleece, fabric, core, interwoven yarns or knitted fabric to form a mould package filled with sand and/or concrete. Due to the packaging of the yarn according to the invention, the tying and knotting points of the respective textile structure of the packaging are particularly well protected against breakage under high mechanical loads.

Preferably, it may further be provided that the yarns are joined, in particular joined, in the form of a net in order to form the package. It is thus possible to provide a filter, in particular for hydraulic engineering, whereby the mesh type packing will contain stones or the like, preferably as a filler, whereby the stones have a diameter larger than the openings or respectively the mesh of the mesh (packing) formed by the yarns. Due to the wrapping of the yarn according to the invention, the knotting points and knotting points of the net are particularly well protected against breakage under high mechanical loads and against abutting sharp stones.

According to the invention, there is also provided the use of the container according to the invention in hydraulic engineering and/or coastal protection, civil engineering, in particular road construction, or as a filter.

Hydraulic engineering is therefore understood to mean measures, technical interventions and constructions in connection with ground water, surface water and shore. Coastal protection includes especially flood control. The use in coastal protection includes in particular the use under the influence of tides or respectively under heavy sea conditions. The use for bank construction, channel protection, scour protection, securing of leads (wires, pipes, etc.) and gas securing or respectively wire and foundation protection can likewise be provided. In civil engineering, such containers can be used for separation, drainage, filtration, reinforcement or preservation. In particular, such a container may be used in offshore wind farms or the like, for example, for protecting the foundation of a wind turbine or, correspondingly, for straightening it underground so that the lead path is optimized.

Due to their filtering effect, such containers can also be used as filters, as long as the filler is chosen appropriately. Thus, preferably, it may be provided that the container is in contact with the ground, which ground comprises particles having a certain average particle size. The width of the container opening can be adapted to this average particle size in order to adapt the container to hydrodynamic stresses and fine and medium sands which are usually present at shore.

Drawings

The invention is further illustrated below by means of examples of several embodiments. In which is shown:

FIGS. 1a, 1b are schematic views of a container in various embodiments; and

figure 2 is a perspective view of the yarn of the package.

Detailed Description

Fig. 1a shows a mesh container 1 for receiving larger stones as filling material 2, and fig. 1b shows a bag container 1 for receiving sand and/or concrete as filling material 2. Besides these containers 1, which are shown as an example, other shapes and textile structures of the containers 1 can be provided, which are essentially determined by the packaging 3 of the containers 1.

Here, the packing 3 also determines which fillings 2 can be accommodated in the container 1. In principle, therefore, the coarse mesh container 1 can only be used to contain a filling material 2 made of coarser particles (e.g. stone), while the fine mesh container 1 can also contain a filling material 2 made of finer particles (e.g. sand). The type of container 1 used is therefore determined by the respective intended use, whereby, as a function thereof, the shape of the package 3 or, respectively, the size, material and properties can be determined or, respectively, adapted to the filling 2.

Wrapper 3 itself is made of yarn 4, yarn 4 being environmentally compatible. Thus, it is not mandatory to provide a biodegradable coating made of natural and/or biodegradable synthetic material in order to cause the textile structure of the yarns 4 to extend in the longitudinal direction X as shown in fig. 2. Accordingly, the yarn 4 comprises an endless mineral fiber 5 as a core and a biodegradable sheath fiber 6 covering the core, whereby the sheath fiber may be a natural fiber 6a and/or a biodegradable plastic fiber 6 b. The biodegradable sheath fibers 6 of the sheath at least almost completely surround the mineral fibers 5 of the core in both the peripheral direction U and the longitudinal direction X.

Preferably, the core or respectively the mineral fibres 5 are continuous filaments (textile filaments) which extend "endless" in the longitudinal direction X. For example, to produce the yarn 4, individual endless mineral fibers 5 are spun from a liquid rock mass (basalt rock) in a fine drawing process. Subsequently, on the outer periphery 5a of the mineral fiber 5, the biodegradable sheath fiber 6 is wound therewith in several turns or braided or knitted or wound or enveloped or the like, so that the biodegradable sheath fiber 6 completely surrounds the mineral fiber 5, thereby protecting the mineral fiber 5.

With the mesh container 1 according to fig. 1a, the yarns 4 made in this way are joined or respectively knotted in place in order to form the mesh wrapper 3. For bag-type container 1 according to fig. 1b, the manufactured yarns 4 are put together in the form of a fleece, fabric, core, interwoven or knitted fabric to form bag-type package 3. Subsequently, the filler 2 is introduced and the container 1 is closed.
