Definitions

  • the invention relates to a container according to the preamble of claim 1 and the use of the same.
  • Such containers can be used in many ways for protection, as filters or for transport, for example in hydraulic engineering, in coastal protection or in civil engineering, in particular road construction.
  • the container is filled with a material, for example sand, concrete or stones, and can be unloaded and positioned at a desired position depending on the use. At the respective position, the filled container can be used to protect or weigh down an object, for example under water. Furthermore, the filled container can be used for straightening, for example to lay pipes on an originally uneven surface.
  • Such filled containers can also be used to hold back water in coastal protection or flood protection.
  • conventional containers have a casing which can be made of synthetic polymers (plastic), for example polyester fibers, polyacrylic fibers or polypropylene fibers, it being possible to use synthetic fibers or, for example, a synthetic coating.
  • synthetic polymers plastic
  • polyester fibers for example polyester fibers
  • polyacrylic fibers polypropylene fibers
  • synthetic fibers for example, a synthetic coating. Due to aging and damage to the casing, smaller particles of the synthetic polymers can loosen when using such containers made of plastic components, whereby large amounts of plastic get into rivers and seas when used in hydraulic engineering. Even with one use the container on land, plastic particles can be detached and thus get into the environment. This leads to unwanted environmental pollution.
  • EP 3 327 201 A1 proposes to use geotextiles or mineral fibers that have natural fibers, basalt fibers, glass fibers or mixtures thereof as the material for the envelope of the container.
  • These mineral fibers are coated in a suitable manner, for example by immersion in a liquid coating compound or coating solution. This coating prevents abrasion during use of the container and thus offers protection against wear.
  • the coating itself is made of a natural material, so that environmental pollution with synthetic materials can be avoided even if it is worn. In this way, the cover is made from a plastic-free and coated yarn.
  • mineral fibers if they are untreated and inadequately protected, in many cases do not withstand the production of the cover, in particular to mechanically knotted nets, as well as the loads during use, for example with a nominal load of a few tons. This is primarily due to the nature of the respective mineral fiber, in particular the high brittleness of the material, which has a negative effect on the long-term resistance.
  • the nature of the mineral fibers can, for example, lead to a loss of the mechanical strength of the container, since the mineral fibers of the envelope, which are very closely joined together in some areas, in particular knotted into a network or provided with a different textile structure (knitted fabric, fleece, woven fabric, knitted fabric) contract under the load of the filling. As a result, the permissible minimum bending radii of the mineral fibers are not reached, which can lead to breaks in the brittle material.
  • the mineral fibers can be damaged when they are fed to or processed in automatic net-tying machines, especially when resting on deflectors, eyelets and other guides, which is why the production speed has to be reduced to enable a continuous process. This leads to an increase in the production time and thus the production costs.
  • the object of the invention is therefore to provide a container that can be manufactured quickly and cheaply and at the same time has high wear resistance and high mechanical strength, in particular breaking strength, under load while at the same time being environmentally friendly.
  • the container has a sheath made of a yarn, wherein a sheath of the yarn has at least one biodegradable sheath fiber, for example a natural fiber and / or a biodegradable plastic fiber, or consists of this and a mineral fiber of the yarn, which forms the core of the yarn, of which at least one biodegradable sheath fiber is sheathed, for example braided, knitted, wrapped, wrapped, woven, etc. at least in some areas, preferably completely.
  • a biodegradable sheath fiber for example a natural fiber and / or a biodegradable plastic fiber, or consists of this and a mineral fiber of the yarn, which forms the core of the yarn, of which at least one biodegradable sheath fiber is sheathed, for example braided, knitted, wrapped, wrapped, woven, etc. at least in some areas, preferably completely.
  • the yarn and thus also the sheath consist exclusively of mineral fibers (core) and biodegradable sheath fibers, so that overall an environmentally friendly sheath is created. Particles detaching from the coat can accordingly be decomposed or composted independently in the environment. When using natural fibers as sheath fibers, a completely plastic-free covering can also be created.
  • the yarn can have a biodegradable coating made of a natural and / or a biodegradable synthetic material, for example natural latex or natural rubber or wollastonite or a compostable polymer, in order to additionally protect the yarn or make it less vulnerable.
  • Natural materials are generally understood to mean materials that, in contrast to synthetic materials, come from natural sources, such as plants, animals or minerals.
  • a biodegradable synthetic material is understood to be a synthetic material that can independently decompose in the environment.
  • the biodegradable coating can preferably be applied by coating the yarn produced, for example by immersion in a liquid coating compound or coating solution, or the finished covering, for example by applying and wiping off the coating compound or coating solution on the surface the wrapping.
  • the container Since only natural (shell and core and possibly coating) and / or biodegradable or compostable materials (shell and possibly coating) are used for the wrapping, the container is very environmentally friendly, so that pollution of the environment on respective location can be avoided.
  • a container can be provided that can also meet strict environmental protection requirements. This is important, for example, when the container according to the invention is used in coastal protection, civil engineering or in other areas in which the container can come into contact with water or groundwater. Even with age-related or wear-related damage to the cover, no environmentally damaging materials get into the water or groundwater. But this is also advantageous on land, since the container according to the invention cannot release any environmentally harmful materials when it is used.
  • the container according to the invention can thus in particular contribute to the implementation of the requirements of the directives 2008/56 / EC (Marine Strategy Framework Directive) and 2000/60 / EC (Water Framework Directive), since both in the manufacture of the mineral fibers of the core and in the manufacture of the sheathing the mineral fibers only natural or biodegradable materials are used.
  • the directives 2008/56 / EC Marine Strategy Framework Directive
  • 2000/60 / EC Water Framework Directive
  • the structure of the environmentally friendly yarn from a mineral fiber, which forms the core of the yarn, and at least one biodegradable sheath fiber with which the mineral fiber is at least partially, preferably completely, sheathed, has the advantage that the yarn, despite the brittleness of the mineral Fiber has a high mechanical strength, in particular breaking strength, and the handling of the yarn can be improved.
  • the mineral fiber, which by itself already has a high tensile strength, is thus protected from certain external influences, which in particular lead to excessive bending.
  • sheath or “sheathed” is understood in the context of the invention that the at least one biodegradable sheath fiber forms a sheath that the mineral fiber or the Preferably completely surrounds the core.
  • the sheath fiber and the mineral fiber do not form a flat material connection, so that the sheath rests on the mineral fiber without adhesion.
  • the at least one sheath fiber can be wound on the core in any desired manner in several windings or turns and / or the core is knitted around with several sheath fibers by looping around and / or the core is braided with several sheath fibers by intertwining.
  • other types of textile and non-stick sheathing can also be considered.
  • the biodegradable sheath fiber (s) runs around the outer circumference (circumferential direction) of the mineral fiber in each case, the individual windings, turns, wraps, braids, etc. of the at least one biodegradable sheath fiber lying adjacent to one another in such a way that the mineral fiber is covered and thus protected by the at least one biodegradable sheath fiber, preferably over the entire longitudinal extent.
  • the sheathing according to the invention does not represent a coating as used in the prior art in the form of a liquid coating compound or coating solution, since the at least one biodegradable sheath fiber used for the sheathing does not enter into any adhesion or a flat material bond with the mineral fiber as is the case with a coating by definition.
  • the biodegradable sheath fiber that is used for sheathing is not an informal material, but has and retains a certain predetermined fibrous shape, which leads to the fact that the yarn as a whole is mechanically more stable or more resilient, as will be explained in more detail below.
  • the yarn used according to the invention has in particular a larger diameter of the yarn, so that bending radii of the yarn in curved areas of the coverings, for example in the knot of a mechanically knotted network or in the event of transverse loads from the surroundings or from the filling, inevitably turn out to be larger.
  • preferred bending radii can be set in a targeted manner via the thickness of the biodegradable sheath fiber used for the sheathing. This in turn significantly reduces the bending load acting on the mineral fiber, for example in the case of heavy loads during use with a heavy filling, in particular in the case of a knotted net. This effect can therefore greatly increase the mechanical load-bearing capacity of the container without having to reinforce the actual load carrier itself, ie the mineral fiber, in a complex and costly manner.
  • the container according to the invention offers overall increased tensile strength and increased mechanical stability.
  • Yarns that only have natural fibers or biodegradable plastic fibers as strength carriers cannot provide the required strengths or load-bearing capacities with a comparable thickness.
  • the mineral fiber provides a stable mineral core for the yarn of the sheath, which is sheathed by the biodegradable sheath fiber to achieve an additionally increased mechanical stability or strength and for protection.
  • the yarn can still adapt subsequently, since a slight displacement of the sheath with respect to the core is possible.
  • a yarn with a mineral fiber to be processed without the sheathing according to the invention would inevitably have to be twisted or twisted or stranded, which restricts the longitudinal displacement of the filaments relative to one another.
  • the sheathing makes it possible to dispense with such a twisting of the mineral fibers of the core, which in turn improves the flexibility.
  • the mineral fiber of the core can therefore be sheathed as a simple, parallel strand, so that when bent, not only the core and the sheath, but also the individual filaments can move better against each other.
  • an improvement in the manufacturing process is also achieved. Due to the brittleness of the mineral fiber, it tends to splice when passing through industrial production plants or production machines. The mineral fiber rubs against deflections, eyelets and other guides and suffers partial breaks. With the sheathing according to the invention with the biodegradable sheath fiber, the mineral fiber is protected from such splicing, so that it can be processed largely loss-free and without damage and, in principle, at a higher production speed, since the mineral fiber itself is not in contact with the guide elements occurs. The biodegradable or compostable materials used for the sheathing or the biodegradable sheath fibers do not suffer due to their significantly higher ductility and suppleness such damage. In addition, as already mentioned, the bending of the mineral fiber when it rests on the deflections, eyelets and other guides is limited by the sheathing, so that fewer breaks occur during manufacture.
  • the sheathing according to the invention can ensure that the abrasion of the mineral fibers lying on the inside is reduced to a minimum. Since the mineral fiber is a material that is very susceptible to abrasion and the filling of a container with an uncovered cover with partly sharp-edged stones, as well as the subsequent handling of the filled container can lead to damage to the cover, one with a biodegradable fiber jacket that is less susceptible to abrasion offers jacketed cover significantly increased handling strength.
  • the jacketed envelope of the container completely encloses the filling, preferably a solid filling which is also nature-friendly or environmentally friendly.
  • the casing in the container according to the invention does not have an opening in the closed state through which the filling can get out of the container.
  • the covering can be made, for example, by sewing, knotting, splicing or other joining methods suitable for textiles of a single mineral fiber or a single yarn or by sewing, knotting, splicing or joining two different mineral fibers or yarns, or the like. can be achieved. It is preferably provided here that the seams or other connections have at least 80% of the strength of the mineral fiber or the yarn in order not to significantly impair the tensile strength or the general mechanical load-bearing capacity of the container.
  • the container or the envelope can be in the form of a thin mat or sheet, for example.
  • a mattress shape with a thickness of preferably up to 80 cm can also be provided.
  • the container can be used for protection against mechanical effects or erosion and for impermeable linings.
  • the sheath is in the form of a horizontal or vertical tube. This can be done by joining the longitudinal edges of the envelope of the container. The open ends of the tube can preferably be closed by sewing, gluing, knotting, splicing or in any other suitable manner in order to hold the filling in the envelope.
  • the container can be used as a storage container, as a barrier, for depositing stones or rubble or as a dam or dike core.
  • a container that has a wrap with a vertical tubular shape can be used for soil improvement or as a vertical drain.
  • the envelope is generally in the form of a sack. Such sacks can be used for flood protection, for scour protection and repair or for building embankments. It can also be used in the form of gabions or in artificial reefs.
  • a container In the form of a net, stones or boulders can be held inside the envelope so that the container can be used as a filter. The meshes of the net are then selected in such a way that the stones cannot pass through them and can thus be held permanently inside the casing.
  • a container is provided, the properties of which are largely determined by the nature of the filling, whereby a certain filter effect can be achieved as a result.
  • Such a net filled with stones can serve as protection or weighting of an object, for example. for example under water.
  • the filled net-like container can be used for straightening, for example to lay pipes or cables on an originally uneven surface.
  • the filling of the container is preferably matched to the permeability of the envelope.
  • the stability of a container increases the faster the water can drain from it, the permeability of the casing preferably being at least 10 times greater than the permeability of the filling of the container.
