  • the container according to the present disclosure can contribute, in particular, to fulfilling the requirements of the Guidelines 2008/56/EG (Marine Strategy Framework Directive) and 2000/60/EG (Water Framework Directive) because both in the making of the mineral fibre of the core as well as in the making of the encasement of the mineral fibre only natural or, respectively, biodegradable materials are used.
  • the construction of the environmentally friendly yarn from a mineral fibre that makes up the of the yarn, and at least one biodegradable sheath fibre that is encasing the mineral fibre at least in part, preferably entirely, has the advantage that the yarn despite the brittleness of the mineral fibre retains high mechanical resilience, in particular breaking strength, and the handling of the yarn can be improved.
  • the mineral fibre which exhibits a high tensile strength already on its own, is protected from certain exterior influences which may lead, die in particular to excessive bending.
  • the term “encasement” or, respectively, “encased” shall be understood to mean that the at least one biodegradable sheath fibre creates a sheath which surrounds the mineral fibre or, respectively, the core preferably entirely.
  • the sheath fibre and the mineral fibre do not enter into an extensive substance-to-substance bond so that the sheath lies on the mineral fibre free of adhesion.
  • the at least one sheath fibre may be wound onto the core in any suitable manner in a plurality of windings or coils respectively and/or the core is covered by several sheath fibres by means of mesh-type entwining and/or the core is braided by entanglement by a plurality of sheath fibres.
  • biodegradable sheath fibre(s) run(s) around the external perimeter (peripheral direction) of the mineral fibre, whereby the individual windings, coils, entanglements, braiding, etc. of the at least one biodegradable sheath fibre lie adjacent one another in such a way that the mineral fibre it covered and thereby protected by the at least one biodegradable sheath fibre preferably across its entire longitudinal extension.
  • the encasement according to the present disclosure does not constitute a coating, as used in the state of the are in the form of a liquid coating mass or, respectively, coating solution, because the at least one biodegradable sheath fibre used for encasement does not create any adhesion or, respectively, extensive substance-to-substance bond with the mineral fibre, as is the case, by definition, with a coating.
  • the biodegradable sheath fibre used for the encasement is not a shapeless substance but possesses and retains a certain pre-determined fibre shape, and this is what leads to the yarn being mechanically more stable or durable respectively overall, as will be explained in more detail in the following.
  • the diameter of the yarn is larger so that bending radii of the yarn in bent regions of the encasements, for example, in knots of a mechanically knotted web or in the event of transverse loads emanating from the environment or from the filling will be greater by necessity.
  • preferred bending radii can be purposefully adjusted by means of the thickness of the biodegradable sheath fibre used form the encasement. This, in turn, significantly reduces the bending load acting upon the mineral fibre, for example, under heavy load when used with a heavy filling, in particular, in a knotted web.
  • this effect it is possible to strongly increase the mechanical resilience of the container without the need of reinforcing the actual load bearer itself, i.e. the mineral fibre, which would be complex and costly.
  • the container according to the present disclosure has an increased tensile strength and an increased mechanical stability overall. This is because yarns comprising exclusively natural fibres or biodegradable plastic fibres respectively as stability carriers, provided they are of comparable thickness, are unable to guarantee the needed stabilities or, respectively, load bearing capacities.
  • the mineral fibre by virtue of the mineral fibre a stable mineral core for the yarn of the encasement is provided which is shrouded by the biodegradable sheath fibre for attaining an additionally increased mechanical stability or, respectively, strength and for protection.
  • the yarn may even adapt later due to the adhesion-free connection between the core and the sheath since a slight displacement of the coat in relation to the core is possible.
  • a yarn to be processed without the encasement according to the present disclosure with a mineral fibre would necessarily have to be twisted or, respectively, twined or, respectively, roped leading to a limitation in longitudinal displaceability of the filaments in relation to one another.
  • such a twisting of the mineral fibre of the core can be omitted which in turn improves flexibility.
  • the mineral fibre of the core can be encased as a simple, parallel running string making it easier not only for the core and the encasement but also the individual filaments to be displaced in relation to one another when bent.
  • the abrasion of the innermost mineral fibres is reduced to a minimum. Since the mineral fibre comprises a material very susceptible to abrasion and the filling of a container with a non-encased sheath partially with stones having sharp edges as well as the following handling of the filled container can lead to damage to the sheath, a sheath encased with a biodegradable sheath fibre less susceptible to abrasion provides a significantly increased handling resilience.
  • the encased sheath of the container completely surrounds the filling, preferably a firm filling, which is also nature compatible or, respectively, environmentally compatible.
  • the encasement in the container according to the present disclosure when closed, has no opening through which the filling can exit the container.
  • the encasement can be realised, for example, by sewing, knotting, splicing, or other joining processes suitable for textiles from one individual mineral fibre or, respectively, one individual yarn or by means of sewing, knotting, splicing together or joining two different mineral fibres or, respectively, yarns, or similar.
  • it is provided for the seams or other joints exhibit at least 80% of the strength of the mineral fibre or, respectively, the yarn so as to not significantly compromise the tensile strength or, respectively, the general mechanical resilience of the container.
  • the container or, respectively, the encasement may have the shape, for example, of a thin mat or roll.
  • a mattress shape having a thickness of preferably up to 80 cm may be provided.
  • the container may be used as protection against mechanical influence or erosion and for impermeable linings.
  • it may be provided for the encasement to be in the shape of a horizontal or vertical hose. This can be made by joining the longitudinal edges of the encasement of the container.
  • the open ends of the hose may be closed, preferably, by sewing, gluing, knotting, splicing or any other suitable manner so as to keep the filling inside the encasement.
  • the container may be used as storage container, as a barrier, for depositing stones or rocks or as the core of a dam or, respectively, embankment.
  • a container comprising an encasement in the shape of a vertical hose may be used for soil improvement or as vertical drain. Alternatively, it may be provided for the encasement to be generally in the shape of a bag. Such bags can be used for flood protection, for scour protection and repair or in embankment construction. Also, a use in the form of gabions or in artificial riffs is possible.
  • a container In the shape of a web it is possible to hold stones or pieces of rock inside the encasement so that the container can be used as a filter. In that case the meshes of the web are selected such that the stones cannot pass through them so as to be kept permanently inside the encasement.
  • a container is provided the properties of which are significantly determined by the nature of the filling, whereby a certain filtering effect can be achieved thereby.
  • Such a web filled with stones may serve, for example, as protection or ballast of an object, for example, under water.
  • the filled web-type container may be used for straightening in order to lay, for example, pipelines or cables onto an originally uneven underground.
  • the filling of the container is preferably adapted to the permeability of the encasement.
  • the stability of a container is increased the faster the water can drain from it, whereby the permeability of the encasement is preferably at least 10 times larger than the permeability of the filling of the container.
  • the mineral fibre of the core is a basalt fibre, a glass fibre, a carbon fibre or to comprise mixtures thereof. These are characterised by a high degree of stability or, respectively, tensile strength so that, when these materials are used in the yarn core, a highly resilient container can be provided.
  • the high tensile strength can be achieved, in particular, when the mineral fibre is a continuous filament, i.e. a not first-twisted fibre, or, respectively, a textile filament so that the loads can be distributed over the entire longitudinal extension of the mineral fibre.
  • the sheath as biodegradable sheath fibre to comprise a natural fibre, such as coconut, jute, hemp, cotton or flax, and/or a biodegradable plastic fibre, such as a compostable polymer, or mixtures thereof.
  • a natural fibre such as coconut, jute, hemp, cotton or flax
  • a biodegradable plastic fibre such as a compostable polymer, or mixtures thereof.
  • highly stable natural fibres are used for the encasement.
  • Jute for example, is one of the strongest natural fibres and, moreover, is easy to process so that a simple manufacturing process and a good mechanical resilience can be guaranteed.
  • Cotton likewise, is very hard-wearing and also tear proof in a wet environment and durable. Coconut fibres are able to cling thereby guarantee in an improved stackability while maintaining high positional stability of the containers among each other.

  • synthetic polymers plastics
  • polyester fibres polyester fibres
  • polyacrylics fibres polyacrylics fibres
  • polypropylene fibres whereby synthetic fibres may be used or, for example, a synthetic coating may be used.
  • Due to age and damage to the encasement small particles of the synthetic polymers may become detached in the use of such containers made of plastic materials leading to large amounts to reach rivers and seas when used in hydraulic engineering. Even when the containers used on land, plastic particles may become detached thereby being released into the environment. This leads to undesired environmental pollution.
  • a comparative container geotextiles or, respectively, mineral fibres that contain natural fibres, basalt fibres, glass fibres or mixtures thereof.
  • These mineral fibres are suitably coated, for example, by immersing into a liquid coating material or, respectively, coating solution.
  • This coating prevents abrasion during the use of the container thereby providing protection against wear.
  • the coating itself is manufactured from a natural material so that, even when this suffers abrasion, there will be no environmental pollution by synthetic materials.
  • the encasement is made from a plastic-free and coated yarn.
  • the mineral fibres may be damaged due to the brittleness when fed to or, respectively, when processed in automatic web knitting machines, in particular, when lying on deflections, loops and other guides, which is why the speed of production must be reduced to allow for a continuous process. This leads to an increase in manufacturing time and thereby manufacturing cost.
  • a container in accordance with the present disclosure may be manufactured quickly and affordably while providing high resistance to wear as well as high mechanical stability, in particular, breaking resistance, under load and, at the same time, high environmental compatibility.
