Abstract
A protective device, in particular an anti-erosion protective device, preferably a geotextile, is at least configured to be planarly spread over a surface, in particular an earth surface, that is to be protected, and which is at least largely implemented of a plurality of synthetic fibers interconnected via force-fit connection and/or substance-to-substance bond and arranged in such a way that they form an essentially three-dimensional structuring, wherein at least a large portion of the synthetic fibers are at least largely biodegradable.

A protective device which is at least configured to be planarly spread over a surface, that is to be protected, and which is at least largely implemented of a plurality of synthetic fibers interconnected via force-fit connection and/or substance-to-substance bond and arranged in such a way that they form an essentially three-dimensional structuring, wherein at least a large portion of the synthetic fibers are at least largely biodegradable, wherein the synthetic fibers are polymer fibers and wherein the synthetic fibers form a three-dimensional random-fiber fabric having hollow spaces between a large portion of the synthetic fibers, wherein the synthetic fiber of the protective device presents a tension strength that is greater than 70 MPa, wherein when the synthetic fiber of the protective device has gone through an at least 500-hour radiation and weathering test in a weathering chamber, in which the synthetic fiber of the protective device has been subjected at least cyclically at least to a UV-light radiation and at least to a weathering by spray water, the synthetic fiber of the protective device presents a remaining tension strength of at least 66% of an initial strength of the synthetic fiber of the protective device in a non-weathered state.
A protective device which is at least configured to be planarly spread over a surface, that is to be protected, and which is at least largely implemented of a plurality of synthetic fibers interconnected via force-fit connection and/or substance-to-substance bond and arranged in such a way that they form an essentially three-dimensional structuring, wherein at least a large portion of the synthetic fibers are at least largely biodegradable, wherein the synthetic fibers are polymer fibers and wherein the synthetic fibers form a three-dimensional random-fiber fabric having hollow spaces between a large portion of the synthetic fibers, wherein the synthetic fiber of the protective device presents a stretchability above 500%, wherein, having gone through an at least 500-hour radiation and weathering test in a weathering chamber, in which the synthetic fiber of the protective device is exposed at least cyclically at least to a UV-light radiation and at least to a weathering by water, the synthetic fiber of the protective device presents in the expansion test a residual stretchability of at least 50% of an initial stretchability of the synthetic fiber of the protective device in a non-weathered state.
A protective device which is at least configured to be planarly spread over a surface, that is to be protected, and which is at least largely implemented of a plurality of synthetic fibers interconnected via force-fit connection and/or substance-to-substance bond and arranged in such a way that they form an essentially three-dimensional structuring, wherein at least a large portion of the synthetic fibers are at least largely biodegradable, wherein the synthetic fibers are polymer fibers and wherein the synthetic fibers form a three-dimensional random-fiber fabric having hollow spaces between a large portion of the synthetic fibers, further comprising a wire netting,
- wherein the wire netting
- is implemented at least of helix-shaped longitudinal elements, which are braided with one another, and/or
- comprises at least one wire which is implemented at least partly of a high-tensile steel.
