Definitions
- the present invention relates to a method and a device for producing non-woven geotextile and a geotextile thus produced, especially based on long plant fibers mechanically bonded.
- Biodegradable geotextiles are usually made in three ways:
- the present invention aims to remedy all or part of these disadvantages.
- a nonwoven geotextile comprising:
- stems and fragments of stems being interwoven by mechanical bonds produced by splashing water.
- the present invention relates to a device for producing a non-woven geotextile, which comprises:
- the present invention relates to a method for producing a nonwoven geotextile, which comprises
- a geotextile is created which has mechanical characteristics similar to, or even superior to, those of known geotextiles at a lower cost. Indeed, by eliminating the transformation of plants, upstream of the constitution of the sheet, it reduces the complexity of the implementation. In addition, the labor required is limited and manufacturing can be highly automated.
- said plants comprise hemp.
- the stems, fragments of stems and plant fibers are coated with earth.
- the earth comprises clay.
- the means for disposing plants in a web of plant fibers comprises means for crushing and / or carding plants.
- the means for disposing plants in a layer of plant fibers comprises a means for orienting the fibers in at least two different orientations, under the action of vibration of a support, or by crossing of supply routes.
- the means for disposing plants in plant fiber web comprises a device for incorporating ropes or cables parallel to the longest length of the sheet intended to serve as guides.
- ropes or cables may be of vegetable origin or other, in particular plastic or metallic.
- the means for disposing plants in a sheet of plant fibers comprises a means of uniformizing the thickness of the sheet of plant fibers.
- the device which is the subject of the invention comprises a means of coating the web of plant fibers with soil.
- the means for coating the sheet of plant fibers is adapted to coat the sheet of plant fibers with clay-containing soil.
- the method of the invention comprises a step of coating the web of plant fibers with soil.
- the sheet of vegetable fibers is coated with clay-containing soil.
- FIG. 1 is a developed view of the device that is the subject of the present invention, in a particular embodiment,
- FIG. 2 represents, in the form of a logic diagram, the steps implemented in a particular embodiment of the device that is the subject of the present invention
- FIG. 3 represents, schematically, a sheet of rods, fragments of rods and fibers before splashing water
- FIG. 4 represents, schematically, a sheet of rods, fragments of rods and fibers before splashing water and
- FIG. 5 shows, schematically and in section, a drain made on the basis of a geotextile object of the present invention. Presentation of at least one embodiment
- FIG. 1 shows a device 105 for producing a geotextile 110.
- the device 105 comprises
- a means 170 for coating the sheet 125 optionally, a means 170 for coating the sheet 125.
- Plants are introduced at the inlet 140 of the device 105.
- the means 115 for arranging the plants constitutes a web illustrated in FIG. 3, stems of crushed plants of a diameter greater than five millimeters, fragments of plant stems and raw plant fibers partially attached to said crushed stems.
- the means 115 for disposing plants comprises, in the embodiment illustrated in FIG. 1:
- a means 140 for entering raw plants in the form of large plants, typically rods measuring up to 2.5 m,
- a means 160 for standardizing the thickness of the web 125 of vegetable fibers also called compaction and lapping.
- the plants used include hemp.
- the hemp is combined with stems of other plants to produce a nonwoven geotextile but having a shorter shelf life and faster biodegradability.
- a geotextile is, for example, suitable for seasonal market gardening.
- the means 155 for orienting the fibers in at least two different orientations acts by vibrating a support of the sheet 125 (the orientation means 155 comprises, for example a vibrating corrugated sheet, which distributes the fibers evenly in different directions) or by crossing supply paths.
- the compaction and lapping means 160 consists of crushing rollers.
- the means 115 for plants in a sheet of plant fibers comprises a device for incorporating ropes or cables, parallel to the longest length of the sheet intended to serve as guides, after the means 160.
- guides can be introduced into the thickness of the sheet 125.
- This means 165 operates by spraying water under pressure. Specifically, several ramps of high pressure jets perforate and / or crush parts of the rods by partially defibrating. In addition, fine materials "stick” and / or adsorb the various fine elements.
- the finished geotextile 110 is rolled or in semi-rigid plates.
- the geotextile thus produced can then be treated according to the uses.
- the device 105 is particularly intended for the manufacture of non-woven geotextiles for use in substitution for the products used for "mulch” and, in particular, the replacement of coconut fiber fabrics or jute soaked by non-woven fabrics based on hemp.
- a coating with earth may be provided.
- a coating with earth containing clay in particular made of pure clay, makes it possible to form a waterproof geotextile.
- a geotextile may form a protection against the penetration of water into a building or a drain, such as the drain illustrated in FIG. 5.
- Coating can be done by projection or impregnation or by crushing of rendered soil. furniture.
- FIG. 2 shows that, in a particular embodiment of the process which is the subject of the present invention, during a step 205, plant inputs are introduced in the form of large plants, typically stems. measuring up to 2.5 m.
- the plants are crushed to form a sheet of crushed plant stems with a diameter greater than five millimeters, fragments of plant stems and raw vegetable fibers partially attached to said crushed stems.
- the rods and / or the fibers are oriented in a manner, in different directions.
- the thickness of the sheet of fibers is uniform.
- fibers or ropes are incorporated into the fibers. parallel to the long length of the fiber web.
- mechanical bonds are created between the fibers of the sheet, in the thickness of the sheet, by spraying water under pressure on the plant fibers or, alternatively, with a multi-stitching machine. needles (needling).
- a nonwoven geotextile is created which has mechanical characteristics similar to, or even superior to, those of known geotextiles at a lower cost.
- this geotextile can be coated, in particular with earth, for example based on clay.
- FIG. 3 shows, in a sheet 125, crushed raw stems 305, with a diameter greater than five millimeters, small raw stems and fragments of stems 310
- the vegetable fibers are, for a part of them, attached to the crushed stems.
- FIG. 4 shows, in a nonwoven geotextile 110, crushed raw stems
- the geotextile object of the present invention has a weight of 200 to 5000 g / m 2 , and preferably between 400 and 1000 g / m 2 .
- FIG. 5 shows a 405 nonwoven geotextile coated with clay 410 to form a drain, here covered with stones 415.
- Geotextile 405 provides the structure and the clay
- the stones 415 retain the geotextile and avoid rapid clogging of the drain with leaves, for example.
- the drained water thus flows around the stones on the clay layer 410 coating the geotextile 405.
- a second layer of geotextile that is the subject of the present invention 420 is positioned above the first, to maintain the intermediate elements.
- the upper layer serves to maintain the clay between the two layers.
- the geotextile layer 420 is less coarse than the geotextile layer 405.
