Patent EA-002461-B1 (EA)
Title: Method and device for obtaining vegetal fibre material and the use thereof
IPC: D01B1/04
Filed: 1999-08-09
Abstract: 1. A method for obtaining a fibre material (21) suitable as a raw material for insulation purposes or for the manufacture of non-wovens, or as filling or padding material, whereby the material to be treated is dried in a treatment chamber (17) by means of an air flow, and is moved in the treatment chamber (17) in such a way that the fibre material (21) is to a large extent released from the other constituents, characterised in that closed seeds of poplars, willows, composites or similar plants including Epilobium types introduced into the treatment chamber (17), dried and moved there in such a way that the fruits open and expose the fibre material contained in the seed pods (19). 2. A method according to Claim 1, characterised in that the air flow conducts the fibre material (21) to at least one separation chamber (13), whereby the air flow in the separation chamber (13) is reduced and the fibre material is then preferably caught in a net (33). 3. A method according to claim 1 or 2, characterised in that the treatment chamber (17) is subjected to movement. 4. A device comprising a container with a treatment chamber, which is formed by a rotating drum (11) with an axis of rotation which is horizontal or is somewhat inclined at an angle to the axis of rotation, and with a drying device, characterised in that, to carry out the method according to at least one of the preceding Claims, the treatment chamber is provided for in the interior of the drum, and the fruits of poplars, willows, composites or similar plants can be introduced into the interior of the rotatable drum, and can be dried and moved there in such a way that the fibre material contained in the fruit pods (19) is largely released from the other constituents of the fruit. 5. A device according to Claim, characterised in that, in the treatment chamber (17), solid bodies, not rigidly connected to the device, can impact against the harvested material due to movement during operation, and thereby support the process of releasing the seed hairs (21) from the seed pods (22). 6. A device according to Claim 17, characterised in that the solid bodies are media located in the container, such as paddles arranged in a rotatable manner, mixing elements, wooden spheres, filling substances with surfaces which are not hard or are specifically soft, elastic solid bodies (e.g. cork, cork granulates), lightweight filling materials with hard surfaces, cereal grains, corn-cob residue/internal elements, acorns, chestnuts, wood chippings, bark chippings, slivers, broken chips, limestone grit (crushed limestone), lightweight minerals, such as swelling clay or tufa or similar filler materials, 7. A device for the performance of the method according to at least one of the preceding Claims, characterised in that at least one container (10) of the device (1) is provided with at least one air inlet (26) and one air outlet (12) and a separation device connected to the air outlet (12). 8. A use of the fibre material acquired from fruits of poplars, willows, composites, or similar plants, including Epilobium types for the manufacture of insulation materials, filling and padding materials, papers and body paddings or coverings and/or non-woven materials. 9. A use of the method according to at least one of Claims 1-3 on fruits of plant types which develop fruit hairs (hairy outgrowths from the wall of the fruit (pericarp)), e.g. types of the family of the Bombacacea, and on cotton plants and similar plants, such as Epilobium types.
