Definitions

  • the invention relates to a method for defibering or de-wooding Bast fiber crops, such as flax hemp, kenaf and jute.
  • Renewable raw materials are growing in popularity as they are not only conserve existing resources, but also contribute to Deliver a reduction in CO2 known as greenhouse gases.
  • Some processes for textile fiber production aimed at as long as possible Win fibers. With flax, these can be approx. 500 x 1000 mm Hemp also have a length of 1000 - 2000 mm.
  • Bast fiber plants before the extraction of the fibers often also Called deforestation, roasted. Through such a roasting process, the pectin layer, which fibers and wood connect, break down or at least weakened. The degradation takes place either enzymatically by roasting bacteria or chemical.
  • the following systems are known in particular: river roasts, Pond roasting, basin roasting and dew roasting, the latter being the most imperfect is.
  • Main area of application for this material, which is preferably produced as long fiber is the manufacture of textiles. At Jute stands the production of bags and fabrics for the non-clothing area in the foreground.
  • de-felling / de-cleavage is carried out without prior Roasting process carried out.
  • this will result in a more uneven fiber achieved, which is also rough and less supple.
  • EP-A-0 398 421 describes a process for defibering or de-wooding Bast fiber plants are known, in which breakage and swinging are effective is worked.
  • the object of the invention is a method for fiber removal or de-wooding of bast fiber plants to provide which material for technical Purposes, not necessarily for textile processing, the process itself being more economical, effective and largely automatable to work as the known method of generating Long fibers.
  • the first process step of pre-comminution has proven to be particularly advantageous of the bast fiber straw to the desired fiber or stack length.
  • the straw is sheared off to a uniform length and on the other hand, transformed into a bulk material to improve the further process be able to automate to minimize costs.
  • this pre-crushing is the prerequisite for the further process no wrapping in fast-moving or rotating machines around rotating or stationary machine parts can occur.
  • Any Straw and straw material not shortened in such high-speed rotating machines the bast fiber strands would be around tools, Wind shafts or axles and increase friction to a standstill or the destruction of the machine or possibly through heating lead to fire.
  • machines are provided for the pre-shredding, which ensure a uniform or fairly uniform length of the stem sections can, especially choppers such as rotor, disc or sickle choppers or with harvested crop pressed into bales or round bale granulators, which are also called granulators in the plastics industry. Further Cross cutters, as are common in veneer paper processing.
  • the defibering in the second process step advantageously takes place in one high-speed rotating mill, in which the fiber removal / de-cleaving through Shear, friction, impact and impact occur.
  • This is fast rotating machines like those in the wood and plastics industry are known.
  • chip breakers Use, in the plastics industry, they are used to manufacture Granules and powders used.
  • pharmaceutical industry and in food technology they are predominantly in a modified form used for the production of powders.
  • mills are also ideally suited to the fibers of the pre-shredded Detach material from the wooden components.
  • This will solve the problem high strength, tough, flexible fiber of brittle, inflexible, woody core and
  • the woody parts are depending on the speed of the machine and tooling broken into shells of different sizes. So is also with unroasted material achieves a fineness and suppleness of the fibers, which of those of roasted material when using conventional Defiberization technologies come roughly the same.
  • the fiber material obtained is, however, under the so-called green towers from unroasted straw Use of conventional technologies in delicacy and smoothness far superior.
  • the separated wooden parts have a particle size on it as a raw material for the production of panels and thermal insulation materials, Qualify very well, especially for bulk insulation.
  • the subsequent separation of fibers and shives can be advantageous with the help of sieves and / or classifiers, the fibers also taking place simultaneously classified according to length and fractionated as well as oversize, dust and foreign bodies can be removed. Furthermore, between the first and a silo and dosing device connected upstream of the second process step his. If a roasting process is to be provided, this can be done second process step are immediately upstream.
  • the short fibers can be created with their new geometry, with a preferred length between 2 and 50 mm, longer fibers up to about 100 mm but are also conceivable to venture into new technical fields of application, in which synthetic fibers predominate to this day, so that overall a big comeback of the bast fiber family is to be expected.
  • This Fibers which used to be a major component mainly in the textile and clothing sector Role have now found much larger areas of application such as for example as reinforcing fibers that are incorporated into plastics, as short fibers, which are processed into nonwovens and felts, as short fibers, processed into deep-drawable mats for the production of molded parts are or as short fibers used for the production of thermal insulation materials be used for construction.
