Definitions

  • Mat-like structures are e.g. in India and China by manual interlacing of long thin bamboo chips (single chip thickness ⁇ 1 mm) produced by multiple splitting of the straws and subsequent pressing of up to 3 individual chips. They have become known under the acronym BMB (Bamboo at Board).
  • BMB Bitboo at Board
  • the production of the above Mats are very labor-intensive and take place predominantly in manufacturing-like production facilities.
  • the material supply can preferably be carried out in one or more lines working independently of one another, the material composition of the material coming from the individual supply lines being preferably variable and the material supply in individual, in particular the outer layers of the nonwoven material or nonwoven material body produced in this way is combined with a longitudinal orientation of the serpentine, fibrous particles, preferably after the formation of the fleece, taking into account different basis weights and the material composition of individual layers, fixing the particle bearings appears to be obsolete and, depending on the intended use of the fleece material, mechanical strengthening, superimposed thermal and / or pressure treatment, a surface treatment and possibly a packaging is exposed.
  • the bamboo particles are made as thin and flexible as possible, e.g. from flax, hemp and / or thermoplastic materials in mass fractions ⁇ 20% are added in order to achieve an reaching connection of the bamboo particles with each other in the aerodynamic mixing process before the fleece is laid and to maintain and secure them at least until they are fixed.
  • the spraying of water glass solution or latex-like suspensions have proven useful for chemical-physical fleece fixation.
  • the bamboo particles to be provided for the individual fleece layers or layers are mixed intensively with finely divided natural and / or plastic fibers prior to the task on the fleece formation level.
  • different particle dimensions from the range described in Example 1 for particle diameter d part and particle length l part are permissible in each of the preferably 5 layers.
  • the material is fed in several independently working lines.
  • the material feed in individual, in particular the outer layers can be combined with a longitudinal orientation of the slender fibrous particles.
  • the particle layers are fixed, taking into account different grammages and material composition of individual layers and / or layers.
  • the thermomechanical fleece fixation is prepared by additionally spraying with latex-like suspension of fine-particle thermoplastic particles, by mixing in thermoplastic fibers and / or thermoplastic powders to be additionally sprinkled on.
  • the ' 3 non-compressed nonwovens used differ in terms of basis weight (in the range from approx. 800 g / m 2 to approx. 1200 g / m 2 ) and fiber orientation.
  • basis weight in the range from approx. 800 g / m 2 to approx. 1200 g / m 2
  • fiber orientation in the range from approx. 800 g / m 2 to approx. 1200 g / m 2
  • the best results in terms of deflection and bending tensile strength were achieved with the lightweight panels with consistent longitudinal alignment of the bamboo particles.
  • a 40% increase in deflection was achieved, the permissible bending tensile stress increased by up to 15% depending on the type of reactive resin used.
  • the thicker nonwovens caused further significant increases in the permissible deflection; the breaking load under bending tensile stress, however, went back to the area of the fiber-free zero test.
  • reinforcement tabs made of bamboo fiber fleece can be glued to the tension side of concrete, steel and wooden girders.
  • bamboo fiber particles for the production of reinforcing straps can be produced with diameters 0.1 + 0.5 mm ⁇ d part ⁇ 2 +3 mm and lengths l part in the range from 4 + 6 mm to 50 +60 mm. This enables you to react optimally to different mechanical requirements on the fiber raw material side.
  • bamboo fiber fleeces single-layer non-woven material body, multi-layer non-woven material composite body
  • thermomechanically compressed and reshaped bamboo fiber fleeces for spatially resilient components and / or walls.
  • the bamboo nonwoven material is biodegradable, which is the case with the fixing or impregnating treatment of the fiber composite, e.g. bamboo particles / fibers / fiber bundles and finely divided other natural auxiliary fibers (such as hemp) with plastic material can be guaranteed by using biodegradable plastics.

Abstract

La présente invention concerne un non-tissé fibreux, un corps non-tissé, un corps composite non-tissé, un procédé pour produire un non-tissé fibreux et son utilisation, des particules de bambou fibreuses, des fibres de bambou ou des faisceaux de fibres de bambou étant liées de préférence par utilisation d'éléments de liaison auxiliaires tels que des fibres naturelles, pour constituer un non-tissé. La réalisation dudit non-tissé s'effectue par ouverture mécanique et pré-fractionnement de tiges de bambou, production d'un mélange avec un agent auxiliaire adhésif, dépôt sur une surface de production de non-tissé, puis fixation du non-tissé fibreux pour former un corps non-tissé.
