Definitions
- the invention relates to bamboo fibers suitable for the production of nonwovens, to a process for producing such bamboo fibers, and to the use thereof for the production of fluidized nonwovens, which in turn can be used for the production of molded articles and technical composite materials.
- bamboo is now used increasingly in use.
- the exotic grass plant is used for parquet floors, roofs, toys, fittings in cars and furniture (eg Heilhansa exclusive 1/2013, pp. 60-65 ).
- bamboo is a fast growing resource.
- bamboo forests that are harvested and grow back quickly.
- bamboo fibers are also used in textiles, but only in a very small amount because the manufacturing process is too expensive.
- cotton fibers serve as the carrier fiber for the hard bamboo fibers.
- the fabric must no longer carry the designation of bamboo, since only 10% of the fiber is used. From bamboo poles are built in Asia very high scaffolding, which does not rot and therefore very safe (no water absorption).
- bamboo fibers unlike coal, glass, steel or aramid fibers have a large surface area due to their rough structure. This leads to a particularly intimate connection with the plastic matrix.
- bamboo fibers are also a renewable raw material, which is very inexpensive compared to the conventionally used fibers, but also compared to other natural fibers.
- bamboo fibers have an antibacterial effect, making their use in fiber-reinforced plastics for the medical field conceivable.
- a method of bamboo preparation is in US 4,857,145 proposed to be dissolved by the combination of different chemicals with the application of increased pressure pre-shredded bamboo in its fiber components and then as bamboo fiber pulp for further process steps z.
- B. pulp production is available.
- the so-called desizing with water is not a solution, since the necessary long storage in the water a digestion process is created which also attacks and damages the fibers. Thus, a dust-free opening is no longer possible.
- the bamboo fibers described in the abovementioned patent applications are not suitable for the production of nonwovens made of bamboo fibers.
- bamboo fibers are primarily intended for the production of fiber-reinforced molded parts, which are flame retardant and very light.
- the resulting composite materials should be shatter-proof.
- coal and ammnite fibers can be saved, thus reducing energy costs.
- the use of calcium oxide, also quick lime, quick lime, quicklime, lime or quicklime, facilitates the removal of the sugar components, especially lignin, and prevents fouling of the fibers and binder material.
- the white powder reacts with water with a strong evolution of heat, so you can do without preheating when using quicklime. Through the reaction with water while calcium hydroxide ( slaked lime, lime water ) is formed.
- the fibers are released from the line network and can be processed in the conventional method and disassembled into single fibers.
- microwaves having a frequency of 2.45 GHz or 915 MHz and a microwave power of 0.8 kW to 9.6 kW (12 ⁇ 0.8 kW) are used to heat the treated and washed bamboo material.
- the microwave used achieves a very uniform and rapid heating of the entire bamboo material, wherein overheating of the already dry surface can be avoided and the core water is transported by increasing the partial pressure of vapor in the product core quickly and continuously to the surface.
- the fibers obtained in this way can be dried in a manner known per se after wetting and, if appropriate, heating with one or more cascaded fiber openers, e.g. one or more sawtooth drums are opened.
- one or more cascaded fiber openers e.g. one or more sawtooth drums are opened.
- This method makes it possible to produce a very large amount of nonwoven bamboo fibers economically and without environmental impact.
- the method according to the invention makes it possible to defiberize large amounts of bamboo in an environmentally friendly manner.
- the fiber thus obtained naturally has a low water absorption. (no rotting), no odor (emulsions) and tensile strength, such as steel. This is the ideal fiber to arm plastic. Also as a building material it is suitable and much more.
- Another object of the invention is the use of the bamboo fibers according to the invention for producing a fluidized non-woven by mixing with binder fibers.
- nonwovens can be used for producing fiber-reinforced plastics and building materials. They can replace glass or carbon fibers, thermally or thermoset bonded.
- the short fibers resulting from the mechanical fibers can be sewn together again and processed as an endless mat.
- bamboo fibers in hole shapes can be deformed into contours by applying a negative pressure, in particular from vacuum.
- the structured bamboo materials thus obtained are outstandingly suitable for the production of insulation materials and / or filling material for seat cushions.
- Fig. 1 shown lateral view of a preferred embodiment of an apparatus for carrying out the inventive method for continuously producing a crushed, treated with an alkaline agent bamboo material comprises a height-adjustable bamboo magazine (1) for manual or automatic Remove the bamboo rods.
- the system according to the invention may have 1, 2 or more such magazines.
- the bamboo rods stored in the magazine (1) are moistened via the water spray device (2) by means of the lifting device (13) directly above the centered oblique inlet to the crusher rollers (3, 5).
- Each supply of bamboo tubes has an upper rigid crusher roller (3) and a lower sprung crusher roller (5) which adjusts to the dimension of the bamboo rods due to the roller suspension (12) with adjustable spring pressure.
- the bamboo material After passing through the crusher rollers (3,5), the bamboo material is further comminuted by the rotary cross cutter (10). If necessary, the bamboo material can then be rehydrated via the supply line (4) with further water.
- the container (6) is the powdery means for alkalinizing the moistened bamboo material to make the material fissile (preferably uncalcified lime powder) with integrated agitating means for transporting the powder.
- the in Fig. 3 shown fan (17) accelerates the application of the powdered lime to achieve a uniform coating.
- the mobile shredder is on rails (14) to fill several silos (9) lying one behind the other.
- the material is stored in the stack container 1 to 5, preferably 2 or 3 days.
