Definitions

  • the invention relates to spunbonded nonwovens or yarns produced from spinning solutions or melts according to the nanovalue splicing spinning process, to which lignin is added before spinning.
  • the spinning solutions preferably in
  • Amine oxides of dissolved cellulose, or the melts, preferably of synthetic fiber-forming polymers are spun from at least one spinning bore and the spun yarn is spliced by means of a Laval nozzle to high speed steadily accelerated gas streams into finer threads and warped with loop and loop formation, the gas flow is substantially laminar in the field of thread formation.
  • the invention further relates to processes for producing such spunbonded nonwovens and yarns from the fibers or filaments.
  • EP 1 379 713 Bl describes a process for the preparation of
  • splicing occurs up to the sudden bursting of the liquid thread monofilament, in that the accompanying accelerated gas flow, whose velocity is higher than the velocity of the monofilament, generates shear stresses on the monofilament.
  • the gas flow is preferably substantially laminar in the area of the thread formation. Due to a special fluidic effect, forces are generated in the liquid thread as a result of the action of the outer gas flow, so that parts of the monofilament splinter off or burst open altogether.
  • the spun threads are cooled by the gas / air flow from the outside or by withdrawal Volatiles outside solid, so that forms a pipe structure. It essentially comes to endless threads in this particular process.
  • Characteristics are always spinnerets spun out of the yarn mass and the accelerated gas flow surrounding the yarn, often in the form of Laval nozzles or in their modification of shaped channels in the flow direction behind the spinnerets.
  • the spinning openings can be larger than in comparison to other spinning methods, and yet fine threads can be produced, which is otherwise possible with linear distortion only with lower throughput. Solid, unmelted or dissolved additives of the thread mass can be added without the risk of clogging in the spinning bores.
  • Lignin as an additive to the dope of fiber-forming polymers, which causes special properties of the threads produced later in yarns or nonwovens.
  • the matrix consists of cellulosic fibers and threads for nonwovens and
  • NMMO N-methylmorpholine-N-oxide
  • the spinning solutions for viscose filaments can also be used.
  • the spunbonded nonwovens or yarns according to the invention are produced by the splicing spinning process (nanoval process), the accompanying air streams depositing the filaments into a nonwoven fabric with the special properties added by lignin compared to the pure spinning composition of the fiber-forming polymers.
  • the threads can also be collected into yarns below the splicing device, each consisting of spinning and gas (Laval) nozzle.
  • lignin is introduced into the spinning dope, ie either into the spinning solution or into the melt prior to spinning, then a binder is present in the nonwoven.
  • the binding of the threads to one another is produced by pressure and temperature effects on the produced nonwoven. It can therefore be omitted that additional binders are later added to the fleece or that binding threads are spun with, spun from separate spinning systems or as bicomponents such as core / sheath threads of special spinning units of two fibers, the sheath of which has a lower softening temperature than the inside of the thread, the matrix, has. chemical see binder or mechanical needling of the nonwoven fabrics are generally no longer required for pure nonwoven weave.
  • the spinning masses are thus loaded with lignin. Similar to wood, the fleece is made by lignin a forces-absorbing dressing.
  • the fiber-forming polymer used according to the invention is preferably cellulose.
  • cellulose as a fiber-forming polymer, it has been possible to show that, instead of the expensive chemical pulp (mainly alpha-cellulose) required for cellulosic viscose / rayon threads, it is also possible to spin paper pulp with high levels of hemicellulose. It has also been shown that paper, for example waste paper, can be added to a cellulose NMMO solution or even make this spinning solution 100% from waste paper and in which highly resistant to contamination splicing can produce nonwovens, again with fine monofilaments larger than in the other methods necessary narrower spin holes. With regard to the embodiment of the method, reference is made to EP 1 358 369 B1.
  • the solvent used for cellulose fibers is preferably NMMO or ionic solvents.
  • An ionic solvent is a salt in which the ions are so poorly coordinated that the solvents are liquids below 100 ° C or even liquid at room temperatures. This requires delocalized charges and at least one ion based on an organic molecule to prevent the formation of a stable crystal lattice. Methylimidazolium and pyrithinium ions have proven to be good
  • spunbonded nonwovens or yarns according to the invention it is particularly preferred if they contain ground wood or wood dust.
  • Polypropylene is preferred in the fiber-forming polymers.
  • additives besides lignin may also be added to the dope.
  • the additives are, in particular, activated carbon, superabsorbents, ion exchange resins, PCM, metals and metal oxides, flame retardants, abrasives, zeolites, phyllosilicates, such as concreteites, or modified phyllosilicates, cosmetics or Mixtures thereof.
  • barium sulfate also lead in powder form can serve.
  • Even liquid lipophilic substances, such as paraffins, waxes or oils, one or more component (s) can be introduced in lower concentrations, for example nanosilver or dyes or else active substances, for example pharmaceuticals Substances or insecticides.
  • the additives are to be added to the spinning solutions and melts, in each case in particle sizes smaller than the opening width of the spinnerets. Further examples can be found in WO 2012/034679 AI.
  • To the solution was added 1.0% lignin in the form of lignosulphonate from the company
  • a lyocell spinning solution was prepared without lignin and spun at 800 mbar air pressure at 2.4 g / min per spinning hole, and there were by splicing the monofilament threads between 1.7 and 3.5 ⁇ , so much finer, which showed in that the lignin produces a higher viscosity of the spinning solution and reduces splicing and longitudinal distortion.
  • the threads were endless (see Table 1, experiment lh). Further experiments with different conditions of throughput
  • a spinning solution could be produced on the basis of otherwise taken pulp for solution-spun threads.
  • wood sanding dust with a particle size of less than 130 ⁇ m of a lyocell
  • the spinning solution can be produced both from chemical pulp and paper pulp, but also "stretched” by paper, also lignin-containing papers, eg K-liners with about 3% lignin, or wood In the case of yarns, this is generally not important, since the binding takes place force-fittingly by twisting all the way to twisting.
  • the spunbonded webs were soft to about 0.5% lignin and harder, stiffer above where high strengths and flexural stiffnesses occurred over 1.5%.
  • the latter products could be used, for example, as the outer skin of automobiles with the advantage of low weight compared to steel and even aluminum.
  • the essentially endless threads act as a reinforcement, ie a reinforcement of the surface structure of these "cellulosic sheets.” Since the lignin-spun spunbonded nonwovens are deposited wet, this can take place in molds and can thus be applied later. NEN of such a band of successive shaped nonwoven bodies, the individual construction elements are made of cellulosic nonwoven. Experiments have also been conducted with polypropylene (PP) and polylactide
  • the fleeces were also characterized by the fact that they could be glued by short thermal treatment of about 30 - 60 seconds using an iron with other nonwovens, cardboard or papers easily.
  • some lignin-containing nonwovens, in particular PP nonwovens were not so thermally sensitive.
  • two strips of once-splice-spun PP and then lignin-containing, spun-spun PP were simultaneously ironed for about 1-2 minutes at a higher but not the highest heat setting of an iron between two boards on an aluminum plate, melting the pure PP and only fusing the lignin-containing one Structure, retained its filaments.
