Definitions

  • the present invention relates to a method for fiizar equipment from
  • Felting-prone animal fibers in particular wool, in which the fibers are subjected to a low-temperature plasma treatment.
  • German patent application DE-41-17-332-A1 describes a method for plasma treatment of running textile webs in u. a dried woolen fabrics are exposed to a direct voltage discharge in air at about 80 to 90 Pa
  • German patent application DE-43-39-427-A1 also describes a plasma treatment process for fabric webs, which is, however, supplemented by a subsequent ozone treatment. This process is used to clean and desize the fabric web by conventional liquid pretreatment of textiles Replacing webs Both processes deal with the treatment of already woven or knitted fabrics or other webs. The documents do not deal with the pretreatment of unspun fibers or raw wool
  • Corona discharge is subjected to a non-polymerizable gas and then colored from a leveling agent-free, water liquor
  • the plasma treatment suffices for a certain improvement in the colorability.
  • the felting of wool is usually reduced by finishing the
  • the non-constant moisture content of the fiber is classified as a disadvantage in these processes due to the resulting fluctuating production throughput. For this reason, the wool material is pre-dried in the processes before the plasma treatment, which means additional process engineering and economic costs
  • the invention has for its object to provide wool, in particular in the form of a sliver, felt-free, so that it does not become matted and shrink in machine wash after further processing into finished goods
  • This object is achieved according to the invention by a method for anti-felting of wool material, in particular animal hair, by means of a
  • Low-temperature plasma treatment characterized in that moist wool material with a water content of 4 to 40% by weight, prior to further processing into textile fabrics or webs, at a pressure of 10 * to 10 mbar over a period of 1 to 600 sek, a high-frequency discharge of a frequency of 1 kHz to 3 GHz and a power density of 0.001 to 3 W / cm J, optionally with the addition of non-polymerizing gases
  • Raw wool is used as raw material after the raw wool wash, sliver or wool yarn, preferably raw wool or sliver
  • the wool material is used in the preferred process with a water content of 5 to 30% by weight, preferably 8 to 25% by weight
  • the piasma treatment is carried out at a pressure of 10 "1 to 1 mbar and in particular over a period of 2 to 5 minutes.
  • the plasma treatment in a microwave discharge of 1 to 3 GHz is preferred
  • the plasma treatment takes place in a pulsed high-frequency discharge, the pulse frequency being up to 10 kHz
  • Particularly suitable gases are oxygen, nitrogen, noble gases, in particular argon, or air, or mixtures of these gases
  • Construction and apparatus arrangements of a low-temperature plasma reactor are known per se. It is preferred to use an electrodeless reactor with a coupling for microwaves.
  • the wool material to be treated is preferably placed underneath the coupling unit The distance of the wool material to the decoupling unit is preferably 1-30 cm, in particular 2-10 cm.
  • the actual low-temperature plasma is generated by feeding in electromagnetic radiation in the frequency range from 1 kHz to 3 GHz, preferably microwaves of the frequency from 1-3 GHz (the power density at the decoupling is in particular 0 1 to 15 W / cm ”).
  • the electromagnetic radiation can be supplied continuously or in pulsed form to the recipient, a pulse frequency of up to 10 kHz being used
  • the special mode of action of the plasma treatment according to the invention could be explained as follows.
  • the liquid present in the fiber desorbs as water vapor / gas from the fiber surface.
  • a glow discharge is created in the reactor with the coupling of the electromagnetic radiation. Energy-rich electrons, ions and highly excited neutral molecules or radicals are formed which act on the surface the
  • the water vapor desorbed from the fiber causes particularly reactive particles to be formed in the immediate vicinity of the respective fiber surface, which act on the surface
  • a treatment time of 1 to 600 s is preferably used
  • a further reaction gas can be passed through the reactor as described, so that in this case a gas mixture results from gas / steam added and desorbed from the fiber
  • the advantages of the invention are that the anti-fuzzing effect produced by this method on the wool material is significantly greater than in the case of material which is pre-dried before the plasma treatment.
  • the method is energy-saving, since a predrying of the material as described in FIG State of the art is required, before the piasma treatment can be dispensed with
  • the reduction in the felt effect is further improved by the plasma treatment according to the invention in terms of levelness, bath exhaustion and amount of dye used, which is higher than in the case of pre-dried material.
  • the process thus offers not only ecological but also economic advantages.
  • the invention described here is particularly suitable for the antifelting of wool fibers of any fineness.
  • the properties of the wool material with regard to the tendency to matting and / or colorability can, if necessary, be further enhanced after the piasma treatment by treating the wool material with resins and other felt-free finishing agents or Color auxiliary center
  • Woolen sliver with a 21 ⁇ m fineness is subjected to a low-temperature plasma treatment.
  • the purpose of the treatment is to reduce the wool sliver for felting.
  • the treatment is carried out in two ways:
  • the plasma treatment is carried out under the following conditions, which are the same in both variants:
  • the volume-related power density was 0.022 W / cm 3 .
  • the felt behavior was determined using the IWTO standard rvVTO-20-69. According to the method carried out according to the invention (material with a moisture content of 15% by weight), the tendency to felt is reduced by 63% in relation to the same material without plasma treatment. In the case of the material treated according to the second variant, only a 49% reduction in felt sensitivity over a material without Plasma treatments determined Example 2
  • Woolen crest with a 21 ⁇ m fineness is subjected to a low-temperature plasma treatment.
  • the purpose of the treatment is to reduce the wool sliver for felting.
  • the plasma treatment takes place after different dwell times of the wool in a vacuum before the actual plasma treatment. This reduces the moisture content of the wool material before the actual plasma treatment.
  • the conditions of the plasma treatment are as follows:
  • Variant 1 Low-temperature plasma treatment of ridge: Ignition of the piasma with a water content of 7% by weight Frequency: 2.45 GHz
  • the area-related power density was at the decoupling unit
  • the volume-related power density was 0.022 W / cm 3 .
  • Variant 2 Low-temperature plasma treatment of ridges: ignition of the plasma with a water content of 6% by weight
  • the volume-related power density was 0.022 W / cm J. Pressure: 0.1 mbar
  • the felt behavior is determined as in Example 1.
  • the tendency to felt in relation to the untreated material is reduced by 69%.
  • the Fiiz tendency is reduced by 65% and according to variant 3 only by 56%.
