Definitions

  • the invention relates to a method for finishing textile substrates in low temperature plasma reactors.
  • the invention has therefore set itself the task of finishing organic to create textile substrates at low temperatures, taking the substrate evenly encased by the matrix, not just coated and that regardless of what form the substrate is in, whether it is made of fibers, monofilaments, Fabric braiding, thread rolls or other types of linkage exists.
  • the Equipment should also be independent of whether the substrate is natural or synthetic materials. A prerequisite should also be that there is no chemical conversion of the substrate, but only one Improvement of the function of the substrate for certain areas of use.
  • the object is achieved by the in the characterizing part of claim 1 contained features solved.
  • the procedure described therein enables a space-filling plasma in the reactor, surprisingly has shown that the individual particles in different directions on the Impact the substrate and thus form a matrix around each fiber of the substrate, it does not matter what form the substrate is in. This is what it is about is not a one-sided coating, but actually an all-round coating Sheathing, as amazing as this fact is. It can be natural or synthetic textile fibers or monofilaments or textile materials made up of them his. With the method according to the invention, textiles become new functions grafted on by sheathing each fiber of the substrate.
  • the frequency of the voltage pulses is in the ultrasound range, since then the Turbulence and the kinetic energy of the particles is greatest.
  • the treatment process is carried out so that all pulses of electrical Voltage have the same polarity.
  • the particles of the matrix become so highly kinetic Energy hurled at the substrate that the particles hit the fibers of the substrate sheath and also penetrate into the individual fibrils of the substrate and thus be embedded in the lattice structure of the fibrils, even with one multilayer substrate without chemical changes in the Substrate can be made.
  • Particles with a comparatively low kinetic Energy is stored on the surface of the fibers due to the resistance to penetration from and encase them, whereby the direction of movement of the particles also plays a role can play.
  • the higher-energy particles implant themselves in the fiber or penetrate the fiber or fibers to settle on the neighboring fibers to deposit or also to store in it or to penetrate it, etc.
  • Thermoplastics such as polypropylene and polyethylene treated substrates become.
  • What is new according to the invention is the sheathing of the fibers within the textile surface or within a yarn or a monofilament as well as a multifilament, and the incorporation of the matrix particles into the substrate.
  • Activation i.e. a change the surface tension in a gas plasma, e.g. an oxygen plasma without Target to form a matrix
  • the substrate special function e.g. to convey an improvement in the dyeability.
  • a cleaning process is taking place at the same time, since in the oxygen plasma organic contaminants on the substrate, e.g. Fat in its non-toxic Basic building blocks are disassembled.
  • the textile substrate can be in the form of a fabric, braid, fleece, non-woven or a thread, thread bundle and in the form of fibers of a fiber mass.
  • the matrix is also implanted, but remain anyway - be it again emphasizes - preserve the characteristic properties of the textile substrate, such as. Flexibility, tear and tensile strength or gas and liquid permeability.
  • the look of the textile is not affected either. It deals is not a fabric coating that affects porosity would, but really every fiber, whether short or long, is covered.
  • the Sheathing takes place without noticeable space, because the sheathing layer is in the nano range. No gluing was observed either.
  • the matrix particles penetrate due to the kinetic energy between the molecules of the substrate, so that a heterogeneous mixture is created and the treating textile substrates are wash, boil and cleaning resistant.
  • the pulses superimposed on the base voltage have approximately one evenly steep increase in voltage and an uneven decrease with a peak voltage in the range of KeV, preferably between 2-5 KeV.
  • the frequency of the voltage is in the ultrasound range and is preferably 100-300 MHz.
  • the pressure in the reactor is below 10 mbar, preferably between 1-2 mbar.
  • the process can be carried out in various gas plasmas, e.g. Nitrogen, oxygen, Carbon dioxide or possibly also monomer gases are carried out.
  • gas plasmas e.g. Nitrogen, oxygen, Carbon dioxide or possibly also monomer gases are carried out.
  • Matrix come organic and inorganic materials and their compounds and also synthetic materials in use as a target in the Reactor are inserted. Examples include metals, metal alloys, Metal carbides and oxides, silicates, borates and organic molecules.
  • the substrates can be made from all fibers and continuous fibers (monofilaments) Links exist. It is also possible to mix in the flake Treat spun or mixed threads from both natural and made of synthetic, organic or inorganic fibers, including surfaces as well Threads and flakes as bulk goods can be treated.
  • the functions applied by the substrates can e.g. following demands fulfill.
  • An antistatic can be achieved, the electrical conductivity can be improved shielding against electromagnetic Waves can be obtained, as well as an abrasion resistance, an improved one Sliding behavior, low creasing, a water and stain resistant function. UV protection and IR protection are also possible. All differentiations can not listed here.
  • Turbulence in the plasma reactor generated the matrix particles be removed from the target from all directions with such a high kinetic Impact energy on the substrate that they surprisingly encase are implanted and penetrate the fibers, so that without rewinding e.g. B. spools of thread and rolled-up textile webs can be equipped.
  • bulk material can be encased without circulation of the substrate material and there are crosshairs, overlaps and undercuts no light-shadow effect.
  • the essence of the present invention is that Changes in the technical properties of every fine fibril in every modification of a textile material is made possible. It is the invention around the sheathing and penetration of fibers in porous surfaces. In which The method according to the invention therefore does not seal the textile; so it remains breathable.
  • Fig. 1 illustrates a preferred course of successive Pulses of the same electrical voltage as a function of time.
  • this Drawing is the voltage of the pulses in KeV (kiloelectron volts) on the The ordinate plots the time on the abscissa.
  • the Periods of the pulses about twice as long as the voltage-free periods between two consecutive pulses, i.e. the tension-free periods in about 50% of the time between two successive pulses.
  • FIG. 2 shows a scanning electron micrograph of a carbon fiber, the has been treated with titanium carbide according to the inventive method.
  • the embedded matrix particles are closed as small white spots on the image see.
  • the casing is the white outer ring.
  • Fig. 3 is a recording of several fibers from a thread, the fibers are individually encased by the method according to the invention.
  • An example of the method according to the invention is based on an endless one Described carbon filaments with fiber diameters of 5, the carbon filaments are processed into a fabric and the fabric in a low pressure chamber while maintaining a pressure of 2 mbar in a nitrogen atmosphere or treated in an argon atmosphere using the low-temperature plasma process.
  • Coating was applied to the inside of the wall of the treatment chamber e.g. B. Titanium carbite and polytetrafluoroethylene applied to the formation of Support room plasma from all sides.
  • the pulses of the electrical voltage have a repetition frequency of 150 MHz, the peak voltage of the pulses was 3 KeV.
  • the pulses had the voltage time dependence shown in FIG. 1.
  • the current flow depends on the volume and the conductivity of the substrate. in the In the present case, it was 0.1 to 0.2 watts per liter volume of the substrate.
  • the treatment was carried out for a few minutes.
  • tensile strength and abrasion resistance of the carbon fiber fabrics treated in this way before and after the treatment are listed in the following tables: tensile strenght Fabric without cover Covered fabric Chain 36887 cN 39585 cN Shot 37855 cN 38915 cN Abrasion resistance hole formation at Fabric without cover Covered fabric Chain 3000 tours 6500 tours shot 4000 tours 8000 tours
  • the abrasion resistance was checked on a Martingdale device.
