Definitions

  • the present invention relates to the coating of the surfaces of textile structures, in particular threads, and fibrils in textile articles.
  • the common technique of surface treatment in the field of textile production is that the filaments or filaments are coated prior to further processing or superficially modified by a chemical or physical process. To a limited extent, these methods are also applicable to textile intermediate or end products.
  • the chemical treatment and the coating the usual methods are the application of the coating material or the chemical reagent by brushing, spraying, etc. on the textile material or immersing the textile material in a liquid treatment medium.
  • EP 496 117 A describes a process for producing a sewing yarn provided with an equipment, in particular containing synthetic fibers.
  • an equipment is applied directly after spinning on the sewing thread.
  • the equipment itself or monomers or oligomers are applied to the yarn which are radically / ionically oligomerizable / polymerizable and thereby form the equipment.
  • the radical and / or ion-generating treatment may in this case be formed by a low-temperature plasma treatment.
  • this process is very time consuming and affects the properties of the yarn in the subsequent production of the textile structure.
  • EP 492 649 A 3 describes a process for altering the properties of a textile substrate, wherein an initiator which decomposes into radical and / or ions by physical treatment is applied to the substrate. Simultaneously or subsequently, the physical treatment is carried out and brings the resulting radicals with the textile substrate or a substance applied thereto to the reaction.
  • This method has the disadvantage that a chemical initiator is required, which on the one hand requires a greater amount of chemical aids and, on the other hand, is not harmless from the point of view of environmental compatibility.
  • chemical initiators are usually relatively aggressive substances whose disposal is possible only with considerable effort.
  • the invention is based on the surprising finding that the coating processes known from the gas phase for coating solid objects made of plastic or metal can be applied to threads or filaments and fibers in a textile structure, and lead to products having properties which have not hitherto or only with disproportionately high effort were available.
  • the treatment medium is produced in the process by chemical (CVD) (Rompp Chemie Lexikon, 9th edition (1990), volume 2) or physical (PVD) processes (Rompp Chemie Lexikon, 9th edition (1992), volume 5).
  • CVD chemical
  • PVD physical
  • Preliminary tests for modifying the chemical or physical properties of textile materials by a PVD process, the low-temperature plasma process are known (Y. Rogister, J. Knott, L. Ruys, M.
  • each individual thread or fiber is reliably superficially applied in its entirety and that the individual fibers are also coated during the treatment of threads or multifilament yarns.
  • Coatings produced by the method according to the invention adhere substantially more firmly than conventional layers and can be produced as a non-porous covering of the textile material. This makes it possible to use filaments of materials whose mechanical properties, while desirable, are superficially undesirable reactions with the environment. Examples which may be mentioned are moisture-sensitive or allergenic materials.
  • metal layers are applied to obtain an electrical conductivity or to influence the visual impression.
  • Polymerization may be performed directly on the surface of each fibril of the substrate when the treatment is carried out with a gaseous monomer. It is also possible to carry out in preparation of the coating, first with the same method, an intensive cleaning or preparation of the surfaces, such as. As the dry removal of a lubricant, which over the known methods already significantly better adhesion or treatment intensity can be increased again. Depending on the process conditions, continuous or discontinuous layers can be produced.
  • the process according to the invention requires no solvents or other liquid carriers and that no drying operations have to be carried out, as a result of which the energy consumption is substantially reduced. Because of the high quality of the conversion, it is also possible to reduce the total amount of the coating or reaction material, since the treatment from the gas phase ensures an extremely uniform action on the surfaces to be treated.
  • the treatment of sensitive materials with highly reactive substances for chemical modification of the surface which in the known methods usually high temperatures or were not possible at all, can be carried out according to the inventive method, since the thermal load of the object to be treated by adjusting suitable process parameters reduced or can be avoided.
  • the ions of the plasma have about room temperature in a low pressure plasma treatment.
  • the present method is also very suitable for impregnating volume-containing or three-dimensionally shaped textile body such.
  • the impregnation or the layer structure also takes place in the volume and coated in the interior of the construction all fibers.
  • a preferred embodiment of the inventive method is to bring a textile body in a conventional chamber for the PVD coating by the low-temperature plasma method.
  • the textile body In order to achieve a uniform access of the treatment gas, the textile body is held by a support frame or a clamping frame so that the surfaces are as freely accessible.
  • the process parameters according to the planned coating are set, ie vacuum, gas input and temperature.
  • To be evaporated treatment agents are introduced as usual in this process as a solid or as a powder or granules in the treatment chamber.
  • Suitable gases of the treatment atmosphere are noble gases, for example argon, but also nitrogen and oxygen. The selection depends on the properties of the particular substrate to be coated and the coating material.
  • a particularly strong bond between the layer and the substrate occurs when chemical bonds between the substrate and the layer are formed in the course of the deposition, eg. B. by grafting.
  • Very stable layers are obtained when crosslinking the polymerization, in particular resulting in three-dimensionally crosslinked structures.
  • a cleaning process is observed prior to deposition, which can be forced or promoted by appropriate process parameters, creating a thorough cleaning of the surfaces to be treated of the textile body and thus a high quality of the coating is achieved.
  • An advantage of a coating by surface polymerization according to the present invention is that the activated monomer in spite of their excitation, for. As ionization, only slightly elevated temperature and thus polymerization can also be carried out on temperature-sensitive materials such as thermoplastics. It is also possible to use conventional, chemical type non-polymerizable substances, such as. For example, alkanes, as under the action of a glow discharge, such molecules pass under breaking bonds or cleavage of fragments into reactive forms.
  • textile bodies made of polyethylene filaments were coated with PTFE, whereby the high tensile strength of the polyethylene could be combined with the anti-adhesive effect of the PTFE.
  • Carbon fibers can be protected by a suitable coating against the oxygen in the air.
  • the deposited layers can be performed cleaning, washing and even boiling and (steam) sterilization resistant.
  • the textile material can be placed on rollers in the treatment chamber and rolled over in this during the treatment time, or the textile material can be pulled through from air to air through the chamber, to which the chamber must have input and output locks.
  • a textile body can be holistically equipped with new surface-related properties.
  • the surface treatment is carried out intensively and because of the treatment from the gas phase very evenly in already interwoven or meshed material, and the applied layers can be kept very thin because of the high quality, eg. B. thinner than 1% of the fiber diameter or only a few hundred atomic or molecular layers thick, so that a significant volume increase can be avoided by the coating.
  • the following surface properties can be adjusted by choosing the appropriate treatment (s): antibacterial finish, wash and cook resistant; fungicidal properties; wettability; UV-IR absorption; Radiation, in particular IR, UV, light reflection; lubricity; Wrinkle properties; flammability; Anti Pilling; electric conductivity; etc.
  • the layers adhere very well to the surfaces of the textile material and are well formed even in the finest interstices.
  • a pervasive treatment of voluminous textile structures is also possible, such as spacer fabrics, knitted fabrics, nonwovens and felts.
  • the fiber sheath provided by the invention can be implemented as a process step in existing equipment and coating processes.
  • the invention applies a technology in the textile sector which hitherto has been used only in other technical fields, e.g. has been used in surface hardening metalworking and in PCBs for CFC-free, reliable cleaning even in the finest boreholes.
  • This technology is made available for area and spatial textiles.
  • the molecules of the monomer are excited and fragmented to a considerable extent by collision with the energetic particles, the electrons present in the gas discharge, i. smashed into pieces of molecule. This allows the monomers and fragments in the gas space to react with each other on all surfaces. These reactions are the very basis of plasma polymerization.
  • the plasma that stimulates these processes is an ionized gas consisting of ions, electrons, light quanta, atoms, and molecules. Due to the possibility of low-temperature coating, it is possible to coat in a vacuum at room temperature. This may even coat thermoplastics (e.g., polyethylene or polypropylene). The resulting layers are highly cross-linked three-dimensionally and have excellent adhesion to the substrate.
  • Both processes, the removal and application can be done by the appropriate control of the parameters in one operation, i. occur at a reactor charge. This can ensure that a coating matrix is applied only to an absolutely clean substrate.
  • Another aspect of the up-and-down plasma technology is the hundred percent sterilizing effect of the plasma (destructive effect on organisms). Also by the packaging of e.g. Dressing material can reliably kill off all bacteria.
  • the coating process of plasma technology is a very economical and environmentally friendly technology.
  • the electrical energy consumption is very low.
  • the layers which can be applied plasma-assisted, have completely new properties due to the high degree of crosslinking, which differ fundamentally from those of a polymer prepared conventionally from monomers.
  • the polymer is always a thermoset, is very temperature resistant and even in a small layer thickness free from pinholds (smallest uncovered areas) and is almost vulnerable to any solvent.
  • the high-energy particles excited in the plasma therefore trigger intense and profound effects on the monomer (gas).
  • the cold plasma provides high energies in chemically very effective form at room temperature. Similar reactions are e.g. not realizable in the hot flame. Virtually all organic compounds can be made to coat.
  • each fibril of a thread is encased in the special plasma within the textile surface.
  • the discharge thus also reaches very complicated shaped parts, undercuts and also detects the unexposed contact areas of the fibers.
  • the volume properties of the coated textile are not affected or visibly affected.
  • the textile is in a vacuum vessel during treatment.
  • the resulting excess or waste gases are sucked off by a vacuum pump and can be easily collected or recycled as a cycle back to the reaction.
  • a vacuum pump In principle, in the plasma process an uncontrolled distribution of substances of concern is not to be expected.
  • the reactor for coating the textile substrate can either be formed as a bell reactor, in which the monomer is supplied from above.
  • the substrate is in the vicinity of the cathode or in the cathode drop region, because there the degree of ionization of the coating monomer is high.
  • the flow form results in a radial overflow of the substrate.
  • the plasma polymerization can be divided into five steps, which are partially parallel.
  • the initiation monomers in the gas phase are activated or radicalized by electron impact.
  • monomers adsorbed on the substrate surface are excited by electron, ion or photon bombardment to react with other monomers.
  • a second step, adsorption describes the adsorption of monomers and radical species on the substrate surface.
  • Chain growth is described in a third step. This reaction can occur between radicals and monomers in the gas phase, adsorbed radicals and gaseous monomers, as well as adsorbed radicals and adsorbed monomers.
  • the fourth step, the termination, leads to the formation of polymeric entities.
  • polymers By reacting longer chain radicals in the gas phase, polymers can be formed in the gas phase.
  • the reaction of radicals from the gas phase with adsorbed radicals or adsorbed radicals with one another produces polymers that are adsorbed on the substrate.
  • a fifth step, the re-initiation describes, on the one hand, the repeated fragmentation of the already formed polymer in the gas phase by the action of the plasma and, on the other hand, the process of three-dimensional crosslinking of the polymer on the substrate surface by the action of ions, electrons and photons.
  • the plasma polymerization is carried out in a pressure range between 0.01 mbar and 10 mbar. At low pressures, the achievable deposition rates are too low, while at higher pressures no transparent continuous layers can be produced with the desired properties.
  • Each coating monomer has its own polymerization kinetics because of its chemical composition and structure as well as the required process parameters.
  • the rate of polymerization and thus the rate of growth of layers of different monomers differ significantly.
  • the coating rates are generally higher, since larger low molecular weight fragmentation products can form and attach.
  • several monomers can be applied to the textile substrate simultaneously or in succession by plasma technology.

Abstract

On peut enduire des objets textiles par dépôt en phase gazeuse par procédé physique ou chimique. Les couches déposées sur les fibres ou filaments sont de haute qualité. On peut ainsi enrober les filaments ou les fibres, sans laisser des pores, avec des couches très minces, lesquelles entraînent toutefois une augmentation imperceptible du volume total de l'objet textile. Compte tenu de la haute mobilité des particules du matériau d'enrobage, même des points critiques tels que les points d'enchaînement dans des tissus maillés ou tissés, sont enduits de manière fiable. Cela vaut également pour des corps textiles façonnés tridimensionnels, de formes complexes. Après l'enduction par simple dépôt, on peut également effectuer des polymérisations de la surface, de manière à créer des couches impénétrables sur le matériau textile qui, soit le protège contre l'environnement (allergie, sensibilité à l'air, sensibilité à la lumière) soit lui confèrent des propriétés nouvelles (conductivité électrique, revêtement anti-adhésif). L'enrobage par dépôt en phase gazeuse empêche également, dans de nombreux cas, l'objet textile à traiter de se dessécher.
