Definitions

  • the invention relates to surface treatment of materials and various substrates, more particularly such as textiles, and more particularly to treatment of the materials with combined multiple diverse energy sources, typically one of which may be an atmospheric plasma (AP).
  • AP atmospheric plasma
  • Atmospheric Plasma Treatment improves fiber surface properties such as hydrophilicity without affecting the bulk properties of these fibers, and can be used by textile manufacturers and converters to improve the surface properties of natural and synthetic fibers to improve adhesion, wettability, printability, dyeability, as well as to reduce material shrinkage.
  • Atmospheric-pressure plasma is the name given to the special case of a plasma in which the pressure approximately matches that of the surrounding atmosphere.
  • AP plasmas have prominent technical significance because in contrast with low- pressure plasma or high-pressure plasma no cost-intensive reaction vessel is needed to ensure the maintenance of a pressure level differing from atmospheric pressure. Also, in many cases these AP plasmas can be easily incorporated into the production line.
  • Various forms of plasma excitation are possible, including AC (alternating current) excitation, DC (direct current) and low-frequency excitation, excitation by means of radio waves and microwave excitation. Only AP plasmas with AC excitation, however, have attained any noteworthy industrial significance.
  • AP plasmas are generated by AC excitation (corona discharge) and plasma jets.
  • a pulsed electric arc is generated by means of high-voltage discharge (5-15 kV, 10-100 kHz) in the plasma jet.
  • a process gas such as oil- free compressed air flowing past this discharge section, is excited and converted to the plasma state.
  • This plasma then passes through a jet head to arrive on the surface of the material to be treated.
  • the jet head is at earth potential and in this way largely holds back potential-carrying parts of the plasma stream.
  • the jet head determines the geometry of the emergent beam.
  • a plurality of jet heads may be used to interact with a corresponding area of a substrate being treated. For example, sheet materials having treatment widths of several meters can be treated by a row of jets.
  • AP and vacuum plasma methods have been utilized to clean and activate surfaces of materials in preparation for bonding, printing, painting, polymerizing or other functional or decorative coatings.
  • AP processing may be preferred over vacuum plasma for continuous processing of material.
  • Another surface treatment method utilizes microwave energy to polymerize precursor coatings.
  • the invention is generally directed to providing improved techniques for treatment (such as surface treatment and modification) of materials, such as substrates, more particularly such as textiles (including woven or knitted textiles and non-woven fabrics), and broadly involves the combining of various additional energy sources (such as laser irradiation) with high voltage generated plasma(s) (such as atmospheric pressure (AP) plasmas) for performing the treatments, which may alter the core of the material being treated, as well as the surface, and which may use introduced gases or precursor materials in a dry environment. Combinations of various energy sources are disclosed.
  • An embodiment of the invention broadly comprises method and apparatus to treat and produce technical textiles and other materials utilizing at least two combined mutually interacting energy sources such as laser and high voltage generated atmospheric (AP) plasma.
  • Functionality may be achieved through non-aqueous cleaning like etching or ablating, activating by way of radical formation on the surface(s) and simultaneously and selectively increasing or decreasing desired functional properties.
  • Properties such as hydrophobicity, hydrophilicity fire retardency, anti-microbial properties, shrink reduction, fiber scouring, water repelling, low temperature dyeing, increased dye take up and colorfastness, may be enabled or enhanced, increased or decreased, by the process(es) which produces chemical and/or morphological changes, such as radical formation on the surface of the material.
  • Coatings of material, such as nano-scale coatings of advanced materials composition may be applied and processed.
  • Combining (or hybridizing) AP plasma energy with one or more additional (or secondary) energy sources such as a laser, X-ray, electron beam, microwave or other diverse energy sources may create a more effective (and commercially viable) energy milieu for substrate treatment.
  • the secondary energy source(s) may be applied in combination (concert, simultaneously) with and/or in sequence (tandem, selectively) with the AP plasma energy to achieve desired properties.
  • Secondary energy sources may act upon the separately generated plasma plume and produce a more effective, energetic plasma milieu, while also having the ability to act directly on the surface and in some cases, the core of the material subjected to this hybrid treatment.
  • the techniques disclosed herein may be applicable, but not limited to the treatment of textiles (both organic and inorganic), paper, synthetic paper, plastic and other similar materials which are typically in fiat sheet form ("yard goods").
  • the techniques disclosed herein may also be applied to the processing of plastic or metal extrusion, rolling mills, injection molding, spinning, carding, weaving, glass making, substrate etching and cleaning and coating of any material as well as applicability to practically any material processing technique.
  • Rigid materials such as flat sheets of glass (such as for touch screens) may be treated by the techniques disclosed herein.
  • a method for treatment of a substrate comprising:
  • a plasma in a treatment region (124) comprising two spaced-apart electrodes (el/e2; 212/214; 412/414; 452/454);
  • the present invention encompasses an apparatus (100, 400A, 400B, 400C, 400D, 400E, 400F, 400G) for treating materials comprising:
  • one or more lasers (130) directing corresponding one or more beams (132) into the treatment area to interact with at least one of the plasma and the material being treated.
  • the present invention comprehends a use of the apparatus described herein for treating a textile substrate
  • the present invention envisages a textile material obtained by the method described herein.
  • the present invention contemplates a method of creating a plasma for material treatment comprising
  • Some advantages of the present invention may include, without limitation, a method of creating a more energetic and effective plasma to clean and activate surfaces for subsequent processing or finishing.
  • ultra-violet (UV) laser radiation either continuous wave (CW) or pulsed
  • CW continuous wave
  • AP plasma electromagnetically generated AP plasma
  • the resulting hybridized energy may have effects that are greater than the sum of its individual parts.
  • Pulsed laser energy may be used to drive the plasma, creating waves, and the laser energy accelerates the resultant plasma waves which act upon the substrate like waves crashing on the beach.
  • the accelerated and more energetic plasma may initiate radicals in the fiber or surface of the treated substrate and attach ionized groups to the initiated radicals. Attachment of such functional groups as carboxyl, hydroxyl or others attach to the surface increasing polar characteristics may result in greater hydrophilicity and other desirable functional properties.
  • the invention advantageously combines energy sources in a controlled atmospheric environment in the presence of a material substrate.
  • the net result may be conversion and material synthesis in the surface of the substrate - the substrate may be physically changed, in contrast with simply being coated.
  • a high frequency RF plasma is created in an envelope (or cavity, or chamber) formed between rotating and driven rollers which extend across the width of the processing window.
  • the plasma field generated is consistent across the width of a treatment area, and may operate at atmospheric pressure.
  • a high power Ultra Violet UV) laser is provided for interacting with the plasma and/or the material being treated.
  • the beam from the laser may be shaped to have a rectangular cross-section exhibiting a consistent power density over the entire treatment area.
  • a gas delivery system may be used to combine any combination of a plurality (such as 4) of environmental gases and precursors into a single feed which populates the hybrid plasma chamber.
  • a spray or misting delivery system may be provided, capable of applying a thin, consistent layer of sol-gel or process accelerants to the material being treated, either pre- or post- processing.
  • the process of combining plasma and photonics is dry, is carried out at atmospheric pressures and uses safe and inert gases (such as Nitrogen, Oxygen, Argon & Carbon Dioxide).
  • safe and inert gases such as Nitrogen, Oxygen, Argon & Carbon Dioxide.
  • the laser may intensify the effective power of the plasma as well as acting on the substrate material in its own right.
  • the surface of the fibers may be ablated in a controlled manner, thereby increasing the hydrophilicity of the material (such as a textile material). Additionally, be introducing environmental gases into the process zone of the system, chemistries may be created at the surface of the material (e.g., fabric) which may result in chemistries that react with a dyeing media to effect a more efficient dye penetration or a more intense coloring process or reduction of dye temperature. For example, preparing the fibers of the textile to give a better controlled uptake of chrome oxide dyes to improve the intensity of black achieved. There is, therefore, potential for this process to reduce the chemical content of dyes which could reduce both negative environmental impact and processing costs.
  • the process may achieve material synthesis in the surface of the substrate.
  • the system ablates the surface of the substrate and a series of chemical reactions between the substrate and the environmental gases synthesize new materials in the surface of the fibers in the textile web.
