Using (cold) plasma-assisted surface activation is a novel and efficient way for surface preparing of a wide variety of fabrics, textiles and polymeric parts. It is well-known that many of textiles, due to their poor surface energy, might not be able to perfectly sustain painting and other similar finishing treatments on their own surfaces. For resolving such problems, the plasma-assisted surface activation techniques have been developed and today are being extensively used in textile industries. The plasma surface preparation encompasses a wide spectrum of surface modification, from a minor topographic change to major chemical modifications of surface layers of textiles, fibers and polymers. Those surface modifications include generation and/or improve in hydrophilic, anti-electrostatic, capillarity, paint and chemical absorbability, effective surface, active sites, adhesion and other remarkable properties on textiles. The merit of this technique will be more cleared when considering capability of this technique in turning less expensive ordinary materials into valuable functionalized-surface products. Therefore, surface preparations of polymers and fabrics has attracted much attention of many industrialists in the fields of polymers and textiles.
The mechanism of this technique as implied by its name, relies on the formation of cold plasma. By the plasm formation, part of the textile is continuously unwound from its roller tube, exposed to the plasma for a while, and then wound onto another roller tube. Depending on the gas type, plasma density and exposure time, the surface modification can be done in four levels; by the first and lowest level, usually an Argon based-plasma becomes responsible for surface cleaning and pollutant removing via breaking the lipid-based compounds. By the second level, advancing the process by adding active gasses such as SF6, CF4 and O2 causes the textiles' surfaces to become etched. In consequence, this level is responsible for increase in micro-roughness which giving rise to improve in paint and chemical absorbability. By the third level, adding other active gasses such as N2, He, Ar, NH3, N2O, CO2, air and the combination thereof, results in surface chemical change by induction and/or replacement of chemical functional groups such as hydroxyl, carbonyl, carboxyl and amine. These added functional groups can bring new properties to the textiles' surfaces. For example, hydroxyl and carboxyl functional groups can turn a hydrophobic surface into hydrophilic one, or amide and amine groups can give rise to high paint sustainability of the processed surface. Continuing plasma processes at the highest and intense level (fourth level), leads to an extensive chemical composition changes on the outermost layers of textiles through reacting and polymerization of gaseous species with textiles' surficial polymer chains. By then, an integrated surficial layer with completely distinguished features from the textiles' bulk structure has took shape.
Some of the main applications of the plasma surface activation in the textiles industries include;
  • Surface activation: free radicals formation and enhancement of chemical functionalization of surface and surface roughness modification
  • Surface cleaning: elimination of organic compound by plasma sputtering
  • Hydrophobic enhancement for encouraging some oil-based binding formations
  • Hydrophilic enhancement for better wettability and tonality
  • Improved waterproof and oil-proof properties of textiles
  • De-starched process facilitation
  • Surface pile yarns removal
The PlasmaTex machine, provided by Adeeco, is built to meet all the main requirements in textiles' plasma surface activation. The roll to roll equipment and its integral design make it a premium choice to be readily employed as an integrated part of most textile companies' product line. The full specifications of the PlasmaTex machine have been listed in the Table.

The plasma surface modification in textiles, fibers and polymers involve a wide spectrum of surficial corrections usages, from a minor topographic change to major chemical modifications of the surficial layers of textiles. In each level of usage, number of nanotechnology-related cases could be mentioned. In one case, the related application lies on the generation and/or increase in nanoscale surface roughness, which is supposed to be effective in improvement of wettability and tonality. In another case, the activated surficial layer leads to improve in adhesion of coating and Nano-layer by providing atomic-level bonding on the textiles' surfaces.
  • Use the proper power cable with UPS
  • Frequently check the integrity of electrical connectivity in high V cable
  • Use of some plasma active gasses accounts for part of corrosion phenomena inside the system. For laboratory, the extent of corrosion is generally negligible, however, frequent use of such gases especially in industrial scale does limit the life equipments.
  • In case of using oxygen as working gas, vacuum pumps have to be prepared under extreme precaution. This is simply because the mixture of oxygen and oil mist present in the pump casing might be very explosive. As one simple precaution measure, avoid using mineral oil.
  • Provide facility that safely takes away all emitted gases from the laboratory.
  • Install the unit in the proper position so as to sufficient air circulation is allowed in all around the unit.
  • This unit must be electrically connected to ground. Connect it only to a properly grounded outlet.
  • Do not using the unit in case of damaged or not working properly, otherwise electrical shock, fire or other hazard may result.
  • Strictly avoid using incompatible gases (such as hydrogen and oxygen mixtures) as working gasses.
  • Do not use abrasive cleaners, cleaning pads or steel wool, as they can scratch or dull the unit door.
