Název v původním jazyce
Nanofibers layer deposited on the hydrophobic fiberglass mesh and polypropylene non-woven textile for air filters production with the enhanced properties due to potential implementation of plasma technology to the manufacturing process
Popis výsledku v původním jazyce
The aim of this functional sample was to perform a set of plasma treatment tests on fiberglass mesh and polypropylene spunbond (PP SB) 30 gsm non-woven textile in order to enhance their properties for future use as air filters. As a plasma source a Diffuse Coplanar Surface Barrier Discharge (DCSBD) was used. Two configurations (planar and curved) of electrodes were used while using ambient air as a working environment. An output of the functional sample is the enhanced adhesion characteristics of carrier substrates after plasma treatment.

Technické parametry
The processing of the carrier fabric and nanofibers was performed using one planar and one curved DCSBD electrode. Plasma was generated in the form of a surface dielectric barrier discharge in air at atmospheric pressure at a supplied H V with a frequency of 15-20 kHz and a peak-to-peak voltage of 20 kV. The tested power of the DCSBD was in the range 400 - 600 W, but it was concluded that the best choice was 400 W. Applying 400 W no damage to the carrier was done and the best results were achieved.
Ekonomické parametry
Nanofibers are not self-supporting and need to be applied to carrier materials, usually textiles. Due to the principle of the spinning production process (electrospinning method), physical or chemical cohesion (adhesion) between the carrier fabric and the nanofibers is not guaranteed in any way. This often leads to their peeling from the carrier fabric and deterioration of the nanofiber membrane. To suppress this phenomenon, it is necessary to either change the surface properties of the carrier fabric or to laminate the fibers with an additional protective layer of fabric. This leads to an increase in the cost of the production process (a chemical treatment step of the carrier fabric or a lamination process must be applied) and a slight reduction in the permeability of the nanofiber membrane. The application of plasma generated at atmospheric pressure can alleviate or completely eliminate some of these shortcomings.
