| Popis: | This paper we present several innovative aspects regarding the UHF (ultra high frequency) microwaves used in textile functionalization for obtain a dielectric surface. The UHF microwaves (MW) are in the range 300 MHz÷3 GHz. In general, the microwaves are in the range between 300 MHz and 300 GHz, but for our experiment was used the microwaves at the 2.45 GHz frequency. The microwaves are generated by a magnetron device and used for textile functionalization in order to accelerate the polymerization reaction.This work is a survey regarding the microwave applications for textile functionalization for setting the textile functionalization process by microwaves. The innovative technologies, such as plasma or microwave, have been used frequently in physics area research and in electronics. Both plasma and microwave devices operating in the field of radio waves, LF, UHF [1] and in general, the radio waves are used for TV signals transmission, for satellite communications and mobile telephony. The microwave radiation is is produced by magnetron microwave generator in microwave cavity (vacuum tube). However, for our experiment was used the microwaves at 2.45 GHz. Microwaves (MM) system are based on the absorption of a relatively strong radiation of this frequency in materials (plastics, textiles). The microwaves propagation on the textile materials depends on the dieletric material property. |
