Production technology and shielding properties of the needle-punched non-vowen fabrics with carbon additives

Abstract

The goal of this work was to develop needlepunched non-vowen fabrics with radio protective properties. The article describes the investigation of the effect of carbon additives on the shielding properties of the needle-punched non-vowen fabrics for creation of materials to protect human organisms from electromagnetic radiation. The samples were prepared using polyester, polypropylene, wool and cellulose-hydrate filaments. The needle-punched non-vowen fabric was made with the textile apparatus AIN-1800 M. The transmission and reflection coefficients of the experimental samples were studied in the range of 0.3…17 GHz using scalar network analyzer. The electromagnetic radiation transmission coefficient provided by the samples varies in the range of 6.0+12.6 dB and the reflection characteristics vary in the range of –2+–29 dB.
