The present research work, using different softeners against water and air permeability resistance. In this three concentration for each of silicone & Fatty acid have been synthesized. Air are discussed by changing the amount softener concentration. It was a great effort to figure out optimal level that would be breathable permeability. results show if is increased, woven fabric decreases, whic...

The spinel oxides Zn0.4Co0.6AlxFe2-xO4 (x=0.0, 0.25, 0.50, 0.75 & 1.0) have been synthesized in the solid state sintering process in air. X-ray diffraction measurements have been carried out in order to check the phase which showed single phase spinel structure for all the samples. Initial permeability, frequency dependence of the complex permeability sintered at different temperatures has been...
