| description | A coated material is a composite structure that consists of at least two components: base material and coating layer. The purpose of coating is to provide special properties to base material, with potential to be applied in EMI shielding and diverse smart technical fields. This paper reports the results of a study about some physical and magnetic properties of coated woven fabrics made from cotton yarns with fineness of 17 metric count. For this aim, a plain woven fabric was coated with a solution hard magnetic polymer based. As hard magnetic powder, barium hexaferrite (BaFe12O19) was selected. The plain woven fabric used as base has been coated with five solutions having different amounts of hard magnetic powder (15% - 45%) in order to obtain five different magnetic woven fabrics. A comparison of physical properties regarding weight (g/m2), thickness (mm), degree of charging (%) and magnetic properties of magnetic woven samples were presented. Saturation magnetizing (emu/g), residual magnetizing (emu/g) and coercive force (kA/m) of pure hard magnetic powder and woven fabrics have been studied as hysteresis characteristics. The magnetic properties of the woven fabrics depend on the mass percentage of magnetic powder from coating solution. Also, the residual magnetism and coercive field of woven fabrics represents only a part of bulk barium hexafferite residual magnetism and coercive field. |
