The research deals with the protective properties of sewn interlining fabric (IF) intended for pockets of jackets, trousers and other garments in order to protect the user from the harmful effects of microwave radiation from mobile devices. The IF was produced from polyamide filaments coated with copper. Measurements of the electromagnetic shielding effectiveness of the face and reverse side of the IF were made at frequencies of 0.9, 1.8, 2.1 and 2.4 GHz, which were repeated after the dry cleaning process and also following ironing in 10 cycles. Surface modification of the IF tested was examined by scanning electron microscopy - SEM. The results showed a complete loss of material protective properties after ten dry-cleaning and ironing cycles. Damage to the surface copper layer that allowed the passage of electromagnetic micro waves in the fabric cycles was also confirmed by SEM micrographs.
