Impact of dry cleaning on the electromagnetic shield characteristics of interlining fabric

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 a user from the harmful effects of the microwave radiation from mobile devices. The IF was produced from polyamide filaments coated with copper. Measurements of electromagnetic shieldings effectiveness regarding IF on the face and reverse side were done at frequencies of 0.9, 1.8, 2.1 and 2.4 GHz. These measurements were repeated after the dry cleaning process and also following the ironing through 10 cycles. Surface modification of tested IF was examined by scanning electron microscopy, SEM. The results showed 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 through the fabric cycles was also confirmed by SEM micrographs.
