Notice:

Due to the characteristics of silver, exposed to the air for a long time with alkaline substances or sweat, silver fiber will appear different degree of oxidation, surface uneven color, yellow black etc. This is normal phenomenon, almost no influence for the shielding performance of the fabric. 

Silver fiber fabric's washing and maintenance method are not the same as normal.
