Surgical drapes with critical properties: barrier protection, flame resistance and lint and abrasion resistance. Surgical covering materials contribute greatly to the prevention of infections. They mark the boundary between sterile and non-sterile zones and thus form a barrier between the medical staff and the patient on the one hand, and the surgical wound on the other. Thanks to their special properties, operating room covering materials also offer medical staff protection against infectious diseases by shielding them from micro-organisms.
