Abstract

Disclosed is a functional curtain fabric with an anhydrous coating layer. The functional curtain fabric is manufactured by method comprising step S1, preprocessing a fabric substrate; step S2, placing the preprocessed fabric substrate in step S1 into vacuum chamber of magnetron sputtering machine for coating: sputtering a metal onto the fabric substrate by using magnetron sputtering technology, so as to form a nano-metal film on the fabric substrate; and step S3, performing anti-oxidation treatment on the fabric substrate covered with the nano-metal film. The functional curtain fabric with an anhydrous coating layer can serve as an effective heat shield against exterior sunlight while having good light transmission. In addition, the functional curtain fabric with an anhydrous coating layer has good antimicrobial properties due to use of a metal coating of silver and titanium, and also has a degree of water resistance due to the nano-metal layer of silver and titanium.
