Metal content of metallized fiber can be determined by density testing and calculating. The weight of plated metal’s percentage of metallized fiber can be derived form measuring the weight of metallized fiber, and using the density formula and the law of conservation of mass with knowing the density of plated metal and the basic fiber. The characterization and measurement of the metal content of the metallized fiber at home and abroad is compared, the principle of the determination method by density testing is analyzed, the principle of the determination method by density testing is analyzed, and the specific operation is discussed while the silver content determination of silver-plated fiber is as an example, which provides a simple and convenient means for the determination of metal content of the metallized fiber..

Design of antibacterial woven fabrics was discussed in view of visual impact and antibacterial activity. Antibacterial yarns can be obtained from blending and combining of silver-coated fibers. Analysis of manufacturing process and cost shows that core-spinning and sirofil spinning are preferable. Core-spun yarns can be used in filling if silver color is not desired. If silver color is desirable, sirofil yarns can be spaced at regular intervals in filling direction.
