Abstract: An apparatus for producing fibers includes a raw materials supplier, a coagulating agents supplier and at least one spray nozzle. The raw materials supplier is used for supplying raw materials. The coagulating agents supplier is used for supplying coagulating agents. The spray nozzle has an inner needle and an outer needle. The inner needle is connected to the raw materials supplier for spraying the raw materials. The outer needle is connected to the coagulating agents supplier and covers the inner needle for spraying the coagulating agents. The raw materials sprayed by the inner needle interact with the coagulating agents sprayed by the outer needle to form the fibers.

Abstract: A method for producing durably anti-microbial yarns is disclosed. An inorganic anti-microbial material is formed on at least one surface of a knitted fabric by a physical vapor deposition method, and then the knitted fabric is deknitted to anti-microbial yarns. The anti-microbial yarns provide a better wash ability and durably anti-microbial effect, and are suitable to be blended with other yarns to a softer anti-microbial fabric.
