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.
Claims22
A method for producing durably anti-microbial multi-filament yarns, comprising:
- providing a knitted fabric selected from the group consisting of a circular knitted fabric and a flat knitted fabric;
- forming an inorganic anti-microbial material on at least one surface of a knitted fabric by a PVD method;
- and
- performing a deknitting process for deknitting the knitted fabric to an anti-microbial multi-filament yarn.
A durably anti-microbial multi-filament yarn, which is characterized by being formed from fibers having an inorganic anti-microbial material formed thereof, and the inorganic anti-microbial material is formed as ultra-thin crystallites or a film formed continuously and by turns along an axial direction of the anti-microbial multi-filament yarn.
