The present invention relates to a fabric and, more particularly, to a composite fiber antibacterial fabric with fiber copper alloy wires.
A conventional antibacterial cloth structure comprises multiple artificial fiber yarns, and a chemical antibacterial agent applied on the artificial fiber yarns. However, the antibacterial function is reduced gradually after frequent cleaning of the cloth structure, thereby decreasing the antibacterial effect of the cloth structure. Another conventional antibacterial cloth structure comprises a silver-contained antibacterial fiber fabric. However, the silver ions permeate through the skin into the human body, so that the heavy metal is accumulated in the human body, thereby causing danger to the user during a long-term utilization. Thus, a copper-contained antibacterial fiber fabric is used to replace the silver-contained antibacterial fiber fabric. The copper-contained antibacterial fiber fabric includes a copper ion fiber that has a great antibacterial feature to refrain the growth of bacteria and to reduce smells or stinks. In addition, the copper ion fiber has a hydrophilic feature to perform neutralization with ammonia, isovaleric acid and acetic acid, to eliminate odors. However, the surface of the copper ion fiber contains a copper compound (or metal salt) that is dissolvable and has a poor acid resistance, so that the copper ions are released and infiltrate through the skin into the human body, and then are metabolized and drained outward from the human body. In addition, the antibacterial function of the copper-contained antibacterial fiber fabric is reduced gradually after frequent cleaning, thereby decreasing the antibacterial effect.
In accordance with the present invention, there is provided an antibacterial fabric comprising an antibacterial fabric body including multiple composite lines arranged longitudinally and multiple elastic fiber lines arranged latitudinally. The composite lines and the elastic fiber lines interweave longitudinally and latitudinally to form the antibacterial fabric body. The composite lines and the elastic fiber lines construct a weaving structure with stretching ductility and with determined elasticity and twist. Each of the composite lines includes multiple multi-filament polyester fiber yarns and at least one or more than one fiber copper alloy wire blending and intertwining with the multi-filament polyester fiber yarns to form antibacterial yarns. The at least one or more than one fiber copper alloy wire has a filament shape with a determined flexibility. The at least one or more than one fiber copper alloy wire is oxidized to steadily release copper ions which act in the multi-filament polyester fiber yarns, and each of the composite lines has a linear structure with an antibacterial function by action of the at least one or more than one fiber copper alloy wire.
In accordance with the present invention, there is further provided a method comprising:
a first step (a) including providing a determined amount of copper alloy staple in a melting furnace, adding a determined amount of metallic element in the melting furnace, and melting and kneading the copper alloy staple and the metallic element at a high temperature to form a copper alloy melting liquid, wherein the copper alloy staple contains an electrolytic copper with a high purity, and the metallic element has a high tensile strength, is erosion resistant and is wear resistant;
a second step (b) including filling the copper alloy melting liquid into a casting furnace to directly form a copper alloy embryo material by a casting process;
a third step (c) including stretching the copper alloy embryo material by multiple tensile working processes to form a fiber copper alloy wire, wherein, the fiber copper alloy wire has a filament shape with a determined flexibility after the multiple tensile working processes;
a fourth step (d) including blending and interweaving at least one or more than one fiber copper alloy wire with multiple multi-filament polyester fiber yarns by a determined proportion to form antibacterial yarns;
a fifth step (e) including intertwining the at least one or more than one fiber copper alloy wire in the multi-filament polyester fiber yarns tightly and closely to construct a composite line which contains the at least one or more than one fiber copper alloy wire and the multi-filament polyester fiber yarns, wherein the composite lines has determined elasticity and twist and has an antibacterial function; and
a sixth step (f) including interweaving multiple composite lines and multiple elastic fiber lines longitudinally and latitudinally to construct an antibacterial fabric body having determined elasticity and twist and having an antibacterial function.
