1. A method for generating a halogen-stable anti-microbial synthetic fiber, the method comprising:

  • creating a mixture comprising;

    a base polymer comprised at least predominantly of polyester in pellet form;

    an anti-microbial agent in the form of an alloy powder that includes a combination of transition metals;

    a cationic non-halogen pigment that includes halogen bonding sites; and

    titanium dioxide for softening a hue of the non-halogen pigment;

    heating the mixture to a melt temperature; and

    extruding the mixture to form an anti-microbial synthetic fiber;

    wherein the cationic non-halogen pigment is adapted to attract and bond with halogenic molecules at the halogen bonding sites, thereby shielding the anti-microbial agent from degradation arising from interactions with halogenic molecules.
