1. An antibacterial textile comprising:
polyamide polymer fibers, each fiber of a Partially Oriented Yarn (POY) type comprising:
at least 35 milliequivalent per kilogram (Kg) amino end groups;
at least one of: a) Silver metal particles, and b) Silver cation particles; and
the amino end groups and the at least one of: a) the Silver metal particles, and b) the Silver cation particles, dispersed within the polymer of the fiber at a weight content within the range of approximately 10-100 parts per million (ppm);
wherein said each fiber comprises a tenacity within the range of approximately 3.0-4.5 grams per dtex and elongation within the range of approximately 60%-90%; and
the polyamide polymer fibers are blended inside a textile fabric, the polyamide polymer fibers at a weight content within the range of approximately 0.5%-40.0% of the fibers of the textile fabric, such that the content of the Silver metal particles and/or Silver cation particles in the textile fabric is within the range of approximately 0.2-45.0 ppm, whereby the textile fabric is antibacterial in accordance with the American Association of Textile Chemists and Colorists (AATCC) 100-2012 standard.
