Patent ID: 8414659

Claim:
A method of fabricating a low-color distortion antibacterial textile, comprising: providing a textile substrate; preparing an antibacterial composition, comprising: silver nano particles; a protective agent, wherein a molar ratio of the silver nano particles to the protective agent is 1:0.995-1, the protective agent comprises at least two or more components selected from a group consisting of MCl, MBr, MI, MS 2 O 3 , and NH 4 OH, and M represents an element of group IA or IIA, wherein the at least two or more components in the protective agent have different binding rate and disassociation rate to the silver nano particles, such that a concentration of free active silver ions released by the silver nano particles in the antibacterial composition is 0.27˜2 ppm, wherein a concentration of the silver nano particles in the antibacterial composition is 30 ppm; and water; and applying the antibacterial composition onto a surface of the textile substrate.
