For present antimicrobial silver fiber, always have three types:
1, Nano Silver, its preparation method is as follows:
(1) is each position that the silver particles (nano-Ag particles) of nanoscale technology is distributed in fiber cross section;
(2) be to contain the solution of Nano Silver by spraying or other technologies addings.
2, contain silver zeolite, its preparation method is as follows:
It is as the nano-Ag particles predecessor, and deposition of silver in porous zeolite, will be contained silver zeolite then and joins in the fiber and go.
3, silver plated fiber, its preparation method is: directly silver-plated at fiber surface.
From antibiotic effect aspect, because Nano Silver and contain silver zeolite and all be present in fibrous inside, contact inadequately with the external world effective because of it, therefore antibiotic effect also decreases; And, do not have electric conductivity because the silver granuel in these two kinds of silver-colored fibers does not link to each other mutually; And the surface silver layer of the third silver plated fiber exposes fully, can guarantee and extraneous 100% contact, thereby antibacterial effect is preferable, and has electric conductivity preferably, can effectively prevent generation of static electricity.
