The invention relates to a nano gold-silver
alloy solution having affinity for fibers and a preparing method thereof. The preparing method comprises the steps that silver ions and gold ions are addedinto a deionized
aqueous solution of amino
end group hyperbranched
polymer, stirring heating is carried out, a nano silver solution and a nano gold solution are made, and are mixed according to the proportion, a high-temperature
hydrothermal reaction is carried out, cooling is carried out, and the nano gold-silver
alloy solution of a core-shell structure is made; the nano gold-silver
alloy is torispherical, and the grain size ranges from 2 to 30 nm; the nano gold-silver alloy solution can be completely absorbed on the
fiber surface at the high temperature, in the use process, silver ions are not released, good
biosecurity is achieved, the solution has the strong
molecular recognition and combining capacity for fibers such as cotton, silk,
wool,
calcium alginate
fiber, and
chitin, through normal temperature or high-temperature water bath, the solution can be completely assembled on the
fiber surface, and the problems that the nano material and the fibers are poor in affinity, load efficiency is low, and environment is polluted are solved.
