Go out, 60~85 DEG C of drying, 125~135 DEG C bake 3~10min.
In the above method, solution system described in step (2) be 0.03~0.10mol/L silver nitrate, 0.06~
The mixed solution of the ammonium citrate of 0.20mol/L, the boric acid of 0.3~1.0mol/L.
In the above method, the floride-free water repellent described in step (3) is floride-free long-chain siloxanes, amino modified poly- silica
One kind of alkane, hydroxyl-terminated injecting two methyl siloxane, dimethyl silicone polymer, polycarbodiimide.
In the above method, the solvent in step (3) the floride-free water repellent agent solution is in ethyl alcohol, ethyl acetate, hexamethylene
It is one or more of.
In the above method, the mass fraction of floride-free water repellent is in the floride-free water repellent agent emulsion or solution described in step (3)
3%~10%.
The present invention method do not limited by fabric substrate fiber, to cellulose fibre, terylene, nylon, acrylic fibers, wool,
Fiber crops etc. are naturally and one or more kinds of fiber blends or union of science fabric are suitable for.
Advantage using the present invention is：
1, silver ion both became the basis that fabric obtains super-hydrophobicity as elementary particle construction rough surface in the present invention,
Assign fabric excellent anti-microbial property as antibacterial material again.
2, the basic reaction system that is made of silver ion and ammonium citrate of dipping solution in the present invention, ammonium citrate and
PH adjusting agent ammonium hydroxide is common silver-colored complexing agent, successively sequentially forms three silver medal of citric acid and silver ammonia complex by being added, this makes
Existing in solution of can stablizing of silver ion.The pH stabilizer boric acid solutions additionally incorporated slow down the speed of pH value of solution rising
Degree, to ensure the stability and activity of reaction.
3, the low-surface-energy decorative material that the present invention uses is not fluorine-containing, has environment friendly.
4, as reducing agent but also it not only had been used as adhesive using dopamine in the present invention, nano silver is made preferably to be attached to fabric
Surface improves the durability of super-hydrophobic antibiotic fabric.
5, the dipping process in step (2) of the present invention is only once, easy to operate easily-controllable without repeatedly impregnating repeatedly.
