2) configuration of various preparation solution: water, 1/3 absolute ethyl alcohol, 1/4 glacial acetic acid are stirred formation A solution, and the absolute ethyl alcohol of butyl titanate, surplus, 3/4 glacial acetic acid stir and form B solution,
3) drip: under the situation of A solution stirring, mixing speed is 1000 rev/mins～2000 rev/mins, and B solution is slowly poured in the A solution, forms C solution,
4) C solution is stirred again 30 minutes～3 hours, formation has uvioresistant, antibiotic, anlistatig TiO
2The nano-sized hydrosol dressing liquid.
The hydrolysis of reagent, polycondensation reaction temperature are controlled at 0 ℃～30 ℃, and the Nano sol dressing liquid storage temperature of preparing is 0～20 ℃.
In preparation process, the mixing speed of reagent is controlled at 1000 rev/mins～2000 rev/mins.
In preparation process, B solution is slowly poured in the A solution, 1/per second～100/per second.
A kind of method for sorting that utilizes the described textile finishing reagent of claim 1 to fabric, its technical process is as follows:
1) pad, the band liquid measure is 60%～80%,
2) oven dry, bake out temperature is 80 ℃, the time is 3 minutes,
3) bake, baking temperature is 130 ℃～210 ℃,
4) hot water wash, temperature are 60 ℃, time 2-5 minute,
5) oven dry, bake out temperature is 80 ℃, the time is 3 minutes.
The present invention has following good effect:
Prepared anti-static function finishing agent ethanol consumption is less, does not use strong acid such as hydrochloric acid in preparation process, and is less to the mechanical performance influence of fabric.The material TiO that uses
2Be non-toxic material, meet national environmental standard with its textiles of handling.The technology that the present invention adopts is fairly simple, makes minuscule investment, and used material purchases are easy, is fit to large-scale production.The COTTON FABRIC ultraviolet effect of being put in order obviously increases, and the ultraviolet permeability of UVA and UVB section reduces to 14.37% and 0.67% from 22.83% and 14.85% respectively, and the UPF value rises to 56.7 from 6.03, and according to the European standard draft specifies, the UPF level is 50
+, have good uvioresistant effect.COTTON FABRIC bacteriostasis rate after the arrangement is 99%.The dacron of putting in order is that 40% condition lower surface resistance is from 10 in relative humidity
14Drop to 10
11, the whiteness CIE value of the COTTON FABRIC after the arrangement becomes 67.7 by original 66.5, and the whiteness CIE value of dacron becomes 80.8 by original 84.2, and finishing agent is little to the fabric whiteness influence, does not influence the follow-up dyeability of fabric substantially.
