photocatalyst antibacterial production fabric method and photocatalyst antibacterial fabric

摘要

The present invention relates to a process for producing a photocatalytic antimicrobial fabric comprising (A) a precursor, titanium tetrachloride (TiCl 4₄) Is dropped into distilled water at 4C or lower, and stirred with a magnetic stirrer for 1 to 2 hours to prepare an aqueous solution having a concentration of 0.1 to 2.0 mol / L; (B) To the aqueous solution was added ammonium sulfate ((NH₄)₂SO₄) At a molar ratio of 0.1 to 1.0, and stirring at room temperature for 30 minutes to 1 hour to convert to a quadrangular pyramidal crystal structure; (C) To the aqueous solution is added ammonium fluoride (NH₄F) at a molar ratio of 2.0 to 4.0 and stirring at room temperature for 30 minutes to 1 hour to convert to a porous structure; (D) crystallizing the aqueous solution to convert it to a powder, and adding the powder to the raw polymer; And (E) extruding the polymer to produce an antimicrobial yarn, and weaving the yarn in a predetermined pattern to complete the fabric.Accordingly, the present invention has an effect of improving the overall photocatalytic efficiency by converting titanium tetrachloride into ammonium tetrachloride with a quadrangular pyramid crystal structure and doping ammonium fluoride thereto into a porous structure.
