Embodiment 1
[0072] 【Preparation composition ZN(OH) 2 -Ti 3 (PO 4 ) 4 -TiO 2 】
[0073] An aqueous solution (60 g) of titanium sulfate (concentration: 30 wt %) was added to 1 liter of distilled water, and the resulting solutions were mixed. To this mixed solution, an aqueous solution (about 98 g) of phosphoric acid (concentration: 15 wt %) was added dropwise, and a white precipitate was obtained by mixing. Further, 50.3g of zinc sulfate (ZnSO 4 ·7H 2 O), and stirred. An aqueous solution of sodium hydroxide (concentration: 15 wt %) was added dropwise to the obtained opaque aqueous solution, mixed to adjust the pH to 7.0, and a white precipitate mixture containing Zn(H)—Ti(IV) was obtained. In the product containing the precipitate mixture, titanium tetrachloride (37g) was added dropwise and stirred, then an aqueous solution of sodium hydroxide (concentration was 15wt%) was added dropwise, and the pH value was adjusted to 7.0 by mixing to obtain Titanium deposits. The resulting pre...

[0081] 2 / 3 twill weave, fabric weight 133g / m 2 The fabric (thickness: 0.23 mm at a pressure of 23.5 kPa) was prepared from the following materials, using the composite filaments having a sheath-core structure obtained in Example 1 and the continuous fibers made of conventional polyester Textured yarn (167 decitex, 48 filaments, fiber fineness of monofilament: 3.5 decitex, twist: 0T / m) is alternately used as weft yarn, and textured yarn (110 decitex) composed of continuous fibers of conventional polyester is used. , 48 filaments, the fiber fineness of the monofilament is: 2.3 decitex, twist: 100T / m) as the warp. Incidentally, the same conductive filaments having a sheath-core structure as in Example 1 were woven into the fabric at intervals of 1 cm. The fabric has a dust collection efficiency of 82.7% and an air permeability of 9.8 cm / s. Using this fabric, dustproof clothes were produced in the same manner as in Example 1, and similarly to Example 1, a test of wearing comfort...
Embodiment 3
[0083] Copper sulfate crystals (43.9 g) were dissolved in 1 liter of distilled water, and an aqueous solution of titanium sulfate (60 g) (concentration: 30 wt%) was added to the resulting aqueous solution. About 10 g of a 15 wt % phosphoric acid solution was added dropwise to the resulting mixture at room temperature and stirred to obtain a white precipitate. The solution (A solution) that will contain precipitate, and the aqueous solution (B solution) that contains sodium silicate of 471g are put into different beakers and stirred; The preparation method of described B solution comprises: Sodium silicate is diluted with distilled water To a concentration of 30 wt%, 15 wt% aqueous sodium hydroxide solution (30 ml) was added to the resulting diluted solution. Add solution A and solution B dropwise into a container with 500ml of distilled water, and stir, so that the pH value of the mixture is always maintained at about 7.0. The results obtained containing Cu(II)-Ti(IV)-SiO 2 ...
