Embodiment 1~4

[0030] Embodiment 1~4 provides the method for textile loaded nano titanium dioxide, described method comprises the following steps:

[0031] Nano-titanium dioxide pretreatment: Weigh 4.5091 g of nano-titanium dioxide particles, respectively add silane crosslinking agent or acrylic acid crosslinking agent whose mass is 30% of the mass of nano-titanium dioxide particles, and 10% of the mass of nano-titanium dioxide particles. Polyether phosphate or acrylic acid-(meth)acrylate copolymer, the specific ratio is shown in Table 1, then added to 500mL ethanol solution with a mass fraction of 20%, adjust the pH to 9, 30kHz ultrasonic treatment for 1h, and dry to obtain the surface Modified treated nano titanium dioxide particles.

[0032] Preparation of nano-titanium dioxide solution: Weigh 1.9822 g of improved nano-titanium dioxide particles, add 0.8% fatty alcohol polyoxyethylene ether of nano-titanium dioxide quality and 0.6% epoxy ethylene ether penetrating agent of nano-titanium d...

Embodiment 5~12

[0040] Embodiment 5~12 has compared the non-woven fabric that cross-linking agent of different proportioning and dispersant consumption obtain, the comparison of rhodamine B decolorization test decolorization rate, described method comprises the following steps:

[0041] Pretreatment of nano-titanium dioxide particles: Weigh 4.9390 g of nano-titanium dioxide particles, add acrylic acid crosslinking agent whose mass is 10%, 30%, and 40% of the mass of nano-titanium dioxide particles, and 10% and 20% of the mass of nano-titanium dioxide particles , 30% alkylphenol polyether phosphate, see Table 2 for specific proportions, then add 20% mass fraction of 500mL ethanol solution, adjust pH to 9, 30kHz ultrasonic treatment for 1h, dry to obtain surface modified modified titanium dioxide nanoparticles.

[0042] Preparation of nano-titanium dioxide solution: Weigh 1.9822 g of improved nano-titanium dioxide particles, add 0.8% fatty alcohol polyoxyethylene ether of nano-titanium dioxide ...

Embodiment 13~17

[0050] The preparation methods of Examples 13-17 are basically the same as those of Example 11, except that, in the pretreatment process of nano-titanium dioxide particles, the pHs used in Examples 13-17 are respectively 10 and 7, and the ultrasonic waves used in Examples 13-17 are The time is 0.5h, 1.5h and 2h respectively, and the nano-titanium dioxide particles subjected to surface modification are obtained by drying. Subsequent steps were the same as in Example 4, and the obtained non-woven fabric was also subjected to the Rhodamine B decolorization test, and the results are shown in Table 3.

[0051] Table 3 is the condition of embodiment 13~17 pretreatment process and the degree of decolorization that finally measures

[0052]

[0053] From the above table in conjunction with the data of Example 4, it can be seen that when the preferred pH is 9, the decolorization rate is the highest, and the condition of the ultrasonic time is further optimized. It can be seen that w...

Abstract

The invention discloses a method for loading nano titanium dioxide on a textile, the textile loaded with the nano titanium dioxide and an application thereof. The method comprises the following stepsof step S1, preparation of a nano titanium dioxide solution: placing nano titanium dioxide particles, an adjuvant and a solvent in a container for mixing, adjusting the pH to be 5 to 10, ultrasonically dispersing for 2 to 5 minutes at 20 to 40kHz to obtain the uniform nano titanium dioxide solution; step S2, a textile loading process: placing the textile in the nano titanium dioxide solution, andperforming the ultrasonic treatment at the temperature of 60 to 95 DEG C for 0.2 to 2h at 20 to 40kHz; and step S3, blocking, fixing and forming: adding a water-dispersible adhesive to fix for 0.5 to1h, and drying and curing at 80 to 120 DEG C. According to the method of the invention, the manufacturing cost is low, the loading fastness of the nano titanium dioxide particles is high, and the problem of agglomeration of the titanium dioxide particles is solved. According to the textile loaded with the nano titanium dioxide prepared by the method provided by the invention, the catalytic actionbetween the nano titanium dioxide particles, air and water molecules is maximized, and the anti-fouling, anti-bacterial and anti-ultraviolet performance of the textile is improved.
