Problems solved by technology

At present, there are many research reports on the dispersion of inorganic nanoparticles. Usually, nanoparticle surface modification, ball milling and ultrasonic methods are used to disperse them, and then they are formulated into sols or directly dispersed in the matrix. The dispersion method to disperse the dispersion effect is not very ideal, which seriously affects its ultraviolet shielding ability

Embodiment 1

[0029] In situ generation of inorganic nanoparticle TiO in textiles 2 , At room temperature, under the condition of stirring, slowly drop 4.4ml of titanium tetrachloride into the ethanol solution dissolved in 40ml of triethanolamine to form a paste complex. After keeping the complex at about 30°C for a period of time, add deionized water to dissolve and make a saturated solution. Mix the prepared solution with 1-5% amino alcohol aqueous solution and textiles under stirring or ultrasonic dispersion, let the textiles be fully immersed in the solution, adjust the PH1-9 value, and at a certain temperature, by ultrasonic method, The sol of the anatase nano-titanium dioxide is obtained, and at the same time, the nano-anatase titanium dioxide can be obtained in situ in the textile.

Embodiment 2

[0031] In situ generation of inorganic nano-TiO in textiles 2 Particles, at room temperature, under stirring, slowly add 4.4ml of titanium tetrachloride dropwise into ethanol solution in which 40ml of triethanolamine is dissolved to form a paste complex. After keeping the complex at about 30°C for a period of time, add deionized water to dissolve and make a saturated solution. Mix the prepared solution with 1-5% amino alcohol aqueous solution and textiles under stirring or ultrasonic dispersion, let the textiles be fully immersed in the solution, adjust the pH value to 1-9, and add the mixed system to the hydrothermal reaction kettle In the method, the hydrothermal method is adopted, and the reaction temperature is 145° C. to 200° C. to prepare nano-titanium dioxide in the rutile crystal form in the textile in situ.

Embodiment 3

[0033] In situ generation of inorganic nano-SiO in textiles 2 Particles, first mix 8ml of ammonia water with 50ml of ethanol, and mix 8ml of tetraethyl orthosilicate with 50ml of ethanol. Then, under the condition of stirring or ultrasonic dispersion, add the prepared ethanol solution of ammonia water into the ethanol solution of ethyl orthosilicate to obtain a transparent solution, fully immerse the textile in the transparent solution, at 30°C, As the reaction progresses, the transparent solution becomes a sol, and a monodisperse nano-silica sol is prepared, and at the same time, nano-silica can be obtained in situ in the textile fabric fiber.

Abstract

This invention discloses a method for producing inorganic nanometer particle in original position in the textiles. First preparing the transparent solution that can produce inorganic nanometer particle TiO2,SiO2, immersing the textile, then through ultrasonic, hot water and whisking method to use the original position compound technology to produce the inorganic nanometer particle TiO2,SiO2 in the original position in the textile, which improves the dispersed and adhesive force of the nanometer particle in the textile to endow the textile with ultra-violet proof and antibiotic capability.

Description

technical field [0001] The present invention relates to a method for in-situ generation of inorganic nanoparticles in textiles. Background technique [0002] Under the irradiation of ultraviolet rays, people are prone to diseases such as melanoma and skin cancer, and high molecular polymer materials will aggravate aging. In recent years, due to the destruction of the ozone layer, the ultraviolet radiation reaching the ground has increased. Therefore, the protection of ultraviolet rays is very important. The research and development of high-performance UV-resistant functional fabrics not only solve the needs of ultraviolet rays on human beings, but also meet the needs of the textile industry to increase the added value of products. In recent years, many countries are conducting research and development of UV-resistant functional fabrics to reduce the harm to the human body. Protecting the human body from excessive UV radiation has become one of the important goals of develo...
