Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] The first preferred embodiment:

[0038] A method for making an anti-ultraviolet fabric, comprising the following steps:

[0039] a) TiO 2 Preparation of hydrosols

[0040] At room temperature, mix a certain amount of butyl phthalate (TBOT) and 1 / 2 volume of HAc evenly, and stir magnetically for 10 minutes to obtain solution A; another 1 / 2 volume of HAc and a certain amount of H 2 O mixed evenly to form solution B; under rapid stirring, solution B was added dropwise to solution A at a rate of 1 drop / s, and continued rapid stirring for 3 hours to obtain light yellow transparent TiO 2 Aqueous sol; wherein, the mass fraction of Ti is 2%, n(TBOT):n(HAc)=1:7.2.

[0041] b) SiO 2 Preparation of hydrosols

[0042] At room temperature, add orthoethyl silicate (TEOS) dropwise at a rate of 1 drop / s into a certain amount of glacial acetic acid (HAc) and wat...

Abstract

The invention discloses an anti-ultraviolet fabric and a making method thereof and relates to the field of functional clothing. According to the technical key points, the making method comprises the following steps: a) preparing TiO2 hydrosol; b) preparing SiO2 hydrosol; c) preparing SiO2 / TiO2 complex hydrosol according to a titanium / silicon ratio of 1:1 to 4:1, mixing the SiO2 hydrosol, the TiO2hydrosol and H2O, performing ultrasonic treatment at a room temperature for 10 minutes, and magnetically stirring for an hour so as to obtain uniform and transparent SiO2 / TiO2 complex hydrosol, wherein the mass fraction of the Si and Ti is 0.75%; d) impregnating the fabric and the complex hydrosol; and e) cleaning. The anti-ultraviolet fabric and the making method thereof have the technical effects that the complex hydrosol is prepared under the low-temperature condition by adopting a sol-gel method, the fabric is subjected to antistatic and anti-ultraviolet finishing by a padding method, andwhen the titanium is added into the hydrosol, the UPF (Ultraviolet Protection Factor) has a large jump, so that the fabric has excellent anti-ultraviolet property. Therefore, the fabric has a certainanti-ultraviolet durability.

Description

technical field [0001] The invention relates to the field of functional clothing, in particular to an anti-ultraviolet fabric and a manufacturing method thereof. Background technique [0002] Ultraviolet light is the general term for radiation with a wavelength of 200-400nm in the electromagnetic spectrum, and it should be concentrated in three parts: UVC, UVB and UVA. Appropriate exposure of the human body to ultraviolet radiation is beneficial to health, but when the human skin is exposed to excessive UVB ultraviolet radiation, it will produce erythema, blisters and burns; UVA ultraviolet rays can activate melanin in the skin, causing pigmentation, thereby forming dark spots. spot. Medical research shows that ultraviolet rays can damage the DNA in skin cells, and exceeding its repair capacity can cause skin cancer. [0003] Anti-ultraviolet textiles are mainly used in clothing, sunshade and other products. As a kind of outdoor sports clothing, windbreaker provides good p...
