(250 DEG C or more) calcinings just can get Detitanium-ore-type TiO2, the method is at high cost, and energy consumption is high；After carrying out fabric using collosol and gel
The method of arrangement is also very much, but is typically all to use the hydrosol, i.e., by titanate ester or salt compounds in certain acid or
It is hydrolyzed to form in alkaline medium in colloidal sol final finishing to fabric, colloidal sol must be prepared in advance, not easy to maintain.Also there is document report in water
In bath, by the way that TiO is added dropwise2Presoma, being lauched solution in ultrasonic room temperature hydrothermal condition makes TiO2Load on the textile, and is converted into
Anatase type nano TiO2, so that fabric is had the function of photocatalytic and uvioresistant etc., but time-consuming, TiO2Utilization rate is low.
Summary of the invention
The object of the present invention is to provide a kind of method for sorting for loading anatase-type nanometer titanium dioxide on the textile, systems
Standby textile has the performances such as photocatalytic self-cleaning effect, uvioresistant.
The present invention provides a kind of method for sorting for loading anatase-type nanometer titanium dioxide on the textile, including following work
Skill step and condition.
(1) Pretreatment of textile: by textile by kiering removal impurity and auxiliary agent, then by its abundant drying for standby；Institute
Stating textile is natural fiber or chemical fibre and their blended or at least one of manufactured textiles that interweave.
(2) preparation of working solution: titanate ester presoma and alcoholic solvent are uniformly mixed under fast stirring, as work
Liquid is spare；Presoma is at least one of the phthalates such as butyl titanate, isopropyl titanate.Solvent be dehydrated alcohol, isopropanol,
At least one of the alcohols such as polyethylene glycol.Titanate esters and the volume ratio of anhydrous alcoholic solvent are 0.1~20.It is stirred to react spacious in room temperature
It is carried out in mouth container, mixing time is 0~60min.
(3) dry textile obtained by step 1 is immersed in step 2 gained working solution and is padded；Or by step 2 gained working solution
Uniform spray-stain dry textile surface (single or double) obtained by step 1.Textile immerse working solution time be 1~
120s, pick-up are 30%~100%, and mode of padding includes an immersing and rolling, a leaching two is rolled, second dipping and rolling or more leachings are rolled more.
(4) textile in step 3 is put into water-bath and carries out hydro-thermal or individual composition, then take out the textile water
It washes, it is dry.Water-bath or steam pH are 3~11, and water-bath or steam temperature are 50~130 DEG C, and water-bath or steaming time are 0~5h,
Drying temperature is 60~200 DEG C.
In order to investigate the TiO loaded on textile produced by the present invention2For nano-anatase, manufactured goods are carried out
XRD and sem analysis, acquired results are shown in Fig. 1-2.
In order to investigate the anti-ultraviolet property of textile produced by the present invention, it is ultraviolet to 200-400nm to test textile fabric
The transmitance of line, acquired results are shown in Fig. 3.
In order to investigate the photocatalytic of textile produced by the present invention, using methylene blue staining fabric, its light is then surveyed
According to change rate, that is, methylene blue percent of decolourization of front and back K/S value, to evaluate TiO on fabric2Photocatalysis performance.Photocatalytic process
It is carried out in self-control lamp box, uses ultraviolet light (20W, wavelength 254nm, 308nm) and visible light (23WPhilips cold light respectively
Lamp, colour temperature are 6500K color of sunshine) irradiation 15h.
In order to investigate textile produced by the present invention upper load TiO2The washability of photocatalytic uses resistance to color of soaping
Fastness instrument has carried out experiment of soaping, soaping condition are as follows: 5g/L standard soaping agent, 40 DEG C, 30min, bath raio 1:50.Acquired results
2 are shown in Table, data are shown soaps by 5 times, and the fabric after arrangement still keeps good photocatalysis performance.
Compared with the prior art, the present invention has the following advantages with effect outstanding.
1, method for sorting of the invention can be by TiO2The direct single or double of the alcoholic solution of the titanate esters of presoma is applied to
On textile, it is not necessarily to special pyroprocess, anatase type nano TiO can be made under room temperature hydrothermal condition2Original position is supported on
On textile；And TiO can be made without adhesive and dispersing agent etc.2It can disperse to fix on the textile well, and with
Textile has firm combination.Method for sorting is simple, and process is short, low energy consumption for process, time saving.
2, textile produced by the present invention not only has good photocatalytic under ultraviolet light, but also under visible light
With good photocatalytic.The present invention is by by TiO2Presoma arrangement loads on textile, and in-situ hydrolysis generates TiO2,
