Description
Technical field
The present invention relates to the preparation field of Uvr Protective Fabric, more particularly to a kind of preparation method of Uvr Protective Fabric.
Background technology
With the continuous improvement of living standard, people are to the multi-functional textile such as health, antiultraviolet, automatically cleaning
Demand it is increasing.Therefore many researchers employ different approach and fabric are modified, are arranged, to meet variation
Functional requirement.For example, because in recent years, the unscientific activity of the mankind causes the destruction of atmospheric ozone layer, makes to be radiated ground
The ultraviolet in face gradually increases, and causes a series of dermopathic generations, and anti-ultraviolet finishing is carried out to textile, can be effective
Human body is protected from excessive ultraviolet radiation.
Uvr Protective Fabric can help human body to resist ultraviolet, and effectively human body is protected.In recent years, antiultraviolet
The production ways of fabric mainly have two kinds：One is to be made anti-purple by adding ultraviolet light screener in polymerization or spinning process
Outer fiber, then again by treatment such as spinning, weavings, so as to produce the fabric of antiultraviolet.Although this kind of method is to producing
The influence of moral character matter is smaller, but this method applicable surface is smaller, is only applicable to the anti-ultraviolet radiation treatment of synthetic fibers.Two is logical
Cross with ultraviolet light screener to pad fabric or coating, fabric is reached the effect of protection.This method is simply easy
Implement, but effect on driving birds is not good, and the treated textile properties change of this method is very greatly.
Although there is two kinds of antiultraviolet processing methods to fabric at this stage, antiultraviolet fiber is only applicable to synthetic fibers
UV treatment, applicable surface is smaller.In addition, fabric is padded ultraviolet light screener or coating result is not good, and this
The treated textile properties change of the method for kind is very greatly.
The content of the invention
Based on the problems of prior art, it is an object of the invention to provide a kind of preparation side of Uvr Protective Fabric
Method, obtained fabric, anti-uv-ray is strong, it may have very strong automatical cleaning ability, and the change of properties of fabric is small.
The purpose of the present invention is achieved through the following technical solutions：
The embodiment of the present invention provides a kind of preparation method of Uvr Protective Fabric, including：
After fabric is rolled in titanium dioxide nano sol by two leachings two, dried 5 minutes at a temperature of 60 DEG C, Zhi Hou
150~170 DEG C bake 2~5 minutes, bake laggard water-filling and wash, that is, obtain Uvr Protective Fabric.
As seen from the above technical solution provided by the invention, Uvr Protective Fabric provided in an embodiment of the present invention, leads to
Cross and fabric is processed by ad hoc fashion with specific titanium dioxide nano sol, obtained fabric is not only provided with very strong
Anti-uv-ray, and also give the very strong automatical cleaning ability of fabric, can effectively degradable organic pollutant, and knit
The change of properties very little of thing.
Specific embodiment
With reference to particular content of the invention, the technical scheme in the embodiment of the present invention is clearly and completely retouched
State, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made,
Belong to protection scope of the present invention.
The embodiment of the present invention provides a kind of preparation method of Uvr Protective Fabric, including：
By fabric in titanium dioxide (TiO2) rolled by two leachings two in Nano sol after, dried 5 minutes at a temperature of 60 DEG C,
Baked 2~5 minutes at 150~170 DEG C afterwards, bake laggard water-filling and wash, that is, obtain Uvr Protective Fabric.
In the above method, the pick-up that two leachings two are rolled is 70%.
In the above method, using titanium dioxide nano sol obtained in following methods, specifically：By the tetrachloro of 3 weight portions
Change during titanium is dissolved in the cold water of 200 weight portions and form solution；
To the weight portion of hydrogen peroxide 1.8~18 that excessive mass fraction is 30% is added dropwise in the solution, peroxidating is obtained
Titanium compound；
It is 10 to pH value to the ammoniacal liquor that mass fraction is 25% is added dropwise in the titanium peroxide compound, stirs 30 minutes,
Filtration washing, obtains water and titanium peroxide；
The water and titanium peroxide that will be obtained are dissolved in water, carry out hydro-thermal reaction, and hydrothermal temperature is 120 DEG C, hydro-thermal time
It is 4~12h, the product obtained after hydro-thermal reaction as titanium dioxide nano sol.
Present invention TiO as obtained in ad hoc fashion2Nano sol carries out particular procedure to fabric, is not only provided with fabric
Very strong anti-uv-ray, and the very strong automatical cleaning ability of fabric is imparted, organic pollution is effectively degraded, and
The change of properties very little of fabric.
Preparation method of the invention is described in further detail with reference to specific embodiment.
The present embodiment provides a kind of preparation method of Uvr Protective Fabric, comprises the following steps：
Prepare TiO2Nano sol：3g titanium tetrachlorides are dissolved in 200g cold water, solution is formed；Dripped in the solution
Plus hydrogen peroxide 1.8g~18g that the mass fraction of excess is 30%, obtain titanium peroxide compound.It is compound to the titanium peroxide
The ammoniacal liquor that mass fraction is 25% is added dropwise in thing, is 10 to pH value, stir 30min, filtration washing obtains water and titanium peroxide；
The water and titanium peroxide that will be obtained are dissolved in water, carry out hydro-thermal reaction, and hydrothermal temperature is 120 DEG C, and the hydro-thermal time is 4~12h,
Hydrothermal product is TiO2Nano sol；
The treatment of fabric：(pick-up 70%) → drying (60 DEG C, 5min) → bake (150- is rolled into fabric → bis- leaching two
170 DEG C, 2-5min) → washing after i.e. obtain Uvr Protective Fabric.
Performance test is carried out to Uvr Protective Fabric obtained above：
Ultraviolet protection coefficient (UPF) test of fabric：According to the method that AATCC 183-2004 are tested, with YG (B) 912E
The ultraviolet transmission rate of fabric before and after textile uvioresistant performance tester (Wenzhou Darong Textile Instrument Co., Ltd.) interpretation of records,
And calculate the ultraviolet protection coefficient before and after fabric entirety.
The whiteness test of fabric：With reference to GB/T8424.2-2001, fabric is folded into 4 layers, is surveyed with WSB digital display whiteness instrument
Whiteness before and after examination textile finishing.
The performance test of fabric degradation of organic substances：Fabric is immersed in methylene blue solution, is degraded 24 hours, tested whole
Percent of decolourization of the front and rear fabric of reason to methylene blue solution.
The ultraviolet protection coefficient test data of fabric：
| UPF values | |
| Untreatment fiber cloth | 18 |
| Treated fiber cloth | 126 |
| Untreated cotton | 16 |
| Treated cotton | 128 |
The whiteness test data of fabric：
| Whiteness value | |
| Untreatment fiber cloth | 13.8 |
| Treated fiber cloth | 14.5 |
