Description
Technical field
It is especially a kind of to prepare photocatalysis from clear using ionic liquid the present invention relates to a kind of preparation method of function fabric
The method of clean wool fabric.
Background technology
Nano-particle is introduced into textile fabric, functional fiber material can be prepared.Nano-particle is drawn at present
It is many to enter the preparation method of wool fiber, such as：Absorption method, sol-gal process, layer assembly method, coating etc..However, absorption method
By mainly making nano-particle be adsorbed onto wool surface by intermolecular Van der Waals force and ionic forces, washing fastness compared with
It is low；The technical process of sol-gal process and layer assembly method is longer, and more difficult control；Coating is to utilize adhesive by nanoparticle
Son is adhered to wool surface, reduces skin-friendly of the wool fiber to human body.
Ionic liquid refers in room temperature or close to liquid, the salt that is made up of completely zwitterion is presented at room temperature,
Referred to as low temperature molten salt.Ionic liquid is the power solvents of rising in recent years.At present, it is usually used in the ionic liquid of protein dissolution
Have：1- butyl -3- methylimidazole acetate BmimAc, chlorination -1- pi-allyl -3- methylimidazoles AmimCl, 1- ethyl -3- methyl
Imidazoles acetate EmimAc, 1- ethyl-3-methylimidazole villaumite EmimCl etc..
The content of the invention
The technical problems to be solved by the invention be the shortcomings that presence for above prior art propose a kind of use from
The method that sub- liquid prepares photocatalytic self-cleaning wool fabric.The technology of preparing is simple and easy, and cost is cheap, to wool fabric
Strength damage is small, does not change wool surface performance, and titanium dioxide nano-particle has good fastness on wool fabric；
Any adhesive is not used in the preparation process, it is nontoxic.
To achieve these goals, the solution taken of the present invention is：One kind prepares photocatalysis certainly using ionic liquid
The method for cleaning wool fabric, it is characterised in that comprise the following steps：
（1）The preparation of lysate：20-50g ionic liquids and 4-10g mercaptoethanols are added in 100ml absolute ethyl alcohols, formed
Mixed solution, 0.1-1.5g titanium dioxide nano-particles are then added in mixed solution, obtain being dispersed with two under sonic oscillation
The lysate of titanium oxide nanoparticles；
（2）By wool fabric in step（1）Repeatedly padded in the lysate of gained；
（3）Wool fabric after padding is removed into ethanol in vacuum desiccator, vacuum is -0.1MPa, temperature 80oC；
（4）The wool fabric for removing ethanol is being heated into 10-30min under 80-150 DEG C of hot blast；
（5）Wool fabric after heating is impregnated in ethanol and solidified, then washes, dry.
The beneficial effects of the present invention are,（1）Limited ionic liquid is set mainly to be distributed using padding method and vacuum drying
In the surface of wool fiber, the Hot-blast Heating of short time can only be partly dissolved to wool surface, without damaging sheep
Inside wool fibre, reduce the damage to wool fiber and fabric；（2）It is partly soluble in wool surface
Wool protein forms protein compression solution, has adhesive attraction to nano-particle；（3）The protein compression that wool surface is formed
Solution solidifies again in ethanol, plays bonding to nano-particle, package action；（4）It is not used in preparation process any viscous
Mixture, it is nontoxic.
