Abstract
The invention provides a kind of method that photocatalytic self-cleaning wool fabric is prepared using the NMMO aqueous solution, this method comprises the following steps：（1）NMMO, tricarboxylic ethyl phosphine are dissolved into ethanol/water（Volume ratio is 1:4）In；（2）In step（1）Titanium dioxide nano-particle is added in obtained solution, is stirred vigorously down and obtains the lysate for being dispersed with titanium dioxide nano-particle；（3）By wool fabric in step（2）Repeatedly padded in the lysate of gained；（4）Wool fabric after padding is irradiated under microwave；（5）Wool fabric after irradiation is impregnated in methanol solution and solidified, then washes, dry.This technology of preparing is simple and easy, and cost is cheap, small to the strength damage of wool fabric, does not change wool surface performance, and titanium dioxide nano-particle has good fastness on wool fabric；Any adhesive is not used in this preparation process, it is nontoxic.
Description
Technical field
It is especially a kind of to prepare photocatalysis certainly using the NMMO aqueous solution the present invention relates to a kind of preparation method of function fabric
The method for cleaning 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.
N-methylmorpholine-N- oxides（NMMO）A kind of white crystal, with certain proportion be dissolved in water water white transparency
N-methylmorpholine-N- oxide water solutions, be mainly used in plant cellulose high-performance solvent.After 100oC, NMMO can be with
Thorough solubilising protein macromolecular, obtains the regenerated protein solution of concentration 20% or so.
Tricarboxylic ethyl phosphine（TCEP）It is a kind of very effective thio-alcohol reducing agent, is widely used as protein chemistry and albumen
The Quantitative reduction agent of disulfide bond in the research of matter group.Reagent stability in aqueous and dissolubility are all fine.It is acid,
Stability in alkaline solution is also good.Compared with the thio-alcohol reducing agent such as DTT of other classifications, TCEP is not only a kind of efficient
Disulfide bond reducing agent, and need not be removed in the cross-linking reaction of some sulfydryls.TCEP in very wide pH range all
Selectively can quantitatively it reduce even water-soluble very poor alkyls disulfide.Generally react at room temperature less than 5 minutes
Can is completed.TCEP does not have niff, and is not afraid of oxidation in atmosphere.Thus in protein chemistry and protein group
Learn research usually prioritizing selection TCEP.
The content of the invention
The technical problems to be solved by the invention are the shortcomings that presence for above prior art, propose a kind of use
The method that the NMMO aqueous solution prepares photocatalytic self-cleaning wool fabric.The technology of preparing is simple and easy, and cost is cheap, and wool is knitted
The strength damage of thing is small, does not change wool surface performance, and titanium dioxide nano-particle has good on wool fabric
Fastness；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 using the NMMO aqueous solution
The method of automatically cleaning wool fabric, it is characterised in that comprise the following steps：
（1）（1）5-40gNMMO, 1-3g tricarboxylic ethyl phosphine are dissolved into 100ml ethanol/waters（Volume ratio is 1:4）In；
（2）In step（1）0.1-1.5g titanium dioxide nano-particles are added in obtained solution, is stirred vigorously down and is dispersed with
The lysate of titanium dioxide nano-particle；
（3）By wool fabric in step（2）Repeatedly padded in the lysate of gained；
（4）Wool fabric after padding is irradiated into 3-10min under 100-200W microwaves；
（5）Wool fabric after irradiation is impregnated in methanol solution and solidified, then washes, dry.
The beneficial effects of the present invention are,（1）The limited NMMO aqueous solution is set to be distributed mainly on wool fibre using padding method
The surface of dimension, irradiate and wool surface can only be partly dissolved under the microwave of short time, without damaging wool fiber
Inside, reduce the damage to wool fiber and fabric；（2）In the partly soluble wool egg of wool surface
It is white to form protein compression solution, there is adhesive attraction to nano-particle；（3）The protein compression solution that wool surface is formed exists
Solidified again in methanol solution, play bonding to nano-particle, package action；（4）Any bonding is not used in preparation process
Agent, it is nontoxic.
