Description
Technical field
The present invention relates to a kind of preparation method of function fabric, especially one kind to prepare conductive silk using the NMMO aqueous solution
The method of 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 silk fiber, such as：Absorption method, sol-gal process, layer assembly method, coating, feeding method etc..So
And absorption method is by intermolecular Van der Waals force and ionic forces by mainly making nano-particle be adsorbed onto silk fiber surface, water
It is relatively low to wash fastness；The technical process of sol-gal process and layer assembly method is longer, and more difficult control；Coating is to utilize adhesive
Nano-particle is adhered to silk fiber surface, reduces skin-friendly of the silk fiber to human body；Feeding method is by nano-particle
It is mixed into silkworm food, silk fiber is mixed into nano-particle, shortcoming is that efficiency is very low.
N-methylmorpholine-N- oxides are a kind of white crystals, with certain proportion be dissolved in water water white transparency N- first
The base methylmorpholine-N-oxide aqueous solution, it is mainly used in plant cellulose high-performance solvent.At room temperature, NMMO is only to natural
Fibroin albumen has swelling action；After 100oC, NMMO can thoroughly dissolve silk fiber, obtain the regenerated silk of concentration 20% or so
Protein solution.
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 conductive silk fabric.The technology of preparing is simple and easy, and cost is cheap, to the strength of silk fabric
Damage small, do not change silk fiber surface property, nano conducting powderses have good fastness on silk fabric；This was prepared
Any adhesive is not used in journey, it is nontoxic.
To achieve these goals, the solution taken of the present invention is：One kind prepares conductive silkworm using the NMMO aqueous solution
The method of silk fabrics, it is characterised in that comprise the following steps：
（1）The preparation of lysate：In the NMMO aqueous solution（Mass fraction is 5%-40%）Middle addition nano conducting powderses, are stirred vigorously
Under obtain being dispersed with the lysates of nano conducting powderses；
（2）By silk fabric in step（1）Repeatedly padded in the lysate of gained；
（3）Silk fabric after padding is irradiated into 3-10min under 100-200W microwaves；
（4）Silk fabric after irradiation is impregnated in aqueous povidone 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 silk fibroin using padding method
The surface of dimension, the microwave irradiation of short time can only be partly dissolved to silk fiber surface, without damaging in silk fiber
Portion, reduce the damage to silk fiber and fabric；（2）In the fibroin of silk fiber dissolution of partial fiber surface
Protein compression solution is formed, there is adhesive attraction to nano-particle；（3）The protein compression solution that silk fiber surface is formed is poly-
Solidified again in the vinylpyrrolidone aqueous solution, play bonding to nano-particle, package action；（4）Do not make in preparation process
It is nontoxic with any adhesive.
