Abstract
The invention provides a kind of method that fluorescent natural silk fabric is prepared using ionic liquid, this method comprises the following steps：（1）The preparation of lysate：Ionic liquid is added in absolute ethyl alcohol, forms the mixed solution of concentration 0.1% 10%, fluorescent material nano-particle is then added in mixed solution, obtains being dispersed with the lysate of fluorescent material nano-particle under sonic oscillation；（2）By silk fabric in step（1）Repeatedly padded in the lysate of gained；（3）Silk fabric after padding is removed into ethanol, vacuum 0.1MPa, temperature 50oC in vacuum desiccator；（4）The silk fabric for removing ethanol is irradiated under infrared ray；（5）Silk fabric after irradiation is impregnated in Aqueous Solutions of Polyethylene Glycol and solidified, then washes, dry.This technology of preparing is simple and easy, and cost is cheap, small to the strength damage of silk fabric, does not change silk fiber surface property, and fluorescent material nano-particle has good fastness on silk fabric；Any adhesive is not used in this preparation process, it is nontoxic.
Description
Technical field
It is especially a kind of to be knitted using ionic liquid preparation fluorescent natural silk the present invention relates to a kind of preparation method of function fabric
The method of thing.
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.
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 silk-fibroin dissolving
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 fluorescent natural silk fabric.The technology of preparing is simple and easy, and cost is cheap, to the strength damage of silk fabric
It is small, do not change silk fiber surface property, fluorescent material nano-particle has good fastness on silk fabric；The preparation process
In be not used any adhesive, it is nontoxic.
To achieve these goals, the solution taken of the present invention is：One kind prepares fluorescent natural silk using ionic liquid
The method of fabric, it is characterised in that comprise the following steps：
（1）The preparation of lysate：Ionic liquid is added in absolute ethyl alcohol, forms concentration 0.1%-10% mixed solution, so
Fluorescent material nano-particle is added in mixed solution afterwards, obtains being dispersed with the lysate of fluorescent material nano-particle under sonic oscillation；
（2）By silk fabric in step（1）Repeatedly padded in the lysate of gained；
（3）Silk fabric after padding is removed into ethanol in vacuum desiccator, vacuum is -0.1MPa, temperature 50oC；
（4）The silk fabric for removing ethanol is irradiated into 10-30min under infrared ray；
（5）Silk fabric after irradiation is impregnated in Aqueous Solutions of Polyethylene Glycol 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 silk fiber, the microwave irradiation of short time can only be partly dissolved to silk fiber surface, without damaging silkworm
Inside silk fiber, reduce the damage to silk fiber and fabric；（2）In silk fiber dissolution of partial fiber surface
Fibroin forms protein compression solution, has adhesive attraction to nano-particle；（3）The protein compression that silk fiber surface is formed
Solution solidifies again in Aqueous Solutions of Polyethylene Glycol, plays bonding to nano-particle, package action；（4）In preparation process not
It is nontoxic using any adhesive.
