Technical field
The present invention relates to the Multifunctional cotton fiber based on nano silver wire/chitosan/fibroin, belongs to textile material field.
Background technology
Cotton fiber is with the performance such as its excellent moisture absorption, ventilative, comfortable, soft, warming, renewable, degradable by vast
Consumer's likes.But compared with synthetic fibers, the feature of cotton fiber still has deficiency.Such as：（1）Cotton fiber have than
The features such as surface area is greatly and wettability power is strong, thus easily adhere to, breed and propagate microorganism during taking, so as to cause
Cotton fiber strength declines, produces stain, colour fading and smell, or even spreads disease, and influences health.（2）Excessive ultraviolet
Irradiation can cause skin injury, aging, or even cause canceration.（3）Conductive spinning product is increasingly becoming the focus of research in recent years, leads
Electric bafta has huge application value in flexible wearable equipment.Therefore in order to fully excavate the potential function of cotton fiber,
The technology content and added value of product of cotton fiber are improved, carrying out functional modification to cotton fiber turns into an important research direction
（The preparation of dissaving polymer and functional modification [D] the University Of Suzhou to cotton fiber, 2009）.
Inorganic nano material refers to that size is in 1-100nm material, relative to other nano materials, inorganic nano material
With preparing simple, the advantage such as cost is cheap, uniform particle diameter, photocatalysis, solar cell, biology, medicine, weaving, printing and dyeing,
There are extensive research and application in the fields such as wearable electronic.In the inorganic nano material of numerous types, Nano Silver accounts for
According to important position, Nano Silver is combined with cotton fiber can be effectively improved cotton fiber inherent shortcoming, expand cotton fiber and be applicable
Scope, improve cotton fiber added value.Lot of documents is reported using after nano-Ag particles modified cotton fiber, and it is excellent can to assign cotton fiber
The performances such as different antibacterial, uvioresistant, conduction, electromagnetic shielding.But above-mentioned document is modified cotton using the silver nano-grain of zero dimension more
Fabric.Such as Zhang carries out antibiotic finish to bafta using Nano Silver, bafta after arrangement to staphylococcus aureus and
The bacteriostasis rate of Escherichia coli is respectively 99.01% and 99.26%, and after 20 washings, bacteriostasis rate is still up to 98.77%（Fibers
and Polymers, 2009, 10(4): 496-501）.
The nano silver wire of one-dimentional structure has high-specific surface area, heat conduction, conduction, printing opacity, ductility, mechanical strength and flexibility
Etc. performance, there is potential application value in fields such as flexible conductive film, solar cell, touch-screen, display screen, sensors
（Chinese material is in progress, 2016 (07): 545-551）.The existing research on nano silver wire modifying textile fibres on a small quantity at present
Report（Based on the electronic textile of nano silver wire conductive network, chemical progress, 2017,29 (8): 892-901）.Iran she
Si Lan Free University Nateghi uses AgNWs modified cotton fabrics, and have studied the antibacterial, uvioresistant, conduction of modified bafta
And ultra-hydrophobicity（Carbohyd. Polym., 2015, 117:160）.Canadian University of Waterloo (CA) Waterloo, Ontario, N2L3GI Canada Atwa is by impregnating-carrying
Daraf(reciprocal of farad) coats AgNWs conductive networks on cotton thread surface, then anneals 30 minutes for 150 DEG C, so as to which conductive cotton thread be prepared（J.
Mater. Chem. C, 2015, 3(16):3908）.Polish textile science research institute Cies ' lak are whole using dipping-oven drying method
Manage bafta（Cellulose, 2017, 24(1):409）.University Of Suzhou repaiies A Nan and bafta is immersed in AgNWs solution
Carry out antibacterial, anti UV finishing（It is whole to repair the amphiphilic hyper-branched polyglycidyl ethers of A Nan, the preparation of nano silver wire and bafta
Reason pre-test [D] University Of Suzhou, 2015）.Cotton is soaked in nano silver wire/second by Chinese invention patent CN201610217104.7
In alcohol dispersion liquid, take out and be soaked in again in above-mentioned dispersion liquid after drying, the repeated multiple times adsorption that obtains has nano silver wire
Conductive cotton.Nanjing Univ. of Posts and Telecommunications Zhang Ziqiang induces the method for self assembly that AgNWs is assembled in into nylon yarn first with capillary
On, AgNWs conductive yarns are obtained, then the AgNWs conductive yarns prepared are immersed in silk fibroin solution and carry out secondary assembling,
Finally fibroin is reduced again, obtains the AgNWs conductive yarns of graphene parcel with preferable mechanical performance and adhesion property（
Electrical-conductive nanometers material improve oneself in the capillary self assembly of fiber surface and performance study [D] Nanjing Univ. of Posts and Telecommunications, 2016）.But
Effect in above-mentioned document between AgNWs and fiber mainly based on physical absorption existing for Van der Waals force and hydrogen bond formation, lacks
Weary firm active force combines, and its fastness to washing is on the weak side.
The content of the invention
In view of the above problems, the present invention provides the Multifunctional cotton fiber based on nano silver wire/chitosan/fibroin and its
Preparation method.
The technical scheme is that：
（1）Bafta is placed in the sodium hydroxide solution that mass fraction is 20%, bath raio 1:50,90 DEG C of reaction 120min, are used
Deionized water is washed till neutrality repeatedly, and sodium hydroxide modified cotton fabric is obtained after drying；Then by sodium hydroxide modified cotton fabric weight
Newly it is scattered in deionized water, bath raio 1:50, add trimethylallylammonium chloride, wherein trimethylallylammonium chloride and hydrogen
