Abstract
The invention relates to a preparation method of silver-carrying antibacterial blended fabric. A thymol solution with the concentration being 0.01 g/L-1 g/L is mixed with a silver nitrate solution with the concentration being 0.01 g/L-100 g/L in the volume ratio being (100:1)-(1:1), the mixture is stirred at a constant speed for 10-600 min at the temperature ranging from 30 DEG C to 80 DEG C, a nano-silver colloidal solution is obtained, washed repeatedly with ethyl alcohol and deionized water and subjected to centrifugation and drying processing, nano-silver particles are obtained, then cotton/linen/bamboo fiber blended fabric is soaked in the nano-silver solution with the concentration being 0.01 g/L-10 g/L, soaking and rolling are performed twice respectively, and then the silver-carrying antibacterial blended fabric is obtained. With thymol serving as a reducing agent and a stabilizer, the preparation method has the advantages of simple process, mild reaction, environment protection and the like. Prepared nano-silver is used for the field of textiles and can be used for preparing fragrant, anti-corrosive, anti-bacterial and acarus-killing blended fabric with multiple functions including dermatomycosis and tinea prevention and the like, and the additional value of the fabric is greatly increased.
Description
Technical field
The invention belongs to field of textiles, particularly a kind of preparation method of Ag-carried antibacterial BLENDED FABRIC.
Background technology
Textiles is acknowledged as the medium of cooperating microorganisms as bacterium, fungi.The microbiologic population of occurring in nature is present in the environment of surrounding widely, can grow rapidly once run into suitable humidity, nutrient and temperature.The microorganism grown on the textile not only affects textiles self serviceability, and has influence on the health of user.Therefore how suppressing or killing the microorganism being attached to textiles is especially textiles industry problem in the urgent need to address.
Antibacterial fabric can improve value-added content of product, meets the demand of people to health environment-friendly, and be therefore more and more subject to the attention of vast textile research person, market potential is very large.In the research field of antibacterial fabric, the application of nano silver antimicrobials is the important channel realizing antibacterial textile performance.Silver-series antibacterial agent has many good qualities: one is that antibacterial activity is high, and particularly in the environment of warm moist, it is active that silver-series antibacterial agent has stronger biological antibiotic, when the concentration of silver ion is 10
-6during level, just there is certain fungistatic effect, have in the metal ion of antibacterial action numerous, the ability of its sterilization and suppression pathogen has following rule: Ag>>Hg>CuGreat T.GreaT.GTCd>Cr>NiGreatT.Gre aT.GTPb>Co>Zn> Fe; Two is very high securities, and do not have the change of obvious cell aggregation, cytomorphosis, cytolysis and pH value etc. with the cell after the silver ion treatment that concentration is very low, silver ion a small amount of does not as seen have obvious injury effect to human body; Silver-series antibacterial agent also not easily develops immunity to drugs simultaneously, has good durability.Greatly, the particle of silver is less, and antimicrobial efficiency is higher, and therefore in silver-series antibacterial agent, nano silver antimicrobials especially receives and pays close attention to widely for the antimicrobial efficiency of silver-series antibacterial agent and its surface area relationship.Nano Silver refers to that particle diameter is less than 100 nm, approximately containing 20-15, and the Argent grain of 000 silver atoms.Nano Silver, because having small-size effect, skin effect, quantum size effect and macro quanta tunnel effect etc., shows and is different from conventional physics, chemistry and biological property, comprises excellent anti-microbial property.
The preparation of traditional Nano Silver is divided into Physical and chemical method.Physical requires higher to instrument and equipment, and producing cost is expensive.Chemical method many employings hydrazine hydrate, formaldehyde, polyalcohol, organic amine etc. make reductant, although these reductants have high activity, to bad environmental, and obtained Nano Silver easily agglomeration occurs.
In recent years, green, environmental protection, efficient and cheap method is adopted to prepare the focus that Nano Silver becomes research gradually, compared to physics, chemical method advantageously, wide material sources, reaction condition is gentle, just can react at normal temperatures and pressures, the nano silver particles of synthesis has good biocompatibility.The green reducing agent adopted at present mainly comprises: vitamin, natrium citricum, pyrogallol, hydroquinones, Tea Polyphenols, glucose, fructose, sucrose, plant and pericarp extract, microorganism etc.
Thymol (thymol), another name thymol, thymol, flaky crystal, is very easily dissolved in ethanol, ether, acetic acid, chloroform and benzene.Naturally be present in labiate Thymus plant, there are pungent perfume (or spice) and the hay-scented fragrance of Thymus plant, be phytovolatilization main body of oil (containing about 50%), available sodium phenolate method is out isolated from plant volatile oil, more namely drying, decompression distillation obtain product.Thymol can be used as flavorant, preservative agent medically and bactericide.Thymol has very strong acaricidal action, and the solution 24h of 1% solution death rate half an hour 100%, 0.03% kills 100%.
Chinese invention patent 201310291305.8: adopt suitable, the trans-3-(2 of anti-mite active matter 3-benzene chloro benzyl (IRS) that anti-mite textiles is conventional; 2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid ester prepares Nano Silver as protective agent; Nano Silver can be made to realize the double effects of antibacterial and anti-mite, and the antibiosis anti-acarien Complex Function being suitable for textiles arranges simultaneously.But Permethrin is mainly used in low toxic pesticide, may be used for various pests on control cotton, vegetables, tealeaves, fruit tree, be particularly suited for the control of sanitary insect pest, be not suitable for the textiles of Long Term Contact human body skin.And it still needs to adopt the one in sodium borohydride, potassium borohydride, hydrazine hydrate, vitamin C, reducibility glucose to carry out reducing nano-silver as reductant.
