Abstract
The invention relates to preparation of nano-silver particles and application of the nano-silver particles. A thymol crystal solution of 0.01-1 g/L and a silver nitrate solution of 0.01-100 g/L are mixed according to the volume ratio of 100:1-1:1; the mixture is stirred for 10-600 min at a constant speed under the temperature condition of 30-80 DEG C, and a nano-silver colloidal solution is obtained; and ethyl alcohol and deionized water are used for repeated cleaning, centrifuging is conducted, and the nano-silver particles are obtained after drying processing. According to the preparation of the nano-silver particles and application of the nano-silver particles, thymol crystals are used as a reducing agent and a stabilizing agent, and therefore the beneficial effects of being simple in technology, moderate in reaction, environmentally friendly and the like are achieved. Nano-silver prepared through the preparation is applied to the field of textiles, cotton/cashmere/spun silk blended fabric which has multiple effects of emitting fragrances, resisting corrosion, killing bacteria, removing mites, preventing skin mycoses and tinea and the like can be prepared, and the additional value of textiles is greatly improved.
Description
Technical field
The invention belongs to field of textiles, particularly a kind of preparation of nano silver particles and application thereof.
Background technology
Textile 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 textile self serviceability, and has influence on the health of user.Therefore how suppressing or killing the microorganism being attached to textile is especially textile 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 100nm, 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 reducing agent, although these reducing agents 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, anticorrisive 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 textile 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 textile 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 textile of Long Term Contact human body skin.And it still needs to adopt the one in sodium borohydride, potassium borohydride, hydrazine hydrate, vitamin C, reproducibility glucose to carry out reducing nano-silver as reducing agent.
Summary of the invention
