Abstract
The invention relates to a method for preparing silver-carrying antibacterial blended fabric by instant coffee. The method comprises the following steps: mixing 0.01-10 g/L instant coffee solution and 0.01-100 g/L silver nitrate solution according to the volume ratio of 10:1 to 1:10; stirring the mixture for 10 to 600 minutes at a uniform speed at the temperature of 30 to 80 DEG C to obtain a nano-silver colloid solution; washing the nano-silver colloid solution repeatedly by using ethyl alcohol and de-ionized water; centrifuging, and drying to obtain silver nano-particles; soaking cotton/linen/bamboo fiber blended fabric into the nano-silver solution with the concentration of 0.01-10 g/L; and soaking twice and rolling twice. According to the method for preparing the silver-carrying antibacterial blended fabric by the instant coffee, the commercially available instant coffee serves as a reducing agent and a stabilizing agent; and the method has the advantages of simplicity, mild reaction, greenness, environmental friendliness and the like. The prepared nano-silver is used in the field of textiles; the blended fabric with sterilization efficacy can be prepared; and the additional values of the textiles are greatly improved.
Description
Technical field
The invention belongs to field of textiles, particularly the method for Ag-carried antibacterial BLENDED FABRIC prepared by a kind of instant coffee.
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 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 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.
Instant coffee is the coffee-extract by the drying moisture evaporation in coffee extract obtained.Instant coffee can very fast dissolving in the hot water, and the space taken in storage and transport process and volume less, more for shelf-stable.Be different from comparatively complicated traditional coffee and brew mode, therefore obtain popular widely.Containing all multicomponents such as caffeine, maltodextrin, sugar, stabilizing agent, protein, tannic acid, vitamins in instant coffee, but have no the bibliographical information directly instant coffee being used for reducing nano-silver at present.
Summary of the invention
