Abstract
The invention relates to a method for preparing nanosilver from honey and finishing a cotton linen bamboo fiber fabric. The method comprises the steps: preparing a 0.01-100 g/L aqueous solutions with silver nitrate, then adding a certain amount of honey, under the condition of the temperature of 50 DEG C-90 DEG C, uniformly stirring for 30-600 min, to obtain a nanosilver colloidal solution, repeatedly washing with ethanol and deionized water respectively, centrifuging, carrying out drying treatment to obtain nanosilver particles, then dipping a cotton/linen/bamboo fiber blended fabric to the nanosilver solution with the concentration of 0.01-10 g/L, and dipping for two times and rolling for two times. The honey is used as a reducing agent and a stabilizer for nanosilver, and the method has the advantages of simple process, mild reaction, green environmental protection and the like. The prepared nanosilver is applied in the textile field, and the blended fabric having the bactericidal effect can be prepared, so as to greatly improve the added value of the textile.
Description
Technical field
The invention belongs to field of textiles, particularly a kind of honey is prepared Nano Silver and is arranged the method for cotton linen bamboo fiber.
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.
The honey of honey nectar brew in honeycomb that to be honeybee adopt from the spending of flowering plant.Honeybee takes moisture to be about nectar or the secretion of 80% from the spending of plant, stored in oneself second stomach, under the effect of multiple invertase in vivo, repeatedly ferment various vitamin, mineral matter and amino acid through about 15 days and enrich certain numerical value, simultaneously the polysaccharide in nectar is transformed into simple sugar glucose, the fructose that human body can directly absorb, moisture is less than 10% and is stored in nest hole, seals with beeswax.Honey is the supersaturated solution of sugar, can produce crystallization during low temperature, and what generate crystallization is glucose, does not produce the part mainly fructose of crystallization.Honey is because of the difference of honeybee kind, nectar source, environment, and its chemical composition has very big-difference.Its main component is fructose and glucose, both account for 70%, still containing a small amount of sucrose, maltose, dextrin, natural gum and nitrogen-containing compound, organic acid, volatile oil, pigment, wax, natural perfume material, vegetable debris (particularly pollen grain), yeast, enzyme, inorganic salts etc. at content total.Have no at present with honey is the report that Nano Silver prepared by reductant.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, aim to provide a kind of method that honey is prepared Nano Silver and arranged cotton linen bamboo fiber.
The present invention is achieved by following technical proposals:
