Abstract
The invention discloses a preparation method of a silver/chitosan composite antibiotic finishing agent. The preparation method comprises the following steps: 1, dissolving AgNO3 in water to prepare a 0.5g/L AgNO3 solution; 2, dissolving chitosan in a 0.5mol/L aqueous solution of acetic acid, adjusting the pH value to 4.5-5.5 by sodium hydroxide, and dissolving for 5-10min to prepare a chitosan-acetic acid solution; and 3, adding the 0.5g/L AgNO3 solution to the chitosan-acetic acid solution, adding a finishing aid, uniformly stirring at 20-30DEG C, and allowing an obtained material to stand for 4-6h to obtain the silver/chitosan composite antibiotic finishing agent. The preparation method of the silver/chitosan composite antibiotic finishing agent has the advantages of simple operation, low cost, obviously improved antibiotic performance of textiles finished by the silver/chitosan composite antibiotic finishing agent, and good launderability.
Description
Technical field:
The present invention relates to the nano-antibacterial technical field, relate in particular to the preparation method of a kind of silver/chitosan composite antibiotic finishing agent.
Background technology:
Various textiless used in daily life, as sheet, bed clothes, underwear, shoe-pad, socks, towel, cushion etc., all suitable places of microbial growth procreation, in the environment of high temperature and humidity, these microorganisms are growth and breeding rapidly, not only can make that fibre is mouldy, rotten, variable color is even decomposed, also can infect various germs by these textiless.Natural biological antiseptic shitosan is the abundant chitinous de-acetyl products of natural reserves, very strong biocompatibility and biodegradable are arranged, the chitosan molecule chain contains the acetamido of 1-2% usually, amino energy in molecule and the anion binding of bacterial cell wall surface, hinder its biosynthesis and play antibacterial action, but effect is not as silver or organic antibacterial agent.Along with nano molecular is easily reunited, and the solution of the problem such as easily sulfuration and oxidation of silver, photostability be poor, there is the Nano Silver inorganic antiseptic that the good and antibiotic timeliness of security such as grows at the advantage, more and more receive publicity.Carry out the complexing processing with shitosan and silver ion, obtain the compound x type of silver/shitosan antibacterial finishing agent, have both advantages concurrently, can effectively improve anti-microbial property.
Summary of the invention:
The preparation method of a kind of silver of purpose of the present invention/chitosan composite antibiotic finishing agent, the method is simple to operation, and the silver of preparation/chitosan composite antibiotic finishing agent has good anti-microbial property after fabric is arranged.
Purpose of the present invention is achieved through the following technical solutions:
The preparation method of a kind of silver/chitosan composite antibiotic finishing agent comprises the following steps:
(1) by AgNO
3soluble in water, the AgNO of preparation 0.5g/L
3solution;
(2) shitosan is dissolved in the 0.5mol/L aqueous acetic acid, and regulates its pH value to 4.5-5.5 with NaOH, dissolve 5-10min, make chitosan-acetic acid solution;
(3) get the AgNO of 0.5g/L
3solution adds in above-mentioned chitosan-acetic acid solution, and adds and help finishing agent, and 20-30 ℃ stirs, and places 4-6h, obtains described silver/chitosan composite antibiotic finishing agent.
As technique scheme preferably, the described finishing agent that helps is one or both in sodium chloride, potassium chloride, sodium sulphate, potassium sulfate.
Beneficial effect of the present invention is: the preparation method of silver provided by the invention/chitosan composite antibiotic finishing agent is simple to operate, cost is low, after using silver/chitosan composite antibiotic finishing agent to be arranged fabric, the anti-microbial property of fabric obviously improves, and after repeatedly washing, fabric still has anti-microbial property preferably, illustrates that the washing resistance of this fabric is good.
The specific embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
Embodiment 1: the 10g shitosan is dissolved in the 150ml aqueous acetic acid, and regulates its pH value to 4.5 with NaOH, dissolve 5min, make chitosan-acetic acid solution; Get the AgNO of 40ml 0.5g/L
3solution adds in above-mentioned chitosan-acetic acid solution, and adds 0.2g sodium chloride, and 20-30 ℃ stirs, and places 4h, obtains silver/chitosan composite antibiotic finishing agent.Fabric after the silver that use obtains/chitosan composite antibiotic finishing agent is arranged after fabric is soaked-rolls, bakes, carry out the anti-microbial property test to the fabric after arranging, and the results are shown in Table 1.
Embodiment 2: the 10g shitosan is dissolved in the 165ml aqueous acetic acid, and regulates its pH value to 5 with NaOH, dissolve 5min, make chitosan-acetic acid solution; Get the AgNO of 50ml 0.5g/L
3solution adds in above-mentioned chitosan-acetic acid solution, and adds 0.3g potassium chloride, and 20-30 ℃ stirs, and places 5h, obtains silver/chitosan composite antibiotic finishing agent.Fabric after the silver that use obtains/chitosan composite antibiotic finishing agent is arranged after fabric is soaked-rolls, bakes, carry out the anti-microbial property test to the fabric after arranging, and the results are shown in Table 1.
Embodiment 3: the 10g shitosan is dissolved in the 170ml aqueous acetic acid, and regulates its pH value to 5.5 with NaOH, dissolve 10min, make chitosan-acetic acid solution; Get the AgNO of 40ml 0.5g/L
3solution adds in above-mentioned chitosan-acetic acid solution, and adds 0.5g sodium sulphate, and 20-30 ℃ stirs, and places 6h, obtains silver/chitosan composite antibiotic finishing agent.Fabric after the silver that use obtains/chitosan composite antibiotic finishing agent is arranged after fabric is soaked-rolls, bakes, carry out the anti-microbial property test to the fabric after arranging, and the results are shown in Table 1.
Table 1
As shown in Table 1, after using silver/chitosan composite antibiotic finishing agent to be arranged fabric, the anti-microbial property of fabric significantly improves, and Escherichia coli reduce percentage and reach more than 90%, and after 20 washings, fabric still has good antibacterial effect.
