Obtaining silver nano-grain and form carrying nano silver fluff pulp fibers, described carrying nano silver fluff pulp fibers, drying of manufacturing paper with pulp obtains antibacterial
Property flossy pulp-board, and filtrate is recycled.
Testing result shows: made antibiotic property flossy pulp-board and Time of Fluff Slurry quality reach the requirement of GB/T21331-2008.
The flossy pulp-board made according to the preparation method of the present invention, its quantification of 600g/m2Time, the burst index of flossy pulp-board is
0.36kPa·m2/ g, after napping, dry bulkiness is 23.6 cm3/ g, absorption speed reaches 4.2s, and water absorption is 10.1g/g, reaches
The quality requirement of GB/T21331-2008, and Time of Fluff Slurry has certain antibiotic property, and testing result is as shown in table 1.
Antibacterial activity detects:
The carrying nano silver Time of Fluff Slurry composite that the present invention is prepared with embodiment 1-3 carries out antibacterial activity test.
Using Escherichia coli as the Gram-negative bacteria of model, staphylococcus aureus as the Gram-positive of model
Bacterium, uses inhibition zone method that sample is carried out bacteriostasis property test, and its specific operation process is as follows:
1, the preparation of culture medium
By beef extract 3g, peptone 5g, sodium chloride 5g, add agar 15g, add in distilled water and be settled to 1000mL, add
Entering the sodium hydroxide solution of 0.1mol/L, regulate pH to 7.2-7.4, heating is boiled, and makes agar dissolve, and loads in conical flask,
Culture medium 0.1Mpa high pressure steam sterilization 15 ~ 20min.Gained solution is the nutrient agar after sterilizing, after solidification
Obtain solid nutrient medium.
Culture medium does not adds agar, is then liquid nutrient media after sterilizing.
2, the cultivation of bacterium
Escherichia coli (coli strain is ATCC8099), (staphylococcus aureus strains is staphylococcus aureus
ATCC29213) it is added separately to be not added with in the fluid nutrient medium of agar, at 37 DEG C, cultivates 18 ~ 24h.Before using, by large intestine
Bacillus, staphylococcus aureus are diluted to 1 × 10 respectively8CFU/ mL ~ 5×108CFU/ mL。
3, carrying nano silver Time of Fluff Slurry embodiment 1-3 prepared is pressed into the disc of a diameter of 1.6cm size in advance,
At 121 DEG C, sterilizing 30min, standby；
Nutrient agar after sterilizing is poured in disposable sterilized culture dish, treats that the temperature of culture medium is down to 40-
45 DEG C, add the certain density bacterium solution of 0.5mL, culture medium is mixed with bacterium solution, treat that nutrient agar cooling is solidifying
After Gu, with tweezers, the most compressing load silver Time of Fluff Slurry disk is put in culture dish gently.Sample is placed on Escherichia coli
Or after on the culture medium of staphylococcus aureus, cultivate 24 hours at 37 DEG C, observe the size of inhibition zone.Bacteriostatic test is seen
Examine result as shown in Fig. 1 and table 1.
Time of Fluff Slurry is mainly carried out antibacterial modified by the present invention, and silver has excellent antibiotic property, extensively should as antiseptic
In all trades and professions, the present invention passes through chemical reduction method, obtains load at fluff pulp fibers cellulose fiber surface reduction silver ion and receives
The fluff pulp fibers cellulose fiber of meter Yin, carries out antibacterial modified to it on the basis of ensureing Time of Fluff Slurry general performance, gives fine hair
Starch certain anti-microbial property.Time of Fluff Slurry after antibacterial modified, is applied in disposable medical amenities, such as baby
In the product such as paper diaper and sanltary towel, can effectively suppress growing of bacterium in use, help the health of protection human body.
The general principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and specification
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
