Description
Technical field:
The present invention relates to textile technology fields, and in particular to a kind of preparation method of pet anti-bacterial bamboo charcoal nano-fiber.
Background technique:
Nowadays the requirement with people to dress ornament is higher and higher, and the dress ornament made of anti-bacterial fibre will will receive the joyous of people
It meets.Simultaneously as the continuous reduction of petroleum resources, renewable resource obtains more and more development, especially environmentally friendly requirement.
And bamboo charcoal is from a wealth of sources, preparation is simple, while meeting the requirement of environmental protection again.Most importantly, bamboo charcoal fiber has good excellent
Point.Bamboo charcoal has special structure, and molecular structure is hexagon, and carbonaceous is fine and close, and than great, hole is more.Containing potassium, magnesium, iron,
The natural mineral matter abundant such as calcium, zirconium, large specific surface area have preferable absorption, smelly eliminating, moisture absorption, antibacterial and far infrared, anti-purple
Outside, anion emission function, therefore obtained the development and application of textile industry.
But at present from the processing of bamboo charcoal fiber and application, there are still above-mentioned functions to fail to give full play to, especially antibacterial
Function.Current anti-bacterial fibre is using the modified method of precursor and post treatment method, and wherein the modified method of precursor can generate lousiness and broken end, no
It can obtain the fiber of preferable slippery feel；Post-processing will use some antibacterial agents, especially some metallic element such as lead, and copper exists
Among fiber, because it will be with human contact, it will generate certain harm to human body；In addition, some antibacterial agents pass through leaching
Stain, the modes such as absorption handle fiber surface, and fiber is by repeatedly washing, it is also possible to so that antibacterial agent is fallen off, antibacterial
Effect will reduce.By analyzing above, it is seen that the defect of the prior art.
Pet due to often in outer migration, run, itself become easily infected by bacterium, and itself active mill for frequently resulting in dress material
Damage, cracking.
Summary of the invention:
Technical problem to be solved by the present invention lies in overcoming the deficiencies of the prior art and provide, a kind of antibacterial agent dispersion is equal
It is even, not easily to fall off, durable antibacterial effect, intensity height, anti abrasive pet anti-bacterial bamboo charcoal nano-fiber.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
A kind of preparation method of pet anti-bacterial bamboo charcoal nano-fiber, comprising the following steps:
(1) it pre-processes: nano bamboo powdered carbon being add to deionized water, 10-30min is stirred under ultrasound condition, filter,
Drying is spare to constant weight；
(2) preparation of antibacterial matrices: by nano bamboo powdered carbon, nano-silver powder, carrier slice, antioxidant, dispersing agent, activity
Additive is mixed evenly, and is then fed into double screw extruder, is kneaded, pelletizing, and required antibacterial matrices are made；
(3) preparation of anti-bacterial fibre: antibacterial matrices and required carrier slice are mixed according to a certain percentage,
Through melt composite spinning, cooling down, volume burning, drawing-off, sizing, required fiber is made.
Nano bamboo powdered carbon in the step 2, nano-silver powder, carrier slice, antioxidant, dispersing agent, active additive
Mass ratio are as follows: 1-20:1-10:60-80:0.1-0.5:1-3:0.1-0.5.
The melting temperature is 230-280 DEG C, and pressure is 6.5-8MPa in extruder, mixing speed be 280-350 turn/
Point.
Antibacterial matrices in the step 3, carrier slice mass ratio be 80-100:2-5.
The temperature of the melt spinning is 270-290 DEG C, cooling 24-28 DEG C of temperature of blowing, wind speed 0.5-3 meter per second, wind
Relative humidity 65~80%, 900-1400 ms/min of draft speed.
The nano-silver powder the preparation method comprises the following steps:
(1) nano silver is washed in deionized water under ultrasonic wave effect, to remove its surface miscellaneous after being filtered, being dried
Matter；
(2) starch is weighed, the starch milk of 40g/100mL is modulated into distilled water, is then 5-10% salt with mass fraction
Acid for adjusting pH is 5.5-6, is then slowly added into 'alpha '-hydroxy acids and sodium peroxydisulfate, is heated to reflux state, insulated and stirred 2-6h, 35
DEG C filtering, obtained solid is washed with deionized water decontamination, is sent into 100-110 DEG C of drying box, dry to form sediment to constant weight to get modified
Powder；
(3) pretreated nano silver and modified starch are mixed and is placed in ball-milling treatment 10-30min in ball mill, so
Glycerin monostearate and dehydrated alcohol are added afterwards, continues ball milling 0.5-2h, filters to get nano-silver powder is arrived.
The nano silver, starch, 'alpha '-hydroxy acids, sodium peroxydisulfate, glycerin monostearate, dehydrated alcohol mass ratio be
10-20:20-30:5-10:0.1-0.2:1-5:5-10.
The starch is selected from one of cornstarch or potato starch.
The active additive the preparation method comprises the following steps: hydroxymethyl cellulose is add to deionized water, be warming up to 50-60
DEG C stirring 10-30min, is then added hydrolysis of polymaleic anhydride and tetraethyl titanate, is heated to reflux state, insulated and stirred 0.5-
Then castor oil is added in 3h, continue to stir 10-30min, filter while hot, and decontamination is washed with deionized water in gained precipitating, is sent into true
In empty drying box, dry to constant weight to get active additive is arrived.
The hydroxymethyl cellulose, hydrolysis of polymaleic anhydride, tetraethyl titanate, castor oil mass ratio be 10-20:10-
20:0.1-0.2:1-3.
Carrier in the carrier slice is selected from one of terylene, polypropylene fibre, polyamide fibre.
The antioxidant is selected from one of antioxidant 1010 or 168.
The dispersing agent is polyethylene glycol 400.
After bamboo charcoal powder partial size reaches nanoscale, specific surface area increases, surface can enhance, prominent function, major function
As adsorptivity, far infrared, anion function are more obvious, while there is certain bacteria resistance function, but it cannot sterilize, sterilize, leads to
It crosses and the combination of nano silver, can solve and improve significantly its antibacterial functions.
Partial size is exactly accomplished nanoscale metallic silver simple substance by nano silver, and partial size is mostly in 25 rans.Nano silver is made
For antibacterial agent using when maximum problem be exactly it is easy to reunite and it is easy fall off from fiber, cannot be evenly dispersed in the base, directly
Connecing leads to increase difficulty in spinning and anti-microbial property is caused to decline or lose.By the combination of modified starch and nano silver, can make
Nano silver is uniformly dispersed in PET matrix, improves spinnability and fibre antibacterial performance.
The beneficial effects of the present invention are:
(1) present invention is modified processing to starch using 'alpha '-hydroxy acids, expands the intermolecular distance of starch and to nothing
The adsorptivity of machine metal, it is by the catalytic action of glycerin monostearate and dehydrated alcohol, nano silver and starch progress is organic
In conjunction with, make nano silver itself be not susceptible to assemble, improve its dissolution in carrier slice, dispersibility, make it have preferably
Antibacterial effect；
(2) present invention prepared by active additive have adhesive property and more active group so that nano silver with
Unsaturated group on fiber is connected by chemical bond, improves adhesion of the nano silver on fiber, and then improves the anti-of fiber
Bacterium persistence, while the physical strength and wear resistance of fiber can be enhanced；
(3) bamboo charcoal fiber prepared by the present invention has excellent absorption, hygroscopicity, and wear-resistant, anti-microbial property is excellent, fits
Production for pet clothes；Bamboo charcoal is renewable resource simultaneously, from a wealth of sources, economic and environment-friendly.
