Abstract
The invention discloses a method for producing silver-carrying antibacterial sisal fibers, which includes: soaking sisal fibers 0.4-0.6g in detergent for 2-3 hours, rubbing with hands to clean the fibers, washing the fibers with distilled water, and drying the fibers to stand by; soaking the dried sisal fibers in sodium hydroxide solution with a weight fraction 2% for 8 hours, cleaning the sisal fibers until the fibers are neutral, and drying the sisal fibers to stand by; placing the obtained sisal fibers in a Soxhlet extractor for extraction for 24 hours, obtaining extract which is mixed liquor of absolute ethyl alcohol and analytically pure cyclohexane in a volume ratio 1:1, and drying the extracted sisal fibers to stand by; and placing the extracted sisal fibers in 35-45ml of silver nitrate solution with molar concentration 10mmol/L, allowing to stand under an ultraviolet lamp with wavelength 253.9nm and power 20w for 55-65 minutes, cleaning the sisal fibers with distilled water, and placing the cleaned sisal fibers in a drying box with constant temperature 50 DEG C and drying the sisal fibers to obtain the antibacterial sisal fibers. The antibacterial sisal fibers are nontoxic and efficient in antibiosis. The method of ultraviolet irradiation reduction has the advantages of high reduction efficiency and reaction availability at normal temperature.
Description
Technical field
The present invention relates to the chemical plating of non-metal material field, particularly a kind of preparation method of Ag-carried antibacterial sisal fiber.
Background technology
Sisal hemp, the herbaceous plant that as a kind of common agave, be that a class is perennial, meat, drought is given birth to mainly obtains fiber from leaf sheath.Sisal hemp is that world today's consumption is maximum, a kind of hard fibre widest in area has that pure white, strong but pliable in texture (pulling force is strong), springiness, sea water resistance soak, rub resistance, is difficult for cataclasmly, and colloid is few, the characteristic such as be difficult for skidding is the Main Economic crop that produces hard fibre.In recent years, sisal hemp (SF) is as a kind of fiber of ecosystem, has wide, economic, renewable etc. the advantage in source, the extremely attention of the every field such as enterprise, scientific research and concern.Traditionally, sisal fiber mainly is to make white palm rope, is applied to the aspects such as industrial and mineral, electric power, metallurgy, transportation, agricultural fishing, lumber, navigation.The economic benefit of sisal fiber mainly is to embody by development deep processing, increase added value of product, so the functionalization research of sisal fiber has important society and economic implications.Researching and developing new anti-bacterial fibre is of paramount importance problem in the field of functional materials, continually developing the sisal fiber new product, improve its attached value, is the developing direction of sisal fiber research, and the research of sisal based anti-bacterial fibre, for the sisal fiber functionalization has been opened up a new approach.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of Ag-carried antibacterial sisal fiber.
Concrete steps are:
(1) knot is smart to be soaked 2-3 hour with washing with the 0.4-0.6g sisal fiber, and then hand rubbing is extremely clean a little, again with the distilled water washing, to remove the impurity dry for standby on sisal hemp surface;
(2) it is in 2% the sodium hydroxide solution 8 hours that the sisal fiber that step (1) is made is soaked in weight fraction, and then washing is to neutral, to remove the lignin in the sisal fiber, the pectin dry for standby;
(3) sisal fiber that step (2) is made places apparatus,Soxhlet's to extract 24 hours, and extract is 1: 1 absolute ethyl alcohol of volume ratio and the mixed liquor of analyzing pure cyclohexane, to remove the pectin in the sisal fiber, dry for standby;
(4) it is the 10mmol/L liquor argenti nitratis ophthalmicus that the sisal fiber that step (3) is made is put into the 35-45mL molar concentration, being placed on wavelength is 253.9nm, power is 55-65min under the uviol lamp of 20W, then sisal fiber is used the distilled water washes clean, placed 50 ℃ of thermostatic drying chamber inner dryings can make antibacterial sisal fiber.
Utilize ESEM to carry out morphology characterization to carrying silver-colored sisal fiber, can find out obviously that the particle of existence is dispersed in the sisal fiber surface with nanoscale, silver-colored particle is not reunited.Utilize EDS that the particle that the sisal fiber surface exists is carried out elementary analysis, thereby the particle of having determined Nano grade is silver, and is only to have C, H, three kinds of elements of Ag.Utilize the examination of infrared spectrum instrument that it is carried out test analysis, what the result showed the main dependence of silver is that non-bonding is combined with sisal fiber.
Advantage of the present invention is:
One, selects silver as antiseptic, have high-efficiency antimicrobial, have in addition the eco-friendly advantages such as nontoxic; Select the method for UV-irradiation reduction, have the advantages such as reduction efficiency height, normal temperature can react.
Two, the matrix-sisal fiber of enforcement chemical plating contains hydrophilic radical, and namely water imbibition well is attracted in sisal fiber surface and the structure space liquor argenti nitratis ophthalmicus, thereby makes the silver particles that makes well load on the sisal fiber surface.
Three, antibacterial sisal fiber is dipped in the aqueous solution, antiseptic can be lasting within the regular hour, and stable discharges, and has guaranteed antibiotic activity.
The specific embodiment
Embodiment:
(1) sisal fiber that 0.5g is sheared soaked 2 hours with the vertical knot essence of washing in vain, and then hand rubbing is extremely clean a little, again with the distilled water washing, to remove the impurity dry for standby on sisal hemp surface;
(2) it is in 2% the sodium hydroxide solution 8 hours that the sisal fiber that step (1) is made is soaked in weight fraction, and then washing is to neutral, to remove the lignin in the sisal fiber, the pectin dry for standby;
(3) sisal fiber that step (2) is made places apparatus,Soxhlet's to extract 24 hours, and extract is 1: 1 absolute ethyl alcohol of volume ratio and the mixed liquor of analyzing pure cyclohexane, to remove the pectin in the sisal fiber, dry for standby;
(4) it is the 10mmol/L liquor argenti nitratis ophthalmicus that the sisal fiber that step (3) is made is put into the 40mL molar concentration, being placed on wavelength is 253.9nm, power is 60min under the uviol lamp of 20W, then sisal fiber is used the distilled water washes clean, placed 50 ℃ of thermostatic drying chamber inner dryings can make antibacterial sisal fiber.
