Abstract
The invention discloses a novel antibacterial alginate fiber and a preparation method thereof. The preparation method is characterized by including: adding alginic acid and a certain amount of compound ammonium salt into a reaction kettle for reaction to prepare ammonium alginate; dissolving ammonium alginate in water to prepare a spinning stock solution of 3-8% in mass percentage; in an ammonia water coagulating bath containing ammonium chloride and basic cupric carbonate, adopting a wet spinning process to obtain the antibacterial copper ammonium alginate fiber. The copper ammonium alginate fiber obtained is soft in texture, high in hygroscopicity, antistatic, safe to human body and free of toxic and side effect and has a lasting antibacterial function; the novel antibacterial alginate fiber can be used for manufacturing medical nonwoven cloth and can be blended with cotton ramie, mucilage glue, bamboo fiber, natural silk and tencel silk to manufacture high-end clothes and facial mask base cloth.
Description
Technical field
The present invention relates to can be used for making textile and the novel antibacterial alginate fibre of mask substrate,
A kind of novel antibacterial alginate fibre and preparation technology thereof.
Background technology
Improving constantly the continuous renewal with consumption idea along with scientific and technological level, the people increasingly note
The security of fiber used such as weight daily textile especially underwear, mask nonwoven fabric etc., both effectiveness
And the feature of environmental protection.Alginate fibre be use in natural seaweed the material spinning processing extracted and
Becoming, because its raw material is from natural seaweed, fiber has good biocompatibility, high-strength suction
Moist and antibiotic property, nontoxic, harmless, security is high and biodegradability, at medicine, ring
All there is good application prospect in the fields such as guarantor.
Summary of the invention
It is an object of the invention to provide the one that can be used for making textile and mask substrate new
The antibacterial alginate fibre of type and preparation technology thereof.It is different from tradition alginate fibre, because it contains copper
Ammonium ion, has higher hygroscopicity, antibiotic property, flexibility and natural color.
To achieve these goals, the technical solution used in the present invention is:
A kind of novel antibacterial alginate fibre and preparation technology thereof, it is characterised in that comprise following step
Rapid:
(1) alginic acid and a certain amount of ammonium salt compound are joined in reactor, react 40-60
Minute, be neutralized to be fully converted to ammonium alginate, wherein, neutralize reaction include solid phase neutralize and
In liquid phase with alcohol as medium and reaction；
(2) ammonium alginate prepared, with ethanol wash 1-3 time；
(3) centrifugal after washing, sliding cylinder extrusion granulation, it is dried, pulverizes the ammonium alginate of system；
(4) it is 3-8%'s that appropriate ammonium alginate is dissolved in deionized water preparation mass percent
Ammonium alginate solution；
(5) appropriate ammonium chloride, basic copper carbonate are dissolved in ammonia spirit and prepare percent mass
Than the cuoxam for 2-6%, as coagulating bath；
(6) by the coagulating bath in step (5) of the ammonium alginate solution in step (4)
Alginic acid cuprammonium rayon is prepared in spinning in a wet process.
Improvement further to technical scheme: in described step (1) ammonium salt compound by ammonium chloride and
Basic ammonium salts forms, ammonium chloride: basic ammonium salts=10-20:80-90；
Improvement further to technical scheme: in described step (1), the consumption of ammonium salt compound is sea
The 8%-20% of alginic acid；
Improvement further to technical scheme: in described step (1) ammonium salt compound include ammonium carbonate,
Ammonium hydrogen carbonate, ammonium acetate one or more；
Improvement further to technical scheme: washing agent alcohol in described step (2), its alcohol
Degree >=40%vol (normal temperature 20 DEG C)；
Improvement further to technical scheme: in described step (6) ammonium alginate solution through filter,
After vacuum deaerator, spinning in a wet process in coagulating bath under the conditions of 10-20 DEG C.
Alginic acid cuprammonium rayon of the present invention, comprises copper ion, ammonium ion in molecular structure,
And copper ion is in the molecule rather than to be adsorbed at fibre by suction-operated by chemical bond linkage
Dimension table face, thus as the copper ion of fibre structure, will not be molten because of contact sweat, faintly acid
Liquid, weakly alkaline solution and the copper ion that dissociates, enter inside of human body and cause heavy metal poisoning, when
When it is as medical accessories, the body fluid that wound oozes out can make marine alga cuprammonium rayon gelatine, the most not
The copper that can cause excess penetrates in blood, and copper is the trace element of needed by human.
Alginic acid cuprammonium rayon of the present invention, because containing copper ion, fiber presents light blue,
Thus can directly draw a design in fabrication processes.
Alginic acid cuprammonium rayon of the present invention, compared to tradition alginate fibre, it has higher
Antibiotic property and biocidal property, because of in molecule containing ammonium ion, its acid resistance is greatly improved, and promotes
Textile recycling rate of waterused prepared by alginate fibre, and there is certain anti-flammability.
Marine alga cuprammonium rayon of the present invention is prepared with natural seaweed composition for raw material, fine
Dimension softness, the skin of more fitting such as the dress ornament made, underwear, mask substrate, there is high-strength suction
Aqueous.Alginate fibre prepared by the method is practically free of sodium ion and calcium ion, the fibre of preparation
Dimension toughness is high.
