Description
Technical field
The invention belongs to non-woven material fields, and in particular to a kind of nanofiber antibacterial nonwoven material and preparation side
Method.
Background technique
Non-woven material is also known as non-woven cloth, nonwoven fabric, supatex fabric, adhesive-bonded fabric or non-woven fabrics.Nonwoven techniques
It is one derived from weaving, but surmounts the materials processing technology of weaving.It is big soft that it combines weaving, papermaking, leather and plastics four
Property materials processing technology, and many modern high technologies are sufficiently combined and have used, such as computer control, information technology, high pressure
Jet stream, plasma, infrared, laser technology etc..No matter in space technology, environment protection treating, agricultural technology, health-care medical or people
Many fields such as daily life, non-woven new material has become a kind of more and more extensive staple product.With scientific skill
The development and the improvement of people's living standards of art, people's health consciousness constantly enhancing, carry out antibacterial, antibacterial to non-woven material
Property processing or processing, can be effectively reduced or avoid influence of the bacterium to health.Produce have antibacterial, biocidal property it is non-
Weaving material product is carried out generally by the method for adding antibacterial agent bacteriostatic agent or final finishing in spinning solution.But
It is easy to be uneven with mixed with polymers that antibacterial agent is added in spinning solution, is easy blocking spinneret, not can guarantee continuous production, it is rear whole
The complex process of reason method, higher cost, and the anti-microbial property for the non-woven material being prepared into is to be improved.
Summary of the invention
In view of the deficiencies of the prior art, one of the objects of the present invention is to provide a kind of nanofiber antibacterial nonwoven materials
Material, excellent antibacterial performance.
To achieve this purpose, the present invention adopts the following technical scheme:
A kind of nanofiber antibacterial nonwoven material, including at least two layers of nanofiber antibiotic layer are received described in adjacent two layers
Nanofiber hydrophilic layer is provided between rice fibre antibacterial layer, the nanofiber of the nanofiber antibiotic layer is handed in three-dimensional space
Fork arrangement, forms the hole with nanoparticle, nanofiber cluster, be distributed in described hole nanometer silver antimicrobial particle and
Nano zine oxide antibacterial granule.
Nano zine oxide has the antibiotic property of relatively strong antibacterial, bactericidal effect and its wide spectrum, and due to quantum effect, small size
Effect and there is large specific surface area, thus the antibacterial effect for having traditional inorganic antiseptic incomparable, become has development very much
The anti-biotic material of new generation of prospect.Zinc oxide is a kind of broad stopband II, and VI group iii v compound semiconductor material has regular hexagonal
Shape wurtzite structure, as white, stability is good for this, non-discolouring under high temperature, do not decompose, is cheap, is resourceful.Nanowire
Nano zine oxide antibacterial granule in dimension antibiotic layer can be decomposited voluntarily after ultraviolet light irradiates moves freely negatively charged electricity
Sub and positively charged hole, this process easily occur.Positively charged hole can aoxidize the generation of the water in non-woven material
Hydroxy radical, while electronics makes the Viability oxygen atom of the hydrogen reduction in air, hydroxy radical and active oxygen atom energy and bacterium
Intracorporal organic matter or unsaturated bond react, and decompose the constituent of microorganism, play antibacterial action.Meanwhile nano oxygen
Change zinc antibacterial granule slow release zinc ion in water-bearing media, in conjunction with bacterial micro-organism protein, and destroys bacterium electronics
The enzyme of transmitting is reacted with-SH group, achievees the effect that double sterilization.Nano zine oxide antibacterial granule also has certain anti-spoke
It penetrates, is crease-resistant, antistatic property.One-dimensional zinc oxide nanometer material refers to nano-scale lower than 100nm and there is bidimensional in space to receive
The ZnO nano material of metrical scale, including nanometer rods, nano wire, nanotube, nano particle etc..Recently as nanotechnology
Development, one dimension semiconductor material such as nano wire, nanometer rods, nano-rings etc. due to its unique physics, chemistry and biological nature and
