Abstract
The present invention relates to a kind of antibacterial masks, fiber can be made to be provided with good bacteriostatic activity wherein antibacterial peptide is utilized, bacteriostasis rate up to 99% or more, and prepare it is simple, it is low in cost, can large-scale promotion for antibiotic fabric production.
Description
Technical field
The present invention relates to a kind of masks, more particularly to a kind of improved mask for improving bacteriostasis rate.
Background technique
Necessity when mask is doctor, nurse job, with the development of industry, the pollution of air are also more tighter than in the past
Weight, therefore mask can prevent the invasion of bacterium and dust to human body at the articles for daily use in for people's lives.Common mask
Only has general filtering function, function is relatively simple.Respiration keeps mask cover moist in use simultaneously, thus
Conducive to the growth of bacterial micro-organism.Mask in use, directly contacts mouth, nose and the skin of face of user, if protected
It deposits improper or is used for multiple times and does not clean in time, it will the propagation for causing bacterium endangers the health of user.
In addition, influence of the present PM2.5 particle to ambient air quality and human health is very big, common people's counterpart
Cover shows high enthusiasm, but the mask protected currently on the market particular for this fine particle and few, city
The existing mask overwhelming majority is prepared using non-woven fabrics, gauze, plastic net cloth etc. on field.Theirs knits hole or mesh all
Larger, the effect is unsatisfactory in terms of preventing PM2.5 from entering respiratory tract.
A kind of antibacterial and bacteriostatic type mask is disclosed in CN203789201U, including the oral area and nose for covering wearer
Mask body, mask body be provided with five-layer structure formed layered laminate, be successively from outside to inside outer layer PP non-woven fabrics, sizing
Cloth, PM2.5 particle filtering cloth, internal layer SMS non-woven fabrics and chitosan non-woven cloth, are cut into the shape of mask body, edge
Heat pressure adhesive is carried out using hot melt adhesive；Outer layer PP non-woven fabrics uses the cloth of 10-15g/m2, and setting cloth is using 12-16g/m2's
Cloth, PM2.5 particle filtering cloth use the super fine denier electret meltblown fibers non-woven cloth of 10-12g/m2, internal layer SMS non-woven fabrics
Using the cloth of 10-15g/m2, chitosan non-woven cloth uses the cloth of 15-20g/m2.But the mask is using five layers
Special layer structure, complex manufacturing technology, although can filtration fraction PM2.5 particle, in the effect of antibacterial and bacteriostatic also
Have much room for improvement and reinforces.
A kind of carbon fiber ultrafiltration antibacterial mask, the mask sheet of carbon fiber ultrafiltration antibacterial mask are disclosed in CN204034074U
Body is made of internal layer, antibacterial ultrafiltration layer, filter layer and outer layer.Outer layer can stop larger pollution particle in environment；Filter layer energy
It enough filters in environment and largely pollutes particle；The antibacterial layer of ultrafiltration can poisonous and harmful substance in filtered atmospheric, but the antibacterial layer
Effect is not significant in the growth for inhibiting bacterium, and the selection of the material is needed to pay significant effort.
The manufacturing method about antibacterial and antimycotic wet tissue is disclosed in CN101960070A, is by wet tissue processed with whole
Block fabric (such as non-woven fabrics, cotton, paper) is soaked in wet tissue manufacture together with nano metal particles and is manufactured in water, and wet tissue manufacture is used
Water contains the metallic particles of the nano-scale size with antibacterial and anti-fungus function, and the wet tissue of manufacture has multiple antibacterial and resists true
Bacterium and other effects.But the program needs to be easy to cause the wasting of resources, and after testing using metallic particles, antibacterial efficiency is also
Need further to be enhanced.
The defect of the comprehensive prior art, is designed a kind of with the antibacterial having clear improvement than the prior art, bacteria resistance function
Mask be a technical problem to be solved urgently.
Summary of the invention
The technical problem to be solved in the present invention is that for mask in the prior art in preparation method complexity, material cost
The defect of high and antibacterial low efficiency, provide it is a kind of have while cost is relatively low, ultimate strength is able to satisfy application requirement it is relatively strong
Mask of antibacterial ability and preparation method thereof.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of mask with good antibiotic property is provided, is fine using epsilon-polylysine polyvinyl alcohol biological composite antibacterial
What dimension was prepared.
The present invention additionally provides a kind of epsilon-polylysine polyvinyl alcohol biological composite antibacterial fiber with good antibiotic property
Preparation method, the present invention keeps epsilon-polylysine polyvinyl alcohol biological by the method for addition biological preservative epsilon-polylysine
The bacteriostasis rate of composite antibacterial fibre is improved.
The present invention realizes that the technical solution of purpose is: using water-DMSO system when preparation, the volume ratio of water and DMSO are 6:
4-2:8 adds the NaCl of 1-3% in mixed liquor, and epsilon-polylysine is added in uniformly mixed spin solvent, and stirring makes ε-is poly- to rely
Propylhomoserin is completely dissolved.The PVA (degree of polymerization 1750 ± 50) of 8-20% is weighed, is added in spinning solution at room temperature, stirring is allowed to fill
Tap contacts solvent, is standing and soaking 30-60min after stopping stirring, then places it in water-bath and heated, is gradually warming up to
60-70 DEG C, 1-2h is kept, then heating to 95-100 DEG C is completely dissolved PVA, and dissolution, which finishes, to be kept the temperature 2-3h again and can be sprayed
- 20 DEG C of use of anhydrous methanol is bathed in silk, condensation, and anti-bacterial fibre in condensation bath is taken out drying at room temperature by condensation time 10-60s
Obtain spun.Spun can become the anti-bacterial fibre product that diameter is 0.005-0.1mm by stretching.
The present invention additionally provides a kind of antibacterial peptide, the peptide be applicant's early period by screening, identification obtain have compared with
The polypeptide of the inhibition microorganism of good spectrum, the sequence such as SEQ ID NO:1-5 are any shown.
A kind of addition antibacterial peptide and epsilon-polylysine polyvinyl alcohol biological composite antibacterial fiber with good antibiotic property
Preparation method, use water-DMSO system when preparation, the volume ratio of water and DMSO are 6:4-2:8, add 1-3% in mixed liquor
NaCl, epsilon-polylysine is added in uniformly mixed spin solvent, stirring is completely dissolved epsilon-polylysine.Weigh 8-20%
PVA (degree of polymerization 1750 ± 50), be added in spinning solution at room temperature, stirring is allowed to be adequately exposed to solvent, after stopping stirring
It is standing and soaking 30-60min, then places it in water-bath and is heated, is gradually warming up to 60-70 DEG C, 1-2h is kept, then rises
Temperature is completely dissolved PVA to 95-100 DEG C, and dissolution finishes keeps the temperature 2-3h again, and antibacterial peptide additional amount is then added and stirs for 100mg/L
It mixes uniformly, spinneret can be carried out, -20 DEG C of use of anhydrous methanol, condensation time 10-60s, by anti-bacterial fibre in condensation bath are bathed in condensation
Taking out drying at room temperature can be obtained spun.Spun can become the anti-bacterial fibre production that diameter is 0.005-0.1mm by stretching
Product.
A kind of mask with good antibiotic property is provided, is poly- using above-mentioned addition antibacterial peptide and epsilon-polylysine
Vinyl alcohol biological composite antibacterial fiber is prepared.
The advantages and positive effects of the present invention are: the present invention is poly- by adding biological preservative ε-in fiber manufacturing process
Lysine and antibacterial peptide, are capable of the microorganism of the inhibition external source of broad spectrum activity, and the control group of less addition epsilon-polylysine is antibacterial
Rate significantly improves, and present invention preparation is simple, can large-scale promotion application, there is high application value.
