Description
Technical field
The present invention relates to anti-biotic material field, be specially a kind of alloy antibacterial matrices and application in the yarn thereof.
Background technology
At present, infectious diseases occupies the second of global Death causes.Along with the appearance of new microbe and new infeetioa disease, population growth and crowded, herd immunity constantly declines, and antibiotic resistance constantly increases, and infectious diseases will strengthen the impact on the whole world.Whole world infectious diseases become dead head because of.
Only experience over half a century, antimicrobial drug can be killed germy present situation and be gone for ever, and new resistant organism instead of old sensitive organism, and global drug resistance problems is quite serious, particularly outstanding in the country of resource-constrained.Methicillin-resistant staphylococcus aureus (MRSA); vancomycin-resistant enterococcus (VRE); Multi-resistant Gram-negative bacilli; the rapid growth of the candidiasis of resistance to fluconazole etc. and propagation; make the crisis that facing mankind is unprecedented; other resistant organisms, as multidrug resistant bacteriums such as streptococcus pneumoniae, gonococcus, salmonella, all need tightly monitor.Community-acquired resistant organism and Nosocomial resistant organism have common epidemiologic feature: incorrect prescribing behaviour, and population mobility increases, and resistant organism, in crowded place, is propagated by people-people's approach.The storage bacterium institute that hospital or community's pathogenic bacteria of drug-resistant are propagated.Although the expense per capita of developing country's antimicrobial drug is lower, in total medical expense, 35% is all for antimicrobial drug, and developed country is only 11%.The phenomenon of developing country's abuse antimicrobial drug is very general.By monitoring, the medicine that the most frequently used Ampicillin Trihydrate, multiple square Sulfamethoxazole, tsiklomitsin etc. are inexpensive, finds that its resistant rate is higher than the report of developed country a lot.Cause respiratory tract infection and meningitic pathogenic bacteria, if the resistance of streptococcus pneumoniae, hemophilus influenzae, moraxelle catarrhalis, Neisseria meningitidis, mycobacterium tuberculosis is also in swift and violent increase.Resistant organism is also very common in enteron aisle and sexually transmitted disease (STD), this is because abuse antimicrobial drug causes powerful selection pressure, cause appearance and the propagation of multi-drug resistant bacteria, so must strictly control antibiotic use, use in-vitro antibacterial material as far as possible, pathogenic bacterium threat intercepted in vitro, this is also the effective ways stoping resistant organism big area to occur.
And existing antibiotic fabric is mainly with antibacterial raw material plated film on fabric, there is not wash resistant in coating process, Reusability anti-microbial property decline defect, therefore be badly in need of a kind of can with the antibacterial raw material of fabric mortise to solve the problem.
Application number is 201110401227.3, and publication number is that a kind of high-efficiency environment friendly antibacterial mould-proof inorganic composite nano of Chinese patent powder slurry of CN102511503A and preparation method thereof discloses the environment-friendly antibacterial mildew-resistant inorganic composite nano powder slurry formed with other auxiliary agent with nano cuprous oxide, nano zine oxide, polyacrylic (or polyacrylate).Employ nano-zinc sulfide in concrete technical scheme, zinc sulphide easily causes degraded to plastics when high temperature, can make viscosity and spout viscosity in stove that serious change occurs, and making cannot stably output yarn; The yarn loss made of this formula is in addition large, easy fracture.
Therefore be badly in need of at present one there is good antibacterial effect, loss is little, and concrete elastic yarn and be applied to the antibacterial matrices of preparation this kind of yarn.
Summary of the invention
