Enterobacteria 8099, Candida albicans ATCC 10231, sample sterilization method are the 15min that sterilizes at 121 DEG C of high steam, calculate suppression
Bacterium rate formula are as follows: Y=(WT- QT)/WT× 100%, wherein Y is the bacteriostasis rate of sample, WTAfter control sample 18h concussion contact
The average value of viable bacteria concentration, Q in flaskTFor the average value of viable bacteria concentration in flask after test sample 18h concussion contact.
Test result shows the polyester fiber of the present embodiment to staphylococcus aureus, Escherichia coli and Candida albicans
Bacteriostasis rate reach 99%, standard provides bacteriostasis rate >=70% to staphylococcus aureus and Escherichia coli, or to white
When the bacteriostasis rate of candida albicans >=60%, sample has antibacterial effect, from test result it can be concluded that, the polyester in the present embodiment
Fiber has good fungistatic effect;
Measure the performance of polyester fiber in the present embodiment:
Wherein, filament number 1.8dtex, breaking strength 4.3CN/dtex, elongation at break 45%, resistivity reaches
To 108 Ω .cm.
The foregoing is merely preferred modes of the invention, are not intended to limit the invention, all in spirit and original of the invention
Within then, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
