Structure and properties of antibacterial multifunctional polyamide fibers

The melt spinning is conducted with the material mixed with antibacterial multifunctional powders so that the spun fibers have high antibacterial,far-infrared emission and negative oxygen ions release functions.An investigation into the structure and multi-functional properties of this melt spun polyamide fibers using scanning electron microscopy,spectrum test,X-ray diffraction,thermal analysis and infrared spectroscopy indicates that the addition of the antibacterial multifunctional powers has a certain affect on the polyamide fibers.Functional testing results show that the antibacterial multifunctional polyamide fibers have excellent antibacterial effect,and at the same time they exhibit rather good far-infrared emission and negative oxygen ion release functions.When added proportion of the powders is 2.0%,the polyamide fibers have stable structure and good multi-functionalities.
