Abstract:

In order to prepare functional viscose fiber with antibacterial, anti-mite and anti-mildew functions and durability, the extract solution of traditional Chinese medicine Litsea cubeba and Foeniculum vulgare prepared by water dissolution and the thyme essential oil microcapsule were blended with viscose spinning solution. Then the modified viscose fiber with antibacterial, anti-mite and anti-mildew functions was prepared by wet spinning. The structure and properties of the fiber were characterized by scanning electron microscopy, Fourier infrared spectroscopy, X-ray diffraction, single fiber strength tester and antibacterial, anti-mite and anti-mildew related testing instruments. The results show that compared with the ordinary viscose fiber, the crystal cell structure of the modified viscose fiber is not changed, and the crystallinity and orientation are 41.3% and 77.1%, respectively, which are in accordance with the common viscose fiber. The nonwovens made of the fibers have good anti-bacterial, anti-mite and anti-mildew functions and wash resistance.

Key words: functional fiber, viscose fiber, thyme essential oil, antibacterial property, anti-mite and anti-mildew property, wet spinning
