Abstract: | In this paper, the mulberry fibers were successfully obtained by a new pretreatment named alkali-assisted microwave plus biological
enzymatic technique (AMBET). The morphology, microstructure, physico-mechanical and antibacterial properties of the mulberry
bast fibers were investigated by means of scanning electron microscope (SEM), Fourier Transform-Infrared (FTIR), differential
scanning calorimetry (DSC), thermogravimetric analysis (TGA), X-ray diffraction (XRD), instron tensile tester and antibacterial
testing. The results showed that impurities of the bast fibers could be removed by AMBET treatment. AMBET treated mulberry
fiber was even, smooth and fine, and typical cellulose I in the mulberry fibers was confirmed by FTIR and XRD analysis. The
crystallinity of the AMBET treated fibers was higher than that of the raw mulberry and chemical treated mulberry fibers. Thermal
analysis indicated that the mulberry fibers had a good thermal stability. Moreover, the AMBET treated mulberry fibers showed
excellent antimicrobial activities against S.aureus. The physical properties of the mulberry fibers indicated the AMBET treated mulberry fibers were ideal candidates for new
textile materials. |
