Antimicrobial Natural Cellulose Fibers from Hyptis suaveolens for Potential Biomedical and Textiles Applications

ABSTRACT

In this research, tulsi (wild type) stalks were treated with NaOH to obtain natural cellulosic fibers. X-ray diffractions showed typical cellulose diffraction peak at 22.7°. The fibers had a tensile strength of 445 MPa, higher than fibers obtained from other agricultural residues. The fibers also displayed good thermal stability up to 300℃ making it suitable for a wide range of applications. The fibers inherited the antimicrobial properties from the stalks and showed high activities against both Gram positive and Gram negative bacteria. The extracted fibers could be used in composites and manufacturing tents and canvas.

摘要

本研究采用氢氧化钠处理郁金香茎，获得天然纤维素纤维。X射线衍射显示，典型的纤维素衍射峰为22.7 ^o，纤维的拉伸强度为445Mpa，高于其他农业残留物的纤维. 纤维还显示出良好的热稳定性高达300℃使其适用于广泛的应用. 纤维继承了茎杆的抗菌特性，对革兰氏阳性菌和阴性菌均有很高的抗菌活性. 提取的纤维可用于复合材料、帐篷和帆布的生产.
