The physico-chemical properties of jute fibers treated with alkali (NaOH) solution have been investigated in this study. The treatments were applied under ambient and elevated temperatures and high pressure steaming conditions. To the knowledge of these authors the influence of alkali-steam treatment on the uniaxial tensile strength of natural ligno-cellulosic fibers, such as jute, has not been investigated earlier. The results from this investigation indicate that a 30 min dipping of the fibers in 0.5% alkali solution followed by 30 min alkali-steam treatment leads to an increase in the tensile strength of up to 65%. The increase appears to be due to fiber separation and removal of non-cellulosic materials, which, in turn, resulted in an increased crystallinity.
本研究探讨了经氢氧化钠（NaOH）溶液处理后的黄麻纤维的物理化学性质。这些处理是在环境温度和升高的温度以及高压蒸汽条件下进行的。据作者所知，以前没有研究过碱-蒸汽处理对天然木质纤维素纤维（如黄麻）的单轴拉伸强度的影响。这项研究的结果表明，将纤维在 0.5%的碱溶液中浸泡 30 分钟，然后再进行 30 分钟的碱-蒸汽处理，可使拉伸强度提高高达 65%。这种增加似乎是由于纤维分离和非纤维素材料的去除，这反过来又导致结晶度增加。
