Abstract

The effect of surface modification on the mechanical properties and water absorption of Raphia farinifera (raphia fibre) were examined. The fibre was treated with 2% benzoyl peroxide in acetone, 10% potassium hydroxide, 25% hydrogen peroxide and 1% potassium permanganate in one hour. The mechanical properties; tensile strength, load at break, modulus and water absorption properties were investigated and results compared with control (untreated fibre). The results of the mechanical properties showed that the tensile strength of the fibre (Raphia farinifera) improved from 50.1142MPa for the untreated fibre to 132.3482MPa for potassium hydroxide treatment and 146.0181MPa for hydrogen peroxide treatment. Benzoyl peroxide treatment showed superior load at break value (25.5617N) over the untreated fibre (14.7847N). The results of water absorption showed that the treatment of the fibre reduced the hydrophilic nature of this fibre. However, benzoyl peroxide treatment showed highest reduction in water absorption capacity of the fibre followed by potassium hydroxide treatment.

表面改性对拉斐亚纤维(Raphia farinifera)机械性能和吸水性的影响
研究了表面改性对鸦胆子纤维(Raphia farinifera)机械性能和吸水性的影响。用 2% 丙酮过氧化苯甲酰、10% 氢氧化钾、25% 过氧化氢和 1% 高锰酸钾在一小时内对纤维进行处理。研究了纤维的机械性能、拉伸强度、断裂负荷、模量和吸水性能,并将结果与对照组(未处理纤维)进行了比较。机械性能结果显示,纤维(Raphia farinifera)的拉伸强度从未经处理的 50.1142 兆帕提高到氢氧化钾处理的 132.3482 兆帕和过氧化氢处理的 146.0181 兆帕。过氧化苯甲酰处理纤维的断裂载荷值(25.5617N)优于未处理纤维(14.7847N)。吸水率结果表明,纤维的处理降低了其亲水性。不过,过氧化苯甲酰处理对纤维吸水能力的降低幅度最大,其次是氢氧化钾处理。
