The effect of extraction time, temperature, and alkali concentration on the physical and mechanical properties of cattail ( L.) fibres were investigated using five levels of time (4, 6, 8, 10, and 12 h), four levels of temperature (70, 80, 90, and 95 °C), and three levels of NaOH concentration (4, 7, 10%, /) in a 3 × 4 × 5 factorial experimental design. The extraction parameters were optimized for bio-composite application using a desirability function analysis (DFA), which determined that the optimum extraction time, temperature and NaOH concentration were 10 h, 90 °C, and 7%, respectively. A sensitivity analysis for optimal treatment conditions confirmed that the higher overall desirability does not necessarily mean a better solution. However, the analysis showed that the majority of optimum settings for time, temperature, and concentration of NaOH found in the sensitivity analysis matched with the optimum conditions determined by DFA, which confirmed the validity of the optimum treatment conditions.
采用3×4×5析因试验设计,研究了提取时间、温度和碱浓度对香蒲纤维物理和力学性能的影响,其中时间设5个水平(4、6、8、10和12小时),温度设4个水平(70、80、90和95℃),氢氧化钠浓度设3个水平(4%、7%、10%,/)。使用期望函数分析(DFA)对生物复合材料应用的提取参数进行了优化,确定最佳提取时间、温度和氢氧化钠浓度分别为10小时、90℃和7%。对最佳处理条件的敏感性分析证实,较高的总体合意性不一定意味着是更好的解决方案。然而,分析表明,敏感性分析中发现的大部分时间、温度和氢氧化钠浓度的最佳设置与DFA确定的最佳条件相匹配,这证实了最佳处理条件的有效性。
