为了提高洋麻纤维的可纺性，采用碱氧-浴一步柔软方法对洋麻进行精细化处理.利用多指标正交实验方法对总碱浓度、先加入碱浓度、双氧水浓度及碱煮时间这4个参数进行工艺优化设计，通过对纤维细度、断裂强度、柔软度3个指标的综合分析评定最佳处理工艺，并对处理后的洋麻纤维进行基本性能及扫描电子显微镜、傅里叶红外光谱测试.结果表明：最佳处理工艺是总碱质量分数为10%、先加入的碱质量分数为1.2%、双氧水质量分数为1.2%、处理时间为2.5 h；精细化处理的洋麻纤维细度、柔软度、断裂强度分别为13.83 dtex、33.75 r/10 cm、4.13 cN/dtex，与未处理纤维相比，分别降低66.1%、提高25.1%、提高25.9%；扫描电子显微镜及傅里叶红外光谱表明纤维杂质减少，表面粗糙度增加，可纺性提高.

In order to improve the spinnability of the kenaf fibres, alkali oxygen-soft bath step method was used in refinement process for kenaf. Four parameters, such as alkali treatment time, concentrations of pre-alkalithe, alkali and hydrogen peroxide were optimized by multiple indicator orthogonal experimental method based on the evaluation factors of fiber fineness, breaking strength and softness. The basic physical properties, SEM, FTIR of treated kenaf fiber were tested. The results showed that the optimal parameters were alkali concentration of 10%, pre-alkalithe concentration of 1.2%, hydrogen peroxide concentration of 1.2%, and treatment time of 2.5 h. The refinement fineness, softness, and breaking strength of Kenaf fiber are 13.83 dtex, 33.75 r/10 cm, 4.13 cN/dtex respectively, compared with those of untreated fibers, that reduced by 66.1%, improved by 25.1%, improved by 25.9%!respectively. SEM and FTIR show that the fine treatment fibers have low surface impurities, high surface roughness and soimproved spinnability.
