采用正交试验对竹原纤维进行碱处理,研究碱液浓度、温度和处理时间对其力学性能的影响;同时采用电子显微镜观察碱处理前后竹原纤维纵、横向微观结构.结果表明,碱液温度对竹原纤维强度性能影响较大,碱液浓度对纤维细度和伸长率的影响较大;竹原纤维碱处理最佳工艺条件为:碱液温度20℃,质量浓度7.5g/L ,处理时间90min ,此时纤维强度稍有下降,伸长率和细度不匀率明显改善,提升了竹原纤维可纺性.
採用正交試驗對竹原纖維進行堿處理,研究堿液濃度、溫度和處理時間對其力學性能的影響;同時採用電子顯微鏡觀察堿處理前後竹原纖維縱、橫嚮微觀結構.結果錶明,堿液溫度對竹原纖維彊度性能影響較大,堿液濃度對纖維細度和伸長率的影響較大;竹原纖維堿處理最佳工藝條件為:堿液溫度20℃,質量濃度7.5g/L ,處理時間90min ,此時纖維彊度稍有下降,伸長率和細度不勻率明顯改善,提升瞭竹原纖維可紡性.

The natural bamboo fiber was modified by orthogonal experiment ,the effect of concentrations of alkali ,temperature and time on the mechanical properties of nature bamboo fiber after alkali treatment is studied .Meanwhile ,bamboo fiber′s longitudinal and transverse microstructure are observed by elec-tron microscopy .The results show that the intensity of nature bamboo fibers were greatly affected by temperature ,w hile the fineness and the elongation of fiber is greatly affected by concentrations of alkali . T he best process of alkali treatment is as follow s :the concentrations of alkali is 7.5g/L ,the temperature of liquid is 20℃ ,and keep the treatment for 90mins ,then the intensity of nature bamboo fiber declined slightly ,the elongation and fineness of irregularity obviously improved ,therefore the spinnability of na-ture bamboo fiber can be improved as well .
