摘要: 采用纤维膨化、浸酸、碱煮及柔化整理工艺对竹原纤维进行化学脱胶处理,并对浸酸和碱煮工艺中溶液浓度、处理温度、时间和浴比进行优化设计,提取出可适用于非织造或复合材料工业的纺织纤维。对处理前后纤维的纵向结构进行扫描电镜分析,并对纤维的拉伸断裂强度进行测试与评价,确定出最佳处理工艺。结果表明:酸碱处理过程中溶液的质量浓度对纤维的拉伸性能影响最大,当酸碱质量浓度分别为1.58、g/L时,竹原纤维的拉伸强度可达到5.5 cN/dtex,比处理前提高了近27倍,且柔软度提高1倍,可被梳理成均匀的纤维网。

Abstract: Raw bamboo fibers used for non-woven and composite industries were prepared by means of swelling,acid & alkali treatments and softening treatment,in which,the four parameters of acid & alkali treatments were optimized,namely concentration,temperature,duration of treatment and bath ratio.The longitudinal directions of the fibers were examined by scanning electron microscopy(SEM),and the tensile strength of the fibers were tested and evaluated so as to determine the optimal process.The results reveal that concentration of the acid & alkali treatments has the greatest influence on the tensile property of the fibers.When the acid & alkali concentrations are(1.5 g/L) and(8 g/L) respectively,the tensile strength of the fibers attains a peak at(5.5 cN/dtex,) which is increased by nearly 27 times than that of the fibers before treatment,and the softness increases by one time.Therefore,the fibers can be carded into uniform fiber webs.
