摘要
探讨竹炭微粉加入量对改性竹浆纤维成纤结构及性能的影响。采用N-甲基吗啉-N-氧化物水溶液纺丝工艺,制备竹浆纤维和竹炭含量分别为9%、23%、33%的改性竹浆纤维,测试了各纤维的截面形态、直径、断裂强力和断裂伸长率,采用Weibull分布模型对纤维性能指标的离散程度进行统计学描述。试验表明:随着竹炭含量的增加,纤维直径分布模型与Weibull分布模型的一致性降低,而其断裂强力、断裂伸长率分布模型与Weibull(3P)分布模型的一致性升高。认为:竹浆粕中加入竹炭粉的含量在不超过10%的情况下,纺丝过程难度小,改性竹浆纤维的各项性能亦得到明显改善。
The influences of bamboo charcoal micro powder adding content on the fiber structure and properties of modified bamboo fiber were discussed.The spinning process with N-methylmorpholine-N-oxide water solution was adopted.Bamboo fiber and modified bamboo fibers with bamboo charcoal content of 9%,23%and 33%were produced.The cross-section morphology,diameter,breaking strength and breaking elongation of each fiber were tested.The dispersion degrees of fiber property indexes were described with statistics by using Weibull distribution model.The experiments showed that the consistency of fiber diameter distribution model with Weibull distribution model was decreased as the increase of bamboo charcoal content,while the consistency between the breaking strength and breaking elongation distribution models with Weibull(3P)distribution model was increased.It is considered that the spinning difficulties is lower when the content of bamboo charcoal powder is less than 10%.Each property of modified bamboo fiber can be obviously improved.
