静电纺锦纶6纳米级纤维的形态结构

 采用静电纺丝的方法纺制了锦纶6纳米级纤维,分析了锦纶6甲酸溶液质量分数、喷丝头与接收屏之间的距离(C-SD)和电压对纤维形态结构的影响,讨论了上述参数和静电纺锦纶6纤维直径分布之间的关系。结果表明,静电纺锦纶6纤维的直径随着纺丝液质量分数的增加而增加,锦纶6甲酸溶液在质量分数为12%左右时的静电纺丝效果最好;当电压超过15 kV时,纤维的直径随着电压的增加而减小,而且直径的分布趋于集中;C-SD对纤维直径的影响呈现波动性特征。

Configuration of electrospun polycaprolactam nano-scale fibers

Nano-scale polycaprolactam fibers were electro-spun.The effect of voltage,distance from spinneret to collecting screen(C-SD) and concentration of polycaprolactam-formic acid solution on the configuration of the fiber was analyzed,and the relationship between the above electro-spinning parameters and the diameter distribution of the spun fiber was investigated.The results indicated that the diameter of electro-spun nylon fiber increases with the increase of the solution concentration,and the best spinning result is achieved when the concentration is 12%.When the voltage exceeds 15 kV,the fiber diameter becomes finer with the rising of the voltage,and the diameter distribution of the fiber tends to consistency.The change of C-SD makes the size of electro-spun nylon 6 fiber undulated.
