Dralon细旦异形腈纶纤维的形态结构及性能研究

为了了解Dralon细旦异形腈纶纤维的性能,对所选的Dralon细旦异形腈纶纤维、有光棉型普通腈纶纤维、棉型蓄热散热竹炭腈纶纤维的强伸性能、摩擦性能和吸湿性能进行测试和分析,并用扫描电子显微镜观察三种纤维横截面和纵向形态。结果表明:Dralon细旦腈纶纤维具有哑铃型异形截面;与普通腈纶和竹炭腈纶相比,其强度高、摩擦系数大、吸湿性好。

Research on morphology structure and properties of Dralon fine denier profiled acrylic fiber

In order to understand the properties of Dralon fine denier profiled acrylic fiber,the tensile properties,friction properties and hygroscopicity of Dralon fine-denier profiled acrylic fiber,luster cotton-spun acrylic fiber and cotton-type regenerative heat bamboo charcoal acrylic fiber are tested.The cross-sectional and longitudinal morphology of the three kinds of fibers are observed with scanning electron microscope.The results show that Dralon fine denier profiled acrylic fiber has a dumbbell-shaped cross-section,and its tensile strength is higher,its friction coefficients are larger and its moisture absorption property is better than the other two acrylic fibers.
