摘要
对皮芯型复合纤维的细度不匀率的测试方法进行研究和探讨。皮芯型复合纤维由于其皮层包覆芯层的结构,无法用传统的测试方法评价细度不匀率。于是,对细度不匀率的表征转换为对横截面积不匀率的表征。采用万能显微镜采集横截面图像,并分别测量皮芯型复合纤维的芯层截面面积与总的横截面面积,计算芯层面积不匀率和总面积不匀率。
The method of measuring the fine unevenness of composite fibers in skin-core structure was studied. With the core coated by the sheath, the fine unevenness of the composite fibers in skin-core structure can not be measured by traditional methods. Therefore, a new method is proposed to express the unevenness by measuring the area irregularity instead of the fine unevenness, collecting a group of images of cross section using the universal tool-measuring microscope and measuring the area of the core and the total area of the fiber respectively.
