When characterizing the microstructure of fibers, preparing fiber multifilament samples is an important task. However, due to the extremely small size of the fiber multifilament surface and cross-section micro-morphology samples, the preparation of fiber multifilament microstructure samples faces many challenges: complicated steps, time-consuming, requires rich experience, and often difficult to accurately obtain the surface and cross-section of the fiber multifilament. Therefore, developing a sample preparation device and method that can quickly obtain the surface and cross-section micro-morphology samples of the multifilament has become a key problem for technical personnel in the field.

Therefore, there is an urgent need for a sample preparation device that is easy to operate and can quickly and efficiently prepare fiber multifilament surface and cross-section micro-morphology samples.
