[0002] The measurement of textile fiber diameter is of paramount importance for ensuring textile performance, optimizing production processes, controlling product quality, and enhancing market competitiveness. It is crucial throughout the entire production chain and product lifecycle, from raw materials to finished products. A commonly used and cost-effective method for measuring fiber diameter is microscopy. This involves preparing temporary or permanent sections of the fiber and observing them under an optical microscope. The fiber diameter is then measured using an eyepiece micrometer or image analysis software. The eyepiece micrometer is a graduated glass slide mounted in the eyepiece, allowing the calculation of the actual fiber diameter based on the known graduations and the microscope's magnification.
