Abstract

This invention relates to a measurement method and a system for diameters of non-woven fabric diameter of a polymer extrusion including: first of all sampling fibers, then collecting fiber images, processing the fiber image, testing the diameter of the fiber and making statistics. The system includes: a microscope, a light source, a CCD camera, interface accessories, an image collecting card and a computer, which can accurately and effectively test the mean value, the standard difference, aberrance coefficient and diameter distribution of the diameter of polymer extrusion method non-woven fabric cloth fibers.

Description

technical field [0001] The invention belongs to the field of textiles, and relates to a method and system for measuring the fiber diameter of polymer extrusion nonwoven fabrics. Background technique [0002] According to the processing method, nonwovens can be divided into dry method, wet method and polymer extrusion method. Among them, the polymer extrusion method is a kind of nonwoven fabric processing method with the fastest development speed and the most development potential. Polymer extrusion methods mainly include spunbond method and meltblown method. Fiber diameter is one of the most important parameters to measure the quality of polymer extrusion nonwovens, and it has attracted much attention in the textile industry. [0003] At present, the commonly used fiber fineness measurement methods include weighing method, airflow meter method, microprojector method and vibration method. These methods are applicable when the fibers to be tested are in the state of individ...
