Embodiment 1

[0024] Please refer to Fig. 1, which is a schematic structural diagram of the system of the present invention. The system of the present invention utilizes the random number generator program compiled by the present invention to realize random sampling of nonwoven fabrics, utilizes CCD camera 3 and microscope 1 to collect nonwoven fabric images, utilizes image acquisition card 5 to convert nonwoven fabric images into digital images and input them into the computer In 6, image processing and porosity measurement are performed using the software designed by this system.

[0025] 1. Hardware composition

[0026] As can be seen from Figure 1, the system hardware mainly includes microscope 1, light source 2, CCD camera 3, interface accessories 4, image acquisition card 5, computer 6 and so on. Microscope 1 uses transmitted light as the light source, and light source 2 uses light-emitting diodes. The spectral characteristics of the microscope light source will affect the microscop...

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a method and system for measuring the porosity of nonwoven fabrics. Background technique [0002] With its unique processing methods and structural properties, nonwovens are playing an important role in all aspects of production and life. In the fields of medical and health, civil engineering, environmental protection, agriculture, etc., porosity is one of the most important parameters to measure the quality of nonwovens, and has attracted extensive attention. Generally, the larger the porosity, the larger the pore volume inside the nonwoven fabric, and the better the permeability. At present, there is no special method and system for measuring the porosity of nonwoven fabrics. People often use the porosity measurement methods of woven fabrics or porous materials to measure the porosity of nonwoven fabrics. Analyzer method and scanning method, etc. The weighing method is to...
