Abstract

The invention relates to a method for measuring the diffusivity of disposable sanitary products, which mainly solves the problems of low measurement efficiency and poor measurement accuracy of the diffusivity of disposable sanitary products in the prior art. The unit acquires a product image, the product image includes an image of the product image and the diffusion image of the test liquid on the product; 2) binarizes the product image, so that the diffusion image on the product forms spots; 3) extracts spot distribution map data forming a virtual image; 4) comparing the virtual image with a preset size image, the size image is composed of measuring cells with a certain size distributed in a matrix, and by identifying the number of cells covering the spots on the virtual image As well as the position, output the value of the diffusion length, width and diffusion area of ​​the test liquid on the product.

Description

technical field [0001] The invention relates to a method for measuring the diffusivity of disposable sanitary products. Background technique [0002] At present, to measure the diffusion degree of disposable sanitary products such as diapers and sanitary napkins (that is, the quality of diffusion) is to measure the actual diffusion length and width of liquids on disposable sanitary products (urine on diapers or menstruation on sanitary napkins). and area. In the measurement, the diffusion length, width and area are measured at a specific time by adding an equal amount of liquid. The larger the diffusion area at the same time, the better the dryness of the product. Due to the influence of the prismatic groove, the liquid will spread slenderly in one direction along the guide groove or the pressure groove, which makes it impossible to truly measure the diffusion quality of the liquid in the product. [0003] In addition, the diffusion of the liquid on the product is irregula...
