Method for measuring fluid absorption in personal hygiene articles
The patent application (Publication Number: US20240033142A1) describes a method for determining the grayscale value of a personal hygiene article by acquiring images from an imaging device, obtaining data sets from these images, estimating a grayscale value for fluid flow, calculating a theoretical flow rate, and generating a final grayscale value based on the volume of data sets. The method involves utilizing linear regression or derivatives of curves to calculate flow rates, comparing errors, and adjusting grayscale variables to refine the estimation process.
Furthermore, the patent application details a method for measuring fluid absorption and retention in personal hygiene articles by obtaining a reference sample, inputting mass data into a computer, positioning the sample near an imaging device, and pumping fluid through a line connected to the sample. The computer coordinates the pump and imaging device, estimates grayscale values for fluid flow, calculates theoretical flow rates, and adjusts grayscale variables to generate final values. This method allows for accurate measurement of fluid absorption and retention in personal hygiene articles, enhancing product development and quality control processes.
