Problems solved by technology

Since this test method does not specify the environmental conditions such as temperature, humidity, and wind speed during the test, it is difficult to compare the measurement results of the moisture permeability of different fabrics in different environments, and the test is subject to the subjective randomness of the testers. and the inaccuracy of the calculation method, for this reason, the existing methods of manually detecting the moisture permeability of fabrics still lack a more scientific evaluation of the moisture permeability of different fabrics

Description

Technical field: [0001] The invention belongs to the field of textile measuring instruments, and relates to a novel device and method for detecting the moisture permeability of fabrics. Background technique: [0002] With the development of science and technology and the improvement of living standards, new requirements have been put forward for the comfort of fabrics, including the requirements for moisture permeability of fabrics. The so-called moisture permeability refers to the ability of the fabric to conduct liquid water. In Wang Qi's "Research on the Properties of Modified Soybean Fiber and Moisture-conducting and Quick-drying Functional Knitted Fabrics" (Doctoral Thesis of Donghua University, 2002), he proposed that the water droplet diffusion area be used to represent the moisture permeability of the fabric. The method is: manually drop 0.25ml of water on the fabric, and test the diffusion area of ​​the water drop after 1 minute. In this method, the tester directl...
