Problems solved by technology

In order to explore the relationship between fabric structure and wetting performance, we have carried out a series of researches in the past five years. We have done preliminary research on the distribution of capillary warps perpendicular to the plane of the fabric, but so far there is no relevant measurement of the capillary warps along the plane of the fabric. distribution of reports

Embodiment Construction

[0025] The method for measuring capillary pore size distribution of a flexible porous system using a quality classification method of the present invention comprises the following steps:

[0026] a. Prepare flexible porous system materials for measurement, the flexible porous system materials include woven fabrics, knitted fabrics, non-woven fabrics, leather and paper, and trim the samples to a length of 10-150±1cm and a width of 1.0-20±0.1 For a sample of cm, marks can be placed horizontally along the width of the sample at equal intervals of 0.2 to 10±0.1 cm from the lower end of the sample according to the test accuracy requirements;

[0027] b. Liquids prepared for measurement, including all liquids that wet the sample, that is, the contact angle of the liquid to the sample is less than 90 degrees;

[0028] c. Use detergent and / or organic solvent to remove the dirt on the sample, rinse and dry it, then hang it on the suspension device, keep the sample straight and vertical...

Abstract

The invention discloses a method for determining the capillary radius distribution of a flexible porous system by mass classification. The method comprises the following steps of: firstly, preparing a sample plate used for determination, trimming the sample plate into a small test strip with the length of 30(+ / -)1cm and the width of 2.5(+ / -)0.1cm and arranging marks at equal intervals along the width direction from the lower end of the small test strip; secondly, washing and drying the small test strip and hanging the small test strip on a fabric hanging device to enable the lower end of the small test strip to just immerse into a liquid level; then, placing the small test strip and the fabric hanging device together into a constant temperature and constant humidity room and taking down the small test strip after standing for 47 to 49 hours; cutting off the small test strip along the marks; respectively weighing the obtained small test strips and processing data through a formula; andobtaining a fabric capillary radius distribution histogram according to a data processing result and further obtaining a curve distribution graph and an integrogram so that the corresponding relationof the cotton fabric warp and weft density and the capillary radius distribution can be analyzed and compared.

Description

technical field [0001] The invention relates to a method for measuring capillary pore size distribution of a flexible porous system. Background technique [0002] The wettability of fabrics is crucial for both their wet processing and thermo-moisture comfort. The wettability of a liquid to a solid depends on the chemical nature and surface structure of the solid. As a collection of capillary pores that are open at both ends and partially ordered, the wettability of fabrics is usually closely related to its capillary distribution, because whether it is wet processing or wearing, the transportation of water, organic solvents and sweat is mainly in the It is carried out in capillary pores, and the processes involved in adsorption, diffusion, permeation, evaporation, etc. all depend on the structure of capillary pores (shape, roughness, size, distribution, etc.). In view of the complexity of the fabric structure, the current methods for measuring the wettability of fabrics are...
