Description

A high-accuracy test device and test method for moisture permeability and moisture absorption performance of finished shoes

technical field

The invention relates to the field of shoe testing, in particular to a high-accuracy testing device and a testing method for the moisture permeability and moisture absorption performance of finished shoes.

Background technique

The water vapor absorption and water vapor permeability of finished shoes are closely related to their comfort and hygiene, and are important factors affecting comfort and hygiene. There are many factors that affect the water vapor permeability and water vapor absorption of the finished shoe. The finished shoe is an irregular composite composed of various materials, including upper materials, shoe lining materials, sole materials, adhesives, inner toe caps, structural design, and shoemaking. Technology, etc., the moisture absorption and moisture permeability test of simple shoe materials cannot truly reflect this performance of shoes.

At present, there are two types of methods for testing, one is the direct steam injection method. The principle is to inject a certain amount of water vapor into the shoe cavity, place it under constant temperature and relative humidity environment conditions, and weigh the test shoes at different placement time nodes ( By analyzing the difference between them and the initial weight, it can be concluded that the water vapor absorption and water vapor permeability of the shoes are good or bad; the second is the sweating prosthetic foot method, and the domestic development principle is mostly made of metal or The foot mold with holes is made of special material. The experimental foot mold is connected to the pipeline and placed in the shoe cavity, and steam is passed through the pipeline. The next test and analysis are the same as the direct steam injection method.

However, since the shoes with the perforated foot mold and the steam pipeline need to be disassembled and taken out of the test box for measurement after the steam is passed in, the test data is easily affected during the process of taking out the shoes. There is also the fact that it is easy to condense into water droplets during the steam transportation process, and the condensed droplets in the pipeline are easy to drip into the sole of the shoe and be absorbed by the shoe, which will inevitably weaken the reasonable authenticity of the test data.

In view of this, the applicant has conducted in-depth research on the above-mentioned defects in the prior art, resulting in this case.
