What shoes are tested for dynamic waterproofing?

Waterproof shoes are a general term for shoes with a waterproof effect. There are two main types:

1. These are waterproof shoes that are specially worn on rainy days, i.e. rubber shoes. 2. They refer to shoes with certain waterproof effects, such as sports shoes and leather shoes. The best known are waterproof outdoor shoes and sports shoes.

For the materials of dynamic waterproof shoes, rubber, synthetic leather, leather, etc. with better effects are generally used. This article examines and discusses the waterproof performance testing method of finished shoes.

What is the dynamic waterproof test done Shoes? The principle of the test?

The dynamic waterproof test of finished shoes mainly simulates the daily use conditionsments of finished shoes to test their waterproofness under flexing motion. There are three main methods for testing the dynamic waterproofness of finished shoes, namely the water tank test method, the bending waterproof method and the rotating wet brush test method.

Three dynamic waterproofness test methods

1. Analysis of the water tank test method
The water tank test method builds a water tank test system for the waterproofness of finished shoes, which mainly simulates the human body wearing finished shoes and walking a certain distance in the water with a specified value Identified depth at normal speed and tests to determine the extent of water intrusion into the shoes.

Footwear Water Penetration Testing Machine GT-KA02-1 Install finished shoes on the testing machine and fill the tank with A certain depth of water to contact with shoesget. It drives forefoot flexion at a specific angle and frequency by simulating people walking with shoes in water to test the flex times required for water to penetrate from the outside to the inside of the shoes, or around the penetration situation at certain specific bending times.

Standards: SATRA TM77 

2. Analysis of Bending Waterproof Test Method

By placing the finished shoe in the water tank for bending treatment, measure the time it takes for water to permeate into the shoe from the outer surface of the shoe, or the number of flexing.< br />

GT-KA02-2 Dynamic Footwear Water Resistance Tester: The water tank is filled with a specific amount of colored water. A sample is placed on the artificial foot, at a certain angle and mbent at a certain speed and periodically checked for water ingress.

Standards: SATRA TM 230, lSO20344 -2021 section 5.19

3. Analysis of the rotating wet brush test method

The rotating wet brushIn the USH test method, the finished shoe sample is placed in a water tank with a certain depth, and using the rotating wet brush test method, mechanical operations are carried out to correctly check the penetration area of ​​the water.
GT-KA03 Shoe Water Resistance Tester is used to determine the waterproofness of entire shoes. The shoes are mechanically scrubbed with a rotating wet brush at a specified depth of water to measure water penetration into the shoes.

Standards: GB/T 20991-2007 Section 5.15.2,AS/ NZS 2210.2 Section 5.15.2
