The working principle of waterproof Oxford fabric is : In the state of water vapor, the water particles are extremely fine. According to the working principle of capillary movement, they can smoothly penetrate into the capillary tube to the other side, thus producing breathability. When the water vapor condenses and turns into water droplets, the particles increase. Due to the surface tension of the water droplets (the water molecules “pull and compete” with each other), the water molecules cannot smoothly escape from the water droplets and penetrate to the other side, that is, to prevent the water from Penetration occurs, making the breathable membrane waterproof.
After checking the quality of the test cup (including sample, desiccant and film) with the film facing upward, Quickly invert the test cup and pour it into the sample holder. This assembly method is placed in a temperature controlled equipment of 30℃±2℃. After 15 minutes, take the testing cup out of the temperature control device, turn it upside down and measure its total weight. Most of the waterproof Oxford fabrics based on this testing method can achieve waterproof and moisture-proof functions.
There are various testing methods for waterproof Oxford fabrics. Currently, the most popular method for testing waterproof Oxford fabrics at home and abroad is Practical steps are as follows: All coated or laminated fabrics are fixed to the support frame with rubber rings, with the coated or laminated side facing outwards. The installation of the sample support system shall be subject to being able to float in a water tank with a water temperature of 23°C.
