In a standard laboratory, spray distilled water on the sample through a funnel, and compare the rating with a waterproof standard sample.

Common test standards are American Standard: AATCC 22; European Standard: ISO 4920.

There are three types of anti-splashing water: ordinary waterproof (WaterRepellent, abbreviated as: W/R), waterproof water (DurableWaterRepellent outdoor fabric industry is commonly known as super splash water, abbreviated as: DWR), Teflon (TEFLON) waterproof:

1. Ordinary waterproof (W/R): The surface of the clothes is not waterproof after washing it for a few times. Ordinary outdoor leisure is usually waterproof. If you go to mountain climbing or a mountain with a certain altitude, the weather on the mountain is fickle and it may rain at any time. Ordinary waterproof clothing is washed several times without waterproofing, causing the surface of the clothing to get wet, and wearing the body will increase the body weight.

2. Super water repellent (DWR): Japan’s Daikin’s carbon 6 is waterproof, which maintains 80 points (European standard 3) after 20 times of washing.

3. Teflon (TEFLON), produced by DuPont in the United States, is waterproof, antifouling, and oil resistant, and the price is relatively expensive. Teflon hang tags can be provided to buy this brand of waterproof, but the shortcomings of Teflon are not as good as carbon 6.
