Maybe you have experienced walking in the rain, wearing your own splash-proof jacket, but walking feels more and more wrong. My clothes are obviously waterproof. Why are they still wet?

"Splash-proof" and "waterproof" are two different things. What's the difference between them?

Splash-proof, also known as pumping water, is called water reprent in English, abbreviated as WR. Splash prevention means that hydrophobic compounds are deposited on the fiber surface, leaving pores on the fabric surface, and air and water vapor can also pass through, generally forming water droplets (such as lotus leaves) on the fabric surface. It is not really waterproof, but reduces the absorption of water by fabrics, so that water can "poke" on the fabric surface, and water will stay in the fabric for a long time.

In the process of splash protection, a layer of ultrafine "needle bed" is attached to the cloth surface with various chemicals, so that the tension of the cloth surface is less than the cohesive force of water, so the water drops behind will form water drops to roll instead of spreading and soaking. If the "needle bed" structure is flattened or covered with oil, the anti-splash ability of the fabric will be greatly reduced, and even it will start to absorb water. The anti-splash effect of fabrics gradually weakens and even fails with washing and long-term use.

Therefore, you can get rid of the water drops on the clothes when you go out in the rain wearing splash-proof clothes, but whether the clothes inside will be wet depends on the amount of rain and the time you stay in the rain. Splash protection is not completely waterproof.

Waterproof:

Waterproof English means waterproof, which means waterproof and moisture permeable fabric. Generally speaking, it refers to making rubber soles at the bottom of fabrics, which can be divided into two categories: coating and lighting. Coatings are usually called coatings, while lamination refers to lamination, that is, compounding a layer of waterproof materials. The vast majority of waterproof fabrics are made of laminated (film) materials, as well as capsule fiber, dense fabric, silicification and other treatment forms, which are usually located in the inner layer of the fabric, commonly known as "waterproof film".

Waterproof membrane is a kind of composite fabric which combines waterproof membrane with other materials and fabrics by sticking process. The fabric itself is not waterproof. Therefore, when we wear waterproof clothes and encounter rain, we will see water seeping into the clothes, just like clothes made of ordinary fabrics, but the inner layer of the clothes is dry, which is the role of waterproof film in the middle of composite fabrics.

Waterproof ability is expressed by the water pressure resistance value of tarpaulin, that is, a fixed area tarpaulin is used to block the rising water pressure. When the third drop of water seeps from the fabric surface, it is the water resistance value of the fabric. Generally speaking, when the water pressure exceeds 1000mmh2o, the most basic waterproof ability can be achieved.
