How to distinguish waterproof fabrics from water-repellent fabrics?

Many people confuse water-blocking fabrics with water-repellent fabrics. In fact, they are very different in nature. Do you know which fabrics are used in Outdoor Jackets and raincoats respectively? I believe you will be able to differentiate between these two fabrics after reading the article.

How to distinguish waterproof fabrics from water-repellent fabrics?

The essence of wave-proof water fabric is that hydrophobic compounds are deposited on the fiber surface. There will be many gaps on the surface of the fabric, but only moisture and air can pass through, while water droplet-shaped liquid cannot pass through, but it has not been done. In the true sense of water blocking, it will still penetrate into clothing over time. This is also the main basis for distinguishing water-repellent fabrics from water-repellent fabrics.

The principle of water-repellent is to attach a layer of hydrophobic chemical material to the cloth surface, causing the tension of the cloth surface to be smaller than the cohesive force of water. When water droplets come into contact with the cloth surface, they will spread out instead of penetrating into it, so this If the layer structure is damaged, the fabric will lose its water-repellent function, because the water-repellent function of the wave-proof water-proof fabric will weaken and disappear with the use of time.

Water-blocking fabric is to add a layer of rubber bottom (water-repellent PU coating) to the bottom of the fabric. This water-repellent PU coating is usually made of capsule fiber or silicone, which can make it waterproof. Water-repellent fabrics block water.

To sum up, the water-proof fabrics do not have long-term water-blocking properties. The long-term water-blocking properties of water-proof fabrics and their production principles are also different. The principle of the former is that the tension of the fabric is higher than that of water. Cohesion, while the latter is directly added with a layer of water-repellent PU coating. You can distinguish them through these two points in the future. Of course, there are also a variety of water-repellent fabrics for sale. Here are some recommended water-blocking fabrics that sell well.
