Textile waterproofing agent is a kind of chemical coating on the surface of textiles, its main components include fluorocarbons, silicone, acrylates and so on. These compounds can form a waterproof film on the surface of the textile, preventing the penetration of water molecules, thus achieving the effect of waterproof.

Waterproof refers to the liquid water dripping on the surface of the textile, will not directly penetrate into the fabric inside, but to achieve a lotus leaf effect, in the form of water drops in the fabric surface rolling, but the textile surface still has a gap, water molecules will penetrate into the inside, if a long time to stay, water will slowly penetrate into the textile inside, if under the action of pressure, Water also seeps into the fabric.

The principle is to reduce the surface tension of the fabric, so that the surface tension of the fabric is lower than the surface tension of the water, so that when the water drops to the surface of the fabric, it is not easy to penetrate into the inner layer of the fabric, and stay in the surface of the fabric in a beaded form, resulting in an oil-repellent effect.

For a simple example, usually other people pour water on your body, you and your friends play by the river, your friend suddenly very skin to pour water on your body, because your clothes have been waterproof finishing, the water will roll down in the form of water, but will not quickly penetrate into the clothes inside. If you do not do waterproof finishing, then your clothes will be easily wet by the river water.

Fabric waterproof finishing, also called water repellent finishing, water finishing, they are the same meaning, but the name is different. At present, there are three main categories of Deco nano waterproofing agents, which are carbon eight, carbon six and fluorine-free waterproofing agents.

Waterproofing agents can be roughly divided into two categories: fluorine-containing waterproofing agents and fluorine-free waterproofing agents. In terms of performance, the waterproofing effect of fluoride-free waterproofing agent is outstanding, and the finished fabric has excellent anti-splashing and anti-siphon effects. The water repellent containing fluorine has better water and oil repellent effect and good water washing resistance. However, fluorine-free waterproofing agent does not contain fluorine compounds, compared with fluorine-based waterproofing agent, it is not easy to deposit in the biological body, easy to degrade, harmless to the human body, and is a more safe and environmentally friendly product. In today's increasingly popular concept of ecological environmental protection, fluoride-free waterproofing agents are more easily accepted by fabric processing plants.
