    Currently, the waterproofing agent on the market is mainly classified into a fluorocarbon waterproofing agent and a non-fluorine-based waterproofing agent. That is what we often say: C8 waterproofing agent, C6 waterproofing agent and fluorine-free waterproofing agent. Although the water repellent has certain differences in principle, the waterproof treatment process is not much different. How to produce a high quality waterproof fabric?

    1. There are many types of fabrics. The structure, thickness and characteristics of different fabrics are different. When we get the fabric to be tested, we need to determine what kind of fabric it belongs to, so that we can roughly judge the suitable process conditions.

    2. Confirm that the fabric to be treated has been previously finished, such as soft finishing.

    3. Confirm that the fabric surface is clean? Does it contain impurities? Impurities are further divided into impurities in the fabric itself (pre-treatment is not cleaned), and there is also a foreign impurity (pre-treatment, additional additives when dyeing); if there are impurities on the surface of the fabric, the waterproof effect will be greatly reduced.

    4. Cloth PH value? Yes, it is the PH value of the fabric, and the PH value of the fabric will affect the waterproof effect.

    The above is a problem that must be paid attention to before making waterproof finishing. It is also necessary to prepare the finishing fabric correctly. Only when the preparation is sufficient, our next waterproof finishing can be carried out more smoothly.
