How to ensure that PU coated fabrics can maintain their waterproof properties after long-term use and multiple washings?

Ensuring that PU coated fabrics can maintain their waterproof properties after long-term use and multiple washings can be achieved in the following ways:

Choose high-quality PU coating materials:

Use high-quality polyurethane materials for coating. High-quality PU materials have better wear resistance and washability, and can maintain their structural integrity and functionality after multiple washings.

Optimize coating process:

Use advanced coating technologies such as multi-layer coating and nanotechnology. These processes can enhance the adhesion and durability of the coating, so that it can maintain its waterproof properties after frequent use and washing.

Post-treatment protection:

After the coating is completed, the fabric is subjected to additional protective treatment, such as adding detergent resistance or heat treatment. These methods can further improve the durability and stability of the coating.

Enhance adhesion:

Before coating, ensure the surface of the substrate (fabric) is cleaned and treated to increase the adhesion of the PU coating to the substrate. Stronger adhesion helps prevent the coating from falling off during the washing process.

Research and develop improved formulas:

Through the research of chemistry and materials science, the formula of PU coating is continuously improved to make it have better hydrolysis resistance and aging resistance, and can maintain stable waterproof performance in various environments.

Regular maintenance and care:

Provide cleaning and maintenance guidelines, and recommend the use of appropriate cleaning agents and cleaning methods to avoid damage to the coating. At the same time, it is recommended to use waterproof spray or coating repair agent for maintenance regularly to extend the service life of the coating.

Strict testing and quality control:

Strict quality control and testing are carried out during the production process, including washability test, aging test and waterproof performance test, to ensure that each batch of products can meet the expected durability and waterproof performance standards.

Through the above methods, it can effectively ensure that PU coated fabrics can still maintain their excellent waterproof performance after long-term use and multiple washings.
