The breathability of the post film fabric mainly depends on the choice of material and process. Generally speaking, post film fabrics are more breathable, can effectively sweat and keep the skin dry. Post film fabrics are usually made of special fibers with breathability, such as breathable mesh fabrics or breathable synthetic fibers. These materials allow air and water vapor to pass through the interior of the fabric, which improves the breathability of the garment and makes the wearer feel more comfortable.

In addition, the breathability of the post-film fabric is also affected by the process treatment. In the production process, different technical treatments can be used to improve the breathability of fabrics, such as adding breathable coatings or special weaving methods. These processes can effectively improve the breathability of the post-film fabric, so that the wearer can remain comfortable in sports or high temperature environment.

Overall, the breathability of a membrane fabric is a combination of materials and processes. Selection of breathable fabrics and the use of appropriate technology can improve the breathability of the film fabrics, so that the wearer feels better comfort in the wearing process. I hope the above analysis will be helpful to you.
