We can apply dual function on both knit and woven fabrics. One side of the fabric can be water repellent, the other side can be moisture wicking. This combination will be great for pants because it can absorb sweat one side and water repel on the other. Another great application is to use it on t-shirt, polo, and shirts, it will have sweat hiding function because the sweat absorbed will not reflect on the outside.
*PS*: The base fabric cannot be too thin.
