②Nano waterproof coating


Waterproof fabrics are usually prepared by adding a waterproof coating on the surface of the fabric, and the excellent waterproof properties of the coating are used to give the fabric a waterproof function. However, the waterproof performance of the coated fabric made of traditional waterproof coatings is not stable enough and the durability is poor. If the fabric is in a humid climate environment for a long time (such as walking outdoors for a long time in rainy days), it is very important to ensure the excellent and lasting waterproof performance of the fabric. The combination of nanomaterials and coatings has improved the waterproof performance and durability of waterproof coatings to a certain extent.
