Step 1: Dry the dyed or whitened cotton fabric for later use.
Step 2: Mix the adhesive, water- and oil-repellent agent, thickener and demineralized water evenly according to mass percentage to make a slurry.
Step 3: Send the cotton fabric to the printing machine, use discontinuous rotary screen printing technology to coat the outer surface of the fabric, and then dry it.
Step 4: Send the dried cotton fabric to the stenter setting machine for baking treatment to enhance the waterproof effect.
Step 5: Add a hydrophilic agent in the rolling groove of the tenter setting machine according to a certain proportion, and then send the baked cotton fabric to the tenter setting machine again, and hydrophilize the inner surface of the fabric that has not been coated. Water finishing and stenter setting.

Characteristics of single-sided moisture-wicking cotton fabric
In the production and processing of single-sided moisture-wicking cotton fabrics, the coating treatment only affects one side of the fabric with slurry applied, and has no effect on the other side of the fabric; while hydrophilic finishing is aimed at fabrics that have not been smeared with slurry. One side has no effect on the other side. Therefore, the fabric processed by this process has excellent water- and oil-repellent properties on the side where the slurry is applied, while the other side will show excellent hydrophilic and moisture-conducting properties without affecting the water- and oil-repellent effect. . Generally speaking, the characteristics of this kind of fabric are as follows:
The front side of the fabric, that is, the outer surface of the fabric, adopts environmentally friendly water-based coating finishing technology. Using rotary screen printing, an interface structure with complementary geometric shapes can be formed on the surface of the fabric, so that this side of the fabric has excellent water- and oil-repellent properties;
The reverse side of the fabric, that is, the inner surface of the fabric, adopts special hydrophilic treatment technology. According to the pressure and suction finishing method, the fabric can show excellent hydrophilic and moisture-conducting properties without affecting the waterproof and oil-proof properties of the front side of the fabric;
