Fabric coating is to coat the coating material on the fabric by a certain process method to achieve the purpose of changing the performance, function or aesthetic effect of the fabric. Common fabric coating processes are as follows:
1. Coating method: Coating method is the most common kind of fabric coating process, by coating the coating on the fabric, and then by drying and other processes to cure it to form a coating. The coating method is suitable for most fabrics, and different coatings and coating methods can be selected according to the needs, which can realize the functions of waterproof, oil proof, dust proof and so on. Common coating methods include brush coating, roll coating, spraying and so on.
2. Impregnation method: The impregnation method is to impregnate the fabric in the paint bath, let it absorb the paint, and then cure it to form a coating by drying and other processes. Dip method coating uniformity is good, suitable for fabrics and other textiles coating. Common impregnation methods include single bath, double bath, bath ratio impregnation and so on.
3. Commutation method: The commutation method is to make the fabric contact with the coating at a specific position by passing through a certain commutation device, and then cure it to form a coating by drying and other processes. The commutation method is suitable for thin fabric coating and can achieve the effect of one side coating.
4. Gel method: The gel method is to make the coating into a gel shape, and then apply the gel coating on the fabric by printing or smearing and other processes, and then cure it to form a coating by drying and other processes. The gel method is suitable for some fabrics that require high coating thickness and fine pattern effect.
5. Hot melt method: Hot melt method is to heat materials such as hot melt adhesive or hot melt powder to a molten state, and then apply the molten material to the fabric by pressurizing or printing and other processes, and then cure it to form a coating by cooling and other processes. Hot melt method is suitable for some fabric coatings that require high adhesion and durability, such as hot melt adhesive Hot melt method is suitable for the production of hot melt fabric.
6. Dyeing method: Dyeing method is to mix dyes and chemicals, and then through dyeing and chemical reaction and other processes to penetrate the dyes and chemicals into the interior of the fabric fibers, and in the dyeing process, cross-linking, modification and other treatment, in order to achieve the purpose of changing the performance and function of the fabric. Dyeing method is suitable for some fabric coating that needs to change the color and performance of the fabric.
The above is the common fabric coating process, different fabric coating process is suitable for different fabrics and needs, fabric coating manufacturers can choose the appropriate coating process according to the actual situation for production.
