The principle of coated fabrics
Use a solvent (currently fabric factories generally use toluene or methyl ethyl ketone) to dissolve the required coating rubber particles (including PU glue, A/C glue, PVC, PE glue) into a saliva-like shape (relevant to the rubber material and sol The ratio, viscosity, etc.) is evenly applied on the fabric (including cotton, polyester, nylon and other base materials) with a scraper, and then is fixed by the temperature in the oven to form a uniform layer on the surface of the fabric. Covered with rubber to achieve waterproof, windproof, breathable and other functions!
Coated fabric is a material that has a polymer coating applied to the surface of the fabric. Coatings typically include materials such as polyurethane, polyester, polyethylene, and polypropylene, which can provide water, wind, stain, and UV protection.
The principle of coated fabrics is to apply a polymer coating to the surface of the fabric to form a protective layer, making the fabric waterproof, windproof, anti-fouling, and anti-UV. The coating of coated fabrics can be divided into two types: single-sided coating and double-sided coating.
Single-sided coating is a polymer coating applied to one side of the fabric. This coating can provide waterproof, windproof, stain-proof and other functions. Double-sided coating is a polymer coating applied to both sides of the fabric. This coating can provide better waterproof, windproof, stain-proof and other functions.
The production process of coated fabrics usually includes the following steps:
1. Prepare the fabric: Select the fabric suitable for coating and prepare it, including cleaning, drying and other treatments.
2. Coating preparation: Prepare the polymer coating, usually by melting the polymer particles and coating them on the fabric surface.
3. Coating application: To apply the coating on the surface of the fabric, you can use scraping, roller coating, spraying and other methods.
4. Curing: Curing the coating, usually by heating or ultraviolet radiation.
5. Post-processing: Process the cured coating, including cutting, sewing, etc.
The advantage of coated fabrics is that they have better waterproof, windproof, anti-fouling, anti-UV and other functions, and are suitable for outdoor sports, industrial purposes and other fields.
