Depending on the material of the coating, there are three major categories of PVC coating, PU coating and semi-PU coating.
According to the different coating process, there are silk leather, matte surface, anti-leather, wrinkle leather and so on.
Also classified according to function and characteristics. Such as: coloring glue, PVC coating, silver coating, calendering, flame retardant, PA moisture permeability, PU moisture transparent and so on. Special coating: rubber coating, paper processing, waterproof and moisture permeable, pearl series, oil wax coating, PU gold glue silver glue, high water pressure series (up to 1000---10000), UV- CUT is UV resistant and so on.
The principle of coated fabric
Using solvents (now the fabric factory generally uses toluene or methyl ethyl ketone) to dissolve the required coating rubber particles (with PU glue, A / C glue, PVC, PE glue), etc. into a flowing state (related to the compound and sol The ratio, viscosity, etc.) is evenly applied to the fabric by a scraper (with cotton, polyester, nylon, etc.), and then fixed in the oven to form a uniform layer on the surface of the fabric. Cover the rubber to achieve waterproof, windproof, breathable and other functions!
the type of current coating finishing
1.PA coating, also known as AC glue coating, that is, acrylic coating, is the most common and most common coating at present, after adding, it can increase the hand feeling, windproof and drape.
2.PU coating, that is, polyurethane coating, after coating, the fabric feels full, elastic, and the surface has a film feel.
3. Anti-velvet coating, which means anti-down coating, can prevent down run after coating, suitable for down jacket fabric. However, any PA coating that has water pressure requirements in the coating is also called an anti-velvet coating.
