Coating Knowledge


 Coating fabric is a specially treated fabric. It can form a uniform covering compound on the surface of the fabric to achieve waterproof, windproof and other functions.


The coating fabric is dissolved in a flowing form by using a solvent or water to dissolve the required coating rubber (with PU glue, A/C glue, PVC, PE glue), etc., in a certain way (round net, scraper or roller) Uniformly applied to the fabric (with cotton, polyester, nylon and other substrates), and then through the temperature of the oven to form a uniform covering compound on the surface of the fabric.


The main types of fabric coatings are as follows:


01: PA coating

Also known as AC glue coating, that is, acrylic coating, it is the most common and most common coating at present. After coating, it can increase the hand feeling, windproof and drape.



02: PU coating

That is, the polyurethane coating, the coated fabric feels full, elastic, and has a filmy feel on the surface.


03: Anti-velvet coating

It means anti-down coating, which can prevent down running 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.


04: PA white plastic coating

That is, applying a layer of white acrylic resin on the surface of the fabric can increase the coverage of the cloth surface, prevent color penetration, and make the color of the cloth surface more vivid.


05: PU white plastic coating

That is, a layer of white polyurethane resin is applied on the surface of the fabric, which is basically the same as PA white glue, but the PU white glue is more full after application, and the fabric is more elastic and has better fastness.


06: PA silver coating

That is to say, a layer of silver-white glue is applied on the surface of the fabric to make the fabric have the functions of shading and radiation prevention, and are generally used for curtains, tents and garments.
