Textile people, do you know about fabric coating?
Coated fabric is a kind of fabric treated with special technology. It can form a uniform layer of covering glue on the surface of the fabric to achieve waterproof, windproof and other functions.
The coated fabric uses solvent or water to dissolve the required coating particles (including PU glue, A/C glue, PVC, PE glue) into a saliva-like shape, and then uses a certain method (cylindrical screen, scraper or roller ) is evenly applied on the fabric (including cotton, polyester, nylon and other base materials), and then fixed by the temperature in the oven to form a uniform layer of covering glue on the surface of the fabric.
There are mainly the following types of fabric coatings:
1. PA coating
Also called AC glue coating, that is, acrylic coating, it is the most common and common coating at present. After coating, it can increase the hand feel, windproof, and drape.
2. PU coating
That is, polyurethane coating. After coating, the fabric feels plump, elastic, and has a filmy feel on the surface.
3. Anti-velvet coating
It refers to the anti-down coating. After coating, it can prevent down from running away and is suitable for making down jacket fabrics. But now, any PA coating with water pressure requirements is also called anti-velvet coating.
4. PA white glue coating
That is, coating a layer of white acrylic resin on the surface of the fabric can increase the covering rate of the fabric, make it opaque, and make the color of the fabric more vivid.
5. PU white glue coating
That is to say, a layer of white polyurethane resin is applied to the surface of the fabric. The function is basically the same as that of PA white glue, but the PU white glue has a fuller feel, more elasticity and better fastness.
6. PA silver glue coating
That is to apply a layer of silver-white glue on the surface of the fabric to make the fabric have light-shielding and radiation-proof functions. It is generally used in curtains, tents, and clothing.
7. PU silver glue coating
The basic functions are the same as PA silver glue coating. However, PU silver-coated fabrics have better elasticity and better fastness. For tents and other fabrics that require high water pressure, PU silver-coated fabrics are better than PA silver-coated fabrics.
8. Pearlescent coating
By applying a pearlescent coating on the surface of the fabric, the surface of the fabric is given a pearl-like luster, which can be silvery white or colored. It makes a very beautiful costume. There are also PA pearlescent and PU pearlescent. PU pearlescent is smoother and brighter than PA pearlescent, and has a better film feel. It is also known as “pearl film”.
9. Oily coating
PaintThe back surface is smooth and shiny, and is generally suitable for tablecloths.
10. Silicone high-elastic coating
Also called paper-like coating. Thin cotton is very suitable for shirt fabrics. It has a plump feel, is brittle and elastic, has strong resilience and is wrinkle-resistant. For thick fabrics, it has good elasticity and fastness.
11. Film coating
By calendering and coating the surface of the fabric, a film is formed on the surface of the fabric, completely changing the style of the fabric. Generally, the leather membrane surface is made into the front of the garment, giving it the style of a leather jacket. There are two types: matte and glossy, and various colors can be added to the coating to make a colorful film, which is very beautiful.
12. Flame retardant coating
By padding or coating the fabric, the fabric has a flame retardant effect. And can be painted in color or silver on the fabric surface. Generally used for curtains, tents, clothing, etc.
13. Teflon three-proof treatment
By treating the fabric with DuPont Teflon, the fabric is waterproof, oil-proof and stain-proof.
14. Anti-UV coating
By applying anti-ultraviolet treatment to the fabric, the fabric has anti-ultraviolet function, that is, the ability to prevent ultraviolet rays from penetrating. Generally, light colors are more difficult to achieve, while dark colors are easier to achieve.
15. Special coating for cotton cloth
Such as: cotton scratch-off coating, paper-feel coating, washed-out coating, hidden grain coating, oil-feel wax-feel coating, colored film coating, etc.
