Detailed explanation of coating finishing technology
PU coating, also called glue PU coating, is acrylic PU coating, which is a common PU coating at present. 1. PAPU coating, also called AC glue PU coating, that is, acrylic PU coating, is a common PU coating at present. After coating, it can increase the hand feel, block wind, and have a drapey feel. 2. PUPU coating, that is, polyurethane PU coating, the fabric feels full and elastic after coating, and the surface has a filmy feel. 3. Anti-down PU coating refers to anti-down PU coating. After coating, it can prevent down from running away and is suitable for making down jacket fabrics. But now among PU coatings, any PAPU coating that requires water pressure is also called anti-velvet PU coating. 4. PA white glue PU coating, that is, coating a layer of white acrylic resin on the surface of the fabric, can increase the covering rate of the cloth surface, make it opaque, and make the color of the cloth surface more vivid. 5. PU white glue PU coating is to apply a layer of white polyurethane resin on 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 after coating, the fabric is more elastic and the fastness is better. 6. PA silver glue PU coating is to apply a layer of silver-white glue on the surface of the fabric to make the fabric fully covered and prevent radiation. It is generally used in curtains, cotton tents, and work clothes. 7. PU silver glue PU coating, the basic functions are the same as PA silver glue PU coating. However, PU silver-coated fabrics have better elasticity and better fastness. For fabrics such as cotton tents that require high water pressure, PU silver-coated fabrics are better than PA silver-coated fabrics. 8. Bead-finished PU coating, by bead-finishing PU coating on the surface of the fabric, the surface of the fabric will have a pearl-like luster, with silvery white and colored colors. It’s especially beautiful as work wear. There are also PA bead finish and PU bead finish. PU bead finish is flatter and brighter than PA bead finish, has a better film feel, and is known as “pearl skin film”. 9. After oiling the PU coating, the surface will be completely smooth and shiny. It is generally suitable for tablecloths. 10. Silicone high-elastic PU coating, also called paper-like PU coating. Thin cotton fabric is very suitable for shirt fabrics. It has a full feel, is brittle and elastic, has strong resilience and is wrinkle-resistant. For thick fabrics, it has good elasticity and fastness. 11. Film PU coating: By pressing and PU 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 surface is made into the front of work clothes, with the style of leather jacket. There are two types: sub-fin and finished, and various colors can be added to the PU coating to make a colored film, which is particularly beautiful. 12. Fireproof PU coating, through padding or PU coating treatment on the fabric, the fabric has a fireproof effect. And can be painted in color or silver on the fabric surface. Generally used as curtains, cotton tents, work clothes, etc. 13. Teflon three-proof treatment. By treating the fabric with DuPont Teflon, the fabric has the functions of water-blocking, oil-proof and decontamination. 14. Anti-UV PU coating, through anti-UV treatment on the fabric, makes the fabric anti-UV, that is, the ability to block the penetration of ultraviolet rays. Generally, light colors are more difficult to do, while dark colors are easier to achieve. 15. There are also PU coatings specially designed for cotton, such as: cotton scratch-colored PU coating, paper-feel PU coating, washed-out PU coating, hidden-grain PU coating, oil-feel waxy PU coating, and colored film PU Coatings and more.
