What is coated cloth? Types of coated cloth, perhaps we have all heard of coated cloth, but do we really understand coated cloth? Know what is coated cloth? Do you know his classification? GoldGold Textile (Huizhou) Co., Ltd. will learn about coated fabrics with you.
1. Classification
According to different coating materials, there are three types of PVC coatings, PU coatings and semi-PU coatings.
There are also classifications based on functions and characteristics. Such as: color glue, PVC coating, silver coating, calendering, flame retardant, PA moisture permeability, PU moisture permeability and transparency, etc. Special coating: rubber-like coating, paper-like processing, waterproof, moisture-permeable and breathable, pearlescent series, oil-wax-like coating, PU gold and silver glue, high water pressure resistance series (up to 1000---10000), UV- CUT anti-ultraviolet processing and so on.
2. The principle of coated fabrics
Use a solvent to dissolve the required coating particles (PU glue, A/C glue, PVC, PE glue) into a salivating shape (related to the ratio of glue and sol, viscosity, etc.) and then use a scraper The method is evenly coated on the fabric (polyester, nylon and other substrates), and then fixed by the temperature in the oven, so that a layer of uniform covering rubber is formed on the surface of the fabric, so as to achieve waterproof, windproof, and steam-permeable functions!
3. Types of current coating finishing
1. PA coating, also known as AC glue coating, that is, acrylic coating, is a common and common coating at present. After coating, it can increase the hand feeling, windproof and drape. There are also acrylic and pony glue, that is, solvent-based acrylic coatings, which are suitable for water pressure-resistant coatings, and the price is slightly higher than AC.
2. PU coating, that is, polyurethane coating, the fabric feels plump and elastic after coating, and the surface has a filmy feel.
3. Anti-down coating refers to anti-down coating, which can prevent down from running down after coating, and is suitable for down jacket fabrics. But now all PA coatings with water pressure requirements in the coating are also called anti-fleece coatings.
4. PA white glue coating, that is, coating a layer of white acrylic resin on the surface of the fabric, which can increase the covering rate of the fabric surface, impervious to color, and make the color of the fabric surface more vivid
5. PU white glue coating, that is, to coat a layer of white polyurethane resin on the surface of the fabric, the effect is basically the same as that of PA white glue, but the hand feeling of PU white glue is more plump, the fabric is more elastic, and the fastness is better.
6. PA silver glue coating, that is, coating a layer of silver white glue on the surface of the fabric, so that the fabric has the function of shading and radiation protection, and is generally used for curtains, tents, and clothing.
7. PU silver glue coating, the basic function is 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, through the pearlescent coating on the surface of the fabric, the surface of the fabric has a pearly luster, silvery white and colorful. Made into a very beautiful costume. There are also PA pearls and PU pearls. PU pearls are smoother and brighter than PA pearls, and have a better film feel, and they are also known as "pearl film".
9. Glossy coating, the surface is smooth and shiny after coating, generally suitable for tablecloths.
10. Silicone high-elastic coating, also known as paper-like coating. For thin cotton fabrics, it is very suitable for shirt fabrics. It feels plump, brittle and elastic, and has strong resilience and wrinkle resistance. For thick fabrics, it has good elasticity and fastness.
11. Film coating, through calendering and coating on the surface of the fabric, a film is formed on the surface of the fabric, completely changing the style of the fabric. Generally, the skin surface is made into the front of the garment, which has the style of a leather garment. There are two kinds of 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, through padding or coating treatment of the fabric, the fabric has a flame retardant effect. And can be painted in color or silver on the surface of the fabric. Generally used as curtains, tents, clothing, etc.
13. Teflon three-proof treatment, by treating the fabric with DuPont Teflon, the fabric has the functions of waterproof, oil-proof and anti-fouling.
14. Anti-ultraviolet coating, through the anti-ultraviolet treatment of the fabric, the fabric has the function of anti-ultraviolet, that is, the ability to prevent the penetration of ultraviolet rays. Generally, light colors are more difficult to do, and dark colors are easier to meet the standard.
15. PVC coating, PVC coated Oxford cloth has excellent mildew resistance, obvious waterproof, non-flammability, strong tensile force, high strength, weather resistance and excellent geometric stability. PVC has strong resistance to oxidizing agents, reducing agents and strong acids, and has a wide range of uses. After coating, the surface is smooth and shiny, and it is generally suitable for making tablecloths and tablecloths.
16. Foaming coating requires a separate foaming machine to prefabricate the slurry. It is often used for curtain fabrics, with soft and thick hand feeling and shading.
