What are the uses and advantages of coated fabrics 2021.02.23

In recent years, a coated fabric treated with a special process has become one of the most fashionable and hot-selling varieties. The so-called coated fabric is the coating finishing agent, also known as coating glue-a polymer compound, uniformly coated on the surface of the fabric, through adhesion to form a textile with one layer (or multilayer film).
It can not only improve the appearance and style of the fabric, but also increase the function of the fabric. The popularity of coated fabrics is due to its wide range of products and the popularity of casual clothing in the current apparel consumer market; second, its low-cost production makes its clothing profitable. Medium, low and high-end coated fabrics are available in the market. There are many types of coated fabrics. The products include scratching, leather coated fabrics, colorful film, paper texture, oily wax, printing, foam (foam), waterproof and breathable, flame retardant, silver coated white, pearlescent, Antibacterial, anti-ultraviolet, mercerized leather, matte, anti-dermis, wrinkle leather, etc.
Coated fabrics are widely used. At present, coated products are not only widely used in industry and agriculture, transportation, national defense, hospitals, navigation, fishing, offshore oil wells, decoration, etc., even ethnic minority tents are also favored by them. Autumn and winter clothing fabrics are bright and colorful. They can be combined with knitted fabrics, plain woven fabrics, and non-woven fabrics to make various fabrics or linings. They are suitable for garments, shoes, raincoats, windbreakers, snow jackets, jackets, etc. The original product was only waterproof and not permeable to moisture, the use of coated fabrics had a stuffy feeling and poor comfort.

In recent years, functional coating adhesives and composite coating adhesives have made great progress. The coating results not only have excellent performance in physical properties, uniformity, and stability, but also can be produced in continuous and mass production. There are many classification methods for coating adhesives: according to the chemical structure, there are mainly polyacrylates, polyurethanes, polyvinyl chloride (PVC), silicones, and synthetic rubbers (such as neoprene). In addition, there are polytetrafluoroethylene, polyamide, polyester, polyethylene, polypropylene and protein.
At present, the main applications are polyacrylates and polyurethanes. Polyacrylate type fabric coating adhesive Polyacrylate is one of the commonly used coating adhesives at present. It has good sunlight and weather fastness, and is not easy to yellow; it has good transparency and compatibility, which is beneficial to the production of colored coating products. ; Good washing resistance; strong adhesion; low cost and other advantages. But at the same time, it also has disadvantages such as poor elasticity, easy to wrinkle, poor surface finish, and difficulty in adjusting the hand feeling properly. The original polyacrylate coating glue is a purely waterproof product. Through decades of development, the current variety not only has multiple functions such as waterproof and moisture permeability, flame retardant, windproof, sunshade and foam coating, but also low temperature Energy-saving features. Polyurethane coating glue (Polyurethane for short PU) is called polyurethane. Its advantages are: the coating is soft and elastic; the coating is strong and can be used for very thin coatings; the coating is porous and has moisture permeability And ventilation performance; wear resistance, moisture resistance, dry cleaning resistance. Its disadvantages are high cost; poor weather resistance; hydrolysis when exposed to water, heat, and alkali.
