Rayon, also known as artificial silk or imitation silk, is a textile with the look and feel of silk created using chemical fibers. It is not a natural material, but a fiber synthesized through a chemical process, making it significantly different from natural silk in terms of performance and price. In this article, we will discuss in depth the characteristics, types, and differences between rayon and silk.
1. Production process of rayon
The production process of rayon is complex and involves a variety of chemicals and processes. Generally, it begins with the extraction of cellulose, usually from wood pulp or cotton. The cellulose is then subjected to a series of chemical treatments that convert it into a soluble solution. This solution is then extruded through tiny nozzles to form filaments. These filaments solidify in air or water to form continuous fibers. Finally, these fibers are finished and processed to make a variety of rayon fabrics. The production process may vary slightly for different rayon types.
2. Types and Properties of Rayon
Rayon is not a single material, but contains many different types of fibers. Common rayon fibers include viscose fiber, acetate fiber and copper-ammonia fiber. They differ in gloss, feel, strength, moisture absorption and durability.

Rayon Types |
Characteristics |
Advantages and Disadvantages |
|
Viscose fiber |
Glossy and soft, soft feel, good moisture absorption, relatively inexpensive |
Easy to wrinkle, lower strength, poor light resistance, susceptible to moisture |
|
Acetate fiber |
Glossy, good drape, washable, not easy to wrinkle |
Poor moisture absorption, lower strength, flammable |
|
Copper ammonia fiber |
Glossy and bright, soft feel, high strength |
High production costs, relatively narrow range of applications |
3. The difference between rayon and silk
Although the appearance of rayon and silk are similar, but the essence of the huge difference. Silk, that is, natural silk, is formed by the silkworm spit cocoon of natural protein fibers, with a unique soft luster, excellent moisture absorption and breathability, as well as good warmth. Rayon is a synthetic fiber, and its properties differ significantly from those of silk.

4. Applications of Rayon
Because of its relatively low price, rayon is widely used in clothing and home textiles. For example, rayon is often used to make shirts, dresses, skirts, underwear, bed sheets, quilt covers and so on. Some high-end rayon products can also achieve a better texture after special treatment, but they are still not comparable to real silk.
5. How to identify real silk and rayon
There are many ways to identify real silk and rayon, such as the burning method, the feel method, the washing method. Burning method: silk burning will produce the odor of burnt feathers, while rayon burning will produce the odor of burning plastic. Feel method: silk feel soft, smooth, and rayon feel relatively rough. Washing method: silk will shrink slightly after washing, while rayon will change less after washing.,
Rayon and natural silk in the material, performance and feel of the essential difference. Consumers should choose the right material according to their own needs and budget, and should not confuse rayon with silk. Understand the characteristics of rayon in order to better choose the right product for you.
