Rayon is commonly found in summer textiles. Because of the word “cotton” in the name, it is often mistaken for a type of cotton. ,actually not. Not only is rayon unrelated to cotton, its fiber characteristics are also very different from cotton. Today we will get to know the fabric “rayon”.

What is rayon?
Rayon is a very old fiber variety, which has been around for hundreds of years since its introduction in 1893.
Rayon is also what we often call artificial cotton/rayon, which is listed in the fabric ingredient label The common “viscose fiber” is essentially a type of regenerated fiber and has nothing to do with cotton. The English name of viscose fiber is viscose. It is an artificial fiber extracted from cellulose raw materials such as wood and plant stalks, or cotton linters as raw materials, processed into spinning solution, and then wet-spun. fiber.

What are the characteristics of rayon
1. Fabric Soft and smooth
The rayon fiber is even in thickness, with very few yarn defects and no impurities, so the cloth surface is smooth and shiny, delicate and smooth, comfortable and skin-friendly.
2. Good moisture absorption and breathability
When the ambient temperature is 20℃ and the humidity is 60%, the official moisture regain of rayon is 13%. It is about 50% higher than the official moisture regain of cotton of 8.5%. Because there are many grooves on the surface of the fiber, it can quickly conduct moisture and has good breathability. Therefore, it is not easy to generate static electricity, is not easy to be contaminated by dust, is easier to dye, and has higher brightness and color fastness.

3. Thermal conductivity Good sexual performance
When the ambient temperature is 20℃ and the humidity is 60% Under normal circumstances, the thermal conductivity of rayon is 0.055-0.077. When the fabric comes into contact with the skin, it can quickly conduct body heat into it, giving people a cool feeling. Therefore, some ice silk bedding products on the market are made of it as the main raw material.
4. Easy to shrink and not resistant to washing
Rayon has excellent hydrophilicity and will expand significantly after absorbing moisture, with the diameter increasing by up to 50% , so the fabric feels hard after being put into water, is prone to shrinkage and deformation, and has poor elasticity and wear resistance. Therefore, there are few 100% rayon fabrics on the market, and most of them are blended with other fibers, such as polyester fiber, cotton, linen and other fibers.
5. Poor acid and alkali resistance
Rayon is resistant to alkali but not acid, but its resistance to alkali and acid is worse than cotton, so washing this type The product needs to be washed with neutral detergent.

What is the difference between rayon and cotton?
1. Finish: Artificial cotton, The cloth surface is smooth, with few yarn defects, no impurities, and is delicate and smooth; while cotton cloth may have impurities such as cotton husks and branches, and its smoothness is not as good as that of artificial cotton.
2. Yarn count uniformity:The yarn count of artificial cotton cloth is uniform in thickness and has few yarn defects; while the yarn count of pure cotton cloth is not as uniform as that of artificial cotton, especially the medium and thick yarn count.
3. Feel: Man-made cotton fabrics, no matter how thick or thin they are, have the best hand feel. It is softer and smoother, while cotton has a slightly rough feel and a slight resistance to the touch.
4 , Color:Artificial cotton cloth has good luster and color. Compared with cotton cloth, artificial cotton cloth is more bright and beautiful.
5. Wrinkling: Artificial cotton is easy to wrinkle and It is not easy to recover in time; although cotton has wrinkles, the degree of wrinkles is lighter than that of artificial cotton.
6. Drapeability:Although rayon is light and thin, However, the drape of cotton is not as good as that of artificial cotton.
7. Price: Rayon<cotton, raw material, Differences in production technology, performance, etc. also create price differences between the two. The current price of cotton on the market is about twice that of viscose fiber.
Xiaoyuanxiang here One thing that everyone should pay attention to is that regarding the difference between rayon and cotton, there is a saying in the industry that the burning state of rayon and cotton is different, but this is not the case. The main raw material of rayon is plants, so its burning characteristics are the same as rayon: it does not melt or shrink, burns quickly, smells of burning paper when burning, and the residue after burning is a small amount of grayish white… Don’t be misunderstood anymore!
