Why does the face towel smell like burning? Are viscose face towels good?

In daily life, we often see that many people like to use disposable face towels. Disposable face towels are very clean and hygienic, and are currently recommended by many people as facial products. But why does the face towel smell burnt after being soaked in water? Why does the face towel smell burnt?

Why does the face towel smell like burning?

Maybe the face towel you bought is made of viscose, which may have a burnt smell when wet. This is mainly because during the production process of viscose fiber, there is a production step of adding carbon disulfide, etc., which contains sulfide and needs to be processed before use. If it is not processed properly, sulfide will be left behind. Sulfide has a smell and will have a burnt smell when it comes into contact with water.

The specific reason why the face towel has a burnt smell

Whether a disposable face towel will have a smell when it comes into contact with water has a lot to do with its material. There are two main types of face towel materials on the market, one is natural cotton and the other is viscose fiber. The pure cotton face towel is made of natural materials and has no odor after being wetted with water. If you smell it carefully, there will be a faint smell of natural cotton. The face towel made of viscose fiber will have a smell when wet, which is determined by its production process.

Viscose fiber is made by extracting pure α-cellulose (called pulp) from cellulose raw materials, treating it with alkali and carbon disulfide to obtain orange-yellow cellulose sodium xanthate, which is then dissolved in a dilute sodium hydroxide solution to become a viscous spinning solution, called viscose. After filtering, aging (standing at a certain temperature for about 18 to 30 hours to reduce the esterification degree of cellulose xanthate), and degassing, the viscose is wet-spun, and the coagulation bath consists of sulfuric acid, sodium sulfate and zinc sulfate. The sodium xanthate of cellulose in the viscose reacts with the sulfuric acid in the coagulation bath to decompose, and the cellulose is regenerated and precipitated. The obtained cellulose fiber becomes viscose fiber after washing, desulfurization, bleaching and drying.

From the production process of viscose fiber, we can find that one of its production steps is to add carbon disulfide, etc. It contains sulfide and needs to be processed before it can be used. If it is not processed properly, sulfide will be left behind, and sulfide has a smell. If the disposable face towels you buy have a burnt smell when they come in contact with water, you can tell: 1. They are not made of pure cotton. 2. There are sulfide residues.

Are viscose face towels good?

Face towels made of viscose fiber can be used occasionally by people with non-sensitive skin. After all, the price is relatively affordable. However, if used for a long time, it will definitely cause certain harm to the skin. If conditions permit, it is recommended to choose a pure cotton face towel.

What is viscose fiber

Viscose fiber, abbreviated as viscose, is a cellulose fiber obtained by extracting and reshaping the fiber molecules from natural wood cellulose using "wood" as raw material. Viscose is one of the oldest fiber varieties. Viscose fiber is a type of man-made fiber. The hygroscopicity of viscose fiber meets the physiological requirements of human skin. It has the characteristics of smoothness, coolness, breathability, anti-static, UV protection, bright colors and good color fastness. It has the essence of cotton and the qualities of silk. It is a genuine plant fiber, derived from nature but superior to nature. It is widely used in all kinds of underwear, textiles, clothing, non-woven and other fields.

Advantages of viscose fabric

Viscose fabric has super anti-static properties. It does not feel sticky to the body and is therefore very smooth, making it particularly suitable for making sportswear. The moisture content is also the most in line with the physiological needs of human skin, and it also has good air permeability and humidity regulating functions, and is called "breathing fabric". The finished garments have the advantages of soft touch, smooth and cool, breathable, anti-static, and gorgeous dyeing.

Disadvantages of viscose fabric

Although this fabric has many advantages, we have to mention some of its disadvantages. Due to the material problem of viscose fiber, it is relatively heavy, so its elasticity is poor. If squeezed and rubbed, it will easily wrinkle, and its recovery performance is poor, making it difficult to restore to its original state. In addition, viscose fabric is not resistant to washing. If washed for a long time, it will cause hair loss, pilling and shrinkage.
