Whether the disposable face towel will smell when wet with water has a lot to do with the material. There are two main materials for face towel on the market, one is natural pure cotton and the other is viscose fiber. The pure cotton face towel is made of natural materials and has no peculiar smell after being wet with water. If you smell it carefully, there will be a faint smell of natural cotton. The face towel made of viscose fiber will smell when wet, which is determined by its production process. Viscose fiber is extracted from cellulose raw material to pure α-cellulose, treated with caustic soda and carbon disulfide to obtain orange-yellow cellulose sodium xanthate, which is then dissolved in dilute sodium hydroxide solution to become a viscous spinning dope , called viscose. After the viscose is filtered, aged and defoamed, wet spinning is carried out, and the coagulation bath is composed of sulfuric acid, sodium sulfate and zinc sulfate. The cellulose sodium xanthate in the viscose is decomposed by the action of sulfuric acid in the coagulation bath, the cellulose is regenerated and precipitated, and the obtained cellulose fiber becomes viscose fiber after washing, desulfurization, bleaching and drying. It can be found from the production process of viscose fiber that it has a production step of adding carbon disulfide, etc., which contains sulfide and needs to be treated before use. If the treatment is not good, sulfide will be left, and sulfide is Flavorful. The disposable face towel I bought will smell burnt when wetted with water. It can be judged that: 1. It is not pure cotton. Second, there are sulfide residues.
