Rayon is manufactured with cellulose materials that are dissolved in which type of chemicals?

Rayon is a regenerated cellulose fiber, and its production involves dissolving natural cellulose sources (such as wood pulp) using specific chemicals. The correct answer relates to the fact that the cellulose is dissolved in alkaline solutions. This process typically uses sodium hydroxide, which is a strong alkaline substance, to break down the cellulose into a viscous solution. This alkaline treatment is essential for obtaining the right consistency and purity needed for fiber formation.

In contrast, while acidic or organic chemicals have their applications in various textile processes, they are not involved in the primary dissolution phase of rayon production. Acidic solutions may damage cellulose or lead to the formation of other types of fibers, which is not applicable in the case of rayon. Similarly, neutral and organic solutions do not provide the necessary reactive environment required for the dissolution of cellulose in the way that alkaline solutions do. Therefore, understanding the chemical behaviors and properties involved in rayon production is key to recognizing why alkaline is the correct choice.
