• D. Drying $\to$ Finishing $\to$ Pulping $\to$ Mixing additives

Answer 1

The correct option is C Pulping $\to$ Mixing additives $\to$ Drying $\to$ Finishing

Paper consists of cellulose and lignin fibres. The steps involved in the manufacturing of paper are:

1. Pulping- It involves the soaking of small pieces of wood in chemicals, which leads to the formation of pulp.

2. Mixing additives- The pulp formed contains some fibrous materials, which is removed during this process. Dyes are added to this mixture to give colour to the paper.

3. Drying- The mixture is pressed by passing it through the rollers and then dried.

4. Finishing- Finally, the dried papers are rolled on the reels.
