Question

Explain the process of paper -Making in your own words​

Answer 1

Explanation:

Simply put, we use trees to make paper. Every part of a tree is used in the production process of creating paper.

Here are the five steps to make paper from trees:

Step One: The tree is broken down

Cellulose fibers are extracted from a variety of sources and converted to pulp. Most trees are churned out quickly, efficiently, and automatically by gigantic machines.

Step Two: Processed

Pulp is combined with water and placed on a paper making machine where it is flattened, dried, and cut into sheets and rolls.

Pulp is prepared for papermaking machines, either mechanically or chemically. The mechanical method (generally used to make lower-grades of paper) is called the groundwood process because the pulp was made initially by using huge stones to grind up logs. Nowadays, pulp is prepared by giant machines that cut, wash, chop, beat, and blend wood, rags, or other raw materials into a soggy mass of fibers. In the chemical method, known as the Kraft process (from the German word for “strength,” because it produces strong paper), plant materials are boiled up in strong alkalis such as sodium sulfide or sodium hydroxide to produce fibers.

Step Three: Bleaching

At this point, loading materials (surface coatings such as clays), dyes (to make colored paper), and sizes (to strengthen and waterproof and prevent inks from spreading) can be added to the mixture to change the properties of the finished paper (sometimes they’re added later).

Step Four: Produced

Now a manufacturer produces it into their product which could be construction paper, corrugated boxes, cover stock paper, envelopes, paper bags, wrapping paper, newsprint, books, recycled paper, specialty grades of paper, tissue paper, wallboard and numerous other products.

Step Five: Packaged

Next, the paper item is packaged and is sold in stores and online.

Answer 2

Answer:

Logs of wood are made to pass through a debarker, where the barks of the tree are separated. ... The pulp is made to travel down the screen to remove the excess of water and then to the rollers where it is being dried and squeezed between large rollers to form rolls of paper.
