What is Paper Made out of Chemically, and How is it Made??

What is paper made of chemically? We use it every day around the world in a lot of different ways. Our money is made out of paper. We use paper to write or draw on. We print stuff onto paper. We use it in the bathroom and kitchen. Paper is everywhere, but how is it made?

Cellulose, Hemicellulose, and Lignin

Most types of paper follow the same basic ingredients: cellulose, hemicellulose, lignin, and some type of filler like china clay. Now that we know the names of what paper is made of chemeically, what exactly are they, and how do they work to make what we know as paper? Cellulose is the main component of a plant's cell wall. This is what gives plants their structure. Cellulose is also what makes up algae. Cellulose is described as being stringy and fibrous.

Hemicellulose surrounds cellulose fibers in a plant's cells. It is made up of complex carbohydrates and consists of xylans, a uronic acid, and arabinase. Xylans and arabinase are what are known as 5-carbon sugars, and uronic acid is a sugar acid. Lignin comes second to cellulose. It is also responsible for the structure and rigidity of plants just like cellulose is. Lignin is the most prevalent in the wood in trees.

Fillers, Starch, and Rosin

There are a few different things that can be used as a filler in the making of paper. The first thing is china clay. China clay is defined by Collins dictionary as, "a fine white clay used for the manufacture of hard-paste porcelain and bone china and in medicine as a poultice and gastrointestinal absorbent (collinsdictionary.com). Another filler that is used is titanium dioxide. Titanium dioxide is a white solid that is insoluble that is used for white pigment.

Calcium carbonate is another thing that is used as a filler. Calcium carbonate is an insoluble solid. It occurs in calcite, chalk, marble, limestone, stony coral, and the shells of mollusks. Some type of paper also use starch and rosin. Starch is defined as an insoluble white, organic chemical that is used by plants as stored energy. Rosin comes from a sticky substance from trees and other plants. This is called resin. The resin is turned into a more solid form which is called rosin.

Components of Different Types of Paper

Different types of paper are made up of different levels of these components. Copying paper is made up of cellulose, hemicellulose, China clay, and calcium carbonate. Newsprint is made of cellulose, hemicellulose, and modified lignin. Box paper is made up of cellulose, hemicellulose, and lignin. Currency paper, money, is made completely of cellulose.

The Process in which Paper is Made

Now that we know the answer to the question: what is paper made of chemically, let's dive into how paper is made. The first step to making paper is making the pulp. The bark is removed from logs through the process of being tumbled inside a drum. The logs are then moved to grinders. The grinders crush the logs between plans that are spinning to make them into a pulp. After the pulp is formed, filters are used to purify it.

Next, comes the process of beating. The pulp is put into a bug tub with machine beaters. This is the step where the fillers are added to the pulp. The pulp is then squeezed and pounded through a process called beating. This is where sizings are also introduced.

Now comes the transformation from pulp to paper. Rollers compress the pulp, while suction mechanisms drain the water under the belt. If the paper requires watermarking, this is when it occurs. A device called a dandy moves across the paper, and a design is pressed into the paper. A big machine that has up to 70 drying cylinders is used to remove the rest of the water. The paper is then passed through metal rollers called calendars to compress it even more. The paper is finally coiled into huge reels and further processed for the intended use.
