PAPER MAKING PROCESS
The art, science, and technology of trade marks the procedures, apparatus, and substances want to build paper and cardboard, these getting used wide for printing, writing, and packaging, among many other purposes and useful products.

In this article we will learn about Paper making process.
HOW PAPER IS MADE?
Pulp and paper mills area unit extremely complicated and mix many various procedure regions that contains of wood preparation, pulping, chemical recovery, bleaching, and papermaking to convert wood to the final product.
Processing possibilities and the type of wood processed are frequently purposive by the final product.
The pulp for papermaking may be manufactured from virgin fiber by chemical or mechanical ways or may be made by the repulsing of paper for recycling. Wood is the most original raw substance. Paper for recycling accounts for about 50 % of the fibers used – but in a few cases straw, hemp, grass, cotton and other cellulose-bearing substance can be used.
Paper production is basically a two-step process in which a fibrous raw material is first changed into pulp, and then the pulp is transformed into paper. The harvested wood is first processed so that the fibers are separated from the non-practical fragment of the wood, the lignin.
Pulp making can be done mechanically or chemically. The pulp is then bleached and further processed, depending on the type and grade of paper that is to be manufactured. In the paper factory, the pulp is dried and pressed to make paper sheets.
Post-use, Associate in nursing increasing fraction of paper and paper product is recycled.
Non recycled paper is either landfilled or burnt.
WHAT WAS USED BEFORE PAPER?
Many writing materials were made, before the invention of paper.
Following are the materials which were used before the paper:
The Romans wrote on waxed tablets with a pointed stylus; this was famous for temporary notes and messages.
The later invention of paper by the Chinese was an enormous success.
CHINESE PAPER MAKING
Paper and printing were one of the most important inventions of Chinese, which changed the world. Paper was manufactured in 100CE. The very first paper was produced from rags, but after some time plant materials such as bamboo, bark and hemp were used.
PAPER MAKING IN KOREA
The known examples of paper making in Korea is from the 6th century. In Korea, early paper was made from a pulp comprising of fibers from hemp, mulberry, rattan, bamboo, rice straw, and seaweed.
PAPER MAKING IN JAPAN
According to the culture, paper making was introduced to Japan by a Korean Buddhist monk named Don-Cho, who instructed paper making at the Imperial Palace in the year 610 AD. At that time, Buddhism was still a new religion in Japan, having been first introduced some 60 years earlier.
PAPER MAKING IN EGYPT
Just like the Chinese, the Arabs of Samarkand aimed to keep the know-how of paper making process a secret, but the practice did increased to Egypt during the early 900s. Egypt already had its own very long culture of writing on something that was quite similar to paper – papyrus. Papyrus is produced from the essence of the papyrus plant. The earliest archeological evidence of papyrus is remains dated from circa 2555 BC.
PAPER MAKING IN SPAIN
By 1150 AD, paper was present in Spain, having been brought there as a result of the crusades.
Soon, the primary European paper trade had been established in European country.
WHY SAVING PAPER IS NECESSARY?
Paper should be saved because it takes around seventeen full grown trees to make one ton of paper.
Trees, as we know, area unit necessary to keep up a balance of nature.
Therefore,’ in order to save trees and prevent the effect of their loss on living organisms, we need to save paper.
Ways by which paper can be saved:
- Collect used paper and recycles it.
- Use both sides of a paper for writing.
- Spread awareness about the importance of paper.
- Use paper intelligently.
