write a paragraph within 100 words on how to make paper
Answers
Answer:PROCESSING OF PAPER
PAPER IS ESSENTIAL FOR OUR DAILYLIFE.IT IS NEEDED BY EVERYONE. TO PREPARE PAPER THE FOLLOWING STEPS NEEDS TO BE TAKEN.
AT FIRST SOME BAMBOOS ARE CUT DOWN FROM BAMBOO WOOD. THEN PULP IS MADE WITH BAMBOO PROPERLY.NEXT SOME CHEMICALS ARE ADDDED TO MAKE IT SOFT AND QUALIFIE. AFTER THAT THE CHEMICAL ADDED PULPS ARE ROLLED INTO SHEETS THROUGH MACHINE. NEXT REQUIRED AFTER OF COLOURS ARE ADDED INTO THE SHEETS TO MAKE IT COLORFUL. THERE AFTER THE SHEETS ARE DRIED PROPERLY THROUGH THE ELECTRIC DRYER MACHINE.FINALLY PAPER IS READY FOR USE.
Answer:
Most paper is made from forestry products, usually trees. The most common of trees that paper comes from are:
Spruce
Pine
Fir
Larch
Hemlock
Eucalyptus
Aspen
Birch
In most cases, the best parts of these trees are used for construction, and less desirable portions are used in pulp.
Cotton & Other Natural Fibers
Natural fibers such as cotton are used in some cases because its fibers are very strong. This makes it an excellent choice for documents that may need to be archived. This strength, combined with its unique feel is why cotton paper is popular for letterhead and other corporate stationary products.
Recycled Fibers
Many papers include different types of recycled content. These include:
Pre Consumer Waste (paper waste from the paper manufacturing and printing processes)
Post Consumer Waste (paper waste that has already touched a consumer, like a recycled newspaper)
Sawdust
How is Paper Pulp Made?

Although many fibers were mentioned above, forestry products (logs from trees) are the source of most fiber in paper pulp. There are three main components, which must all be separated to make pulp.
Bark
Fiber
Lignin
The bark protects the fibers of the log, which are held together by lignin. The goal is to extract the fibers, and this is accomplished either using a chemical or mechanical process.
Paper mills all work a little bit differently, so please keep in mind that these are generalizations
What is Mechanical Pulp?
Since most paper starts as logs, there is a significant amount of bark. Bark does not work well for making paper, so the first step in the mechanical pulping process is to remove the bark from the logs. This excess material becomes a biomass energy source to help power the paper mill.
In most processes, the logs are ground up using a giant machine containing a rotating disk and a fixed steel plate. Usually, heat and chemicals are used to aid in this process.
