how are trees transformed into paper?

Question

i am very intrested in how trees can be transformed into a bunh of paper can you help me?

Answer 1

Some paper is made brand-new from trees - either small trees harvested just for that purpose, or from sawmill scraps left over when larger trees are made into lumber. A second source of papermaking material is recycled fiber. Each year, more and more paper is recycled - its fibers used a second, third or fourth time. Every year, about 50% of the paper Americans use is recovered for recycling and other uses.

Almost all of the paper you use today is made of wood fibers. Some specialty papers, like stationery and money, are made from linen, cotton, or other plants. Other papers contain a combination of cellulose fibers and synthetics such as latex. Still others are made completely from synthetic materials such as polyolefine. You might find latex in a waterproof mariner's chart, or polyolefine in a rugged courier envelope. But you'll find natural fiber paper almost everywhere!

Answer 2

First, workers harvest trees, mostly from special tree-growing areas called tree farms. After the trees are removed, more trees are planted in their place.

The logs are transported to the paper company where they get a bath to rinse away dirt and other impurities before being turned into small chips of wood.

The chips are then sorted according to size, and moved to the pulping operation, where they will be turned into pulp for making paper.

In the pulping stage, the individual wood fibers in the chips must be separated from one another. This can be accomplished using one or more pulping techniques. The type of paper that's being made determines the pulping process that is used. The finished pulp looks like a mushy, watery solution. But if you look at it under a microscope, you will see that the individual wood fibers have all been separated.

Now it's time to make paper out of our pulp. That mainly means getting the water out of the wood-fiber soup, since this papermaking stock is about 99% water. The first area in which this takes place is called the wet end of the papermaking machine.

First, papermakers spray the stock onto a long, wide screen, called a wire. Immediately, water begins to drain out the bottom of the wire. This water is collected so that it can be reused over and over again. Meanwhile, the pulp fibers are caught on the top side of the wire, and begin to bond together in a very thin mat. The fiber mat remaining on the wire is then squeezed between felt-covered press rollers to absorb more of the water.

Even when this wet end work is over, the pulpy stuff on the wire is still about 60% water. But now it's time for the dry end.

In the dry end, huge metal cylinders are heated by filling them with steam. The wet paper, which can be up to 30 feet wide, passes through these hot rollers - sometimes dozens of them, and often in three to five groups. Heating and drying the wet sheet seals the fibers closer and closer together, turning them gradually from pulp into paper.

When you look at a piece of paper, can you find any difference in thickness in that single sheet? Probably not, thanks to a part of the paper machine called the calender - big, heavy cast iron rollers that press the drying paper smooth and uniform in thickness.

Sometimes the paper is coated, often with fine clay, to make it glossier and easier to print on.

A bit more drying, then rolled onto a big spool or reel, the pulp - a miraculous mat of fibers from trees - has become paper, ready for a thousand uses.

Answer 4

Trees are felled,stripped of foilage and bark,cut into fine chips and mixed with water until you get a consistancy of mix like porridge.This mix is then placed in thin mesh frames and pressed to release all the water.The resulting sheets of wood (which has now become paper) is dried creating sheets of paper.

Answer 5

Wood is mashed into very small pieces then soaked in water to make wood pulp it is then tipped onto a press and squashed flat dried out and you have paper.

Answer 6

basicaly they crush the tree up and mix with water turns into pulp then roll flat and let dry hey presto paper...

Answer 7

I think that they take the wood, turn it into sawdust, turn the sawdust into pulp by getting it wet, and press the pulp into the paper.

Answer 8

cut and then fined down thin enough to be paper then finer for newspaper

Answer 9

Wood elves and Weyerhouser formed an alliance.
