The History of Paper
The
word "paper" comes from the word "papyrus", but papyrus itself
is not actually paper, but its predecessor. Papyrus was used
by the ancient Egyptians and made by a process generally known
as "tapa", the technique which involves beating or pressing
and was used extensively in cultures lying near the Equator
and is still practiced today in sparse locations in the Himalayas
and in Southeast Asia. The technique used bast, which is a
kind of strong fiber with properties similar to flax. The
bast is softened by a cooking process, and then is beaten
and flattened into a thin fibrous sheet. This sheet is then
dissolved in water to form a water-pulp mixture. This mixture
is then poured into a wooden frame with a fabric bottom. This
is put into a large amount of water, and the resulting water-pulp
mixture is spread by hand. The water is then allowed to drain
from the frame and then the frame is set by a fire to dry.
When the frame(and what is now paper-like material) is dry,
the paper-like sheet can now be pulled from the frame and
used. This process, while ingenious for its time, had some
problems. Bast was not widely available to everyone, and even
if it was, the amount was not enough to make a good sheet
of papyrus. Soon substitutes, such as hemp and flax, which
were normally used for making textiles, ended up being used.
The other problem was the fact that one could not make another
sheet of papyrus until the paper-like sheet last used was
dry and peeled off the frame. An increase in production, such
as using multiple frames, would create a shortage of an already
scarce raw material.
Paper Is Invented
Although it is not historically
known which person invented paper, legend has it that paper
was invented in 105 A.D. by a Chinese eunuch(other versions
of the story say he was an Imperial Court official) named
Ts'ai Lun. Archeologial records, however, indicate that paper
was available as far back as 200 years earlier. Nevertheless,
the Chinese are credited for inventing what we now know as
paper. Not only did they invent it, they also improved upon
it, using starch as a sizing material and adding a yellow
dye in order to stave off insects. They used coarsely woven
cloth set in bamboo frames, and later they improved the papermaking
process by developing a smooth covering for the paper making
mold, allowing the mold to immediately be used after a sheet
has been formed and not having to wait until the frame is
dry. Papermaking went through a series of refinement periods
in China:
Early Period(206 B.C.-220 A.D.)
[West Ham Dynasty to East Han Dynasty]
In this period, paper is
not yet popular. Silk is available and silk paper as
well as paper made of hemp is invented at this time,
which are produced from fabric scraps.
|
Development Period(265-581
A.D.)
[West Jin Dynasty to Sui Dynasty]
This period marks the time
when paper becomes much more popular, surpassing silk
and bamboo as the preferred medium for writing and artwork.
|
Leap Period(618-1279 A.D.)
[Tang and Song Dynasty]
In this period, papermaking
advanced to the point where different paper types could
be made available to artists. These different paper
types included hemp paper, hide paper, bamboo paper,
and xuan paper. Xuan paper was special, in particular,
in the fact that it had a very smooth, white surface,
which was perfect for use in artwork and calligraphy.
|
Peak Period(1271-1911 A.D.)
[Yuan, Ming & Qing Dynasties]
This period marks centuries
of constant improvement in the technology of papermaking.
In this era, the Chinese art of making paper is at its
highest. The period of Shuen-De(1426-1436) in the Ming
Dynasty, in particular, produced some of the finest
quality paper for artwork, being made from Sa-Tan rice
straw and Qin-tan bush fibers, which was highly prized
among artists of the time. By the end of this era, the
art of papermaking had spread thruought the world.

Papermaking remained a Chinese technological
secret for centuries until it finally spread to Korea, Japan,
and the Middle East through trade routes. Soon, paper replaced
papyrus as the main writing medium. The Chinese also spread
their knowlege of papermaking to Tibet, where paper replaced
traditional writing material there. The original, narrow palm-leaf
books still influences the shape of Tibetan books today.
Paper Spreads to Europe
The
first paper mills were built in Italy and Spain in the 11th
Century and Johann Gutenberg's invention of the printing press
increased the demand for paper(and knowlege) tremendously.
By 1500 almost 500,000 books were printed. One of the first
books printed, Johann Gutenberg's 42-line Bible, used paper
that has never been excelled for durability and the printing
of the Bible is seen as a major turning point in printing
history. The Italians provided further advancements in the
papermaking process, including the use of water power. Pulp
in the West was originally created from a variety of sources,
including old clothes and cotton, but it was soon discovered
that paper could be made from hundreds of different cellulose
and other fibers, including mulberry, straw, banana, sugar
cane, rice, and corn stalk. Paper can be made to have a very
short life-span, such as modern newsprint in use today, or
can be made to last hundreds or even thousands of
years.
Wood Is Finally Used To Make Paper
The
need for paper greatly increased during the Industrial Revolution,
and materials that were usually exploited to make paper became
scarce. During the American Civil War, rags and cotton became
rare as the uses for these materials went to the War efforts,
such as bandages, uniforms, etc. This critical shortage provided
an impetus for finding more materials that paper could be
made from, and made easily. An extremely wide variety of materials
were tested, including, believe it or not, cow excrement!
From about 1840 to 1890, the little amount of rags available
were mixed with straw to help provide for the need of paper.
Wood was finally first used to make pulp for paper production
in 1872, only 130 years ago. The printers of the time at first
would have nothing to do with it, and as a result, the first
wood pulp mills went out of buisness. After some time, a desperate
paper mill in New England finally shipped paper made from
wood and rag pulp, but however claimed it was made from rags
and straw. It was found to work well in presses, dispelling
the printers' worries. Paper made from wood increased in popularity
during the early 1900's until it became by far the main type
of paper in use and still remains in use today.
Papermaking in the 20th Century
Science
and knowlege in the 20th Century grew faster than any century
before-hand. From the advancements in chemistry and physics
with quantum mechanics and Relativity to the advent of commercial
airlines, computers, and space-flight, mankind has expanded
its knowlege of how to do things, and do them better. Papermaking
has not been left in the dust. In the last 20 years, papermaking
has been advanced through the use, among others, of thermomechanical
pulp, development of new paper grades, such as light weight
coated(LWC) paper, new sheet forming processes, new fillers,
chemical dyes, de-inked recovered paper, and, most of all,
automation of the papermaking process. There has also been
increased awareness in the ecological effects of papermaking,
and much has been done to increase recycling efforts and to
prevent the papermaking process from harming the environment.
The Future of Paper
With
the advent of the Internet, there were many people who believed
that paper would be made obsolete as literature becomes available
online. Of course, this turned out not to be true. But what
about the future? Will paper have a role in an age increasingly
ruled by computers, pagers, e-mail and webpages? The answer,
most definately, is a resounding yes. While there
have been many advances in the digital realm, and companies
such as E-Ink are making
progress toward making paper act more like a digital device
and interface into computers, things still can go wrong. Hard
drives and floppy disks can still become corrupted, CDs can
become scratched, and computers can fail for any number of
reasons and they, of course, require electricity to operate.
Paper, however, will probably play an increasing role in the
computer and hardware industries, as it will become a more
viable option to actually print circuts onto paper,
making future laptops much more versatile than the ones today
and making phones made out of paper possible. Despite all
the technology available to mankind, for the forseeable future,
paper, an invention that is almost a thousand years old, is
still the most viable and convenient option for storing data
that can survive generations of use without wearing out.
