Description Of The Study

Zipper:
A zipper, zip, fly, dingy, or zip fastener, formerly
known as a clasp locker, is a commonly used
device for binding the edges of an opening of
fabric or other flexible material, such as on a
garment or a bag. It is used in clothing, luggage
and other bags, sporting goods, camping gear,
and other items.

History
The story begins when Elias Howe, Jr. (1819–1867), inventor of
the sewing machine, who received a patent in 1851 for an
"Automatic, Continuous Clothing Closure." It didn't go much
further beyond that, though. Perhaps it was the success of the
sewing machine, that caused Elias not to pursue marketing his
clothing closure system. As a result, Howe missed his chance to
become the recognized "Father of the Zip."
Forty-four years later, inventor Whitcomb Judson (1846–1909)
marketed a "Clasp Locker" device similar to system described in
the 1851 Howe patent. Being first to market, Whitcomb got credit
for being the "inventor of the zipper." However, his 1893 patent
did not use the word zipper.
The Chicago inventor's "Clasp Locker" was a complicated hook-
and-eye shoe fastener. Together with businessman Colonel Lewis
Walker, Whitcomb launched the Universal Fastener Company to
manufacture the new device. The clasp locker debuted at the 1893
Chicago World's Fair and was met with little commercial success.

Components Of Zipper:

Locking Mechanism

The zipper works by an elastic, that is, reversible, deformation of the
"locking members" (teeth). The zipper teeth are shaped and sized so
that the forces which act on the zipper when the garment it is sewn on
is worn cannot unlock the teeth.

Applications Of Zipper:
A fly front style is the most common zipper application used for
bottoms, especially on skirts and trousers. It is actually the
only application used on denim jeans both for men and women.
Traditional, fly front styles are mostly found on men's trousers as
opposed to womens.

Importance Of Zipper

It has played a significant role in the
development of new technologies in the
20
th
century, including Velcro, the plastic zipper,
and resalable bags. The zipper not only makes it
more convenient to fasten clothing, but
plastic zippers are also wind, dust and
waterproof, and don't snag, stick or rust.
The zipper is really handy. It has changed the
world in many ways. ... It opened jobs for people
who specialized in sewing the zippers on to
clothing and making the zippers so people could
sew them on. Sadly, once machenies were made
to preform these procedures these people lost
their jobs.

Conclusion:
The zipper not only makes it more convenient to
fasten clothing, but plastic zippers are also wind, dust
and waterproof, and don't snag, stick or rust. The
invention of plastic zippers also meant they could be
created in any color, making then another tool in the
fashion designers arsenal. Zipper is a minor item in
dressing industry but it has its great importance in
this field. We can't use buttons everywhere on our
pants, trousers.
