Transcript of The Chemistry of Hair ties

The Making of Hair Ties Many uses are found with hair ties. The average girl wears a hair tie on her wrist at all times. A hair tie: is a device used
to fasten hair, particularly
long hair, into a hairstyle
(usually a ponytail). Two kinds
of hair tie are the scrunchie
and the hairpin. Hair ties
are useful in securing one's
hair back to keep it away
from the face. Hair ties are made of elastic, making them have the same properties as rubber bands. Hair ties also have
many creative uses The rubber band was patented in England on March 17, 1845 by Stephen Perry. Like plastic, rubber is a polymer (a chain of repeating units called monomers). In rubber, the monomer is a carbon compound called isoprene that has two double carbon heads. This is the the same thing in tree sap.
The process continues until you have many thin strands of isoprene molecules linked like a chain. The attraction between these strands holds the rubber fibers together and allows them to stretch and recover. Chemicals in hair ties (rubber): Carbon black Neoprene (Chloroprene) EPDM (Ethelyne, propylene,
diene; ethelyne, propylene) Nitrile
butadiene Polysiloxane Stryrene butadiene Isobutene isoprene Isoprene (natural & synthetic) Chloro-sulfonyl-polyethylene Acrylate-butadiene
copolymer of
acrylic ester
and acrylic halide Polyethylene-apdate,
Poly (oxy-1, 4, butylene)
ether Chlorinated- polyethylene Hexaflouropropylene-
vinylidene flouride Polybutadiene Tetraflouroethylene- flouronitrosomethane- perflourobutyric acid Polychloromethyl oxirane Ethylene oxide and chloromethyl oxirane Flourocarbon People who Hair tie bussinesses are included
in larger Hair ties don't just have
a hair company made strictly
for them. Companies like
Goody and Scunchi have multiple
hair accessories, such as
headbands and clips. These products are made in large factories. Hair ties don't have their own
companies that are strictly only
hair ties. The companies Goody
Scunci have many others. To work for the industry
of hair ties, you would need
to be a factory worker. Factory workers make an average
of 50 to 60 thousand dollars a year!
The business is in high demand and
a lot of people are dependent on it. It's very simple to become a factory worker. Most factories accept you after you graduate high school. Some factory workers have a B.A.(bachelor of art) degree in agricultural Engineering. The duties of a factory worker
are ordinary jobs. There's not
a lot of hard labor and it's mainly
running machines and looking over
the process and making sure if
everything goes right. It's a simple,
yet important job. -Dumping material into hoppers of machines
-Stopping moulding machines and discharging contents
Cutting foam products from foam blocks
-Cleaning, smoothing and waxing moulds for making products
-Brushing and spraying release agents onto moulds to assist with the removal of moulded products
-Building up layers of fibreglass and resin on moulds
-Cleaning work areas, tools and equipment
may smooth rough edges of moulds using files, grinders and sanders More Duties of Factory Workers Factory workers have very steady
jobs that are almost garuanted
to be your job for a lifetime.
Factory workers are necessary but
not in demand. Hair ties have no chemical effects or reactions. The only issue is that they can get tangled or stuck in your hair. Their physical properties are alwas round and stretchy. They are easy to be lost but are always around. Imagine what people did
before hair ties...
Ah! Think about it! If you don't work for
hair ties, you use them. Or a lot of people you know do. :)
