| Advantages
of Yarn : |
| A.
Comfort
|
|
1.
Humidity Transfer
: Polyolefin (polypropylene) doesn’t absorb the water, it
repels the water. It is the only synthetic yarn that shows this
property. Humidity (sweat) gets out from fabric as steam. Fabric
doesn’t stick
to the skin, it allows to breathe. Also it
provides comfort ( sportswear ) |
 |
2.
Thermal Conductivity
: Polyolefin yarn is a synthetic yarn that has the lowest
thermal conductivity. It means that it conserves the heat for
longer time. (Ski cloth, under wear for army).
Polyolefin
( PP ) : 6.00
Cotton
: 17.5
It
means that polyolefin conserves the heat approximately 3 times
more.
|
|
| 3.
Quick Drying :
Drying time of polyolefin is very short. Because it doesn’t
absorb the water. (Swimwear) |
|
| B.
Performance |
|
1. Low Specific Gravity
: Polyolefin yarn is a synthetic yarn that has the lowest
specific gravity. It is %30
lighter than
polyester and %20 lighter than polyamide. Polyolefin gives more
volume and heat with less
weight.
Polyolefin
( PP )
: 0.91
Cotton : 1.54
It
means that you can acquire the
same volume with %69 less yarn. |
|
2.
Light Fastness : Polyolefin yarns are the yarns
that have the highest light fastness.
Colors
don’t lose their properties by sun, water, friction.
3.
Resistant to Smell : Bacterium can not grow in
polyolefin.
Bacterium
produced by sweating can not stay in the
cloth.(Sportswear)
4. Abrasion Resistance :
Abrasion resistance of polyolefin yarns are
high. (Ski cloth)
5. Resistant to Chemicals : Polyolefin yarns are
resistant to chemicals.
( Divingwear,
swimwear). Chlorine can not damage
the fabric.

 |
| Disadvantages
of Yarn : |
|
A. Resistance
to heat of polyolefin yarns are low. Temperature has to
be maximum 80
°C
for all finishing
process. At
120 °C
yarn becomes harder and
loses its shape.
B. PP doesn’t like directly heat contact.
You have to iron at maximum 40 °C.
You have to sell the yarn to
consumer with
label that explaining this property. However there is no
problem for finishing with steam
iron.
C. Polyolefin
cannot be dyed with conventional methods after extruding
. The problem is solved by a very
big range of
our shade catalogue and option of making new colors. |
