Abrasion Resistance
The Bottom Line
Nylon, KVX200™, HDPE and HTPP all test out about the
same. PE does slightly worse, but not much.
Question: Why do some companies
claim that nylon holds up better to abrasion?
Answer: Certain test methods can
can be misleading.
Explanation
When considering abrasion resistance, the method used to
test is crucial. By altering the test method, it's easy to misrepresent
the real world performance.
How?
Nylon has a higher melting point than many polymer fibers.
So, by incorporating a testing method that generates friction heat, its
easy to make nylon look dramatically better, even though it isn't.
Here is how you do it:
When testing resistance to abrasion simply rub the same
spot until the friction generates enough heat to melt the fibers. Since
nylon has a higher melting point, it will appear that nylon holds up
better to abrasion. In fact however, by testing in this manner,
abrasion resistance isn't measured at all. By generating friction induced
heat, only the melting point is measured.
Why are these tests invalid?
These tests are completely invalid because in real world
use, friction never generates enough heat to melt the fibers. Absolutely
never. After a ball strikes the net, the temperature of the netting "does
not appreciably change at all". In other words, no heat is generated from
friction in "real word" use.
Visualize how a batting cage works. When a ball strikes
the net, the temperature increase cannot even be measured. Even
if it could be measured, before that ball even hits the ground any
potential friction heat would be completely dispersed and gone.
What this means:
Claims such as "30% more abrasion resistance" fail to
mention that only the melting point is being test, not actual resistance
to "real world abrasion"
