  • Comparing the absorption volume of test pieces immersed over time in room temperature moisture with weight, WF absorbed about 40% more than PLAIN, and PLAIN stopped absorbing after 10 minutes, but WF continued to absorb. It is thought that the woven fabric layer of the core material continued to absorb moisture. In the heat transfer test, the test piece to which only WF was applied had a temperature difference of about 2℃ compared to PLAIN, and when the insulating liquid was sprayed, there was a difference in heat transfer properties of up to 5℃. This is judged to have low heat transfer properties of the basic woven fabric, but the heat insulating liquid also further reduces heat transfer properties.

  • A comparative analysis of wear resistance and shock resistance tests shows that wear resistance is up to 6 times and at least 2 times higher wear resistance than current products, even considering the limited number of turns due to too much rotation. In the case of shock resistance, there was no problem except 7.5T, but this is only a result of KS test method, so it is deemed that additional fall impact tests by various objects in daily life are needed for practical comparison.
