Test methods explanation
We have tested 5 fiber samples using two solutions to test fiber fineness and tenacity: Solution 1 and solution 2.
Solution 1
We use YG002C measured the fiber diameter, and YG005S tested the break force and extension. The fiber density is converted to denier from diameter using the formula. Then use the break force divide the density to get the tenacity. Please move to TABLE 1 to view the test result. We have attached YG002C parameter sheet in Appendix 1 and YG005S parameter sheets in Appendix 2.
Solution 2
We use ZK100F measured the fiber density, and YG005X tested the break force, extension, and tenacity. Please move to TABLE 2 to view the test result. We have attached ZK100F parameter sheet in Appendix 3 and YG005X parameter sheet in Appendix 4.
