CTT - YARN ABRASION TESTER

LH-403 CTT-YAT

The CTT Abrasion test measures the abrasiveness of the yarn while it is running under constant tension at test speeds up to 360m/min.

The yarn abrasiveness can be affected most notably by the fiber shape and the amount of the TiO² on the yarn. If the yarn is really abrasive, the result will be frequent changes of the machine parts such as needles, yarn guides, which in return will increase spare part consumption and overall manufacturing cost.

In this test, the yarn will be running over a standard abrasion wire. When the wire breaks, the test stops. The amount of the yarn that is

required to break the wire is noted and compared with other yarn abrasion test results. In this comparison test, the higher number indicates less abrasive yarn.
