CTT - DYNAMIC FRICTION TESTER with STICK-SLIP TEST OPTION

LH-402 CTT-DTT

This test measures the Yarn-to-Pin (ceramic or metal), Yarn-to-Yarn or Yarn-to-Hot Pin Friction.

Special finishes or wax is applied on the yarns to reduce friction, wear and static electricity. By applying constant input tension and monitoring the output tension on the yarn, CTT-DTT test measures the Coefficient of Friction, COF. These tests conform to ASTM D 3108 and D3412. The program provides statistics for COF measurements.

As a special option, Stick-Slip test at very slow test speeds is also available. This test will allow you to look for if stick-slip condition is happening during the friction build-up.
