CTT-E Constant Tension Tester Electronic Drive, All-in-one Dynamic Yarn Tester

Constant Tension Transport with Electronic Servo Drive (CTT-E) is a dynamic test instrument that is available as a mini laboratory for yarns.  With its interchangeable test modules, the CTT-E can run more than 10 tests on the same instrument for all natural and synthetic yarns as well as technical yarns such as aramids, carbon, glassfiber and spandex. With this versatility along with its dynamic test principle that will test every section of the yarn, the CTT-E offers the ability to eliminate high cost of running trials on actual production machines before the yarn is sent to the next textile process.

Electronic Servo Drive and Tension Arm System that maintain 2g-700g constant input tension at test speeds between 20-500m/min

Offers dynamic test conditions that tests every section of yarn to predict yarn behavior and avoid high cost of running trials on production machines

Easy to install test modules that allow measurement from coefficient of friction, entanglement count to yarn appearance on the same instrument

Four Tension Arms with different max tension and sensitivity ranges

Available with Standard (1000g) and Spandex Range (100g) tension measurement heads

Applicable for all types of natural and synthetic yarns, including cotton, polyester, nylon, wool, silk, acrylic, flax, viscose, carpet yarns

Functional tests for technical yarns such as aramids, carbon, spandex, glassfiber and monofilament
