Constant Tension Transport (CTT)
INTRODUCTION
The CTT is a versatile dynamic test instrument that is available as a mini textile laboratory. With its easy to change test attachments, the CTT is the only lab instrument that offers more than 10 yarn tests on the same instrument. This versatility along with its dynamic test principle, the CTT offers every fiber and yarn user the ability to eliminate the high cost of running trials on production instrument.
Operation
Applies and maintains tension between 2-700g at test speeds 20-360m/min. This provides variety of production trial conditions to check yarn performance beforehand.
Versatility
With interchangeable test attachments, the CTT is the only lab instrument that offers more than 10 yarn tests on the same instrument. Its unique design provides the ability to test natural and synthetic yarns as well as high performance and technical yarns, including carbon, glass or hybrid yarns, which cannot be tested with conventional capacitive based systems.
Dynamic Testing
CTT dynamic test principle allows every section of the yarn to be tested under constant tension and speed conditions. This provides the closest conditions to the actual production that the yarn has to experience.
End-users
All types of Natural and Synthetic yarn producers and buyers, including cotton yarn, Polyester yarns, Nylon yarns, the blend yarns, flax and jute yarns, elastomeric covered yarns, wool and acrylic yarns, rayon and viscose yarns, silk yarns, carbon and carbon-glass hybrid yarns, and many others.
FEATURES
- Dynamic yarn test instrument that performs as a mini yarn textile laboratory
- Ability to run the more than 11 different yarn quality control tests on the same machine
