Constant Tension Transport (CTT)

Total Concept for Spun Yarn Testing photo

INTRODUCTION

The CTT-BU offers every fiber and yarn producer the ability to eliminate the high cost of running trials on production equipment. The versatile CTT simulates product performance in the testing laboratory, not on the production line where operating costs can increase. The CTT also permits increased testing on each package under dynamic conditions, which can predict the yarn's performance on-line.

Operation

Maintains a pre-selected tension, between 0.5g and 700g, at a selected speed, up to 360 m/min. This function provides the capability to perform different test configurations. It also eliminates the tension variation of the yarn coming off the package.

Versatility

Any measuring head or testing apparatus can be mounted on the basic CTT unit and inserted into the constant tension zone.

Dynamic Testing

Measures every millimeter of yarn at speeds up to 20 km/hour. The basic unit performs two significant tests:

  • A. Dynamic Breaking Strength
  • B. Weak Spot Detection

Endusers

Yarn manufacturers, fiber producers, weavers and knitters.
