Advanced Fiber Crimp Testing Technology
VIBROTEX 400 offers thorough analysis of the crimp properties of single fibers for production quality control, research and development as well as for educational purposes. This laboratory instrument provides determination of the crimp properties of staple fiber including crimp stability, removing/recovering crimp and crimp regularity of staple fiber.
Proven Technology and Experience
The applied technology is based on many years of research conducted within Lenzing AG, with more than two decades of experience matched with excellence in mechanics and latest processor technology. VIBROTEX 400 meets all requirements of fiber producers for accurate, flexible and thorough analysis of the crimp characteristics of staple fiber.
Quick and Reliable Results
Test results are available within seconds for quick reactions to quality levels and possible deviations from set quality levels. Results are represented graphically as well as in terms of figures on the connected PC, enabling immediate feedback for production quality control.
Sophisticated Test Method
Electromagnetic clamps fix the pre-tensioned fiber at top and bottom. The fiber is automatically drawn to carefully remove the crimp to a predefined extent. After the fiber has been straightened to the predefined trip level, the bottom clamp changes direction towards relaxation of the fiber. The applied algorithm allows for extrapolation up to the standard crimp removal of 1 cN/tex. For handling purposes, pretension is accomplished by means of paper weights, preventing the crimp properties from being affected by the pretensioning.
