laboratory. The installation is designed lately by means of new technology. It can be used to test linear density unevenness and corresponding structural character of yarns, roving, slivers which are spun with cotton, wool, flax and short synthetic fiber. It is very important for quality assurance of yarns in textile industry.

Main features
The yarns draft system takes advantage of Panasonic AC Servo system. The host uses Pentium processor, monitoring programme runs on the windows 98 platform, operating conveniently. The installation has been equipped with the yarn expert analyzing and diagnosing system which can analyze level of 1 value and CV value, and judges status of textile device in term of spectrogram, finds where the devices are out of order or have faults. Compact structure, novel shape, complete functions, high reliability, a great deal of output information and a high ratio between performance and cost.
