LY-YG139D Yarn Evenness Tester

Uses: Evenness Tester is a kind of universal high-performance textile lab instrument. It is used for testing yarn unevenness and hairiness variety, which is suitable for cotton, wool, silk, flax, chemical short fiber spinning and blended yarn. It is very important to improve and guarantee yarn quality.

Characteristics:

1. Capacitive and photoelectric detection are used simultaneously, and the unevenness of line density and appearance are measured at the same time.

2. The unevenness of fine yarn, coarse yarn and sliver can be measured.

3. Advanced drive technology is adopted to achieve 800m/min high-speed testing.

4. The detection sensor automatically moves and changes slots according to the fineness of the measured yarn, and the detection result is more accurate.

5. Fully automatic measurement, automatic yarn drawing, automatic slot change, automatic reciprocating rollers, automatic yarn pushing and zeroing, automatic average adjustment, more convenient operation and higher efficiency.

6. Real-time measurement of CVm%, Um%, H, SH, D, CVD% and defect values ​​of each gear; provide unevenness curve diagram, spectrum diagram, variation-length curve, line density frequency distribution diagram, offset rate-threshold diagram of sliver.

7. The expert analysis system can evaluate the yarn quality level, automatically diagnose and analyze each process, and provide users with process and equipment failure analysis results.

8. The uneven curve can be saved and replayed, and the defect position can be marked on the uneven curve.

9. Automatic alarm when the yarn is broken during the test.

10. Powerful statistical analysis function, providing annual and monthly product quality level analysis graphics and quality trend charts to provide a basis for scientific management for users. The graphical interface is used to cooperate with the detection extension panel buttons to complete the test with one button. Equipped with a three-dimensional fabric simulation system, it automatically draws yarn contours, electronic blackboards, and woven fabric and knitted fabric renderings, and the fabric structure can be set arbitrarily.
