Automatic Yarn Evenness Tester

Automatic Yarn Evenness Tester

Integrate multiple yarn sensors in one device(automatic yarn evenness tester) to measure yarn unevenness, uneven diameter, uneven density, hairiness distribution, and provide spectrograms, variation-length curves and other graphics.

The unique CV-L curve analysis software of automatic yarn evenness tester can quantitatively analyze the non-periodic unevenness of the yarn and can be traced back to the production process.

The unevenness curve can be saved and scaled, and the defect position can be marked on the unevenness curve.

The expert analysis system can evaluate the yarn quality level, allowing users to more accurately and effectively analyze the textile process and equipment failures.

When measuring the number of hairiness roots, the projection counting method is used to achieve high-speed testing of the number of hairiness roots, which is in line with international standards and ensures that the finished yarn meets the higher needs of end customers.

Powerful statistical analysis function, providing annual and monthly product quality level analysis graphics and quality trend charts, providing a basis for scientific management for users.

Adopting advanced drive technology to achieve 800m/min high-speed testing.

Automatic selection of detection slots, more accurate detection results.

Automatic roller movement to extend roller service life.

The unique density unevenness detection p of automatic yarn evenness tester provides a means for analyzing yarn weak twist and strong weak rings.

Optional slub yarn function, and can provide stable and detailed quality analysis for irregular slub yarn problems.

Optional yarn defect grading function.

Optional fabric simulation function.

Efficient testing, "one machine is equivalent to two machines".

Two varieties can be automatically tested at one time.

Patented technology: Yarn random unevenness expert analysis system; Patent number: 2015103917498; Yarn random unevenness expert analysis system can quantitatively analyze the random unevenness of each segment of the yarn by analyzing the CV-L curve; Predicting the quality of the fabric: guiding users to optimize the production process and improve the quality of the fabric; Defect distribution expert analysis system; By quantitatively analyzing the yarn density distribution, the yarn defect distribution can be quantitatively analyzed, and the fabric quality can be predicted, especially the distribution of long thick sections and long thin sections.

Abnormal data can be re-tested at the original position.

Unique roller anti-tangling device.
