Online Yarn Quality Control Systems
Quality Eye
Quality Eye is the quality control unit for detecting the structural defects of the yarn in twisting and winding machines. These sensors, which can measure up to 100 meters per minute, instantly measure and report the yarn quality.
Quality Eye detects and reports all quality issues such as yarn breakage, thickness variation**, slub, lump**, splice recognition. It can measure the length, thickness, hairiness and tension of the yarn. With its user-friendly operator panel, it can also send a “Stop” command to the machine when necessary.
| Sensor Type | Photo Diode |
| Pixel count | 1 |
| Renovation | None |
| Axis | No axis |
| Dtex value | Immeasurable |
| Sensor signal | Relative change |
| Pollution level | None |
| Yarn speed | Up to 2.500 meters/minute |
Quality Eye uses high-resolution scanning sensors and infrared lights specifically designed for yarns of all colors. With 600 dpi resolution and an 8 mm scanning area, the scanning speed can go up to 1.000 lines per second.
Quality Eye learns the yarn thickness in the first few seconds after starting the machine. Then, it starts measuring percentages of relative changes in thickness, hairiness and so on.

45/0 and 0/45 standard monitoring and lighting geometries
1.3.1.1: 45° – 0° Geometry
In this geometry, the sample is illuminated by a light beam at an incident angle of 45° ± 5°. The light beams reflected from the sample surface under a reflection angle of at most 10° are collected and measured. This geometrical condition is briefly denoted as 45/0.
1.3.1.2: 0° – 45° Geometry
In this geometry, the sample is illuminated by a beam of light under an incident angle of 10°. The rays reflected from the sample surface at a reflection angle of 45° ± 5° are collected and measured. The dispersion of the reflected (observed) light beam should not be more than 5° relative to its axis. This geometrical condition is briefly denoted as 0/45.
