Best yarn clearers for colored yarn manufacturers

Secure hairiness detection & unaffected by humidity: The Loepfe optical infrared sensor offers a notable advantage: it remains unaffected by humidity, climatic changes, or the material being inspected. As the established leader in hairiness detection, the optical infrared sensor is highly reliable.

Detection of colored foreign matter in dyed yarn: Foreign matter of any color and material can be proficiently detected. This includes identifying colored foreign matter in raw white and dyed yarn.

Elimination of smallest shade variations: The OffColor (Option) feature detects and eliminates even the smallest shade variations. To achieve this, the yarn is illuminated from multiple angles to detect any color variations.

For all splicer types: All Loepfe winding yarn clearers include a splice accumulation feature, designed to enhance productivity and efficiency. This feature remains active after each cut for 25 meters. Moreover, the ZENIT+ system is versatile and compatible with all splicer types, the user to choose what suits their specific needs.

Secure polypropylene detection:  The invisible becomes visible with the triboelectric P sensor.

• Detection of raw white and transparent polypropylene
• Detection of white PP faults in blended cotton yarn
• Detection of even the finest synthetic foreign matter

While the yarn passes the P sensor, the fibers exchange electrons with the sensor. This effect is referred to as the „triboelectric effect“. When a synthetic fiber passes the electrode of the sensor, it is detected because of the triboelectric charge difference.
