Light optical sensor Loepfe YarnMaster® ZENIT+

chromatic white lightCWSvision processing

Overview
YarnMaster® ZENIT+ is an optical yarn quality control system designed for winding applications. It delivers consistent detection and classification of foreign matter, shade variations and hairiness measurements across different yarn types and ambient conditions, including varying humidity.

Key benefits

• Detection and classification of contaminants, smallest shade variations and specific contaminants such as polypropylene.
• Performance independent of humidity and climatic changes, ensuring consistent optical detection across yarn types.
• Optical hairiness and surface variation monitoring for objective hairiness control and process feedback.

Applications / Recommended for

• Cotton — high-level contamination detection for improved finished yarn quality.
• Core yarn — detection of off-center or missing cores and functions adapted to core yarn requirements.
• Conductive materials — optical measurements adapted to conductive and speciality yarns.
• Colored — detection of subtle shade variations in mélange and dyed yarns.
• Synthetics — identification of process-related faults, hairiness and imperfections irrespective of humidity.
• Blends — configurable detection to address challenges of blended fibres.

Product highlights and operational advantages
ZENIT+ provides steady detection and detailed quality and production reports to support optimisation of preparation and spinning processes. Its optical system consistently identifies raw material and process-related faults in both white and dyed yarns, enabling targeted adjustments to maintain production specifications and reduce defects.

ZENIT+ supports production requirements such as wet-splicing for compact or core yarns while maintaining monitoring capability across different yarn constructions and market demands.
