Fiber Length Analyzer
Product Introduction & Applications
The Fiber Length Analyzer adopts a roller-type measuring principle. During testing, the prepared cotton or chemical fiber sliver is divided into groups and weighed according to preset grouping rules. Through this process, the instrument calculates multiple fiber length indexes, enabling accurate evaluation of fiber length distribution.
This instrument consists of two main components:
Fiber draw-off unit
Roller-type fiber analyzer
It is suitable for analyzing the length of:
Cotton fibers
Chemical fibers
Fiber sliver prepared through trash extraction and draw-off procedures
The system is designed for textile mills, fiber research institutes, quality inspection agencies, and laboratories that need to determine fiber length distribution, group length, and effective length.
Standards Compliance
The instrument complies with:
GB/T 6908.1 — Study on measuring method of roller-type cotton fiber length
This ensures the measuring method and process meet national requirements for fiber length evaluation.

FAQ
1. What types of fibers can the Fiber Length Analyzer test?
It is designed for cotton fibers and chemical fibers, especially sliver samples requiring length group distribution analysis.
2. What is the purpose of grouping and weighing?
Grouping and weighing help determine fiber length distribution, allowing calculation of effective fiber length and other indicators.
3. Does the instrument require special sample preparation?
Yes. The sliver must undergo trash extraction and fiber draw-off before analysis to ensure accuracy.
4. What is the measurement method used?
The analyzer uses a roller-type measurement system, consistent with the requirements of GB/T 6908.1.
5. What industries commonly use this analyzer?
Cotton processing mills
Textile factories
Fiber testing laboratories
Scientific research institutions
