Fleece Loop Length Tester
I. Product Overview
TheFleece Loop Length Testeris a specialized instrument designed to measure the fiber loop length distribution in fleece fabrics, critical for evaluating softness, bulkiness, and durability. It utilizes non-contact laser scanning technology to ensure precise and repeatable measurements aligned with international textile standards.
- Type: Automated fiber analysis system
- Measurement Range: 10–1000 μm (loop length) | 0.1–50mm²/s (fiber density)
- Sample Type: Knitted fleece, woven pile fabrics, artificial fur
- Key Metrics:
- Loop length average (μm)
- Fiber density (fibers/cm²)
- Loop uniformity coefficient (CU)
II. Technical Specifications
| Parameter | Specifications |
|---|---|
| Measurement Principle | Laser micrometer + AI pattern recognition |
| Resolution | ±0.5 μm (ISO 137 standard validation) |
| Sample Size | 100×100mm (adjustable clamping frame) |
| Scanning Speed | 300 mm/s (full-area mapping) |
| Power Supply | 220V/50Hz, 0.8kW |
| Dimensions | 500×400×700mm (W×D×H) |
III. Key Features
- Dual Measurement Modes:
- Static Mode:Fixed sample analysis
- Dynamic Mode:Simulates stretching/compression
- Advanced Analysis:
- 3D loop structure visualization
- Real-time histogram distribution
- Batch data comparison (Excel/PDF export)
- Automation:
- Auto-focus laser calibration
- Anti-drift sensor system
- Self-cleaning optical lens
IV. Compliance Standards
- ISO 137 (Textile fiber length and fineness)
- ASTM D1414 (Fiber length in flocking fabrics)
- AATCC 20A (Fiber analysis methodology)
- GB/T 14335 (Chinese fiber length standard)
V. Applications
- Quality Control:Monitoring fleece fabric uniformity
- R&D:Developing high-loft insulation materials
- Forensic Analysis:Evaluating wear-induced fiber damage
- Textile Education:Training on fiber structure analysis
Standard Operation Workflow:
- Sample Mounting: Secure fabric on vacuum table
- Parameter Setup: Select test mode (static/dynamic)
- Scanning: Full-area fiber mapping (2–10 minutes)
- Analysis: Generate loop length distribution curves
- Reporting: Export compliance-ready data
Safety Precautions:
- Avoid direct eye exposure to laser beams
- Use grounded power supply only
- Clean optical components with isopropyl alcohol
