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) |

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
