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

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

1. Quality Control:Monitoring fleece fabric uniformity
2. R&D:Developing high-loft insulation materials
3. Forensic Analysis:Evaluating wear-induced fiber damage
4. Textile Education:Training on fiber structure analysis

Standard Operation Workflow:

1. Sample Mounting: Secure fabric on vacuum table
2. Parameter Setup: Select test mode (static/dynamic)
3. Scanning: Full-area fiber mapping (2–10 minutes)
4. Analysis: Generate loop length distribution curves
5. 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
