Fleece Loop Length Tester

I. Product Overview

The Fleece Loop Length Tester is 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)

• 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

• 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)

1. Quality Control: Monitoring fleece fabric uniformity
