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

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
