The Japanese Standard Color Fastness to Rub Tester (Gakushin) is a specialized instrument designed to evaluate the colorfastness of textiles to friction and abrasion, adhering to JIS L 0849 (Japanese Industrial Standard). It quantifies color transfer and staining resistance under controlled rubbing conditions, critical for ensuring compliance with Japanese textile quality requirements.
JIS L 0849 (Colorfastness to rubbing)
ISO 105-X12 (International colorfastness test)
AATCC 8 (Durability of colorfastness)
GB/T 3920 (Chinese textile abrasion standard)
JIS L 0849 Compliance:
Simulates real-world friction (e.g., garment rubbing)
Standardized felt pad and load system
Advanced Features:
Real-time color difference analysis (ΔE)
AI-based staining classification (5 severity levels)
Anti-slip clamping mechanism
Automation:
Programmable cycle counter
Motorized rubbing head
Self-cleaning abrasive pad holder
Textile Manufacturing: Testing dyed fabrics for consumer goods
Quality Control: Batch inspection of apparel and home textiles
R&D: Developing fade-resistant dyes and finishes
Forensic Analysis: Evaluating wear-induced color degradation
Standard Operation Workflow:
Sample Preparation: Cut to size, clamp in test frame
Parameter Setup: Select cycle count and rubbing force
Testing: Initiate automated rubbing cycles
Analysis: Measure color transfer via spectrophotometer
Cleaning: Automated pad decontamination
Safety Precautions:
Avoid contact with moving parts during operation
Use heat-resistant gloves when handling samples
Maintain ventilation in testing area
