JIS Rubbing Colour Fastness Tester | Testing Equipment
TheJapanese 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.
Compliance Standards
JIS L 0849 (Colorfastness to rubbing)
ISO 105-X12 (International colorfastness test)
AATCC 8 (Durability of colorfastness)
GB/T 3920 (Chinese textile abrasion standard)
Key Features
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
