Sweat Color Fastness Tester-QINSUN

• 

I. Product Overview

TheSweat Color Fastness Testeris a specialized instrument designed to evaluate the colorfastness of textiles against perspiration-induced fading. It simulates human sweat conditions (pH, temperature, and composition) to quantify color bleeding and staining resistance, critical for quality assurance in apparel manufacturing.

• Type: Environmental simulation testing chamber
• Test Standards: ISO 105-E04, AATCC 106, GB/T 3922
• Key Metrics:
  • Color Change ΔE (CIELAB)
  • Staining Intensity (1–5 scale)
  • Sweat Penetration Depth (mm)
• Sample Size: 100×100mm (adjustable clamping)

II. Technical Specifications

III. Key Features

• Dual Sweat Simulation:
  • Acidic Mode:Mimics human eccrine sweat
  • Alkaline Mode:Simulates sebaceous sweat
• Advanced Detection:
  • 3D color mapping (CIE Lab/LCh)
  • AI-based stain classification (5 severity levels)
  • Real-time pH monitoring
• Automation:
  • Auto-fill/empty sweat solution reservoir
  • Programmable drip rate (1–10 mL/hr)
  • Self-cleaning drainage system

IV. Compliance Standards

• ISO 105-E04 (Textile colorfastness to sweat)
• AATCC 106 (Colorfastness to perspiration)
• GB/T 3922 (Chinese sweat fastness standard)
• EN ISO 105-C06 (Extended colorfastness tests)

V. Applications

1. Apparel Manufacturing:Testing sportswear/underwear durability
2. Quality Control:Batch inspection of dyed fabrics
3. R&D:Developing moisture-wicking treatments
4. Forensic Analysis:Evaluating color migration causes

Standard Operation Workflow:

1. Sample Preparation: Cut to size, clamp in test chamber
2. Parameter Setup: Select sweat type (acidic/alkaline) and duration
3. Testing: Initiate programmed sweat cycle
4. Analysis: Compare pre/post-test color values via spectrophotometer
5. Cleaning: Automated reservoir decontamination

Safety Precautions:

• Avoid contact with acidic/alkaline solutions
• Use grounding straps for electrical components
• Maintain ventilation during testing
