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
| Parameter | Specifications |
|---|---|
| Temperature Control | 37±0.5°C (human sweat simulation) |
| Humidity | 100% RH (water circulation system) |
| Sweat Solution | Acidic (pH 5.5) and Alkaline (pH 8.0) modes |
| Test Duration | 4–24 hours (programmable) |
| Chamber Dimensions | 300×300×400mm (L×W×H) |
| Power Supply | 220V/50Hz, 0.5kW |
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
- Apparel Manufacturing:Testing sportswear/underwear durability
- Quality Control:Batch inspection of dyed fabrics
- R&D:Developing moisture-wicking treatments
- Forensic Analysis:Evaluating color migration causes
Standard Operation Workflow:
- Sample Preparation: Cut to size, clamp in test chamber
- Parameter Setup: Select sweat type (acidic/alkaline) and duration
- Testing: Initiate programmed sweat cycle
- Analysis: Compare pre/post-test color values via spectrophotometer
- Cleaning: Automated reservoir decontamination
Safety Precautions:
- Avoid contact with acidic/alkaline solutions
- Use grounding straps for electrical components
- Maintain ventilation during testing
