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
