Sweat Color Fastness Tester

The Sweat Color Fastness Tester is 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.

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

Technical Parameters

Test Procedures

1. Precautions:

During the testing process, operations should be strictly carried out in accordance with testing standards and operating procedures to avoid human factors affecting the test results.

The instrument should be preheated and calibrated before testing to ensure the accuracy of the test results.

Safety precautions should be observed during the testing process to avoid accidents.

2. Maintenance:

Regular cleaning and maintenance of the instrument should be performed to ensure the normal operation of the equipment and the accuracy of the test results.

Inspect and replace severely worn parts and accessories to extend the service life of the equipment.

Record the parameters and results of each test for subsequent data analysis and comparison.
