Everything You Need to Know About Rotary Color Fastness Testing

Rotary color fastness testing is a commonly used textile testing method for evaluating the color fastness of dyed fabrics. Here's everything you need to know about rotary color fastness testing:

1. Test principle: Rotary color fastness testing is to put the dyed fabric sample and standard cotton cloth into the dyeing solution, then rotate the sample to simulate the washing process, and finally evaluate the color fastness of the fabric.

2. Testing standards: rotary color fastness testing usually follows international standards such as ISO, AATCC, and JIS. The test conditions and evaluation methods required by different standards may be different, so it is necessary to select the appropriate standard before testing.

3. Test equipment: Rotary color fastness testing requires a rotary color fastness tester. This device simulates the washing process and evaluates the color fastness of fabrics by spinning samples.

4. Test process: The test process includes the steps of putting the fabric sample and standard cotton cloth into the dyeing solution, rotating the sample, washing, rinsing, centrifuging, and drying. After the test is completed, it is necessary to use a gray scale card or a colorimeter to evaluate the color fastness of the fabric.

5. Test results: The results of the rotary color fastness test are usually expressed in numbers, and the higher the number, the better the color fastness. Generally speaking, fabrics with a color fastness of 4 or above can be considered to have good color fastness.

6. Test application: rotary color fastness testing is suitable for various textiles, including clothing, home textiles, automotive interiors, etc. This test method can help manufacturers evaluate the durability and quality of fabrics, thereby improving the competitiveness of products.
