Comparison of different washing fastness testing standards

There are several industry standards for testing washing fastness in textiles, including AATCC Test Method 61, ISO 105-C06, and ASTM D2054. While these standards use different testing procedures and conditions, they all aim to measure the degree of color change or staining of the fabric after exposure to washing or laundering.

Here is a comparison of the different washing fastness testing standards:

1. AATCC Test Method 61: This standard uses a standard washing machine and detergent to simulate home laundering conditions. The test involves washing the fabric specimen multiple times and measuring the degree of color change or staining. AATCC Test Method 61 is commonly used in the United States and is recognized by the American National Standards Institute (ANSI).

2. ISO 105-C06: This standard also uses a standard washing machine and detergent to simulate home laundering conditions. The test involves washing the fabric specimen multiple times and measuring the degree of color change or staining. ISO 105-C06 is commonly used in Europe and is recognized by the European Committee for Standardization (CEN).

3. ASTM D2054: This standard uses a standard perspiration solution to simulate the effect of perspiration on the fabric. The test involves exposing the fabric specimen to the perspiration solution and measuring the degree of color change or staining. ASTM D2054 is recognized by the American Society for Testing and Materials (ASTM) and is commonly used in the United States.

While these standards use different testing procedures, they all aim to measure the degree of color change or staining of the fabric after exposure to washing or laundering. The choice of which standard to use may depend on factors such as regional regulations, customer requirements, and the type of textile product being tested.

In conclusion, textile manufacturers must comply with industry standards for testing washing fastness to ensure that their products meet quality and safety requirements and provide customers with products that maintain their color and appearance over time.
