AATCC 116 Resistance to crocking colour transfer method

The AATCC 116 test evaluates the resistance of textile products to color transfer during rubbing, which is known as "crocking." This type of color transfer can occur in various environments such as home use, commercial laundering, or transportation. The primary focus of this test is to assess the durability and quality of textiles by ensuring that colors remain fixed on the fabric during routine handling.

Color crocking refers to the unintended transfer of dyes from one textile surface to another. This phenomenon can be detrimental for both consumer satisfaction and brand reputation, especially in industries like fashion, home furnishings, and automotive fabrics. To mitigate these issues, AATCC 116 provides a standardized method that allows fabric manufacturers and suppliers to ensure their products meet quality standards before they reach the market.

The test involves rubbing a specimen with a standard rubbing pad containing abrasive particles over a fixed area for a specified duration under controlled conditions. After the rubbing process, the color transfer is quantified by comparing the initial colorfastness of the fabric against its condition post-rubbing using advanced spectrophotometric techniques.

Understanding the intricacies of AATCC 116 requires knowledge of several key components:

Test Specimen: Typically, a small piece of fabric measuring approximately 5 cm x 5 cm is cut from the test sample. This specimen should be representative of the colorfastness properties of the entire fabric.
Rubbing Pad Composition: The rubbing pad consists of silica particles with specific particle sizes and distribution to simulate real-world frictional conditions accurately.
Instrumentation: High-precision spectrophotometers are used to measure color changes before and after the rubbing process. These instruments provide precise numerical values that quantify the extent of color transfer.
Rubbing Force: The rubbing force is crucial in simulating real-world conditions. It ensures that the frictional forces applied during the test accurately reflect those experienced by the fabric during use.
Test Duration and Frequency: The duration and frequency of rubbing are standardized to ensure consistency across tests, allowing for accurate comparison between different specimens or batches of fabric.

The results of this testing method provide valuable data that help manufacturers make informed decisions about dye selection, fabric construction, and finishing processes. By adhering to AATCC 116 standards, companies can enhance consumer trust and maintain their brand's reputation for quality and durability.

Failure to meet the colorfastness requirements set by this standard may lead to product recalls or legal action, which could significantly impact a company’s financial health and customer relations. Therefore, investing in robust testing methodologies like AATCC 116 is essential for any organization involved in textile production.
