What does "chemical resistance" refer to in textile certification?

Chemical resistance in the context of textile certification specifically pertains to a fabric's ability to withstand exposure to various chemicals without undergoing significant degradation. This property is crucial for fabrics used in environments where they might come into contact with hazardous substances, such as industrial settings, laboratories, or medical applications.

A fabric that is chemically resistant will not easily corrode, discolor, or lose its mechanical properties when exposed to chemicals like solvents, acids, or even certain cleaning agents. Therefore, understanding and measuring this characteristic is vital for ensuring safety, durability, and performance in specific applications.

The other options focus on different aspects of fabric properties. Dust repulsion relates to a fabric's surface characteristics and does not address chemical interactions. Similarly, color fading is concerned with the longevity of dye and colorfastness rather than chemical interactions. Lastly, the weight and thickness of a fabric pertain to its physical structure but do not directly relate to how it reacts when exposed to chemicals.
