Which of the following is NOT a performance characteristic of textiles?

Sheerness is not typically classified as a performance characteristic of textiles in the same way that the other options are. Performance characteristics focus on how a fabric responds to use and environmental factors, such as its durability, breathability, and moisture-wicking properties.

Durability refers to the textile's ability to withstand wear, pressure, or damage, making it an essential characteristic for assessing how long a fabric will last under use. Breathability is crucial for textiles used in clothing and upholstery, indicating how well a fabric allows air to pass through it, contributing to comfort. Moisture-wicking properties describe a fabric's ability to draw moisture away from the skin, which is particularly important in activewear and sports clothing.

In contrast, sheerness primarily describes the visual and aesthetic quality of a fabric rather than its performance in practical applications. While it is an important characteristic, especially in fashion contexts, it does not impact how well a fabric performs under certain conditions. This distinction helps clarify why sheerness does not belong in the category of performance characteristics.
