In fabric covering, what does durability mainly refer to?

Durability in the context of fabric covering primarily refers to resistance to wear and tear. This characteristic determines how well the fabric can withstand physical stresses, exposure to environmental elements, and the rigors of constant use. When a fabric exhibits high durability, it means that it will maintain its integrity and performance over time, even in demanding conditions often encountered in aviation.

While aspects such as color fastness, thickness, and visual appeal are important in the overall assessment of fabric, they are secondary to the core concept of durability. Color fastness refers to how well a fabric retains its color without fading, thickness relates to the physical dimensions of the material, and visual appeal pertains to the aesthetic qualities of the fabric. None of these factors adequately encompass the concept of durability, which is fundamentally about how well the fabric performs over time against wear and environmental challenges.
