Which attribute is NOT typically compared in fiber analysis?

In fiber analysis, reliable matching relies on stable, intrinsic properties that are consistent across samples and can be measured objectively. Color, dye composition, and weave are typical attributes studied because they reflect the fiber’s material, manufacturing process, and treatment, and they can be quantified or observed under controlled conditions. Odor, on the other hand, is not typically compared because it is highly subjective and variable. Smell can change with age, cleaning, environmental exposure, and even who is perceiving it, making it an unreliable basis for identifying or linking fibers. While a smell might occasionally provide contextual clues, it does not offer the reproducible, demonstrable evidence needed for forensic comparisons.
