Twist Loss (Carpet)

Floor Detective® Claims and Conditions Guide

Summary

Twist loss is an appearance-retention condition in which carpet yarns lose their ability to maintain intended twist configuration under normal use. Yarn twist is a primary structural characteristic that binds fibers together within the pile, and when twist stability is limited, yarns may relax, open, bloom, or lose surface definition over time. Observable effects may include a fuzzy, untidy, or less defined surface appearance, particularly in traffic areas subjected to repeated compression and shear forces. Twist loss affects appearance retention and yarn cohesion rather than backing integrity or structural breakdown of the carpet system. See also Pilling, Matting, and Carpet Problems for broader context.
