Summary

Fiber degradation is a material performance condition in which the polymer structure of carpet fibers undergoes chemical or environmental breakdown, resulting in reduced strength, reduced elasticity, and gradual loss of structural integrity. The condition may develop through ultraviolet (UV) exposure, oxidative aging, chemical interaction, or combined environmental stress over time. As degradation progresses, fibers may become brittle, fragmented, chalky, or weakened under normal use conditions. Distribution commonly follows exposure patterns such as sunlight, chemical contact, or environmental influence rather than isolated mechanical wear. Fiber degradation affects the internal fiber structure rather than surface compression alone and may resemble matting or fading depending on severity and exposure conditions.
