Floor Detective® Claims and Conditions Guide

Summary

Mixed yarn, commonly referred to as chicken tracks, wild yarn, or mixed fiber streaking, is a manufacturing-origin appearance condition caused by yarns with different fiber chemistry or processing characteristics being incorporated into the same carpet construction. Differences in polymer type, crimp, twist, heat-setting, or stretch history cause affected yarns to absorb dye or reflect light differently than surrounding yarns. This creates visible streaks, zigzag patterns, or irregular lines within the carpet surface. The condition commonly follows machine-direction tufting patterns and may become more visible under directional lighting or after grooming. Mixed yarn affects appearance only and does not independently reduce tuft bind, backing integrity, durability, or service life. The condition may resemble Foreign Yarn or Machine Oil Contamination, but mixed yarn results from inherent yarn variation rather than contamination or unintended foreign material insertion. See also Foreign Yarn, Machine Oil Contamination, and Carpet Problems for broader context.
