Reed Mark and Warp Streak Prevention
topic
Reed marks and warp streaks are warp-direction fabric defects caused by localised thread spacing anomalies from damaged reed dents, incorrect denting that groups threads unevenly, or systematic warp tension differences between thread groups that compact differently, creating visible light-and-dark stripe patterns in the finished fabric that are particularly visible after dyeing in solid colours, with prevention through regular reed inspection, accurate denting, and tension uniformity maintenance across the warp width.
Role
Addresses the warp-direction defect category that is typically more difficult to eliminate than weft-direction bars because the causes are often accumulative from progressive reed wear or systematic denting errors rather than the acute process parameter changes that cause weft bars, requiring the regular preventive maintenance of reed replacement and denting quality control that prevents defect accumulation rather than the reactive adjustment that weft bar management sometimes allows.
