Causes, Mechanisms and Solutions of Loom Stops: A Productıon and Quality Perspective

Abstract

The weaving stop mark is a quality defect that appears on the fabric surface following planned or unplanned loom stoppages, typically manifested as tonal variation or mechanical deformation. This phenomenon results from the interaction of multiple factors such as production parameters, yarn characteristics, environmental conditions, and operator intervention time. Sudden changes in warp tension equilibrium during stoppage disturb the structural integrity of the fabric, leading to permanent marks that affect both its aesthetic and mechanical properties. Previous studies have revealed that stop mark behavior is not solely dependent on mechanical factors but is also influenced by sizing quality, finishing conditions, warp conditioning, and  restart algorithms. In this study, the mechanisms of weaving stop mark formation are examined from multiple perspectives, evaluating the interrelations among warp tension, loom control systems, material properties, and environmental conditions. Furthermore, mechanical, process-oriented, and data-driven approaches to prevent stop mark formation are compared. The findings provide valuable insights for integrating production efficiency and quality assurance in modern weaving operations.
