Warp End Breakage

Yarn Failure

Thread rupture occurs when a longitudinal yarn on a loom snaps due to excessive tension or inherent weak spots. The rate of warp end breakage is a primary metric for measuring the efficiency of the weaving shed and the quality of the sizing process. Each break requires the loom to stop automatically, which reduces the total output of the factory.

This value is usually expressed as the number of breaks per hundred thousand picks.

Failure Analysis

Frequent breaks often indicate an issue with the yarn preparation or the settings of the loom. If the flax yarn has not been properly sized, it will lack the strength to withstand the rhythmic shedding and beating-up actions. Warp end breakage can also be caused by knots or slubs that were not caught during the spinning or winding stages.

Analyzing the location and the type of break helps the weaver identify whether the problem lies with the raw material or the machine. High breakage rates not only lower productivity but also increase the number of knots in the finished fabric. Maintaining the correct humidity in the loom shed is the most common way to reduce these failures.

Productivity Impact

A high-performing mill targets a breakage rate that allows a single weaver to manage multiple looms simultaneously. This ratio determines the labour cost of the woven linen.
