Optimizing Shed Height Settings for Air Jet Linen Fabric Construction
Optimizing air jet linen shedding requires asymmetric harness levelling at 26 millimetres to balance relay nozzle clearance with tension limits.
Weaving Capacity
Production Limit
The maximum volume of fabric that a mill can produce under standard operating conditions is determined by its mechanical and yarn limitations. This output potential is the weaving capacity, which is measured in terms of picks per minute or square meters of fabric per loom-hour. In linen factories, this potential is heavily influenced by the raw material quality because the brittle nature of flax fibres limits loom speeds.
Speed Determination
Running looms at maximum mechanical speed is rarely possible when weaving linen fabrics. The actual weaving capacity must be adjusted downward to avoid high yarn breakage rates that would cause too many machine stops. If the loom is run too fast, the abrasive forces of the reed and harness frames will degrade the warp yarn, resulting in poor fabric quality.
Therefore, a balance must be struck between output speed and yarn survival rate. Using wet-spun yarns instead of dry-spun yarns allows the mill to increase this output threshold because of the superior strength of wet-spun yarn.
Efficiency Maximization
High-quality sizing and yarn preparation are necessary to achieve the maximum possible machine output. Optimizing these early stages increases the weaving capacity by reducing loom downtime caused by warp and weft failures. Consistent yarn quality enables the mill to operate at higher loom speeds without increasing stop rates.
