Optimizing Wet Pick up Values in Flax Warp Slashing
Optimizing flax wet pick-up between 80 and 95 percent balances film encapsulation with core penetration, minimizing loom warp breaks and sizing liquor cost.
Shedding Dust Generation
Dust Formation
Abrasive friction between moving warp yarns and heald wires releases fine flax particulates into the weaving shed atmosphere. During high speed loom operation, shedding dust generation quantifies airborne fiber fragments and degraded size solids produced as warp ends separate. Mill environmental monitoring records air sample dust concentration in milligrams per cubic meter using optical dust counters placed around weaving frames.
Low extensibility of flax causes microscopic surface fibrils to shear off under cyclic tension. The metric measures airborne debris specifically created by mechanical friction in the harness area and excludes ambient floor waste.
Fiber Release
Brittle starch size coatings fracture under high warp tension during shed opening, releasing micro particles into working zones. Short fiber fragments escape from dry spun flax yarns more readily than from smooth wet spun yarns. Heavy dust accumulation clogs loom stop motions, causing false electrical signals and unwanted machine downtime.
High ambient relative humidity keeps flax fibrils flexible, reducing particle detachment from warp threads.
Abatement Control
Under loom vacuum exhaust systems capture dust directly at the heald frame zone to maintain ambient air quality. Compliance with workplace safety standards requires air filtration turnover rates that keep airborne dust concentrations below local industrial limits.
