Balancing Bast Fiber Loom Shed Relative Humidity and Warp Regain
Balancing bast fiber loom shed humidity requires maintaining 76-80% RH to achieve 12% warp regain, preserving yarn elasticity and preventing size film dusting.
Ultrasonic Shed Humidification
Droplet Emission
High-frequency electronic transducers generate fine water mists that control the relative humidity of weaving rooms without wet precipitation. Using ultrasonic shed humidification allows spinning and weaving mills to maintain the optimal moisture levels required for processing spun flax. This technology operates with low energy consumption while providing immediate adjustment of ambient moisture.
Yarn Condition
Spun linen yarns must maintain a high moisture content to withstand the rapid mechanical movements of modern looms. Implementing ultrasonic shed humidification ensures that the fibers do not become brittle or lose their elasticity during the high-speed weft insertion. This continuous moisture supply maintains yarn strength and prevents frictional abrasion in the weaving zone.
Atmospheric Uniformity
The tiny droplet size generated by ultrasonic devices ensures that the moisture evaporates completely before it can settle on the mechanical parts of the loom. This dry mist prevents water droplets from dissolving the starch sizing applied to the warp yarn, which would cause the threads to stick together and break. By distributing humidity evenly across the weaving floor, this humidification system ensures that warp tension remains uniform and warp breakages are kept to a minimum across all active machines.
This precise localized control is especially useful in mills with variable ventilation patterns where traditional spray nozzles would create wet regions.
