Hydrodynamic Refining
Mechanical fibre separation processes utilize high-velocity fluid forces to detach pectin and lignin from plant bast bundles without harsh chemical degradation. Textile research facilities apply liquid shear extraction to refine decortication waste into spinnable flax microfibres for high-count yarn blending. Fluid jets break intercellular bonds along natural fibre middle lamellae.
Ultrasonic agitation supports fluid shear action inside closed reactor tanks. Cleaned bast strands retain cellulose structural integrity throughout processing.
Degumming Mechanics
High-pressure liquid streams force pectinaceous gums out of raw bast bundles during continuous immersion. Operational parameters during liquid shear extraction control fluid temperature, flow velocity, and nozzle distance to achieve uniform fibre separation. Cavitation bubbles collapse against plant cell walls to accelerate gum dissolution.
Organic effluents drain continuous washing chambers after separation.
Fibre Yield
Fibre fineness measurement confirms the structural transformation of coarse bast bundles into flexible single fibres. Processing mills implementing liquid shear extraction achieve refined flax fibres with linear densities suitable for wet-spinning fine linen yarns. Yield measurements record reduced non-cellulosic impurity percentages on laboratory test sheets.
Treated fibres exhibit increased water absorption capacity compared to mechanically scutched flax. Spinning mills mix extracted microfibres with combed cotton or silk on rotor spinning lines. Production reports log energy consumption per kilogram of refined fibre.
Technical evaluation confirms preserved tensile strength in output strands.
