Fibre Application
Aqueous paraffin dispersions reduce the friction coefficient during the mechanical processing of flax fibres to prevent mechanical heating and static charge accumulation. Wax emulsion lubrication is applied during the final drafting or roving stages to ensure even tension and fibre alignment before spinning. This substance coats the outer surface of the bast fibre bundles to improve surface smoothness.
Decreased fibre breakage results from this treatment when the material passes through high speed spinning frames.
Processing Requirement
Machine settings dictate the appropriate solid content percentage of the mixture to achieve uniform distribution without leaving heavy deposits on the spinning rollers. Excessive application causes the buildup of sticky residue which hampers the cleaning of machine components and reduces the consistency of yarn count. Technicians monitor the viscosity of the fluid to ensure stable flow through the metering pumps.
Precise control of the wet pick up rate prevents irregular absorption across the roving batch. Optimal dosing creates a protective layer that withstands the mechanical stress of winding operations.
Quality Verification
Acceptance of the treated lot rests upon the absence of discolouration or fibre matting caused by uneven drying. Inspection documents record the mass balance of the applied chemical against the dry weight of the flax output to confirm adherence to customer specifications. Suppliers maintain logs detailing the surfactant to wax ratio to guarantee the stability of the mixture throughout the batch run.
Final yarn characteristics demonstrate that controlled deposition improves the efficiency of subsequent weaving and knitting processes.
