Friction Coefficient
Excessive surface adhesion during the mechanical drafting of flax roving reduces production speed. Inter-yarn cling describes the electrostatic and structural bond strength between parallel strands when they contact each other under tension. This phenomenon arises when residual moisture or insufficient sizing agent on the fibres creates a sticky interface.
Operators document the value within the mill production log to determine if additional anti-static treatment or lubrication is necessary for the spinning frames.
Processing Resistance
Variations in the fibre surface texture alter how these bundles move through the rollers. Because inter-yarn cling locks individual fibres into localized clumps, the machine exerts higher force to pull the mass apart. Higher values force the maintenance team to slow the line speed to prevent snapped strands.
A stable measurement confirms the consistency of the chemical application stage prior to spinning.
Quality Benchmark
Textile standards define the acceptable range of surface attraction based on the final fabric density requirement. These criteria establish a clear separation between raw fibre characteristics and the artificial drag created during processing. Buyers request this data to verify that the incoming material will perform correctly on their own high-speed looms.
Stable adhesion metrics prove the chemical processing was uniform across the entire batch.
