Thermal Parameter
Heat levels in the aqueous bath during the removal of starches or waxes define the efficiency of the cleaning phase. Maintaining a specific desizing temperature ensures that the amylase enzymes break down the size film without damaging the underlying flax cellulose. If the heat fluctuates outside the prescribed range of 60 to 90 degrees Celsius, the chemical reaction stalls or the fiber degrades.
Enzyme Velocity
Molecular activity within the treatment liquor depends on consistent heat to sustain the hydrolysis of starch-based sizing agents. Modern linen mills monitor the desizing temperature using automated sensors that adjust steam valves to prevent cold spots in the continuous washer while maintaining a steady chemical potential. Stable heat prevents the re-precipitation of dissolved solids onto the fabric surface and ensures that the subsequent bleaching and dyeing steps proceed with a clean, receptive substrate for the colorants.
Fabric Integrity
High heat levels during the desizing stage can lead to excessive weight loss or weakened yarn structures if the exposure time exceeds mill specifications. Practitioners record the desizing temperature on the batch processing sheet to verify compliance with buyer acceptance standards for tensile strength. Consistent thermal management remains a requirement for high-speed finishing lines.
