Standard Ph Glass Electrode Standardization Procedures for Wet Processing Ranges
Standardizing glass electrodes across wet processing ranges requires bracketed two-point calibration using lithium glass membranes and temperature-corrected buffers.
Stenter Frame Chemical Dosing
Chemical Application
Controlled delivery of finishing agents to the padding trough of a heat-setting oven ensures uniform distribution of functional chemistry across the running fabric. This stenter frame chemical dosing regulates the flow of softeners and resin finishes based on the speed and weight of the material being processed. It maintains a constant bath volume to prevent variations in chemical concentration.
Automated Control
Flow meters and dosing pumps continuously adjust the intake of concentrated finishing chemicals and water. When the fabric speed increases, the system automatically scales up the dosing rate to maintain the target wet pick-up. This real-time regulation prevents the depletion of active ingredients in the applicator, ensuring consistent fabric performance from the start to the end of the batch.
Fabric Quality
Under-dosing leads to inadequate performance, such as poor water repellency or low crease recovery. Over-dosing increases chemical costs and can cause yellowing or reduced tear strength. Precise dosing ensures that the fabric meets the specified performance standards without wasting chemicals or damaging the fiber structure.
Equipment Washdown
Regular flushing of the dosing lines prevents chemical buildup and clogging of the spray nozzles. Cleaning the system between batch changes prevents cross-contamination of different finishes.
