Proportional Dosing
Precision liquid handling systems simultaneously dispense two separate chemical components into a processing unit at a fixed ratio. In textile finishing, dual stream metering allows for the accurate mixing of resins and catalysts that would react prematurely if stored together in a single tank. The system maintains a constant proportion regardless of the total flow rate.
Component Regulation
Dynamic control valves and synchronized pumps regulate the flow of each individual fluid path based on real time data from magnetic flow meters. Effective dual stream metering prevents the common problem of uneven finish application caused by manual batch mixing of sensitive chemicals. Automation ensures the ratio remains identical at the start and end of a production run.
Chemical Stability
Highly reactive mixtures used in water repellent or flame retardant treatments require separation until the point of application. Through dual stream metering, the mill can use high performance finishes that have a short pot life after the catalyst is added. This setup reduces chemical waste by only mixing the amount needed for the fabric currently passing through the applicator.
Meter Verification
Periodic calibration of the flow sensors confirms that the dosage remains within the technical specifications provided by the chemical supplier. Failure in dual stream metering often results in inadequate curing of the finish or sticky residue on the fabric surface.
