CRN ROH PMZ is a specialized high-performance scouring agent designed for the dyeing and post-processing of polyester (PES) and its blends. It excels at stabilizing and removing oligomers that migrate to the fiber surface during high-temperature dyeing, which typically cause "dusting," dullness, and white spotting. Its high-foaming nature ensures that the chemical reaches every corner of the machinery and fabric folds for a comprehensive clean.
Why It Should Be Preferred?
Advanced Oligomer Dispersion: Breaks down and suspends oligomer crystals in the dye bath, preventing redeposition on the fabric.
Superior Cleansing Power: Rapidly removes oils, spinning lubricants, and processing residues from the substrate.
High-Foaming Carrier Effect: Utilizes the mechanical power of foam to transport impurities away from the fabric even in complex machinery setups.
Improved Fastness Ratings: By removing loose dyestuffs during post-dyeing washes, it significantly enhances rubbing and laundering fastness.
Machinery Protection: Prevents the buildup of oligomer scale on heat exchangers and machine walls, reducing maintenance downtime.
Areas of Usage
Polyester Dyeing Processes: Added directly to the dye bath or used in reduction clearing to manage oligomer levels.
Dark Shade Finishing: Essential for jet black and navy blue fabrics where white oligomer dust is most visible.
Continuous & Batch Washing: Ideal for scouring lines where high-foam stability contributes to better dirt removal.
Industrial Machine Cleaning: Periodic descaling of dyeing vessels and internal components from polyester-related residues.
