In the pre-treatment of woven fabrics, desizing and bleaching are traditionally conducted as two separate sequential steps. CRN COMBI AGM is a high-tech combined scouring agent with integrated desizing properties, engineered to merge these critical stages into a single bath. While effectively breaking down the sizing layer on woven yarns, it simultaneously brings the fabric to the ideal whiteness and hydrophilicity required for subsequent dyeing.
Integrated Desizing and Bleaching Technology
Thanks to its specialized polymeric components and surfactant system, CRN COMBI AGM rapidly detaches starch-based and synthetic sizing agents from the fiber and keeps them suspended (dispersion) within the bath. This "all-in-one" approach provides:
Process Speed: Total production time is reduced by approximately 30-50% by eliminating the need for a separate desizing bath.
Resource Efficiency: Drastic reductions in water, steam, and electricity consumption.
Machine Productivity: Increases machine turnover due to fewer bath changes and simplified processing.
Sequestration and Peroxide Stabilization
As a combined auxiliary, CRN COMBI AGM manages the chemical process beyond mere cleaning. It stabilizes hydrogen peroxide during bleaching, preventing uncontrolled decomposition and subsequent fiber damage (pin-hole risk). By encapsulating water hardness ions and metallic residues, it prevents graying or spotting on the fabric during the intensive desizing process.
Key Advantages of CRN COMBI AGM
Powerful Cleaning Performance: Simultaneously removes sizing residues and natural oils/waxes.
High Whiteness Index: Prepares a uniform and brilliant white base, even during the desizing phase.
Superior Hydrophilicity: Imparts the rapid water absorbency essential for consistent dyeing and printing.
Residue Control: Contains specialized dispersants that prevent the redeposition of degraded sizing materials back onto the fabric.
Ecological Advantage: Facilitates better wastewater management by reducing chemical variety and process steps.
