Detergent AR-812 is mainly applied in three major industries: textile printing and dyeing, industrial cleaning, and papermaking, covering core processes such as desizing and scouring, soaping to remove unfixed dyes, metal degreasing and deoiling, hard surface cleaning, and papermaking felt maintenance.
Textile Printing and Dyeing Processing
Detergent AR-812 is most widely used in the textile printing and dyeing field, spanning multiple processes from pretreatment to post-finishing:
- Pretreatment Cleaning: Used after desizing, scouring, and bleaching to efficiently remove residual sizes, impurities, and decomposition products, providing a clean substrate for subsequent dyeing and printing. Suitable for cellulose fibers and their blends.
- Soaping after Dyeing and Printing: Applied in the soaping process after dyeing and printing with reactive dyes, disperse dyes, and vat dyes to remove unfixed floating dyes and residual sizes, significantly improving color fastness and color brightness.
- Synthetic Fiber Scouring and Deoiling: Quickly emulsifies and removes spinning oils and weaving oils from synthetic fibers and their blends, improving fabric hand feel and hydrophilicity.
Industrial Cleaning
- Degreasing and Deoiling of Metal Parts: Surface cleaning of machined parts, stamped parts, and precision components to thoroughly remove cutting fluids, rust preventatives, lubricating greases, etc., meeting requirements for subsequent electroplating and coating processes.
- Hard Surface Oil Cleaning: Suitable for cleaning heavy oil stains on hard surfaces such as mechanical equipment casings, floors, and workbenches. Its strong penetrating and emulsifying abilities rapidly break down stubborn oil dirt.
Papermaking Industry
- Paper Felt Washing and Maintenance: Used for online or offline washing of papermaking felts to dissolve and remove accumulated resins, stickies, fine fibers, and fillers, restoring felt air permeability and elasticity, and extending service life.
