Orcomol FAW™ is a water-soluble polymeric dye-complexing agent with stability to hard water and acid and alkali concentrations. Additions of Orcomol FAW™ in stripping procedures gives improved results. The bond of attraction between dyes and Orcomol FAW™ is so strong that the dye has greater affinity for it than for cotton and other fibers. In stripping operations, once the cellulose/dye bond is broken, the dislodged dye is tightly bound to the Orcomol FAW™ — after a prolonged stripping treatment, the Orcomol FAW™/dye bond remains intact.

Dyeing – To lighten deep shades of direct-dyed cellulosic yarns or fabrics.
Textile Printing – To prevent tinting of white backgrounds during soaping.
Scouring – As a soil-suspending agent in detergent washing of cellulosic and protein fibers.
Brightener/Resin Finish Baths – To slow down the exhaust rate of brightener/resin baths containing metal-salt catalysts.
Fulling – Of wool plaids, checks, and tweeds to protect bright colors and prevent staining of whites or in preparations of rag stock for high grade papers.
Stripping – effective as a dye stripping agent for cotton and rayon materials dyed with vat, sulfur, or direct dyes in long liquors, package machines, or jigs.
Fulling – The quantity of Orcomol FAW™ in the fulling bath determines the degree of stripping. However, the concentration of Orcomol FAW™ should not go beyond 1/2 oz/gal. If higher amounts are required in the fulling bath, the liquor ratio should be increased along with Orcomol FAW™. This way the amount of Orcomol FAW™ available for stripping is increased without impairing the bath stability.
