Non-Formaldehyde Dye Fixing Agent Production for Reactive Dye. Business Opportunities in Textile Auxiliaries for Startup
A dye Fixing Agent includes good capability with cross linking agents without promoting dye bleeding. It is generally used after completing the dyeing or in printing paste.
At present, color fixing agent can be divided into cationic fixing agent, resin type fixing agent (containing formaldehyde resin type fixing agent containing polyamine resin type fixing agent) and cross linking reaction type fixing agent.
The dye-fixing agent is applied to the dyed or printed substrate by an exhaust process or by alternative methods, such as padding, spraying, dipping, etc., Application of the dye-fixing agent to the substrate to be finished, may take place either, after the dyed substrate has been removed from the dye bath and has been rinsed, or after the dyed and rinsed substrate has undergone an intermediate drying step.
Dye Fixing Agent find wide application as fixing agents for direct as well as reactive dyestuffs on cellulose fiber. Further, these are also used for bringing necessary improvements in rubbing fastness of direct colors to light and washing.
