Auxiliaries are common in printing and dyeing


Auxiliaries commonly used in printing and dyeing are:  

Leveling agent: The dye is slowly absorbed by the fiber or can make the dark part of the dye to the light part of the diffusion and does not reduce the dyeing firm degree  
Fixing agent: Make the dye into insoluble dye salt, or make the dye molecules large and difficult to dissolve in water, so as to improve the firm degree of dyeing.  
Dispersing agent: Help in particle crushing, maintain the stability of dye dispersion.  
Fabric softeners A protective film is uniformly applied on the surface of fabric fiber, and the friction coefficient between fibers is reduced due to the absorption of softener on the fiber surface.  
Colouring agent: Dyeing is the main body of dyeing process, different fiber fabrics use different color agents, and according to the different process, dye processing AIDS help solvents, dispersants, chromogens and phthalocyanine AIDS.  
Adhesive: After printing does not change color, does not damage the fiber, has a certain elasticity, feel good.  
Thickening agent: To thicken the color, promote adhesion and emulsification and other functions, the use of printed fabric to obtain uniform, soft profile clear pattern.
