Blocking agent NP20-107 is the polycondensation product of anionic aryl sulfonic acid, suitable to use as restraining agent of wool/nylon/polyamide fibers blended staining, control acid dye levelness of blended works polyamide fiber preferred dyeing wool/nylon, polyamide fiber blended to monochrome dyeing, its mechanism is more like colorless levelness, acid dyes in cotton nylon dyed seat was dyed.
Features and Benefits:
1 Dye N/C fabric, can be generated blocking effect for direct dye, prevent its contamination in nylon fibers
2 Give better smooth and antistatic effect for fabric
3 The product is acidproof, alkaliproof, the effect to restraining acid mordant dyes and resistance fulling acid dyes is not obvious, it is not recommended for this type of dye.
