Eco carrier N-9A is a carrier that can be used for disperse dyeing deep color for polyester and its blend fabrics and yarns at low temperature. It enhances polyester plasticated, swollening in dye liquor, and has excellent abilities of solubilizing and migration to disperse dye, then carry the point of dyeing at low temperature. Compared to routine carriers as sweet brich oil and phenol, it has basically no peculiar smell around the surroundings, no residual odor dyed fabrics. The product has no APEO and phthalates, accord with eco request.

Characteristics and advantage
Debases glass transition temperature of polyester, advances dyeing rate and dye saturation value of disperse dye.
Has excellent effects of dispersing, leveling and migration to disperse dye.
Low dosage, outstanding effect, high dye up-take.
Self-emulsifying in water, can be easily dispersed in cold water, easy operation, easy using.
Used as color repairing agent for polyester dyeing defect, has obvious effect.
