    摘要： The present disclosure relates to a method for manufacturing artificial leather having excellent fastness and dyeing properties by using a dope-dyed polyester sea-island type composite yarn, and artificial leather produced by the same method.
    According to the present disclosure, a non-woven fabric, which is made of a dope-dyed polyester sea-island type composite yarn to which an organic or inorganic pigment, or both an organic pigment and an inorganic pigment, are added, is produced by: impregnating the same with a polyurethane resin to which an organic or inorganic pigment, or both an organic pigment and an inorganic pigment, are added; performing weight reduction processing; and then dying the same with a disperse dye, whereby various colors can be expressed, the artificial leather is uniformly dyed with the pigment, the amount of dye used can be reduced by excellent dyeability and deep color expression, and excellent fastness and high-grade quality are expressed, thereby making it possible to develop products for advanced applications such as interior materials for a vehicle.

    摘要： The present invention is directed to a disperse dye of formula (1) Wherein, X, Y and Z are, independently, hydrogen, halogen, cyano, nitro or SO2F; Wherein at least one of X, Y and Z is SO2F. R1 is hydrogen, methyl, hydroxyl or NHR4; R2 is hydrogen, chloro or methoxy; R3 is hydrogen, (C1-C4)-alkyl or -CH2(CH2)nCOOCH2CN; R5 is hydrogen, (C1-C4)-alkyl or -CH2(CH2)mCOOCH2CN; R4 is -COCH3, -CO C2H5, -SO2CH3 or SO2C2H5; n and m are independently 0,1 or 2, with the proviso: -When, Y and Z both are Cl, R1 is other than methyl. When, R2 is Hydrogen and R3, R4 both are alkyl, R1 is selected from NHSO2CH3 or NHSO2C2H5. Disperse dyes of Formula (I) have excellent washing fastness and light fastness on polyester fiber and polyester blends.
