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 relates to an artificial leather composed of a dope-dyed polyester fiber, which comprises carbon black in island component of a sea-island composite fiber and polyurethane polymer elastomer during producing an artificial leather.
According to the present invention, it is possible to improve the fastness to light and the fastness to rubbing at medium and deeper color, and at the same time, to have a luxuriously high quality and to reduce the amount of dye used in the production of artificial leather.
