The dyed artificial leather according to the invention includes a fibrous base containing ultrafine fibers with a filament fineness of 2 decitex or less and a polymeric elastomer, and characterized in that the lightness difference ”L* between the ultrafine fibers and the polymeric elastomer represented by the following equation meet the requirement of -16‰¤”L*‰¤5: ”L * = average lightness L * of ultrafine fibers ˆ’ average lightness L * of polymeric elastomer . The production method for dyed artificial leather according to the present invention is characterized by including a first dying step in which artificial leather constituted mainly of a fibrous base containing ultrafine fibers with a filament fineness of 2 decitex or less and a polymeric elastomer is dyed using a dye and a subsequent second dyeing step performed at a dye concentration that is 0.1% to 30% of the dye concentration (owf) in the first dyeing step.

Abstract: PROBLEM TO BE SOLVED: To provide a stable finishing method for dyeing a fabric of moisture- absorptive, core-sheath type composite of polyester by treating the fabric with an alkaline solution and then with steam, to prevent cracking of the sheath and evolution of lines both in the lateral and longitudinal directions. SOLUTION: This method (A) treats a fabric of moisture-absorptive, core- sheath type composite of polyester fibers, copolymerized with a hydrophilic compound having a maximum thermal swelling rate of below 100 deg.C and containing a copolymerized polyester having a compound with a polar group and/or cross-linking agent at 5 wt.% or more in the sheath, with an alkaline solution, (B) heats the fabric in a steam atmosphere, and preferably (C) irradiates the fabric with microwaves, to reduce weight of the polyester fabric by the alkali.

Abstract: PROBLEM TO BE SOLVED: To obtain a black-colored polyester-based fiber fabric hardly causing lowering of fastness and whitening due to abrasion, having various hues and rich in elegance and provide its production. SOLUTION: This fabric is composed of a polyester-based fiber in which both of pigment and disperse dye are contained and the fiber is composed of a pigment-dyed fiber. This method for producing the fabric comprises dyeing a fabric composed of the pigment-dyed polyester-based fiber obtained by mixing and dispersing pigment particles into a polyester-based polymer with a disperse dye and specifically comprises dissolving or decomposing a sheath component into a fabric comprising a core-sheath type conjugated fiber whose core component is a polyester containing a pigment and whose sheath component is composed of a polymer not containing pigment capable of readily being removed by dissolution or decomposition to remove the sheath component and then dyeing the fabric with a disperse dye.
