The invention discloses an acidic rapid pad dyeing method for chinlon 56 fibers and chinlon 56 fabrics. The acidic rapid pad dyeing method for the chinlon 56 fibers and the chinlon 56 fabrics comprises the following steps that pad dyeing is conducted on the chinlon 56 fibers or the chinlon 56 fabrics through acid dye, neutral dye or reactive dye, wherein the content of terminating amino groups ofthe chinlon 56 fibers is 20 moL/106 gr to 80 moL/106 gr, the content of terminating carboxyl groups of the chinlon 56 fibers is 50 moL/106 gr to 110 moL/106 gr, and the degree of crystallinity is 30%-70%. The dyeing method has the advantages that (1) the dyeing effect is good, and a deep color is yielded; (2) the color fastness is good, the dyed fabrics have friction resistance, washing resistance, chlorine bleaching resistance, seawater resistance, perspiration resistance, soaping resistance and the like which can reach 3-4 levels or above, the solarization-resistant color fastness can reach6 levels or above, and the
