The invention relates to the technical field of printing technology, in particular to a nylon fabric and a printing production technology thereof and application of nylon special heat transfer ink. The printing production technology of the nylon fabric comprises the following steps of using a digital printing machine to print the heat transfer ink onto transfer paper, and transferring a printing pattern from the transfer paper to the nylon fabric by a heat transfer technology, so as to obtain a nylon printing fabric material, wherein the nylon special heat transfer ink is prepared from the following raw materials in percentage by weight: 20 to 40% of dispersive dye paste, 1 to 10% of color fixing agent, 10 to 30% of moisturizing agent, 0.01 to 0.1% of surface tension adjuster, 0.01 to 0.5% of defoaming agent, 0.01 to 0.5% of preservative, and the balance of deionized water. The printing production technology has the advantages that the clean production of printing procedure of nylon fabric material is realized, the zero-drainage goal of industrial sewage is realized, the printing effect is good, the color fastness of a finished product is high, and various properties are respectively higher than the market use requirements.
