Abstract

The invention relates to the field of the manufacturing of industrial leather, and in particular relates to a production process of anti-staining automobile interior leather. The production process comprises the steps of soaking, fleshing, liming, fleshing splitting, deliming, softening, pickling, tanning, aging, shaving, conditioning, retanning, neutralizing, dyeing, electrostatic conditioning, wringing stretching, wet vibrating, vacuum drying, vibrating, milling, bottom layer coating, electrostatic treatment, knurling, intermediate painting, anti-staining top layer preparing, anti-staining reinforced layer preparing, measuring and warehousing, wherein anti-staining top layer paint and anti-staining reinforced layer paint are respectively proportioned according to the appropriate components and then are sprayed onto the leather surface according to the appropriate coating amount, and then the leather is dried. Through the combined action of different functions, not only is the anti-staining performance strong, but also the anti-staining effect is remarkable, stains which are not repelled are easy to scrub and clean due to the difficulty in combination and permeation, and the automobile interior leather which is anti-staining and easy to clean can be achieved.
