[0013] Example

[0014] A production process for anti-fouling automotive interior leather, including batching → soaking → meat removal → liming → meat removal → deliming → softening → pickling → tanning → aging → shaving → rewetting → retanning →Neutralization→Dyeing, Electrostatic Conditioning→Squeeze Water Stretching→Wet Vibration→Vacuum Drying→Oscillation→Shattering→Bottom Coating→Charge Treatment→Embossing→Coloring Layer→Antifouling Top Layer→Antifouling Enhanced Layer→Measurement Warehousing,

[0015] The specific steps of the retanning are to first put the shaved white skin or blue skin into the drum to return to wet water and wash 2-3 times, and add the retanning filler low-VOC acrylic resin RV, low-VOC retanning agent FO, TARA Tannin extract, as well as high molecular weight aliphatic hydrocarbon fatliquors HP and AS, the total added amount is 5 wt%, 10 wt%, 6 wt%, 6 wt% and 6 wt%, and the reaction solid-liquid ratio is 200-230 %, the total reaction time is 2H. Through re...

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.

Description

technical field [0001] The invention relates to the field of industrial leather manufacturing, in particular to a production process of anti-fouling automotive interior leather. Background technique [0002] At present, mid-to-high-end cars are equipped with genuine leather interior leather (leather seat cushion leather, leather steering wheel leather, etc.). Flowering, coloring, top coating and other processes, the existing automotive interior leather generally has the following problems: [0003] 1. In order to meet the almost stringent performance and test requirements of automobile seat cushion leather, the leather products used for automobile seat cushions at home and abroad have always appeared hard and monotonous in appearance, lacking elasticity and softness, and losing the natural product that leather should have. the natural characteristics of [0004] 2. Bright or light-colored leather has obvious defects in use, that is, it is not resistant to dirt, and has rec...
