Embodiment 1

[0084] A leather surface finishing process comprises the following steps.

[0085] a, Resin impregnation: The leather is immersed in the resin impregnating liquid composed of resin emulsion and impregnating agent, so that the resin impregnating liquid penetrates into the deep part of the leather.

[0086] The dipping solution is set to contain in every 1000ml of water:

[0087] Comprehensive resin 50~100g,

[0088] Dye 10~15g,

[0089] Grease 6~8g,

[0090] Penetrant 8~10g;

[0091] Setting resin 15-30 g.

[0092] b. Primer coating: apply the primer solution on the surface of the leather. Specifically, use a brush or a plush brush to apply the primer solution to the surface of the leather.

[0093] Described priming liquid is set to contain in every 1000ml water:

[0094] Color paste 50~100g,

Abstract

The invention provides a leather surface coating and finishing process. The process comprises the following steps: a, resin impregnation: a leather is impregnated in a resin impregnation liquid consisting of a resin emulsion and an impregnating agent to make the resin impregnation liquid permeates deep parts of the leather; b, primary coating: surfaces of the leather are coated with a primary coating liquid; c, first mechanical finishing: surface finishing is performed on the primary-coated leather; d, middle coating: the surfaces of the first mechanical-finished leather are coated with a middle coating liquid; e, second mechanical finishing: polishing, patterning and coloring finishing are performed on the middle-coated leather in turn; f, final coating: the surfaces of the second mechanical-finished leather are coated with a final coating liquid; g, third mechanical finishing: brightness adjustment and surface hand-feel adjustment are performed on the final-coated leather; h, ironing; i, softness finishing: hand-feel finishing is performed on the ironed leather by using a vibration machine for softening leathers. The process consumes less chemical raw materials, has advantages of low pollution and environmental protection, and can improve quality of the leather significantly.

Description

technical field [0001] The invention relates to the technical field of leather production, in particular to a leather surface finishing process. Background technique [0002] With the development of society, leather products have played a vital role in people's lives, so the processing technology of leather products has become more and more important. Preparation, tanning and finishing are three important processes in leather production. [0003] Finishing is a decoration or makeup project on leather, which affects both the intrinsic performance and appearance of leather. In actual control, under the premise of not affecting the internal performance, we must pay attention to the control of the leather appearance performance by the finishing process, so that the leather has a good appearance performance, thereby improving the market sales prospect. In the prior art, the leather surface finishing process often uses more chemicals, especially when dealing with low-grade leath...
