Problems solved by technology

[0003] The embossing effect of three-dimensional embossed leather is closely related to the finishing process. If the filling material is not used properly in the finishing process, not only will the embossing effect be poor and the three-dimensional effect will not be obvious, but the leather performance will also be reduced.
In addition, in the existing leather base coating, in order to ensure the good embossing effect and performance of the leather, it is still necessary to cooperate with the adhesive resin in the case of using a penetrating agent to complete the surface of the leather that is difficult to wet. finishing work

Abstract

The invention relates to a three-dimensional embossed leather manufacturing method and belongs to the technical field of leather manufacturing. The method includes steps that the raw leather is sequentially subjected to leather grinding, spray filling, roll coating filling, static drying, rolling finish, embossing plate, surface grinding, and softening to become three-dimensional embossed leather,specifically, the step of spray filling includes that spraying a first filling on the surface of the ground raw leather; the spray quality is 5-10 g per square foot; and the first filling is composedof, by mass, 50%-55% of water, 30%-40% of a first aqueous acrylic resin dispersion, and 7%-15% of a first penetrant, and the water, the first aqueous acrylic resin dispersion and the first penetrantaccount for 100% in total. The finished three-dimensional embossed leather according to the method has a strong sense of three-dimensionality, has good peeling strength and a good coating effect, andthe method is relatively simple and convenient to promote.

Description

technical field [0001] The invention belongs to the technical field of leather production, and in particular relates to a production method of three-dimensional embossed leather. Background technique [0002] Embossed leather is a kind of high-end leather that is widely used in leather. It presses the pattern on the leather surface through the pressing process, and supplements other processes to permanently press the pattern on the leather surface to form embossed leather with special lines. Embossed leather is widely used in clothing, luggage and other fields because of its grand appearance and high quality. [0003] The embossing effect of three-dimensional embossed leather is closely related to the finishing process. If the filler is used improperly in the finishing process, not only will the embossing effect be poor and the three-dimensional effect will not be obvious, but the leather performance will also be reduced. In addition, in the existing leather base coating, i...
