Embodiment 1

[0037] A method for making 3D three-dimensional effect leather, comprising the following steps:

[0038] A. Mesh screen production: Make a hollow mesh screen according to the required effect picture, and the empty part of the mesh screen is the required part of the effect picture;

[0039] B. Prepare the 3D layer slurry, and adjust the consistency to 6# Ford cup for 90±2 seconds, put the mesh screen on the leather base, pour the prepared 3D layer slurry on the mesh screen, and brush back and forth with a brush, Let the 3D layer slurry enter the skin surface from the hollow part on the screen; then remove the screen, dry and cool at 110-120°C to form a 3D layer;

[0040] C. Prepare the primer slurry, and adjust the consistency to 4# Ford cup for 48±3 seconds, and apply the prepared primer slurry on the surface of the 3D layer of the leather by roller coating, and the coating amount is 8.0±0.5 g / sqft; then dry and cool at 110-120°C to form an undercoat and wind up;

[0041] D....

Abstract

The invention discloses a manufacturing method of leather with a 3D effect. The manufacturing method comprises the following steps that A, a mesh sieve is manufactured; B, 3D layer slurry is prepared,the mesh sieve is placed on a leather blank, the prepared 3D slurry is poured on the mesh sieve and is brushed back and forth through a brush, the 3D layer slurry enters the surface of the leather blank from the hollowed part on the mesh sieve, the mesh sieve is taken down, drying and cooling are carried out, and a 3D layer is formed; C, base coat slurry is prepared, the surface of the 3D layer is coated with the base coat slurry, drying and cooling are carried out, a base coat layer is formed, and rolling is achieved; D, ironing is carried out; E, softening is carried out through throwing; and F, top layer slurry is prepared, the surface of the leather is coated with the top layer slurry, drying and cooling are carried out, and a top layer is formed. By means of the manufacturing methodof the leather with the 3D effect, the 3D effect can be formed, and the risk that suture pins are prone to being broken, and strength is insufficient does not exist, and the phenomenon that the leather is scrapped due to the fact that hot scalding fails is also avoided; and the leather is novel and attractive, and meanwhile the physical performance of traditional automotive trims is achieved.

Description

technical field [0001] The invention relates to the technical field of leather, in particular to a manufacturing method of 3D three-dimensional effect leather. Background technique [0002] The existing leather types have been diversified, such as conventional single-color embossed leather, two-color effect leather, oil wax color-changing leather, rubbed leather, pearlescent leather, etc. Some of these leathers are suitable for furniture and sofas, and some are suitable for Car seat cushions, the common feature of this kind of leather is to make different effects on the same plane, different types of products with different performances, what is lacking is that they cannot achieve the height of "private customization". Therefore, although consumers and designers of various car manufacturers have this idea and demand, it is often difficult to realize it. [0003] The next best thing is hot stamping and thorn rusting, but the problem is that these two methods are easy to dama...
