Guoyuan’s wet-process embossed split leather combines a wet-processed cow split leather base with an additional embossing stage to create a defined surface pattern and controlled finished appearance.
The wet process forms a microporous coated layer on the split leather, while embossing adds the selected grain geometry. Subsequent finishing establishes the final color, gloss and surface character.
Guoyuan’s wet-process embossed split leather starts with a cow split leather base that is processed through a wet coagulation system to form a microporous surface layer.
An additional embossing stage then introduces the selected grain pattern. Further finishing controls the final color, gloss, contrast and overall surface appearance.
The construction can be understood as:
The split leather base contributes to the required body and flexibility, while the embossing stage establishes the surface geometry.
Because the base construction, coating, embossing and finishing work together, the grain should always be evaluated on the complete finished material, rather than from an embossing plate, photograph or small pattern reference alone.
The wet-process layer has a microporous structure and can provide a degree of air permeability. However, breathability is not defined by microporosity alone and should be evaluated according to the finished construction and application requirements.
Water resistance is a separate development requirement. If water resistance is required, it can be developed and specified as an additional finishing target.
For the underlying material direction, see Wet-Process Split Leather.
The embossing pattern is not only a surface decoration. Pattern scale, relief, direction and repetition can significantly change how a finished leather panel looks and behaves.
| Grain Direction | Visual Effect | Selection Priority |
| Pebbled / Litchi Grain | Rounded, distinct surface pattern with a structured textured appearance | Pebble size, spacing and definition |
| Cross-Grain | Directional, intersecting texture with a more geometric surface character | Line spacing, crossing pattern and orientation |
| Natural-Grain Effect | Irregular, leather-inspired appearance with less uniform visual repetition | Pattern scale, irregularity and repetition |
| Milled-Look Grain | Relaxed, broken-grain appearance with a softer visual rhythm | Relief, pattern distribution and appearance when folded |
| Animal-Pattern Embossing | Decorative animal-inspired surface such as crocodile, lizard, snake or other available references | Pattern scale, repeat, relief, panel layout and visual definition |
Animal-pattern embossing is developed as a surface pattern on cow split leather. It does not change the underlying material into genuine crocodile, snake, lizard or other exotic leather.
These descriptions identify general visual directions. Available patterns, pattern scale and final appearance are confirmed through physical sampling.
A grain name is only the starting point. For production development, the embossing should be defined through several measurable or visually controlled characteristics.
A pattern that looks balanced on a small swatch can appear very different across a large bag panel, shoe quarter or wallet body.
Embossing depth affects the contrast between raised and recessed areas.
Directional textures require a defined cutting orientation.
Embossed surfaces contain both raised and recessed areas, so light interacts with the grain differently across the surface.
The appearance of an embossed grain can change when the leather is folded, curved or formed.

Existing pattern availability and the feasibility of a new embossing pattern are reviewed before sampling.
Where new tooling is required, pattern development and tooling requirements form part of the development review.
An embossing pattern should not be evaluated only as a small leather swatch.
The final appearance can change according to component size, forming direction, bending and the way multiple panels are assembled.
Inspect the grain across:
A pattern that looks uniform on a small sample may show visible repetition or scale differences across a larger panel.

The grain should remain consistent with the intended product appearance after the material has been formed.

When requesting a sample, provide:
For animal-pattern development, also indicate the preferred pattern type, scale, repeat and level of relief.
Guoyuan’s technical team can then review the wet-process split construction, embossing direction and finishing route before confirming the sampling approach.
Bring your grain reference and product requirements to Guoyuan.
Our team can evaluate the cow split base, wet-process construction, embossing pattern, grain scale, relief, finish, color and application requirements together to develop a finished material suitable for your product.
