About the production of premium leather

After nearly 20 processes, a piece of natural cowhide has formed an advantageous leather fabric. In order to better understand this process, we will summarize it as follows:

1. Infiltration: Soak the leather in the drum to regain the water lost during the initial salinization.

2. Lime dipping: The first step of removing the fur and “bare” the leather.

3. Grease scraping: a mechanical step to remove residual fat under the skin to prevent chemical reactions and sour odor in the later leather.

4. Cut skin: Divide the epidermis into two or more layers. Only then can the upper layer become “full grain” leather.

5. Acid pickling: The chemical step of removing lime and opening the “grain” hole.

6. Tanning: Stop the organic decomposition process of the cortex to obtain chemical and biological stability.

7. Screening: Pick the best leather for Noah leather.

8. Shaving: Through the steps in the roller machine equipped with spiral blades, the thickness of the cortex is determined.

9. Retanning: Determine the final appearance of the leather: feel, texture, denseness, graininess.

10. Dyeing: Use dye to dye and apply evenly on the entire thickness.

11. Filling: Lubricates the leather layer to bring better elasticity, softness and resistance to pulling.

12. Drying: Eliminate humidity: Lay the skin on the preheating plate.

13. Air-drying: air-drying in a natural way to create the softness of leather.

14. Soften and moisten: soften and moisturize the fiber, further soften the leather’s feel.

15. Shrink: soften, moisturize and enhance the “touch” of leather.

16. Hand polishing: Improve the elegant and bright characteristics, which is called “thousand points” in the terms of tanned leather.

17. Pruning: Discard unusable parts.

18. Finishing: Determine the leather’s ability to resist friction, discoloration and stains.

19. Ironing and embossing: These two procedures are to make the “grain”  leather more uniform.

20. Measurement: The cortex is measured by electronic means to determine the size.
