From leather to sofa, you must know the production process

Speaking of leather sofas, probably no one is unfamiliar with them.

Moderate softness and easy cleaning make leather sofas preferred by people who pursue quality of life.

A piece of cowhide needs to go through 20 processes before it can become a good sofa material.

Below, Kaiqi Home Furnishing will explain it to you, so that interested friends can learn more about it.

1. Soaking: Soak the leather in a drum to regain the moisture lost during the initial salinization process.

2. Liming: The first step to remove the fur and “expose” the leather.

3. Fat scraping: a mechanical step to remove residual fat under the skin to prevent chemical reactions in the leather later and the appearance of sour odor, etc.

4. Cut the skin: Divide the epidermis into two or more layers.

The upper layer can become "full grain" leather.

5. Pickling: A chemical step that removes lime and opens the "grain surface" pores.

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

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

8. Shaving: Determine the thickness of the skin through steps in a roller machine equipped with spiral blades.

9. Retanning: determines the final appearance of the leather: feel, texture, density, and graininess.

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

11. Filling: Lubricates the skin layer to bring better elasticity, softness and pull resistance.

12. Drying: Eliminate humidity: lay the skin flat on the preheating plate.

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

14. Softening and wetting: soften and moisturize the fibers, further softening the feel of the leather.

15. Fulling: softens, moisturizes and improves the "feel" of leather.

16. Hand polishing: improves the elegant and bright characteristics, which is called "thousand points" in tanning terminology.

17. Pruning: discard unusable parts.

18. Finishing: determines the leather's ability to resist friction, fading and stains.

19. Ironing and embossing: These two procedures are to make the "grain" of Pelle Frau leather more uniform.

20. Measurement: The cortex is measured electronically to determine the size.

Only good leather and good craftsmanship can make a piece of cowhide suitable for processing into a good sofa.

The production process seems simple, but missing one link may affect the final performance of the leather.

Doing every step carefully is the ultimate guarantee of the quality of the product.
