Speaking of leather sofas, it is estimated that no one feels strange. Moderate softness combined with easy-to-clean features make leather sofas preferred by people who are looking for quality of life. A piece of cowhide has to go through 20 processes to stop the use of a good sofa. 1. Infiltration: Soak the leather in the drum and regain the moisture lost during the initial salinization. 2, liming: the first step to remove the fur, leather "naked". 3, scraping grease: mechanical steps to remove residual fat under the skin, to prevent chemical reactions in the later leather, acid odor and so on. 4, split skin: the skin is divided into two or more layers. The upper layer can become a "full grain" leather. 5. Pickling: The chemical step of removing lime and opening the "grain" pores. 6. Tanning: Stop the cortical organic decomposition process to obtain chemical and biological stability. 7. Screening: Pick the best leather for Noah leather. 8. Shaving: The thickness of the skin layer is determined by the steps in a roller machine equipped with spiral blades. 9, reclamation: determine the final appearance of leather: feel, texture, thick, grainy. 10. Dyeing: Dyeing with dye and evenly spreading over the entire thickness. 11. Filling: Lubricate the skin layer for better elasticity, softness and pull resistance. 12. Drying: Eliminate humidity: Spread the cortex on the preheating plate. 13, air drying: air drying in a natural way, to create the softness of leather. 14. Pull soft and wet: soften and moisturize the fiber, further softening the feel of the leather. 15. Fleece: softens, moisturizes and enhances the "feel" of leather. 16, hand-polished: to improve the elegant light characteristics, called "thousands" in the terminology of suede. 17. Trim: Discard the parts that cannot be used. 18. Finishing: Determine the ability of the leather to resist abrasion, resistance to discoloration and stain resistance. 19. Ironing and embossing: Both procedures are designed to make the “grain†of Pelle Frau® leather more uniform. 20. Measurement: The cortex is measured electronically to determine the size. Good leather plus good craftsmanship can make a piece of cowhide to make a material suitable for processing into a good sofa. The craftsmanship seems simple, but the lack of one of them can affect the performance of the final cortex. Doing every step of the heart is the ultimate guarantee of the quality of the product.
