In the field of furniture sofa manufacturing, the quality and craftsmanship of leather directly affect the quality and value of sofas. The following is a detailed introduction to the common production process of furniture sofa leather.

Dyeing process is also an important part. According to customer needs and design requirements, choose suitable dyes to dye the leather. Modern dyeing technology can accurately control the depth and uniformity of color, making the leather present a rich color effect.
In order to enhance the performance and beauty of leather, finishing is also carried out. The finishing process includes primer, middle coating and top coating.
