PVC (imitation leather): It is rarely used on sofas, or only used on ultra-low-end sofas. PU (imitation leather): it is usually used for non-contact surfaces of offices and leather sofas.

Ultrafine leather and technical cloth will be used as contact fabrics for sofas. Polyurethane pays more attention to skin feeling, while technical cloth pays more attention to hand feeling. Many technological fabrics produced in reality are indeed fabric sensitive, which may be the real reason why technological fabrics are not called technological leather.

After cutting on the basis of superfine fibers, many fibers stand upright and can be touched by hands. Its matrix is very similar to dermis, so it can also be used as a control to distinguish whether it is polyurethane or PU.
