Leather‑like fabrics and PVC synthetic leather or PU synthetic leather can be distinguished in two ways: First, examine the fabric’s back side—PVC synthetic leather and PU synthetic leather typically have a cloth backing (or knitted fabric backing), which is readily visible to the naked eye. Second, use the burn‑and‑melt test: take a small piece of the material and hold it over a flame; leather‑like fabric will not melt, whereas PVC synthetic leather and PU synthetic leather will soften and melt. The treatment of the base fabric also differs: Common textile‑based PVC is produced by first applying an adhesive coating to the fabric surface, then laminating a plastic film onto the coated fabric through a calendering process to ensure strong adhesion.
