Final answer:
The fabric imitating genuine suede is Ultrasuede, a synthetic material contrasting with natural wool, which is warm even when wet and made from animal fleece.
Step-by-step explanation:
The light to medium weight synthetic knit or woven fabric with a brushed nap that imitates genuine suede is known as Ultrasuede.
This fabric provides the look and feel of suede but is less expensive and easier to care for than the natural suede woven from animal fibers. Unlike wool, which comes from shearing sheep, llamas, or yaks and retains warmth even when wet, Ultrasuede is made from synthetic fibers. Natural wool is processed from the coats of animals which are sheared off, washed, and spun into yarn, whereas Ultrasuede is manufactured through a chemical process.
