Key Differences Rayon is created from cellulose derived from plants, making it a semi-synthetic fiber. It's known for its silk-like feel, draping quality, and breathability. Nylon, in contrast, is a fully synthetic fiber, produced entirely from petrochemicals, and is celebrated for its exceptional strength and durability.

Nylon fibers are stronger than rayon, producing a smooth fabric that's strong, elastic and abrasion-resistant. It's difficult to permanently mar the man-made fabric, because it's resistant to oil and chemical stains, and easy to wash. Unlike nylon, rayon is a highly absorbent fabric that can be more luxurious to the touch.

Both rayon and nylon are great alternatives for silk. Rayon is sensitive to water! Considering durability nylon fibers are more stable than that rayon. Nylon is more elastic than rayon meaning it is under stress its fibers will go back to their original form quicker.
