Rayon vs. Polyester — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on April 18, 2024
Rayon is a semi-synthetic fiber derived from cellulose, known for its silk-like feel and moisture-absorbing properties, while polyester is a fully synthetic fiber, prized for its durability, resistance to shrinking and wrinkling.

Key Differences
Rayon, originating from natural cellulose, often wood pulp, undergoes extensive processing to become a fiber that mimics natural textiles like cotton and silk in feel and drape. In contrast, polyester is crafted from petroleum-based chemicals, resulting in a fabric that is highly resistant to environmental conditions including moisture, making it extremely durable.
The manufacturing process of rayon involves the dissolution of cellulose and regenerating it into fibers, which makes it environmentally more taxing due to the chemicals used. Polyester, on the other hand, is synthesized through a chemical reaction involving coal, petroleum, air, and water, often considered less eco-friendly due to its non-biodegradable nature.
Rayon is breathable and comfortable against the skin, making it a popular choice for clothing intended to be worn in warm climates. Polyester, while less breathable, excels in insulation and is often used in fabrics for athletic wear and outdoor clothing because it wicks moisture away from the skin.
In terms of care, rayon can be more delicate, often requiring hand washing or dry cleaning to maintain its structure and appearance. Polyester is much easier to care for, as it is machine washable and resistant to shrinking and stretching, making it ideal for everyday and heavy-use garments.
While rayon offers a more natural aesthetic and comfort, it lacks the durability and easy maintenance of polyester, which remains a staple in the world of affordable and hard-wearing fabrics.

Common Curiosities
Which fabric is better for the environment?
Both fabrics have environmental drawbacks, but polyester's ability to be recycled may offer some sustainability benefits over rayon's chemical-intensive production process.
How do rayon and polyester differ in care and maintenance?
Rayon generally requires more delicate care, often needing hand washing and avoiding high heat, while polyester is low-maintenance, machine washable, and resistant to shrinking and wrinkling.
Is rayon suitable for outdoor garments?
While rayon is comfortable and breathable, it's less durable and weather-resistant compared to polyester, making it less suitable for harsh outdoor conditions.
How do the costs of rayon and polyester compare?
Polyester is generally cheaper to produce and purchase than rayon, making it more prevalent in low-cost textiles.
What are some common misconceptions about rayon and polyester?
A common misconception about rayon is that it's a completely natural fiber, while many believe polyester feels uncomfortable and cheap, though modern polyester fabrics can be quite soft and pleasant.
What is the main difference between rayon and polyester?
Rayon is a semi-synthetic, cellulose-based fabric known for its softness and breathability, whereas polyester is a fully synthetic, petroleum-based fabric known for its durability and moisture resistance.
Can rayon and polyester be recycled?
Polyester is more commonly recycled than rayon, which often involves chemical processes that can complicate recycling efforts.
Why might someone choose polyester over rayon?
Due to its durability, ease of care, and resistance to environmental conditions, making it suitable for everyday and active wear.
Which fabric is better for athletic wear?
Polyester is generally better for athletic wear due to its durability, quick-drying properties, and moisture-wicking capabilities.
What are the typical uses for rayon in textiles?
Rayon is often used in fashion garments like dresses, blouses, and scarves due to its softness and drape.
Can both fabrics be used for home furnishings?
Yes, both rayon and polyester are used in home furnishings, but polyester is often favored for items that require durability and easy maintenance, such as curtains and upholstery.
How do rayon and polyester impact thermal comfort?
Rayon tends to be cooler and more breathable, making it more comfortable in warm climates, while polyester's low breathability can make it feel warmer.
